2017-2025 Cadillac XT5 Problems: 20 Known Issues

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.

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.

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.

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.

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.

GM says some owners may feel shudders or shakes at low speeds, possibly caused by torque converter clutch (TCC) shudder on shift and/or poor TCC control. The transmission fluid may be contaminated and/or the torque converter damaged. Applies to: 2020-2025 Cadillac XT5 with the 3.6L V6 (LGX) and the 9-speed automatic RPO M3W, as listed in the September 2024 version of GM bulletin 23-NA-072 (which replaced PIP5608J).

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.

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.

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.

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.

A 2023 XT5 owner reported the front sunroof glass breaking while driving, about one month after acquiring the vehicle. The owner described glass falling from the vehicle and reported that the interior cover was closed. This is an owner allegation recorded by NHTSA, not a confirmed cause or a finding that all XT5 sunroofs are defective. Applies to: 2023 Cadillac XT5 equipped with the panoramic sunroof. This view describes NHTSA complaint ODI 11505075; it does not establish a failure rate, exact speed, cause or repair outcome.

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.

GM bulletin 20-NA-232 describes a power liftgate that stops shortly after opening, or will not power-close from the open position. Technicians may find DTC B153F. Misaligned or dimensionally unstable terminals in the liftgate object-sensor connector can cause intermittent contact. This bulletin covers 2017–2021 Cadillac XT5; it does not establish a strut failure or apply to 2023.

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.

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.

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.

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 limited to a short build window (XT5s built April 16 to May 9, 2016), not a wear item, and it is separate from the more familiar XT5 rotor and pad complaints.

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. NHTSA lists 736 vehicles in the campaign across all three models.

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 steering module needs a valid coolant-temperature signal to compensate for cold, thick steering-gear grease, it stores U0401 and the driver gets a 'Steering Assist is Reduced - Drive With Care' message, sometimes with noticeably heavier steering effort. Owners report this in NHTSA filings, and GM bulletin 17-NA-158 documents it for the 2017 XT5 with the LGX. It is a cooling-system fault masquerading as a steering fault, which is why many owners are first quoted power-steering diagnostics.

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.
