This Problem Across All Years
I am the owner of a 2021 GMC Yukon Denali with the 6.2L V8 engine (VIN: [XXX] ). This vehicle has exhibited multiple serious issues affecting safety, drivability, and reliability. 1. Engine Noise & Oil Consumption: Since purchase, the vehicle has had a persistent loud knocking/tapping sound, especially under acceleration. The engine also consumes an excessive amount of oil between scheduled oil changes, with no visible leaks. I reported this to the dealership multiple times, but since there is no active recall or TSB, they refused to diagnose or repair the issue under warranty. I have since learned that many other 2021 Yukon Denali owners with the same 6.2L engine are experiencing similar issues and some have had repairs or engine replacements covered by GM. I have received no such support. 2. Braking Problems: The vehicle has ongoing brake performance issues. Despite replacing the brake components multiple times, the brakes feel inconsistent and unsafe, especially during highway driving or sudden stops. There is vibration and uneven response, and the braking system does not inspire confidence. These problems have persisted despite attempts to correct them. 3. Suspension/Handling Concerns: The suspension feels unstable and loose, especially at highway speeds or when turning. The ride quality is poor, and there is noticeable sway and body roll, which creates discomfort and concern for vehicle control. 4. Fuel/Propulsion System: The engine does not always respond smoothly to throttle input. I’ve noticed occasional hesitation or surging, which may be related to the previously mentioned oil consumption or fuel delivery. Again, the dealership has been unable or unwilling to resolve these issues without charging diagnostic fees. I’ve reported these issues to my local GMC dealer on multiple occasions, but no lasting solution has been provided, and I have not been able to afford expensive diagnostic costs out of pocket—especially for a vehicle of this price INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

On [XXX] I brought my vehicle to Rivard Buick GMC with a squeaking noise that was check and attempted to be repair four times at the same location. They provided a quote for $2,309.10 stating it was the Master Cylinder. Rick the Services director said it was not cover under warranty and it need it to be cover by me, at that point I explain to him the vehicle has been in and out of his services department for the same issue since it had 20,000 miles. 1st time-They replaced the front brake pad stating GM had a defect on them (Noise went away for a few thousand miles) 2nd time- They apply conditioner to the brake and lubricant so they say (noise went away for a few thousand miles) 3rd time- They said it was not the front brakes anymore making the noise. They said warranty did not cover rear brakes due to GM not flagging it as defected pad. I complained the noise was coming from the front of the vehicle but they insisted it was the rear so I paid $500 plus to get the rear brakes at 60% life left on them. At the time of picking up the vehicle after repair completed the noise came back within a few miles from the dealer. I returned to the dealer and spoke with the Services Manager Troy, he apologized for the inconvenience and said they will take care the front brake at no cost to me, however they submitted a claim to GM to get the work done and kept my money when they misdiagnosed the issue. 4th time- Noise comes back at this point the warranty it's expired and they tell me it's the master cylinder the actual issue. When I talked to Rick, he said that GM was willing to pay for half of the work and the other half it's my responsibility. On [XXX], my wife and three kids almost hit a wall while trying to stop and the braked did not work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my check engine light came on indicating that service was needed on the Electronic Stability Control (ESC), traction control, Anti-Lock Brake System (ABS), brake assist the vehicle top speed reduced to 43mph. My braking system was compromised and I have to travel at reduced speeds on busy roadways to arrive at my destinations. I have taken the vehicle to a certified GMC technician for diagnostics and repair.

The contact owns a 2021 GMC Yukon XL. The contact stated that on numerous occasions while driving approximately 70 MPH, the brake pedal engaged without warning, then the vehicle proceeded to accelerate independently. As a result, the vehicle inadvertently stopped and jerked forward. No warning lights were illuminated. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 20,504.

GM CHANGED THE TRAVEL OF THE STEERING COLUMN SO NOW IT'S ONLY A FEW INCHES FROM THE DASHBOARD. IN PRIOR MODELS, THE STEERING WHEEL (SW) TRAVEL WAS MUCH MORE. DUE TO GM'S DESIRE TO SAVE MONEY AND COMPLETE DISREGARD FOR DRIVER, PASSENGER AND OTHER VEHICLES SAFETY, THE DRIVER HAS TO REACH OUT TO THE SW RESULTING AT DANGEROUS ELBOW ANGLES. IN PERFORMANCE CARS, THE SW IS DESIGNED TO BE CLOSE TO THE DRIVER BECAUSE PHYSICS PRINCIPLES OF TORQUE REVEAL: THE GREATER THE ANGLE OF REACH, THE MORE TORQUE IT REQUIRES TO TURN THE SW. SO REACHING OUT WITH THE ELBOW AT ZERO TO 10 DEGREES REQUIRES A MUCH LONGER REACH, THUS GREATER FORCE/TORQUE AND LONGER REACTION TIME, THAN HAVING THE SW AT A 30-40 DEGREE 'ELBOW BEND'. THE POINT IS, FOR A DRIVER TO TURN THE SW ON THIS VEHICLE, IT TAKES TOO MUCH STRENGTH AND TOO LONG A REACTION TIME TO SAFELY OPERATE IT. I DO NOT FEEL SAFE DRIVING THIS MODEL LIKE I DID WITH PRIOR MODEL YEARS. WITH THIS 'LAND YACHT' HAVING AN EVEN LONGER WHEELBASE THAN BEFORE, THE DISTANCE TO THE SW IS EVEN MORE CRITICAL IN REGARDS TO REACTION TIME AND SAFE DRIVING! PLUS, SINCE THE SW IS SO CLOSE TO THE DASHBOARD, WHEN I RAISE MY LEG TO STEP ON THE BRAKE PEDAL (WHICH NOW I HAVE TO DO BECAUSE GM ALSO TOOK AWAY THE FOOT PEDAL ADJUSTER!), MY LEG HITS THE BOTTOM OF THE SW! THE TIME IT NOW TAKES TO BRING A FOOT UP OVER THE BRAKE PEDAL, TO LOOK DOWN TO SEE IF YOUR LEG IS GOING TO HIT THE SW AND CAUSE THE SW TO EITHER STOP MOVING OR RE-DIRECT THE VEHICLE INTO AN UNPLANNED DIRECTION, ALL WHILE TRYING TO STOP THIS OVER 7,700 LB VEHICLE WITH MUSHIER BRAKES THAN ANY MODEL EVER, IS DANGEROUSLY LONG. THE OVERALL REACTION TIME TO GENERALLY STOP THIS MODEL IS AT LEAST 5 TIMES THAT OF MY 2018 YUKON XL DENALI. THE TRAVEL LENGTH OF THE SW NEEDS TO BE INCREASED 2-3 INCHES TO SAFELY OPERATE THIS TRUCK. GM MUST BE HELD ACCOUNTABLE FOR INCREASING DANGEROUS SITUATIONS WITH THEIR VEHICLES!
