    GM recalled 2021 Cadillac XT5 and XT6 and GMC Acadia vehicles on which the fuel supply line may not have been fully seated and locked at the quick-connect fitting during assembly. An unseated line can loosen or separate under fuel system pressure and vibration, spraying gasoline in the engine bay or under the vehicle, creating a fire hazard and a potential stall from loss of fuel pressure.

    This issue also affects: Cadillac XT4, Cadillac XT6, Cadillac XTS

    Common Symptoms

    • Strong raw gasoline smell around the vehicle
    • Visible fuel wetness or drips near the fuel line routing
    • Hard starting or stalling from low fuel pressure
    • Fuel odor entering the cabin

    How to Fix

    Verify the VIN against NHTSA campaign 21V422000; dealers inspect and replace the fuel supply lines at no charge. Owner notification letters went out July 1, 2021. If you smell raw fuel, do not drive the vehicle - have it inspected, because an unseated quick-connect can go from a seep to a full separation without warning.

    GM safety recall N202314760 covers certain 2020 XT5 vehicles equipped with AWD RPO F48 and F46. Burrs inside the fuel-pump mixing tube can prevent transfer from the secondary side of the tank, obstruct fuel flow at low fuel level and cause an unexpected engine stall.

    Common Symptoms

    • Unexpected engine stall at low fuel level
    • Loss of fuel transfer from the secondary side of the tank

    How to Fix

    Check the VIN for an open NHTSA 20V639 / GM N202314760 campaign. If open, arrange the dealer fuel-pump module replacement at no charge. Do not buy the recall pump from a commerce link; GM directs use of the VIN and electronic parts catalog for the exact module.

    A safety recall covers certain 2022 Cadillac XT5 models for a fuel tank rollover valve that may not provide a proper seal in the event of a rollover crash. The valve sits in the fuel tank assembly and is meant to close the tank off when the vehicle is inverted or on its side. GM found that it may be dislodged or missing on affected vehicles, so the seal it is supposed to make will not happen. The result, per NHTSA's consequence statement, is a fuel leak during a rollover crash and an increased fire risk. Owners should treat this as a latent safety defect rather than a fault to watch for: nothing about how the XT5 starts, drives, idles or fills up will reveal it, and it matters only in the one crash scenario the valve exists to handle. That makes a VIN check the only practical way to know where a given XT5 stands.

    How to Fix

    Dealers perform the fix at no cost under recall 22V446000 (GM N222366070): they inspect the fuel tank and replace the fuel tank shell if the rollover valve is found dislodged or missing. GM mailed owner notification letters on July 27, 2022. If you bought the XT5 used or are unsure the work was ever done, run the VIN at nhtsa.gov/recalls, which shows any recall still open on the vehicle, then book the inspection with a Cadillac dealer.

    GM bulletin 20-NA-136 (May 2024) gives a diagnostic and repair strategy for 9T65 nine-speed automatics (RPO M3W/M3V) in 2021-2024 XT5 and related GM crossovers that set transmission DTCs with less than 12,000 miles on the odometer. It points technicians to PIP5974 for a clutch snap-ring pop-out that can set P0746/P0747. Depending on which solenoid-related codes reproduce on a road test and on fluid condition, the bulletin calls for replacing the solenoid body and/or control valve body, and for removing the transmission to inspect the clutches when the fluid is dark and burnt. The earlier replacement pilot program has ended.

    This issue also affects: Buick Regal, Cadillac CT5, Chevrolet Silverado 1500

    Common Symptoms

    • Check engine light with transmission DTCs (such as P0746/P0747) at low mileage
    • Harsh, soft or delayed shifts or slipping

    How to Fix

    Have a qualified technician confirm the transmission RPO and current GM guidance before choosing a repair. Bulletin 20-NA-136 calls for recording all DTCs, checking fluid level/condition and line pressure, and a road test; its replacement pilot has ended, so it does not mandate a replacement transmission. P0747 can also occur at shutdown without an internal mechanical fault. Repair scope and warranty eligibility must be established for the diagnosed condition. Ask Cadillac to check the VIN for the separate 23V172 sun-gear recall.

    Recall 23V172 / GM N222389310 covers selected 2022–2023 XT5 vehicles with a dimensionally incorrect transmission sun gear. The June 2023 filing identifies 1,023 XT5s built April 1–December 19, 2022; the 2.0L four-cylinder is excluded. A driver-side half-shaft can disengage, causing loss of propulsion or mechanical Park and a crash or roll-away risk. Grinding or clicking from the front may occur. Vehicle eligibility is determined from manufacturing and transmission records, not the model year alone.

    This issue also affects: Cadillac CT6, Cadillac XT6

    Common Symptoms

    • Sudden loss of drive - engine revs but vehicle does not move
    • Vehicle rolls when shifted to Park
    • Grinding or clicking noise from the front of the vehicle
    • Loss of motive power while driving

    How to Fix

    Have a Cadillac dealer confirm VIN eligibility and repair history for N222389310 and schedule the no-charge transmission sun-gear replacement. GM's owner letter estimates approximately 10–12 hours of repair work depending on model, with additional time possible for scheduling. A prior repair for the condition does not necessarily replace the recall work. Set the parking brake whenever parked, including while awaiting the completed remedy.

    The Cadillac XT5 uses an 8-speed (2017-2019) or 9-speed (2020+) automatic transmission. The 8-speed shares the torque converter shudder issue with other GM 8-speed vehicles. The 9-speed (GM 9T50/9T65) can have harsh shifts, delayed engagement, and shift hunting. Both transmissions have been subject to multiple software calibration updates from GM. The 9-speed is particularly sensitive to fluid condition and requires proper Dexron HP fluid.

    This issue also affects: Buick Encore GX, Buick Regal, Cadillac DeVille

    Common Symptoms

    • Shudder at light throttle between 25-50 mph (8-speed)
    • Harsh or clunky 1-2 shift
    • Delayed engagement from Park to Drive
    • Transmission hunting between gears on hills (9-speed)
    • Hesitation on acceleration from stop

    How to Fix

    First step is a TCM software update at the dealer - multiple calibrations have been released. For 8-speed shudder, a fluid exchange with Mobil 1 LV ATF HP may resolve it. The 9-speed typically responds well to software updates. Persistent issues may require torque converter replacement (8-speed) or valve body replacement (9-speed).

    GM PIP5608F covers 2020-2021 XT5 vehicles with 9-speed transmissions RPO M3G or M3W when torque-converter clutch shudder occurs on re-apply after a shift at 40 mph or below. GM identifies possible excessive assembly lubricant in the fluid and requires confirmation with TCC slip data or the scan-tool command test.

    Common Symptoms

    • Low-speed shudder on TCC re-apply after a shift
    • Concern occurs at 40 mph or below
    • Concern changes when TCC is commanded on

    How to Fix

    Have a qualified transmission technician verify RPO M3G or M3W and confirm the event is TCC shudder using slip-speed data or the commanded-on test. If the bulletin criteria are met, follow the GM DEXRON VI drain-and-fill procedure and drive at least 200 miles before judging the repair. Do not use a universal additive or flush kit. The exact ShowMeTheParts lookup returned no transmission-fluid candidate.

    Multiple XT5 owners report the fixed front panel or the sliding panel of the panoramic UltraView sunroof exploding without any impact, typically while driving at 55-70 mph. Owners describe a gunshot-like bang followed by tempered glass falling into the cabin. The failure pattern is consistent with edge stress in the tempered laminate combined with body flex in the large roof opening, and it is reported across 2017-2019 in NHTSA filings with no recall issued.

    Common Symptoms

    • Loud bang or explosion sound from the roof while driving
    • Tempered glass fragments falling into the cabin
    • Sunroof shade torn or bulging
    • Wind noise and water entry after the event

    How to Fix

    The panel is not repairable - the glass assembly must be replaced, and the roof track and drains should be inspected for debris and for a bent or binding sliding panel that could be preloading the glass. Some owners have obtained goodwill assistance from Cadillac; comprehensive auto insurance with glass coverage typically covers it. Aftermarket glass is significantly cheaper than the OEM assembly.

    Certain 2024 XT5 vehicles (along with some 2024 XT6 and 2023 GMC Acadia) may have been assembled without the proper urethane sealant required to bond the windshield to the vehicle body. A windshield that is not properly bonded may detach during a crash, increasing the risk of injury. The campaign is small, so check the VIN; affected cars may show no symptom at all.

    Common Symptoms

    • No owner-visible symptom identified in the recall filing; check the VIN

    How to Fix

    Free recall remedy under NHTSA campaign 23V681000 (GM N232419690). The dealer inspects the windshield and properly applies primer and urethane; if the windshield is damaged, it is replaced. Arrange the work through the Cadillac dealer. GM's recall procedure permits the dealer to sublet resealing or replacement to a local glass repair facility, which must follow GM's procedure.

    The power liftgate struts lose their charge and fail to hold the liftgate open, causing it to slowly close or fall. The motorized struts can also operate erratically, stopping mid-travel or failing to open fully. In cold weather, the struts may not have enough force to lift the gate at all.

    Common Symptoms

    • Liftgate will not stay open
    • Liftgate closes slowly on its own
    • Liftgate stops mid-travel
    • Liftgate will not open in cold weather
    • Warning beep during liftgate operation

    How to Fix

    Replace both power liftgate struts as a pair. Use OEM struts for proper fit with the power liftgate system. After replacement, the liftgate height setting may need to be reprogrammed. If the liftgate motor is also weak, it should be replaced at the same time. Lubricating the hinge points helps reduce strain on the struts.

    A limited build of 2024 XT5 vehicles received a driver's front air bag module whose cushion may tear when the bag deploys. A torn cushion can degrade air bag performance in a crash, increasing the risk of injury. GM attributes the condition to a supplier airbag-cushion design change during a brief production window (February 2024; 74 vehicles). The recall filing identifies no owner warning, which is what makes VIN-checking this campaign worthwhile even on a car with no symptoms.

    Common Symptoms

    • No symptoms - the recall filing identifies no owner warning

    How to Fix

    Free recall remedy under NHTSA campaign 24V311000 (GM N232439241). Dealers replace the driver's front air bag module with an updated design at no cost. Check the VIN at nhtsa.gov/recalls; the affected population is a narrow production range within the 2024 model year, so most 2024 XT5s are not included. The recall filing identifies no owner warning, so a normal-looking air bag system does not rule the vehicle out.

    GM recalled certain 2020 Cadillac XT5 crossovers because their Continental tires were cured for too long during manufacture. The recall record gives two failure paths for an over-cured tire: a break in the sidewall that vents the air suddenly, or a belt edge separation that lets the tread and belt come off. Either can cause the driver to lose control of the vehicle and increase the risk of a crash. The campaign is not limited to factory-fitted tires — it also covers Continental tires sold to the aftermarket for a range of 2018-2021 vehicles, which is worth knowing if the XT5 has been re-shod since new.

    Common Symptoms

    • Rapid, sudden air loss from a tire
    • Sidewall break
    • Belt/tread separation
    • Loss of vehicle control

    How to Fix

    The remedy is free at a Cadillac dealer: the dealer inspects the tires and replaces any that fall within the recalled production. Owner letters went out beginning March 22, 2021. If you bought the XT5 used, or aren't sure the work was done, check the VIN at nhtsa.gov/recalls or call Cadillac customer service at 1-800-458-8006 and cite GM recall N212329050.

    On 2020-2021 XT5, XT6 and GMC Acadia models optioned with Surround Vision, the coaxial cable connector feeding the rear camera may be improperly crimped. The connection degrades and the rearview image goes black, freezes, or fails to appear when reverse is selected. Separately, non-recall XT5 owners across 2020-2023 report the backup camera taking 15-20 seconds to switch out of night mode and grid lines being nearly invisible in bright sun - a display-calibration complaint distinct from the crimp defect.

    Common Symptoms

    • Black screen when reverse is selected
    • Rearview image freezes or flickers
    • Camera takes 15-20 seconds to brighten after dark-to-light transition
    • Faint or invisible guideline overlay
    • Surround Vision top-down view missing panels

    How to Fix

    Check the VIN against NHTSA campaign 22V709000 (GM recall) and have the dealer replace the coaxial cable at no charge. For non-recall cars with a slow or dim image, update the infotainment and video processing module software, clean the camera lens and its washer nozzle, and verify the connector at the liftgate harness pass-through, which flexes every time the power liftgate cycles.

    GM bulletin 21-NA-183 covers 2017-2022 XT5 (up to a 2022 VIN breakpoint) along with related GM crossovers. Customers may report intermittently inoperative door locks, instrument-panel lamps illuminating, immobilizer concerns, or unwanted horn or hazard-flasher operation, and technicians may find BCM codes B3125, B3130, B3135, B3979 or B3980 along with various U codes. GM attributes the condition to possible water intrusion to the Body Control Module from the HVAC drain hose leaking at its connection to the HVAC module.

    Common Symptoms

    • Door locks intermittently inoperative
    • Instrument-panel lamps illuminate while driving
    • Immobilizer concerns
    • Unwanted horn or hazard-flasher operation
    • BCM codes B3125, B3130, B3135, B3979 or B3980 with various U codes

    How to Fix

    Have the technician confirm applicability of GM bulletin 21-NA-183, including its 2022 VIN breakpoint, and inspect the HVAC drain connection, hose routing and blockage. Follow the bulletin's reseating and tie-strap procedure. Inspect the BCM and connectors for water damage and corrosion using the specified handling precautions; replace the BCM only as necessary after inspection, with the correct VIN-selected part and programming procedure. Repair damaged connectors as diagnosed, rather than assuming every pigtail needs replacement. Correct and verify the leak before returning the vehicle to service.

    Certain 2023-2025 XT5 (and 2024-2025 XT6) crossovers have an instrument-cluster software fault where the panel does not illuminate the indicator when the hazard warning lights, high beams or turn signals are activated. With no telltale, the driver has no in-car feedback that those functions are on and can leave hazards flashing, high beams on or a turn signal running, which can confuse other road users. NHTSA lists about 6,942 vehicles in the campaign across XT5 and XT6; VIN eligibility determines coverage. The remedy is a cluster software update, so it can appear on a low-mileage vehicle.

    Common Symptoms

    • Green turn-signal arrows do not flash on the cluster
    • High-beam blue telltale does not illuminate
    • Hazard warning triangle indicator stays dark
    • Driver leaves hazards or high beams on unknowingly

    How to Fix

    Free recall remedy under NHTSA campaign 24V459 (GM number N242447940). The dealer updates the instrument cluster software at no charge; for certain vehicles the remedy requires replacing the instrument cluster assembly. For vehicles assigned to N242447941, GM requires the radio to be programmed before the cluster to avoid cluster damage. Owner notification letters were mailed 13 August 2024. If the telltales still do not light after the recall work, return to the dealer.

    A faulty park-position switch inside the electronic shifter assembly intermittently fails to signal that the vehicle is in Park. This produces a persistent 'Shift to Park' message on the driver information center even when the lever is physically in Park, and the vehicle may refuse to fully power down, staying in accessory mode and draining the 12V battery overnight. Owners report shifter codes such as P07BE and P26C8. GM addressed the concern with TSB 19-NA-206. This is an electronic-shifter/electrical failure, separate from internal transmission shudder/harsh-shift issues.

    This issue also affects: Cadillac CT6, Cadillac XT6

    Common Symptoms

    • 'Shift to Park' message stays on with lever already in Park
    • Vehicle will not fully shut off / stays in accessory mode
    • Dead 12V battery overnight from failure to power down
    • Shifter error codes P07BE / P26C8
    • Intermittent refusal to shift out of Park

    How to Fix

    Per GM TSB 19-NA-206 the repair is often installing an in-line jumper harness (P/N 84733196) at the shifter connector; where that does not resolve it, the shifter assembly is replaced. Replacement requires removing the center console trim and generally needs no special programming. Pressing the Park button squarely in the center can be a temporary workaround for the dual-sensor design.

    The XT5 V6 models use the GM 3.6L V6 (LGX) which has improved timing chains over earlier versions but is not immune to timing chain stretch at higher mileage. The LGX is better than the earlier LFX but still uses three timing chains with plastic guides. Issues typically appear later (100,000-150,000 miles) compared to earlier 3.6L variants. The 2020+ XT5 2.0T models use a different engine (LSY) and are not affected by this issue.

    This issue also affects: Buick Cascada, Buick Enclave, Buick Encore

    Common Symptoms

    • Check engine light with timing correlation codes
    • Rattling on cold start
    • Rough idle or misfires at high mileage
    • Reduced engine power warning

    How to Fix

    Same timing chain replacement as SRX/CTS 3.6L. Cloyes 9-0753S kit, replace water pump simultaneously. The LGX timing chain typically lasts longer than the LFX, so preventive replacement at 100,000+ miles is recommended rather than the 80,000-mile interval for earlier engines.

    GM 21-NA-240, revised January 2025, addresses oil leaks on LSY-equipped vehicles including the XT5. An improper amount of sealant at the cam carrier can be a cause. Oil from this area can appear to originate at the camshaft carrier, front cover, lower oil pan or timing-chain upper cover. The bulletin does not establish the source of every leak and does not cover the LGX V6.

    This issue also affects: Cadillac XT6

    Common Symptoms

    • Engine oil leakage
    • Oil visible around the camshaft carrier, front cover, lower oil pan or upper timing-chain cover

    How to Fix

    A technician should clean residual oil and use the bulletin's dye/trace-powder process to identify the source. If the leak is isolated to the cam-carrier T-joint, GM directs resealing under the Camshaft Carrier Replacement service procedure. If not, continue diagnosis and repair the actual source. Obtain a vehicle-specific estimate and coverage decision; do not authorize multiple reseals solely because oil is visible at several joints.

    General Motors recalled early-production 2017 Cadillac XT5 and GMC Acadia vehicles for front brake calipers that may have a defective piston seal. The seal can allow hydraulic brake fluid to leak past the piston, reducing braking effectiveness and, if it goes unnoticed, dropping master cylinder reserve to the point of a soft or long pedal. This is a manufacturing defect in a specific caliper lot, not a wear item, and it is separate from the more familiar XT5 rotor and pad complaints.

    Common Symptoms

    • Brake fluid level dropping with no visible line leak
    • Soft or gradually lengthening brake pedal
    • Brake fluid wetness on the inboard side of a front caliper or on the pads
    • Brake warning light
    • Longer stopping distances

    How to Fix

    Check the VIN against NHTSA campaign 16V802000; affected vehicles get the front brake caliper assemblies inspected and replaced free of charge and the system bled. If you have an early 2017 build with a slowly dropping brake fluid level and no visible external line leak, pull the front wheels and inspect the inboard face of each caliper and the pad backing plates for fluid wetness before chasing a master cylinder.

    The front brake rotors warp prematurely, causing steering wheel vibration and brake pedal pulsation during moderate to hard braking. The issue is attributed to the heavy vehicle weight combined with rotors that are borderline in thickness for the application. Aggressive braking or mountain driving accelerates warping.

    Common Symptoms

    • Steering wheel vibration when braking
    • Brake pedal pulsation
    • Vibration worse at highway speed braking
    • Uneven pad wear

    How to Fix

    Replace the front brake rotors with quality aftermarket rotors that meet or exceed OEM thickness. Bed in the new rotors and pads properly with a series of moderate stops. Avoid hard braking followed by holding the brake (which creates hot spots). Upgrading to slotted rotors can help manage heat better.

    2017 XT5 models with AWD (RPO F48) use an electronically controlled twin-clutch rear drive system. On affected vehicles the rear differential carrier can apply higher than commanded torque as mileage accumulates. Applying that torque on a low-traction surface during a low-speed wide-open-throttle launch can fracture the rear propeller shaft. GM's service update describes a loud pop followed by a grinding noise and significant vibration. This is specific to the F48 AWD hardware and its control calibration; front-drive XT5s are not affected, and it is a distinct failure from ordinary rear-diff clutch-fluid service.

    Common Symptoms

    • Loud pop from under the vehicle during hard low-speed acceleration
    • Grinding noise after the pop
    • Significant driveline vibration

    How to Fix

    GM Service Update 17109 applies to certain 2017 XT5 AWD vehicles with RPO F48. The specified remedy is dealer reprogramming of the rear differential clutch control module; no parts are required for the update. This was a service update, not a safety recall, and the bulletin expires at the end of the vehicle's New Vehicle Limited Warranty. Ask a dealer to verify VIN involvement, completion history and any current coverage before assuming the work is free. A fractured shaft or severe vibration requires separate inspection and repair; do not continue driving with significant driveline vibration.

    This is an assembly-process recall rather than a design defect. On certain 2022 Cadillac XT5 crossovers, the left-rear suspension toe link may have been tightened improperly, so the fastener that secures it can be loose — or, per the remedy language, missing. GM warns that a loose toe link can separate, and that separation causes a loss of vehicle control with an increased risk of a crash, which is why this one carries a high severity rather than being a wait-until-your-next-service item. NHTSA filed it as campaign 22V427000 under SUSPENSION:REAR; GM's internal number is N222364330. The 2022 Cadillac XT6 and 2022 GMC Acadia fall under the same campaign. Units affected were not stated in the NHTSA record.

    Common Symptoms

    • Loose or missing left-rear toe link fastener
    • Toe link separation
    • Loss of vehicle control

    How to Fix

    Free of charge at a Cadillac dealer: they inspect the left-rear suspension and replace the fastener if it is loose or missing. Owner letters were mailed July 11, 2022. Because the inspection is quick and the failure mode is a loss of control, do not defer it — verify your VIN at nhtsa.gov/recalls to confirm whether your XT5 is included and whether the repair has already been done, or call Cadillac customer service at 1-800-458-8006 quoting N222364330.

    The engine thermostat on the 3.6L LGX V6 commonly sticks in the open position, so the engine never reaches its target operating temperature. The ECM sets P0128 and, because the electric power steering assist and A/C compressor operation are both load-managed off engine/coolant state, the driver gets a 'Steering Assist is Reduced - Drive With Care' message and loses A/C, sometimes with noticeably heavier steering effort. Owners across 2017-2019 report this as the single most-repeated XT5 fault in NHTSA filings, often with the replacement thermostat housing on national backorder. It is a cooling-system fault masquerading as a steering and HVAC fault, which is why many owners are first quoted power-steering diagnostics.

    This issue also affects: Buick Encore GX, Cadillac Allante, Cadillac Catera

    Common Symptoms

    • 'Steering Assist is Reduced, Drive With Care' message on the DIC
    • Check engine light with P0128
    • Air conditioning stops blowing cold / compressor disabled
    • Engine temperature gauge reads low or takes a very long time to warm up
    • Heater blows lukewarm in cold weather
    • Steering effort feels heavier than normal

    How to Fix

    Replace the thermostat/water outlet housing assembly (the thermostat is integral to the plastic housing on the LGX - it is not serviced separately) and refill/bleed the cooling system with DEX-COOL. Clear P0128, then verify coolant temperature reaches roughly 195-215F on a scan tool before condemning the steering rack or A/C compressor. Do not replace the power steering rack for this message until engine coolant temperature has been verified.
