DFM Lifter Failure on V8 Engines
The Yukon's 5.3L and 6.2L V8 engines are afflicted by the same DFM lifter collapse problem as all other T1XX platform vehicles. The NHTSA has received 63 engine-related complaints for the 2022 Yukon at an average of just 7,651 miles. Symptoms include engine ticking, misfires, and loss of power.
Dealer replaces lifters, VLOM, and camshaft as necessary under powertrain warranty. GM's Component Coverage program provides extended warranty for vehicles with repeated lifter repairs. Owners may also consider aftermarket DFM disable devices as a preventive measure.
Est. Cost: $1,500 - $4,000 (typically warranty covered)6.2L V8 Connecting Rod and Crankshaft Manufacturing Defect
Certain 2021-2024 Yukon models with the 6.2L V8 have potentially defective connecting rod and crankshaft components. Manufacturing defects in these critical engine parts can lead to complete engine failure, posing a serious crash risk due to sudden loss of power, steering assist, and brake assist.
NHTSA Recall N252494000. Dealers inspect the engine and repair or replace as needed. Preventive measures applied to vehicles passing inspection. All repairs performed free of charge.
Est. Cost: $0 (recall repair)Incorrect Fuel Tank on Diesel Models
Certain 2022 Yukon models equipped with the 3.0L Duramax diesel engine may have had the original fuel tank replaced with an incorrect fuel tank during a prior service visit. The incorrect tank can allow fuel to leak in a rollover crash, increasing fire risk.
GM recall issued to inspect and replace the fuel tank with the correct part if an incorrect tank was installed. The repair is performed free of charge at the dealer.
Est. Cost: $0 (recall repair)Daytime Running Lights Fail to Deactivate
The DRLs may remain illuminated when the headlights are turned on, creating excessive glare for oncoming drivers. This lighting malfunction violates FMVSS requirements and can reduce nighttime visibility safety for both the Yukon driver and other road users.
NHTSA recall for 2022-2023 models. Dealers update the BCM software, or the fix is available via OTA update. Free of charge.
Est. Cost: $0 (recall repair)Front Suspension Noise and Component Wear
Owners report knocking, popping, and snapping noises from the front suspension area when driving over bumps. The noise is most pronounced at low speeds. Common culprits include worn stabilizer bar end links, upper control arm ball joints, and on Denali models with MagneRide, leaking adaptive shock absorbers.
Replace stabilizer bar end links and inspect ball joints. For MagneRide-equipped models, replace leaking magnetic ride control shocks. Perform a complete front end inspection to identify all worn components. Strut mount replacement may also be needed.
Est. Cost: $250 - $2,800 (MagneRide shocks add significant cost)
