  • 2024 GMC ACADIA
    - Troy, NY

    2024 brand new Acadia Denali trim with 1k miles was brought in to the dealership because of 'popping' and 'grinding' noise when turning, most loudest when turning to and from the right. It was also very much felt on the steering wheel. Dealer took apart the front right strut assembly and said that it was not 'installed' properly, causing the springs to hit the fender everytime the wheels turned. They inspected it said that nothing needed to be replaced, installed it properly, test drove it and determined that it was fixed. Driving home, I sped through potholes and bumps, especially during turns, to really test their repairs. Luckily, the sound was gone, steering was smooth. And I hope it stays that way. Out of curiosity, I took a picture of the strut assembly post Repair You can see the coil is bulging out of place from the strut. This is only in the right side. The pictures show the suspension with wheels fully turned to the right, left, and pointed straight. The picture even shows the part of the fender where the spring made contact with. I communicated in online groups of acadia owners and they said it’s also the same issue, wherein that they experienced the symptoms themselves or the struts look misaligned already. I believe this is a concern GMC should address the soonest as it could lead to road hazards for everyone involved.

  • 2022 GMC YUKON XL
    - Clyde Park, MT

    As we were leaving Cortez, CO. on a two lane highway we were passing a couple of cars with plenty of room to get back into to the driving lane when we lost ALL power from the engine. The cars we had just passed had to slam on their brakes as we were trying to keep from a head on collision. But with no power and the Denali in neutral we couldn’t change anything. We coasted to a County Road approach and it DIED in the middle of it. NO POWER. We had to call a tow truck who took it back into Cortez to Webb Chevrolet. The engine had seized. God was watching over us that day. We have since found out that there has been MANY seized engines with the 2022, 6.2 liter engines. In many new pickups and few of the suburbans. In fact, the Webb Chevrolet people said they have had one that they replaced the seized engine with a new 6.2 liter engine and in 500 miles that NEW ENGINE ALSO SEIZED! This is a MAJOR SAFTEY ISSUE!! THIS ENGINE NEEDS TO BE RECALLED BEFORE IT RUINS LIVES OF THE FAMILIES WHO ARE DRIVING THEM!!. We only had 42,000 miles on our 2022 Yukon Denali and Chevrolet couldn’t even rent a vehicle to get home and it would be a month to have to wait for a new one. We had to trade vehicles to get home. Point is, when the engine seizes while passing cars on a two lane, somebody is going to die. Families aren’t at fault when the company has been notified of their negligence to get a recall on this engine and fixed. We’ve had our Denali in for service several times for electrical issues. This should qualify as a Lemon Law. Instead, GMC tried to send a $5000.00 voucher to use when we buy a new vehicle. This family has bought GMC, CADILAC’S, CHEVY’S FOR OVER 50 years. We like our salesman and would continue this business, but not if you don’t make SAFETY FIRST!! RECALL THIS ENGINE NOW!!! Take care of YOUR customers and OUR friends! LOOK FOR YOURSELF THE AMOUNT OF SEIZED ENGINES IN THIS 6.2LITER ENGINE. Thank You, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

  • 2024 GMC CANYON
    - Mount Airy , MD

    The headlights are malfunctioning where they periodically flicker and there is a loss of lighting. The frequency seems to increase the longer the headlights are on and in use. The loss of lighting during the event increases risks of driving at night and impairing oncoming traffic. Yes, the problem has been confirmed and documented by my dealer, Ideal Buick GMC in Frederick MD Yes, Dealer inspected the problem, replaced parts but the problem still exists. No other indications of failure. Symptoms appeared immediately after taking delivery of vehicle.
