NHTSA recall 23V-526 covers certain model-year 2023 Hyundai Tucson vehicles. The Idle Stop & Go transmission electric oil-pump controller may contain a printed circuit board damaged during manufacturing. A damaged capacitor can affect operation and cause heat damage to the pump circuit board, connector and wiring harness, increasing the risk of a vehicle fire and potentially disrupting controller-area-network communication. Warning signs can include underbody smoke, a burning or melting odor, or warning-lamp illumination.
Common Symptoms
Smoke from the vehicle underbody
Burning or melting odor
Malfunction Indicator Lamp or other warning lamps illuminate
How to Fix
Check the VIN for NHTSA recall 23V-526. Until the remedy is completed, Hyundai recommends parking outside and away from structures. A Hyundai dealer will inspect and replace the electric oil pump and front wiring harness if necessary, at no charge.
NHTSA recall 25V-893 covers certain model-year 2022-2024 Hyundai Tucson vehicles equipped with an optional OEM trailer wiring harness installed as a port-installed or dealer-installed option. The harness control module was installed in a location susceptible to water ingress and has insufficient sealing. Water inside the module can make trailer or vehicle stop lamps inoperative or, in rare cases, cause a short that can overheat, melt or ignite, increasing crash and fire risk. Intermittent or inoperative parking, turn-signal, or stop lamps on the vehicle or trailer may provide warning.
Common Symptoms
Intermittent or inoperative vehicle or trailer parking lamps
Intermittent or inoperative vehicle or trailer turn-signal lamps
Intermittent or inoperative vehicle or trailer stop lamps
How to Fix
Check the VIN for NHTSA recall 25V-893. Until the remedy is completed, Hyundai recommends parking outside and away from structures. When parts are available, a Hyundai dealer will replace the trailer wiring harness at no charge; the replacement control module has improved sealing to prevent water intrusion.
Hyundai recalled certain 2025 Tucson and Santa Cruz vehicles under NHTSA campaign 24V877000 because the console extension wiring assembly may be routed improperly. The misrouted harness defeats the brake-transmission shift interlock, allowing the transmission to be shifted out of Park without the brake pedal being applied. A vehicle that can leave Park without brake application can roll away unattended — the classic failure mode is a driver reaching in to move the shifter, or a child or object bumping it, with the vehicle then rolling free. Hyundai's interim guidance to owners was explicit and unusual: use the parking brake every time you park until the repair is done. Notification letters went out December 17, 2024. This is a build/routing defect rather than a software fault, so it cannot be fixed over the air.
Common Symptoms
Transmission shifts out of Park without pressing the brake pedal
Vehicle rolls away after being parked
Brake-transmission shift interlock does not engage
How to Fix
Check your VIN against NHTSA campaign 24V877000 and schedule the free dealer repair, which reroutes the console extension wiring assembly. Until the recall is performed, apply the parking brake every single time you park, without exception, including on surfaces that appear level — this is Hyundai's own stated interim remedy. You can test whether your vehicle exhibits the defect safely: with the parking brake firmly set, the engine running and your foot off the brake pedal, attempt to move the shifter out of Park. On a correct vehicle the interlock prevents it. If the shifter moves, the interlock is defeated on your car and the recall repair is urgent rather than routine. Do not leave children unattended in the vehicle at any time before the repair.
The dominant electrical failure on the current Tucson is a software fault that blanks the digital instrument cluster, and on equipped cars the head-up display and center touchscreen along with it. Hyundai has recalled the vehicle for it twice: NHTSA campaign 26V047000 (March 2026) covered 2025-2026 Tucson, Tucson Hybrid and Tucson PHEV among a broad list of Hyundai models, and campaign 26V400000 (August 2026) recalled roughly 96,000 additional 2025-2026 Tucson, Tucson Hybrid and Tucson PHEV vehicles for the same defect — meaning the first software remedy did not fully resolve it. Both campaigns cite noncompliance with FMVSS 101, 'Controls and Displays,' because the driver loses the speedometer and warning telltales. Fifty-one NHTSA complaints on the 2025 Tucson carry an ELECTRICAL SYSTEM component. Owners describe the cluster showing a black screen with 'NO SIGNAL' for minutes at a time (ODI 11749421), dropping out for three seconds every one to two minutes and taking the side cameras with it (ODI 11729572), a daily and progressively worsening total blackout of cluster and infotainment (ODI 11731497), and one car diagnosed with a rear-view camera display failure behind the blank cluster (ODI 11715488). Several reports pair the blackout with the vehicle stalling or failing to start.
Common Symptoms
Digital instrument cluster goes black displaying 'NO SIGNAL'
Head-up display flickers or turns off, sometimes over bumps
Center touchscreen glitches, strobes, freezes or blacks out
Loss of speedometer and all warning telltales while driving
Backup and side camera views unavailable
All dashboard warning lights illuminate at once
How to Fix
Check your VIN against both NHTSA campaigns 26V047000 and 26V400000 — having had the first update performed does not mean you are covered for the second, and the second campaign exists precisely because the first remedy was insufficient. The remedy is a free instrument panel display software update delivered over the air or by a dealer; confirm at the dealer which software level is installed rather than assuming the OTA landed. If the blackout persists after the current update, insist the dealer stop treating it as a software item and inspect the cluster's harness connector and grounds, since several complaints correlate the dropout with bumps and rough pavement (ODI 11751042), which is a connector symptom rather than a software one. Where the failure coincides with stalling or a no-start, have the 12V battery and its terminals load-tested as well. Do not drive without a speedometer any longer than necessary; the fault is intermittent and can strand you without warning telltales.
The JM-generation Tucson's stop lamp switch develops a high-resistance or open contact. Because the switch feeds far more than the brake lamps, a failure cascades: brake lights stop working, the brake-transmission shift interlock will not release so the vehicle cannot be shifted out of Park, the push-button start (where fitted) may not respond, the Electronic Stability Control can be disabled, and cruise control may fail to disengage on brake application. Hyundai recalled the switch twice - first in 2009 (campaign 092) and again in April 2013, when 1,059,824 model year 2007-2009 Accent and Tucson vehicles were called back, with a further 652,512 vehicles added that September. The failure is intermittent and often presents first as an inability to shift out of Park in a parking lot.
Common Symptoms
Brake lights do not illuminate, or stay on continuously
Cannot shift out of Park with the brake pedal pressed
Cruise control will not engage or will not cancel on braking
ESC / traction control warning light on
Intermittent no-start on push-button-start vehicles
How to Fix
Free recall remedy: dealers replace the stop lamp switch under NHTSA 09V122000 and/or 13V113000 (Hyundai campaign 092). Have the VIN checked on the NHTSA recall lookup even on a vehicle bought used - many of these were never redeemed. Outside the recall, the switch is an inexpensive plug-in part behind the brake pedal arm; check switch adjustment and the plunger bumper on the pedal stop at the same time, since a crumbled rubber bumper produces the same symptoms.
On 2019-2021 Tucson, the Mando-supplied ABS hydraulic electronic control unit can short internally and ignite an engine-bay fire while parked or driving. Supplier analysis found soldering flux residue left on the HECU main controller board; heat and humidity let that residue corrode the board and create an electrical short. NHTSA opened the campaign after 12 documented fires (nine in 2019 models, two in 2020, one in 2021). Hyundai issued a park-outside-away-from-structures warning because the module stays powered with the ignition off. A follow-on equipment recall (21E038) covered the Mando modules themselves. This is an ABS/electrical defect and is unrelated to the engine or fuel system.
Common Symptoms
Burning or melting-plastic smell from the engine bay
Smoke from the engine compartment, sometimes with the vehicle parked and off
ABS and/or ESC warning lights illuminated
Fire originating near the ABS module on the driver-side inner fender
Blown HECU fuse
How to Fix
Free recall remedy under Hyundai campaign 195 / NHTSA 20V543000: dealers install a revised HECU fuse in the engine junction block and, on 2019-2021 vehicles, reflash the Electronic Stability Control software so the module cannot draw enough current to ignite. Some vehicles received a full HECU replacement where corrosion was already present. Until the remedy is performed Hyundai instructs owners to park outside and away from structures. Check the VIN on the NHTSA recall lookup - the fix is free regardless of age or mileage.
Tucson Hybrid and Plug-In Hybrid models repeatedly drain their small 12V lithium starter battery, leaving the vehicle unable to power up. The 12V battery is far smaller (around 19 Ah) than the lead-acid AGM used on the gas model, and persistent standby loads (Bluelink cellular connection, module wake cycles) plus a DC-DC converter that will not top off the 12V when the high-voltage pack is low can flatten it in as little as a day or two of sitting. Owners report using the dash-mounted 12V reset button repeatedly. A related BMS software service campaign addresses a 12V over-voltage warning.
Common Symptoms
Dead 12V battery / vehicle will not power on
Repeated need to press the 12V reset button
Battery drains after the car sits 1-2 days
Bluelink / remote features unresponsive
12V battery over-voltage warning message
How to Fix
Use the interior 12V reset button to recover a temporary start; if it will not hold, jump from the underhood positive terminal and a chassis ground, then drive 30+ minutes to recharge. Apply the Battery Management System update under Hyundai Service Campaign 9B4 (DTC P1BB20 12V battery over-voltage). For vehicles parked for extended periods, drive at least 10 miles / 1 hour a few times a month or use a 12V maintainer; persistent drain after the update warrants a parasitic-draw test and 12V battery replacement under warranty.
NHTSA recall 26V-316 covers certain model-year 2025-2026 Hyundai Tucson, Tucson Hybrid and Tucson Plug-in Hybrid vehicles. The front camera software can be overly sensitive to forward-object proximity in certain driving scenarios, causing the Forward Collision-Avoidance Assist system to engage earlier than expected and potentially produce sudden braking. Sudden braking can increase the risk of a rear-end crash from a closely following vehicle.
Common Symptoms
Forward Collision-Avoidance Assist engages earlier than expected
Unexpected sudden braking
How to Fix
Check the VIN for NHTSA recall 26V-316. A Hyundai dealer will update the front camera software at no charge. The revised software is tuned to better align activation timing and distance with driver expectations.
Hyundai recalled certain 2026 Tucson, Tucson Hybrid and Tucson Plug-In Hybrid vehicles — together with 2025 Elantra N and Elantra — under NHTSA campaign 26V254000 because the B-pillar side impact sensors may have been misassembled. These sensors are what tell the airbag control unit that a side impact is occurring and how severe it is; a misassembled sensor reports the crash pulse late, delaying deployment of the side and curtain air bags. In a side impact the occupant reaches the intruding structure within milliseconds, so a delayed deployment can mean the air bag inflates after the occupant has already made contact, providing little or no protection. There is no warning to the driver — the airbag warning lamp does not necessarily illuminate for a mechanically misassembled sensor, so the defect is invisible until a crash. Owner notification letters were mailed June 11, 2026 under Hyundai recall number 299.
Common Symptoms
No driver-observable symptom before a crash
Airbag warning lamp typically not illuminated
Delayed side and curtain air bag deployment in a side impact
How to Fix
Check your VIN against NHTSA campaign 26V254000 and have the free dealer inspection performed; the dealer will inspect and replace the B-pillar impact sensor or sensors as necessary. Treat this as a high-priority appointment rather than something to bundle with the next oil change, because the defect provides no advance symptom and its consequence is realized only in a crash. Do not assume you are unaffected because the airbag warning lamp is off — the lamp monitors electrical continuity, not sensor mounting orientation. If you have had B-pillar or side body repair work done at a non-Hyundai shop, mention it, since sensor mounting and torque are commonly disturbed in collision repair. Keep the completed repair documentation for resale.
Hyundai recalled certain 2025 Tucson vehicles — along with 2025-2026 Santa Cruz, Santa Fe and Santa Fe Hybrid and 2026 Genesis GV70 — under NHTSA campaign 25V809000 because the side curtain air bags may not have been installed properly at the factory. A curtain air bag that is incorrectly routed, incorrectly fastened, or improperly retained along the roof rail will not deploy in the intended path across the side glass, so it may fail to cover the occupant's head in a side impact or rollover. This is an assembly defect distinct from the separate 2026 Tucson B-pillar sensor recall: 25V809000 concerns the physical installation of the curtain module itself, whereas 26V254000 concerns the sensor that triggers deployment. As with the sensor recall, there is no in-service symptom — the airbag readiness lamp does not detect an improperly installed but electrically intact module. Owner notification letters began going out December 29, 2025 under Hyundai recall numbers 289 and 029G.
Common Symptoms
No driver-observable symptom before a crash
Airbag readiness lamp typically not illuminated
Side curtain air bags may not deploy as designed in a side impact or rollover
How to Fix
Check your VIN against NHTSA campaign 25V809000 and have the free repair performed; dealers reinstall the side curtain air bags. Book it promptly rather than deferring, since the defect is undetectable outside a crash. Do not assume a clear airbag warning light means your vehicle is unaffected. If you have had headliner, roof rail, A-pillar or B-pillar trim work performed — including glass replacement or collision repair — flag it to the dealer, because curtain routing is easily disturbed during that work and the correct retention needs verifying regardless of recall status. If you own both a 2025 Tucson and are within the 2026 build range, check for 26V254000 as well; they are separate campaigns with separate remedies and one does not cover the other.
Turn-key Tucsons built without an engine immobilizer can be started by stripping the steering column, exposing the ignition cylinder and turning it with a USB cable or similar metal object - no key code is ever checked. The vulnerability, popularized as the 'Kia Challenge' on TikTok, made these vehicles theftable in under 90 seconds and drove insurers in several markets to refuse or surcharge coverage. It is a design omission, not a wear failure: Tucsons from 2011 through 2022 are in the eligible population, and only lower trims with a mechanical key are affected - push-button-start vehicles already had an immobilizer. A class-action settlement valued at more than $200 million resolved owner claims.
Common Symptoms
Vehicle stolen or broken into with the steering column shroud smashed
Ignition cylinder pried out or damaged
Insurer declines or surcharges comprehensive coverage
No immobilizer indicator in the cluster on turn-key models
How to Fix
Free dealer software upgrade under Hyundai Campaigns 993 and 9A5: the fix extends the alarm sound to one minute and, critically, makes the ignition inoperative unless the key fob is present, so forcing the cylinder no longer starts the engine. Installation takes under an hour. Check eligibility by VIN at hyundaiantitheft.com. For the minority of vehicles the software cannot support, the settlement reimburses the purchase of a steering wheel lock, alarm kit or other anti-theft device. Independent of the software, a visible steering wheel lock remains an effective deterrent because the theft method depends on being quick and unobserved.
The Tucson's Driver Attention Warning system uses a driver-monitoring camera mounted on the steering column to track eye position. Multiple NHTSA complaints on the 2025 Tucson report the camera repeatedly failing to acquire the driver's eyes and issuing false distraction alerts — the coffee-cup 'consider taking a break' icon with repeating chimes — during normal attentive driving. The reported triggers are physical rather than behavioral: wearing sunglasses, wearing prescription glasses, and short driver stature that places the eyes outside the camera's field of view (ODI 11717385, 11661987, 11692787). The safety-relevant consequence is that the false alert cancels Smart Cruise Control. Complaint 11698087 describes cruise shutting off mid-pass on an interstate, requiring the driver to look down and reset the system at exactly the moment attention should be on the road — an inversion of the feature's purpose. Complaint 11692400 confirms the same architecture on the prior 2024 Tucson. Owners report that neither Hyundai nor dealers will disable the sensor.
Common Symptoms
Repeated 'consider taking a break' coffee-cup alerts while fully attentive
False distraction warnings when wearing sunglasses or prescription glasses
Smart Cruise Control cancels itself mid-drive
Alerts more frequent for shorter drivers
Dealer declines to disable the driver-monitoring camera
How to Fix
First rule out an obstructed or dirty lens: the driver-monitoring camera sits on the steering column shroud and is easily blocked by a phone mount, a steering wheel cover, or fingerprints — clean it with a microfiber cloth and confirm nothing sits in its line of sight. Adjust the steering column and seat height so the camera has an unobstructed view of your eyes; short-stature drivers often resolve the false alerts by raising the seat and lowering the column rather than the reverse. If false alerts persist, the setting is in the vehicle's Driver Assistance menu — Driver Attention Warning can be switched off or reduced in sensitivity there, though on some builds turning it off also limits Smart Cruise Control availability, so verify the tradeoff before relying on it. Ask the dealer to check for a driver-monitoring camera software update, since Hyundai has addressed camera-software behavior on this platform by update before. Report persistent false alerts to NHTSA — the complaint volume is what drives a software remedy.
The Theta II GDI engine in 2011-2019 Tucson models is susceptible to connecting rod bearing failure caused by manufacturing debris restricting oil flow. This can lead to catastrophic engine seizure, often without warning. Hyundai issued multiple recalls (19V-601, 20V-150) and extended the engine warranty to 15 years/unlimited miles for original owners.
Common Symptoms
Metallic knocking from engine
Engine stalling without warning
Check engine light with P1326 code
Loss of power while driving
Excessive oil consumption
How to Fix
Check VIN for active recalls at NHTSA.gov. Ensure the Knock Sensor Detection System (KSDS) software update has been installed - this monitors for early signs of bearing failure and can put the engine in limp mode. If engine has seized, Hyundai will replace it under recall. Out-of-warranty replacement runs $4,500-7,500. Use full synthetic 0W-20 oil and change every 5,000 miles.
Owner tips & cautions
TipGet the KSDS software update immediately if not already done - it can detect bearing failure early and prevent catastrophic seizure
WarningIf you hear any knocking noise, stop driving immediately. Continued driving can destroy the engine beyond repair
High ConfidenceVerified3,200 owner reportsLast reported by owners Jan 2025Reviewed Feb 2026
Hyundai recalled certain 2025-2026 Tucson and Santa Fe vehicles under NHTSA campaign 25V549000 because connecting rod bolts in the engine may have been improperly tightened during assembly. Under-torqued rod bolts allow the big-end bearing cap to work loose, which progresses to bearing failure, rod knock, and ultimately a thrown rod that can breach the block. NHTSA's stated consequences are loss of drive power, which raises crash risk, and an oil leak onto hot engine components that raises the risk of an engine compartment fire. The severity of the remedy is the tell: Hyundai is replacing the entire engine rather than inspecting or re-torquing, which indicates the defect cannot be reliably screened for in service. Owner notification letters were mailed October 23, 2025 under Hyundai's internal recall number 281. The campaign names the Tucson and Santa Fe without listing Hybrid or PHEV variants, unlike Hyundai's other Tucson campaigns which name them explicitly — so this affects the conventional 2.5L gasoline powertrain.
Common Symptoms
Deep knocking or rapping from the lower engine that rises with rpm
Sudden loss of drive power
Oil pressure warning light
Oil leak or burning oil smell from the engine bay
Engine seizure
How to Fix
Check your VIN against NHTSA campaign 25V549000 (Hyundai recall 281) and have the free engine replacement performed. Do not wait for symptoms — the failure mode is progressive and the endpoint is a thrown rod. If you hear a deep knocking or rapping from the bottom of the engine that rises with engine speed, or if the oil pressure warning illuminates, stop driving and have the vehicle towed rather than driven to the dealer; continuing to run a knocking rod converts a warranty engine swap into a fire risk. Check the oil level and inspect for leaks or oil on the underbody more often than usual until the remedy is applied. Because engine replacement is a long-lead repair, ask about a loaner when booking. Retain all service records — a documented recall claim protects you if the failure occurs before the appointment.
The naturally-aspirated 2.5L Smartstream G2.5 GDI engine (distinct from the older Theta II 2.0/2.4) suffers from fuel dilution of the engine oil and, in some units, sticking oil-control rings that drive excessive oil consumption. Raw injected fuel washes past the rings into the crankcase, thinning the oil and, where rings stick, owners report burning roughly a quart per ~1,000 miles. Hyundai responded by increasing the factory oil fill capacity, lengthening the oil-level sensor range, and shortening the recommended oil-change interval.
Common Symptoms
Oil level dropping between changes (low-oil light)
Fuel/gasoline smell on the dipstick
Oil level reading above full (dilution)
Rising oil level with thin/diluted oil
Tapping or knock if oil starves under consumption
How to Fix
Perform a documented dealer oil-consumption test if usage exceeds about a quart per 1,000-1,200 miles to qualify for warranty repair (often updated piston/oil-control rings or a short block). Shorten oil changes to roughly 6,000 miles (some markets dropped from 15K to 7.5K), use the correct 0W-20/0W-30 full synthetic per the latest spec, and check for an oily fuel smell at the dipstick indicating dilution. Avoid extended idling and very short trips that worsen dilution; install any applicable engine/ECM updates.
The 7-speed dual-clutch transmission (DCT) paired with the 1.6L turbo engine in Tucson models suffers from shuddering during low-speed maneuvers, hesitation from a stop, and jerky shifts. The dry clutch design is prone to premature wear. Hyundai extended the DCT warranty to 10 years/100,000 miles under a settlement.
Common Symptoms
Shuddering at low speed (1st-2nd gear)
Hesitation when accelerating from stop
Jerky gear changes
Transmission warning light
RPM flaring between shifts
How to Fix
Check if vehicle is covered under Hyundai DCT warranty extension (10yr/100k miles). A TCM software update can improve shift quality. If clutch is worn, the dual-clutch assembly replacement is needed (Hyundai part 41200-2D100). Dealer replacement costs $1,800-3,000. Some owners have had success with the software update alone.
Owner tips & cautions
TipRequest the latest TCM software calibration from the dealer - newer versions significantly improve shift quality
TipLet the DCT warm up for 2-3 minutes before driving aggressively - cold clutch engagement causes most shuddering
WarningIf the transmission warning light comes on, get it inspected immediately - continued driving can damage the clutch beyond software repair

The panoramic sunroof glass on the Tucson can crack or shatter spontaneously without impact. The issue has been reported across multiple model years and has generated significant NHTSA complaints. Thermal stress from temperature differentials and body flex during driving are suspected contributing factors. The large glass panel size makes it more susceptible to stress fractures originating from the bonded edges.
Common Symptoms
Loud pop or cracking sound from roof
Spider-web cracks in sunroof glass
Glass shattered while parked
Water leak from cracked sunroof
Glass fragments falling into cabin
How to Fix
Replace the panoramic sunroof glass at the dealer. Hyundai has covered some replacements under goodwill warranty due to the volume of complaints. Document the damage with photos immediately and file an NHTSA complaint to support any warranty claim. Some owners opt to have a protective film applied after replacement, though this does not guarantee prevention.
The A/C compressor on the Tucson has a higher-than-average failure rate. The compressor clutch can fail first, making a screeching or grinding noise, followed by complete compressor seizure. When the compressor fails internally, metal debris contaminates the entire A/C system, requiring a full system flush. The condenser is also prone to developing leaks from road debris impact.
Common Symptoms
No cold air from A/C
Screeching noise when A/C is on
A/C clutch cycling rapidly
Warm air only from vents
A/C works intermittently
How to Fix
Replace the A/C compressor and receiver/drier. If metal debris is found, the entire system must be flushed including the condenser and evaporator, and the expansion valve replaced. Use only the correct PAG oil weight specified for the Tucson. Have the system evacuated and recharged with the exact R-134a or R-1234yf amount (depending on model year) specified on the underhood label.

Hyundai TSB 23-BD-009H covers certain model-year 2022-2023 Tucson vehicles equipped with non-glossy front door pull handles. The bulletin provides repair information when the front door pull-handle paint is peeling.
Common Symptoms
Paint peeling from a non-glossy front door pull handle
How to Fix
Confirm that the vehicle and handle finish fall within TSB 23-BD-009H. For a covered vehicle exhibiting the condition, Hyundai directs technicians to replace the front door trim panel assembly using the bulletin's repair procedure.
Rear brake calipers on Tucson models are prone to seizing due to corroded slide pins, causing uneven pad wear, pulling to one side, and premature rotor warping. The issue is worse in northern climates with road salt exposure. Some owners report rear brakes needing replacement at only 20,000-30,000 miles.
Common Symptoms
Vehicle pulls to one side when braking
Uneven brake pad wear
Grinding noise from rear brakes
Hot smell from rear wheels
Premature rear brake wear under 30k miles

Inspect and clean brake caliper slide pins, applying silicone-based caliper grease. If caliper piston is seized, replace the caliper ($100-200 per side). Replace pads and rotors as needed. Preventative maintenance: clean and re-grease slide pins at every brake service. Budget $300-700 per axle for pads, rotors, and caliper if needed.

The electromagnetic coupling unit for the AWD system in Tucson models can fail, causing loss of rear-wheel drive engagement. Symptoms include grinding noise from the rear, AWD warning light, and reduced traction in slippery conditions. The coupler motor or the coupling assembly itself wears out prematurely.
Common Symptoms
AWD warning light on dashboard
Grinding noise from rear
Loss of traction in snow/rain
Vibration at highway speed
Burning smell from rear
How to Fix
Diagnose with scan tool checking AWD coupling engagement. Replace the rear differential coupling assembly (Hyundai part 47800-2S500 for 2010-2015, 47800-D3500 for 2016-2021). Fluid should be changed every 30,000 miles using Hyundai genuine coupling fluid. Complete assembly replacement runs $800-1,500 at dealer, $500-900 at independent shops.

The GDI high-pressure fuel pump on 2.4L Tucson models can fail, causing extended crank times, rough idle, and stalling. The pump cam follower wears prematurely, reducing fuel rail pressure below specification. This is especially common above 80,000 miles.
Common Symptoms
Long crank before starting
Rough idle especially when cold
Engine stalling at stops
P0087 low fuel rail pressure code
Hesitation under acceleration
How to Fix
Diagnose by checking fuel rail pressure with a scan tool (should be 500-2,000 PSI depending on load). Replace the high-pressure fuel pump (Hyundai part 35320-2G740). Also inspect and replace the cam follower/roller. Parts cost $250-400, labor $200-400. Total $450-800.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

Tucsons finished in Hyundai's three-stage white pearl colors (Quartz White Pearl, Frost White Pearl) shed clear coat in sheets. The failure is delamination: the clear layer never bonded properly to the white base at the factory, typically because the base was sprayed thin, so the clear lifts at an edge and peels away in large patches. Horizontal, sun-exposed panels go first - roof, hood, and the tops of the fenders and liftgate. Owners describe it as peeling skin after a sunburn, and it is progressive rather than a chip-driven cosmetic issue. It affects Tucson alongside Sonata, Elantra and Santa Fe Sport, and has been reported in the US, Canada, Australia and South Africa. Following consumer-affairs news investigations Hyundai extended paint coverage rather than issue a recall - this is not a safety defect, but it destroys resale value. It is distinct from the interior pull-handle trim paint peeling issue.
Common Symptoms
Clear coat lifting and flaking off in large sheets
Roof and hood affected first
Dull chalky patches where clear has gone
Peeling spreads outward from an initial edge or chip
Predominantly on white pearl paint codes
How to Fix
Hyundai extended paint warranty coverage on affected white-painted vehicles from 3 years/36,000 miles to 10 years/unlimited miles from original retail delivery, and the coverage is transferable to subsequent owners. Open a claim through a Hyundai dealer with photographs and the VIN before the 10-year date - an approved claim gets the affected panels stripped and refinished at no charge. Do not wait for the peeling to spread, but do file before the ten-year cutoff. Out of coverage, a proper repair means sanding to the base and repainting each affected panel; spot blending over delamination will lift again.
