On the 2011-2021 Jeep Grand Cherokee 5.7L HEMI V8 with MDS/VVT, a persistent tick and cylinder misfire on a 5.7L Grand Cherokee can be consistent with valvetrain damage, but those symptoms do not identify a failed MDS lifter or worn camshaft by themselves. Exhaust-manifold leaks, ignition or injector faults, oil-pressure problems, rocker/pushrod faults, compression loss, and other mechanical conditions can overlap. FCA has published a cam/lifter inspection note for certain 5.7L MDS police Charger, Durango, and Ram 1500 vehicles, but that document does not establish the prior card's blanket Grand Cherokee year, mileage, DTC, or part-set claims.
Common Symptoms
Persistent engine-speed tick that remains after warm-up
Cylinder-specific or random misfire
Rough running or reduced power
Abnormal rocker motion or confirmed cam-lobe/lifter-roller damage
Metal debris found during oil-filter inspection
How to Fix
Record the exact DTCs and freeze-frame data, verify oil level and mechanical oil pressure, and identify whether the sound is from the exhaust manifold or inside the valvetrain. Diagnose ignition and injector causes for the affected cylinder, then perform factory compression and cylinder-leakage testing as indicated. If the evidence remains mechanical, inspect rocker motion, pushrods, lifter rollers, and cam lobes using service information for the exact VIN and engine build. Only after lifter or cam damage is physically confirmed should a technician select the correct mix of deactivating and standard lifters, yokes, camshaft, gaskets, torque-to-yield fasteners, and any contamination-related work. Stop driving and obtain professional diagnosis if the oil-pressure warning appears, the malfunction lamp flashes, severe misfire develops, or metal is found in the oil/filter.
Owner tips & cautions
WarningDo not buy a camshaft or lifter kit from a tick, a generic misfire code, or the old card's part list. The correct repair depends on physical inspection and the VIN-specific MDS valvetrain configuration.
TipRule out the exhaust-manifold cold-tick condition first. FCA has a separate crack-inspection path and updated manifold kits for covered 2019-2022 5.7L vehicles.

On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6, early (2011-2013) 3.6L Pentastar engines have a defective left-bank cylinder head with excessive valve seat/guide wear, attributed to incompatible head materials. The wear causes leak-down and misfires concentrated on the left bank — cylinders 2, 4, and 6 — often with a ticking valvetrain noise. Chrysler never issued a safety recall but acknowledged the problem with TSB 09-002-14 and warranty extension X56, covering the left cylinder head for 10 years / 150,000 miles. Buyers are advised to confirm the left head is stamped 2062 (day 206 of 2012) or later, indicating the corrected casting.
Replace the affected (left) cylinder head with the updated revised-casting part, including new gaskets and hardware, per TSB 09-002-14. Verify warranty extension X56 coverage (10yr/150k) before paying out of pocket. Diagnose by pulling misfire codes on even-numbered (left-bank) cylinders and performing a leak-down/compression test; confirm the head casting date stamp on used/early engines.

On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), fCA TSB 09-002-14 Rev. B covers 2011-2013 WK Grand Cherokee vehicles with the 3.6L ERB engine when P0300, P0302, P0304, or P0306 is stored. The bulletin's decision point is excessive leakage in the cylinder that set the misfire, not a tick, mileage estimate, casting date, or assumption that every left-bank misfire needs a cylinder head. X56 was an extended warranty, not a safety recall. Warranty bulletin D-14-12 set original coverage at 10 years or 150,000 miles from the vehicle's in-service date for eligible VINs; current eligibility must be checked and should not be described as an automatic free repair in 2026.
Malfunction indicator lamp with P0300, P0302, P0304, and/or P0306
Rough running or misfire on an affected cylinder
Cylinder leakage of 25 percent or greater on the misfiring cylinder
How to Fix
Save the misfire DTC and freeze-frame data and first exclude normal ignition, injector, wiring, fuel, and other mechanical causes as appropriate. For a vehicle within the FCA bulletin path, perform a cylinder leakage test on the cylinder that set the misfire. FCA directs left-cylinder-head replacement only when that cylinder shows 25 percent or greater leakage; below 25 percent, the bulletin does not apply and normal diagnosis continues. Check the VIN in the dealer system for any remaining X56 status or prior repair history. If replacement is required outside coverage, have the technician confirm the current Mopar supersession, complete gasket/bolt/seal list, machine condition, core terms, and all one-time-use components for that VIN before ordering. Recheck compression/leakage, misfire counts, cooling, oil level, and leaks after repair.
Owner tips & cautions
WarningDo not order a cylinder head from a tick or misfire code alone. FCA requires leakage testing on the cylinder that set the DTC and a result of at least 25 percent before this bulletin's head-replacement path applies.
TipAsk the dealer to check the VIN for X56 status and repair history even though the original time limit may have expired; coverage was VIN-, time-, and mileage-dependent.
On the 2011-2014 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), original factory oil-filter adapter, chrysler changed the 3.6L engine oil-filter adapter and filter element for model year 2014. The 2011-2013 and 2014 designs are physically different and are not interchangeable; Chrysler warns that installing the wrong filter causes permanent engine damage. The included O-ring must also be used because the wrong seal can leak and damage the adapter. The previous card duplicated the separate adapter-leak record, claimed a common plastic-housing failure across 2011-2023 WK2 and WL vehicles, said Chrysler discontinued the plastic assembly, and directed every owner to an aluminum replacement without separating model year or installed housing.
Common Symptoms
A replacement filter does not match the element removed from the original housing
The filter or supplied O-ring will not seat correctly
A service record lists the 2011-2013 element for a 2014 vehicle or the reverse
How to Fix
Confirm the model year and inspect which oil-filter adapter is actually installed. For an original factory adapter, use the early element family for 2011-2013 and the later element family for 2014; never interchange them. Use only the O-ring supplied with the selected filter and install it in the correct groove. The two exact product links below are year-split and apply only to original factory-style housings. If an aftermarket aluminum adapter or conversion has been installed, do not use these links from model year alone: identify the housing manufacturer and part number and use the filter and seal that manufacturer specifies, because ShowMeTheParts explicitly lists different elements for some aftermarket housings. If a wrong filter was installed, correct it and have the engine assessed if it was operated or has abnormal noise or oil-pressure concerns.
Owner tips & cautions
WarningThe 2011-2013 and 2014 filters are not interchangeable. The two product links are intentionally separated by model year and original factory housing.
WarningAn aftermarket aluminum housing can change the required filter. Identify that housing and follow its own application instructions instead of ordering from the vehicle year alone.
TipCompare the new element and supplied O-ring with the parts removed before installation; use only the seal included with the correct filter.
On the 2011-2023 Jeep Grand Cherokee, wK2 (and 5th-gen WL) Grand Cherokees use hydraulic fluid-filled engine mounts. The mounts commonly fail — the internal fluid leaks out (visible reddish-brown residue on the subframe) and the rubber degrades — producing a pronounced vibration felt through the steering wheel, seat, and floor at idle in gear, plus a clunk on acceleration or gear engagement. It is especially prevalent on the 3.6L Pentastar left/front mount, and forums note 2021-2022 units failing repeatedly; a service bulletin exists for the mounts. It is frequently confused with driveline vibration, so both should be checked together.
Heavy vibration at idle, worse in Drive/Reverse at a stop
Clunk/thump on acceleration or shifting into gear
Reddish-brown fluid residue on the subframe under the engine
Vibration through steering wheel and floor
Engine 'settling' movement felt in cabin
Repeat failures on newer model years
How to Fix
Inspect the engine mounts for fluid weepage and separated rubber; wet/leaking hydraulic mounts should be replaced (replace in pairs on higher-mileage trucks and inspect the transmission mount at the same time). Use OEM Mopar hydraulic mounts rather than solid rubber aftermarket units, which reintroduce vibration. Re-verify idle smoothness in gear after replacement and confirm the driveshaft/mounts aren't jointly contributing.

On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), low engine oil between changes on a 2011-2013 Grand Cherokee 3.6L does not by itself prove that the PCV valve or hose has failed. Chrysler's gasoline-engine diagnostic bulletin requires a formal oil-consumption test first. Only when the vehicle fails that test does the procedure move to checking the complete PCV system for restriction, the correct valve part, and the correct vacuum source; if the PCV system is correct, compression and cylinder leak-down testing follow. The previous card described the PCV system as the primary and most common cause, prescribed an unsupported 30,000-mile replacement interval, recommended a catch can, and attached P052E and P0300 without reviewed FCA support.
Common Symptoms
Engine oil level drops between documented checks
Oil must be added before the scheduled oil change
The vehicle fails Chrysler's formal oil-consumption test
How to Fix
Verify the oil was filled to the correct level and document mileage and oil added under Chrysler's oil-consumption test procedure. If the vehicle passes the test, do not replace PCV parts for this concern. If it fails, inspect the full PCV path for restriction, confirm the installed valve is the correct part for the VIN and engine, and verify the correct intake-vacuum source; repair only a fault found in those checks. If the PCV system is correct, record a cylinder-compression test and perform a leak-down test using the applicable service specifications. Also diagnose any visible external leak separately. Do not order a PCV valve, revised hose, or catch can from oil use alone, and do not treat P052E or P0300 as part of this card without an actual scan and code-specific diagnosis.
Owner tips & cautions
TipRecord the exact oil level, mileage, and quantity added. A repeatable consumption test is more useful than guessing from one low reading.
WarningDo not treat the PCV valve as the default repair. Chrysler's sequence checks it only after a failed oil-consumption test and moves to compression and leak-down testing when PCV is correct.
WarningThe old 30,000-mile PCV interval, catch-can recommendation, P052E/P0300 mapping, and universal valve/hose purchases were removed because the reviewed FCA evidence does not support them for this card.
On the 2011-2022 Jeep Grand Cherokee, the electronic-throttle-control warning lamp and reduced-power or limp mode are protective responses, not a diagnosis that the throttle body has failed. Depending on the stored DTC and application, the factory path may lead to a stuck or contaminated throttle plate, throttle motor or position-sensor response, accelerator-pedal sensors, a five-volt supply fault, damaged wiring or terminals, or a PCM issue. The old card's thermostat shopping claim is not part of the cited ETC diagnostic path, and a throttle body should not be ordered from the warning lamp alone.
One or more throttle, pedal, voltage-supply, or actuator DTCs
How to Fix
Before clearing anything, record every PCM DTC, pending code, freeze-frame value, battery voltage, temperature, and the exact conditions under which reduced power occurred. Diagnose prerequisite five-volt-supply, throttle-position, accelerator-pedal, or other active faults in the order specified by the current factory procedure for that VIN and engine. For a P2111-style fault, inspect the throttle plate for binding or foreign material and run the scan-tool throttle-follower test, then test the motor circuits, connector terminals, and wiring as directed. For a pedal-correlation code such as P2138, follow the accelerator-pedal sensor and circuit procedure instead. Replace and relearn a throttle body only when the applicable test condemns it; do not buy a thermostat as an ETC rule-out part.
Owner tips & cautions
WarningAn ETC lamp does not prove the throttle body failed. Save the codes and freeze-frame data before clearing them or disconnecting the battery.
TipAsk the shop to name the exact DTC and the failed factory test step before approving any throttle-body, pedal, wiring, or PCM part.
On the 2011-2021 Jeep Grand Cherokee, hEMI-equipped Grand Cherokees can develop the characteristic MDS lifter tick. This ticking noise is most noticeable at idle and during light throttle. While often not immediately harmful, it indicates lifter wear from the MDS cylinder deactivation system.
Use quality synthetic oil meeting Chrysler MS-6395 spec. Consider MDS delete kit for permanent solution. Some owners have replaced lifters and camshaft under extended warranty. Regular oil changes help minimize tick progression.
Owner tips & cautions
TipRegular oil changes help minimize tick progression.

On the 2011-2014 Jeep Grand Cherokee, grand Cherokees with electro-hydraulic power steering subject the alternator to cyclical electrical loads that cause thermal failure of the internal diodes. The alternator can fail suddenly, stalling the vehicle without warning and, in some cases, short-circuiting and causing an under-hood fire. Multiple NHTSA campaigns cover the 160/180/220-amp units.
Have the applicable recall performed (NHTSA 14V-634 for 160-amp 3.6L units, and 17V-435 for EHPS-equipped 5.7L/3.6L vehicles): dealers inspect and replace the alternator free of charge. Out of warranty, replace the alternator with an updated unit; budget roughly $400-$700 including labor.
On the 2011-2021 Jeep Grand Cherokee, grand Cherokees equipped with factory HID/xenon projector headlights are commonly reported for dim or color-shifted low beams as the bulbs age, single-side bulb or ballast failures, and internal lens condensation. Per Chrysler service guidance, some condensation inside vented HID housings is considered normal and should clear as the bulbs heat up; however, persistent moisture from a failed lens-to-housing seal can corrode reflective surfaces and shorten bulb life. Older assemblies also haze/yellow, further reducing output.
For dim/aged output replace the HID bulbs (and ballast if a bulb fails to strike); match bulbs in pairs for even color. For mechanical high/low projector faults inspect the projector shutter solenoid. If condensation does not clear after running the lights, replace the headlight assembly due to a failed seal. Restore hazed lenses or replace assemblies as needed.

On the 2005-2013 Jeep Grand Cherokee, the Mercedes-derived W5A580 (NAG1) 5-speed automatic used in WK and early WK2 Grand Cherokees is mechanically strong but suffers well-documented electronic and fluid-related failures. Faulty conductor-plate speed sensors and shift-pressure solenoids drop the transmission into limp mode (stuck in a single gear). Contaminated or degraded fluid (including water intrusion past the dipstick/fill-tube seal) causes torque-converter-clutch shudder, harsh or delayed shifts, and a knock on coasting downshifts. The 13-pin connector adapter can also leak, wicking fluid into the harness by capillary action.
Scan for transmission codes; for limp mode inspect/replace the conductor plate (with integrated speed sensors) and any failed shift solenoid, and replace the 13-pin connector adapter/seal if leaking. Perform a full fluid-and-filter service with the correct ATF (MB 236.x / Mopar spec). Address water intrusion at the fill tube. Severe internal damage from prolonged shudder may require a rebuild.

On the 2011-2021 Jeep Grand Cherokee, quadra-Lift is a closed, electronically controlled air-suspension system, so a Service Air Suspension message, a low corner, or a denied height change does not identify one universal failed part. The factory diagnostic path covers electrical and communication faults, fuses and voltage, pinched or damaged lines, leaking springs, disconnected sensor linkages, water or blockage in the compressor intake, air-mass loss, valve/compressor faults, software, and the Air Suspension Control Module. The prior card also incorrectly treated SRT and Trackhawk as automatic Quadra-Lift applications; applicability should be established by sales code SER or the vehicle build sheet.
Common Symptoms
Service Air Suspension message
One corner or one axle sits low
Ride-height change is slow, denied, or inoperative
Quadra-Lift height indicators flash or normal leveling is disabled
How to Fix
Confirm the vehicle is equipped with Quadra-Lift sales code SER, record the exact ASCM DTCs and environmental data, and check VIN/build-date-specific FCA bulletins before ordering hardware. Follow the factory sequence: repair voltage or communication faults first; inspect fuses, air lines, springs, height-sensor linkages, compressor intake/filter, and visible plumbing; then use a capable scan tool to run the Air Mass and Air Ride Height routines and follow the DTC-specific tree. On 2011-2012 vehicles built before May 1, 2012, U0415-00 or C159E-15 with a Service Air Suspension message may be addressed by FCA TSB 08-034-12's ASCM software update. Replace only the component proven failed. A completely depleted system requires the specified refill equipment, scan-tool procedure, and purity-class-5 nitrogen; do not fill it with ordinary shop air or shotgun-replace springs, sensors, and the compressor.
Owner tips & cautions
WarningDo not replace a compressor because the vehicle sits low. A leaking spring or line, sensor/linkage fault, intake restriction, valve fault, low system air mass, or software condition can create overlapping symptoms and can overwork a replacement compressor.
TipAsk the shop to record the ASCM DTCs, air-mass result, ride-height routine result, and verified leak location. Those findings should select the part, not a generic model-level shopping list.

On the 2011-2021 Jeep Grand Cherokee, front wheel hub/bearing assemblies are a recurring wear failure on the WK2 Grand Cherokee, producing a humming, whining, or growling noise that rises with road speed (commonly noticeable from about 35-50 mph) and often changes pitch when the vehicle is loaded or steered left/right. The integrated hub/bearing units wear relatively early, and owners frequently report needing replacement on one or both front corners. Left unaddressed the bearing can develop play and eventually trigger ABS/traction warnings or, in severe cases, lead to hub damage.
Humming/whining/growling that increases with speed
Noise changes pitch when turning left or right
Vibration felt through floor/steering at highway speed
Possible ABS or traction-control light if bearing develops play
How to Fix
Confirm the failing corner by listening for the speed-dependent hum and checking for bearing play; the noise typically worsens when turning toward the good side. Replace the affected front hub/bearing assembly (sold as a complete unit). Replacing in pairs is common when both have similar mileage. Verify ABS sensor function after replacement.

On the 2011-2021 Jeep Grand Cherokee, a WK2 front-end clunk over bumps, during braking, or while steering can come from more than the sway-bar links or lower control arms named in the old card. The source can vary with loading and may involve a stabilizer link or bushing, control-arm bushing, ball joint, tie-rod end, shock or upper mount, wheel bearing, loose fastener, brake hardware, or another nearby component. Standard and high-performance suspension packages also use different side-specific parts. Ordering four components from the noise alone risks replacing good parts while leaving a safety-relevant loose joint in service.
Common Symptoms
Clunk or knock from the front over bumps
Noise during braking, acceleration, or steering load changes
Possible looseness, uneven tire wear, or steering change if a joint or bushing is worn
How to Fix
Record when the noise occurs and reproduce it safely on a controlled road test. With the vehicle supported according to the factory procedure, inspect wheel and tire security, brake hardware, steering linkage, stabilizer links and bushings, control-arm bushings, upper and lower ball joints, shocks and mounts, wheel bearings, subframe attachment, and nearby shields or loose hardware. Check joints and bushings in the loaded and unloaded positions specified by the service manual, and use chassis ears or controlled isolation when visual play is not obvious. If steering looseness, wheel movement, instability, or a damaged joint is present, stop driving until repaired. Replace only the confirmed failed component using the VIN, side, suspension sales code, and current supersession; torque at the specified ride-height condition and perform an alignment when the repair procedure requires it.
Owner tips & cautions
WarningDo not assume a sway-bar link or control arm from the sound alone. Steering looseness, wheel movement, or a damaged ball joint requires immediate inspection before more driving.
TipAsk the shop to identify the exact failed joint or bushing, side, and suspension sales code and to show the measured play or isolated noise before parts are ordered.
On the 2011-2021 Jeep Grand Cherokee, grand Cherokee 4x4 differentials (and the transfer case) are a known spot for pinion-seal leaks — owners find gear oil weeping where the driveshaft meets the diff, leaving puddles and, if ignored, running the diff low on lube. A low/contaminated differential then produces a speed-related whine or howl (rising on acceleration or deceleration depending on which gear/bearing is loaded). RepairPal documents many pinion-seal/transfer-case leak cases on the platform. A caution: careless seal replacement (over-torquing the pinion nut and crushing the collapsible spacer) destroys pinion-bearing preload, so the repair must be done correctly.
Gear-oil puddle/residue at the driveshaft-to-differential joint
Speed-dependent whine or howl from front or rear axle
Whine changes on acceleration vs deceleration
Low differential fluid level
Metal glitter on the diff fill plug (advanced wear)
Transfer-case output seal also weeping
How to Fix
Inspect the front and rear diff pinion flanges and transfer-case output for gear-oil weepage; confirm fluid level. Replace the leaking pinion seal, marking pinion-nut position/turns to preserve preload (or setting new preload with a fresh crush sleeve) to avoid bearing damage. If gear whine is already present from prior low-lube running, evaluate the ring/pinion and bearings and refill with the correct spec gear oil. Address any transfer-case seal leaks at the same time.

On the 2011-2021 Jeep Grand Cherokee, grand Cherokees with the two-speed Quadra-Trac II / Quadra-Drive II transfer cases throw a 'Service 4WD System' message when the transfer-case shift actuator motor (or the transfer-case control module) fails, leaving the vehicle unable to engage Low range or Neutral and sometimes producing a grinding noise. Owners and shops report it is difficult to diagnose: replacing the actuator motor does not always fix it, and some vehicles ultimately need a transfer case. Codes such as C140F are associated with the actuator failure. It is a high-demand complaint because the warning is alarming and the off-road/low-range function is lost.
Scan for transfer-case actuator/control codes (e.g., C140F) before parts replacement. The shift motor is accessible after removing the belly skid guards (four bolts and a connector) and is the first replacement; if the fault persists, test the transfer case control module and wiring, and inspect the actuator's internal encoder ring/case for damage before condemning the whole transfer case. Verify any applicable recall coverage tied to the fault code.

On the 2011-2021 Jeep Grand Cherokee, wK2 Grand Cherokees commonly develop a speed-dependent driveline vibration or shudder felt through the floor/seat, typically appearing around 45-75 mph and often worse under light acceleration or on deceleration. The rear driveshaft uses CV-style joints and a splined slip section; grease can migrate out of the slip joint and collect in the rubber accordion boot, the CV joints wear or bind, and the center support/CV angles fall out of spec, all producing the vibration. Motor and transmission mounts (which also fail on these trucks) can amplify or mimic the symptom, complicating diagnosis. Heavier V8/SRT/Trackhawk models with more torque tend to surface it sooner.
Vibration or shudder felt in floor/seat at 45-75 mph
Worse under light throttle or when decelerating
Droning/humming that rises with road speed
Grease slung inside the driveshaft boot area
Clunk on takeoff if joints are worn
Vibration reduced after mount replacement (partial cause)
How to Fix
Diagnose by roadtest and by inspecting the rear propshaft: clean redistributed grease out of the slip-joint boot and re-grease the slip yoke, check CV joints for play/binding, and verify driveshaft/pinion angles and center bearing condition. Rebalance or replace the rear driveshaft assembly if joints are worn. Confirm engine and transmission mounts are not collapsed (a frequent contributor). Replacing a worn rear driveshaft or reconditioning the slip joint typically resolves it.

On the 2011-2021 Jeep Grand Cherokee 3.6L Pentastar V6, the integrated plastic-housing thermostat on the 3.6L Pentastar commonly fails stuck open or opens too early, so the engine never fully reaches operating temperature. The ECM sets P0128 (coolant temp below thermostat regulating temperature), and the driver gets weak cabin heat, sluggish warm-up, lower fuel economy, and increased oil contamination. It is one of the most frequently searched check-engine complaints on these engines and is an inexpensive, DIY-friendly fix.
Replace the thermostat (integrated into the Mopar thermostat housing, e.g. 5184651AH-family for 3.6L) using an OEM-grade unit, then properly bleed all air from the cooling system via the bleeder. Verify the coolant temperature sensor and confirm correct coolant level before condemning the thermostat. Clear P0128 and confirm the engine reaches full temp over a few drive cycles.

On the 2011-2021 Jeep Grand Cherokee 3.6L Pentastar V6, on the WK2 Jeep Grand Cherokee with the 3.6L Pentastar V6, P0171 (and frequently P0174 alongside it) is most commonly triggered by unmetered air entering the engine through a deteriorated intake manifold gasket or a cracked/warped plastic intake manifold. The Pentastar's rubber-and-plastic gaskets become brittle from years of heat cycling and crack, letting in extra air so the upstream O2 sensors report a persistent lean condition. A closely related contributor is the notorious oil filter housing/oil cooler adapter in the engine valley (under the intake manifold) cracking, which is usually addressed at the same time since the intake has to come off. Some early cases are resolved with a PCM software update before parts are replaced.
Smoke-test the intake to confirm the vacuum leak, then replace the intake manifold gasket set (and the plastic intake manifold itself if cracked/warped). Because access requires removing the intake, shops commonly replace the leak-prone oil filter housing at the same time. Check for any available PCM software update first, and verify fuel trims return to normal after the repair.
On the 2011-2021 Jeep Grand Cherokee, the WK2 uses a saddle-style fuel tank with two fuel-level senders (one per lobe). The sender floats/rheostats stick or wear, and the PCM flags a sender that no longer tracks fuel consumption, setting P2068 (or related P0461/P0463) and a 'Service Fuel Level Sensor' message. Symptoms include a gauge stuck on Full or Empty, wildly bouncing readings, and an inaccurate Distance-to-Empty. It usually doesn't affect running but can strand an owner who trusts a stuck-full gauge, and it commonly requires dropping the tank to access the sender/module.
Scan for P2068/P0461/P0463 and confirm which sender is faulty. Inspect the sender for a stuck float and check connector/wiring; some intermittent stuck floats free up, but a failed sender requires replacement of the affected fuel-level sensor/sender module (often the in-tank pump/sender assembly), which typically means lowering the fuel tank. Recalibrate/verify gauge sweep after repair.

On the 2005-2021 Jeep Grand Cherokee, warm air, a charge that does not last, or a compressor that will not engage can be consistent with a refrigerant leak, but those symptoms do not identify the condenser by themselves. Leaks can occur at lines, seals, service ports, the compressor, evaporator, receiver/drier, or condenser, while air-door, sensor, fan, electrical, or control faults can also reduce cooling. Low refrigerant pressure can cause the control system to inhibit compressor operation. The prior card incorrectly treated the front-mounted condenser as the leading universal cause and mixed generations, engines, integrated components, and part numbers without a complete leak diagnosis.
Common Symptoms
A/C blows warm or only slightly cool air
Cooling returns after a recharge and then fades
Low system pressure prevents compressor operation
Dye, oily residue, detector response, or physical damage is found at the condenser
How to Fix
Have qualified A/C service personnel identify the refrigerant on the underhood label, recover and measure the existing charge with compatible equipment, scan the HVAC/powertrain systems as applicable, and perform pressure and cooling-performance checks. Leak-test the entire system with approved fluorescent dye and/or an electronic detector and inspect all connections, lines, ports, compressor, evaporator drain, receiver/drier, and both faces of the condenser. Replace a condenser only when dye, detector response, oily residue, or visible physical damage confirms that it leaks. Use the exact VIN, platform, engine, drivetrain/cooler configuration, port layout, dimensions, and current supersession to select the assembly; 2021 WL/Grand Cherokee L applications must not be matched to a WK condenser. Replace disturbed seals and any separately required drier according to the exact service information, add only the specified oil amount, evacuate the system, verify vacuum integrity, and charge the exact label quantity. Do not use stop-leak or mix refrigerants or service equipment.
Owner tips & cautions
WarningDo not buy a condenser because the A/C is warm or because a recharge leaked down. The exact leak location and any separate control or air-door fault must be proven first.
WarningAvoid stop-leak products. FCA warns they can contaminate the system and damage recovery, evacuation, and charging equipment.
On the 2005-2021 Jeep Grand Cherokee, grand Cherokees develop heater-core problems from two directions: internal clogging (residual casting sand/scale restricting the fine tubes, producing weak or no heat) and leaks at the core or its plastic firewall inlet/outlet elbows (producing a sweet coolant smell, a greasy fog film on the inside of the windshield, and a damp passenger-side floor). A leaking core also slowly loses coolant and can lead to overheating. The repair is labor-intensive because the dash must be removed to reach the core buried in the HVAC housing, so misdiagnosis is costly.
Confirm the diagnosis: sweet smell + foggy windshield + wet passenger carpet = leaking core; cold-only output with good coolant flow points to a clogged core (attempt a back-flush first). Pressure-test the cooling system and inspect the plastic heater pipes/elbows at the firewall, which can be replaced separately if that's the leak point. If the core itself leaks or is clogged, replace the heater core (dash-out labor). Refill and bleed the cooling system afterward and verify heat and no coolant loss.

On the 2011-2021 Jeep Grand Cherokee, on WK2 Grand Cherokees the sunroof/panoramic roof drain tubes kink, slip off, or clog with debris and slime at the lower reducer fittings. When the drains back up, water overflows the roof track and runs down the A-pillars into the headliner and floor, soaking carpet and risking mold and electrical module corrosion. The lower hose hidden near the driver kick panel is a frequent partial-clog point.
Water dripping from the headliner or A-pillars after rain or a car wash
Wet front or rear floor carpet
Musty / mildew smell inside the cabin
Water pooling in footwells
Fogged windows or intermittent electrical faults from moisture
How to Fix
Clear the front and rear drain tubes with low-pressure compressed air or a flexible line (avoid high pressure, which can pop the tube off the roof). Re-seat or replace cracked/disconnected tubes; some require partial headliner removal. Dry the carpet/underlayment fully to prevent mold and protect floor electronics.
On the 2011-2021 Jeep Grand Cherokee, water found in a WK2 Grand Cherokee cargo well, under the cargo floor, or near a rear pillar is a symptom, not proof that one grommet, weatherstrip, lamp gasket, antenna seal, or roof seam has failed. The factory water-leak procedure warns that water can travel through body cavities and appear far from the true entry point. The old card's shopping list could therefore send an owner to four unrelated products before the leak location was established.
Common Symptoms
Standing water or dampness in the rear cargo area
Wet cargo carpet or insulation after rain or washing
Water track near a rear pillar, liftgate opening, or cargo trim
Musty odor or interior condensation
How to Fix
Dry the accessible area enough to see a new water track, protect affected electrical connectors and modules, and reproduce the conditions under which the leak occurs. Follow the factory water-leak procedure: visually inspect plugs, drains, alignment, seams, seals, and grommets; test one region at a time with an appropriate low-pressure stream or fan spray; remove trim only as needed for safe visual access; and trace the highest fresh water track to its actual entry point. Repair, reseat, or replace only the confirmed failed seal, seam, fastener, drain, weatherstrip, glass bond, lamp seal, or wiring pass-through using the current factory procedure and specified material. Dry wet insulation, inspect exposed terminals for corrosion, and repeat the water test before closing the trim. Do not smear generic RTV across several unconfirmed paths.
Owner tips & cautions
WarningThe puddle location may not be the entry location. Do not buy a grommet, weatherstrip, sealant, or lamp seal until a controlled water test identifies the source.
TipPhotograph the first fresh water track during the test and retest after the repair before reinstalling all wet trim and insulation.

On the 2011-2023 Jeep Grand Cherokee, owners of panoramic-sunroof-equipped Grand Cherokees (WK2 and 5th-gen WL) report the glass panel spontaneously shattering or 'exploding' with a loud pop while driving on clear days, with no impact. NHTSA complaints and forum reports describe the tempered panel bursting outward/inward, sometimes at low mileage. Suspected causes include factory pre-stress in the tempered glass, ceramic-frit edge stress, thermal cycling, and frame/mechanism stress on the panel. Beyond the repair cost, flying glass and startle-factor while driving make it a safety concern; owners frequently struggle to get warranty coverage and pay out of pocket.
Spider-cracked or collapsed panoramic panel with no impact
Glass falling into cabin (often caught by sunshade)
Occurs at speed on clear days
Wind noise/water entry after the panel breaks
Sudden startle event while driving
How to Fix
There is no preventive repair — the panel must be replaced with new tempered glass (dealer or auto-glass shop), and owners should verify the sunroof frame/track and drains are correct so the replacement isn't re-stressed. Document the event and file an NHTSA complaint (helps trigger any future investigation/coverage) and check comprehensive insurance, which often covers glass with low/no deductible. Retain any FCA/Stellantis goodwill-assistance option for low-mileage vehicles.

On the 2011-2021 Jeep Grand Cherokee, p0442 (small EVAP leak, roughly a 0.020–0.040 inch pinhole) is very common on the WK2 Grand Cherokee. The two dominant causes are a degraded gas cap rubber seal and, specific to this platform, a failed Evaporative System Integrity Module (ESIM) mounted in the rear driver-side wheel well. The ESIM is a well-documented WK2 failure point and often fails before other EVAP components; it is known to pass a smoke test yet still set the code because its internal switch fails to report the correct state to the PCM. A vapor canister purge valve stuck slightly open is a secondary cause. There are typically no drivability symptoms beyond the check engine light, and the code can be intermittent (may clear after a few good drive cycles once the cap is tightened).
Start with a new OEM Mopar gas cap and confirm it clicks/seals; clear the code and drive several cycles. If it returns, replace the ESIM in the rear driver-side wheel well (accessed behind the fender liner, on the charcoal canister). If still present, smoke-test the EVAP system to find hose/purge-valve/canister leaks.
