GMC Complaints

My 2016 GMC Yukon Denali was taken in for a tune up. When I received the vehicle back, I was told that there was possibly a microscopic pin hole in my engine because fluid (engine coolant) was under one of the injectors. I was told that I may need to trade in or get another engine. I refused both. The mileage at the time was probably 120,000. I purchased this vehicle brand new and do not see how an engine is needed so quickly. I was barely finished paying for it. I was told by a co-worker that she had to trade hers in because it was doing the same thing. She had also investigated and had learned that many of these vehicles have the same issues around 114,000 miles and beyond. I think these issues need to be addressed.

Brakes go out at low speeds, especially in reverse. Makes it really hard to stop vehicle. It happens at least once every couple days and seems to be getting progressively worse.

The frame of the rear window cracked which allowed water to enter the cab. Water made its way onto the rear anchor strap of a car seat and saturated it which could have caused it to possibly not perform properly, which could have injured a child. Since the rear window can be opened electrically it is possible that a short could occur due to the water intrusion. GM has a service bulletin out about resealing the window but will not cover the repair or replacement of the window if it is outside the 36,000 mile warranty period. Obviously this is a manufacturer defect that has numerous occurrences or there would not be a bulletin created for it.

The “steering assist reduced. Drive with care” A/C turns off and fan kicks on high. Transmission temp flatlines. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2014 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed that the parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available.

My engine went out, and I had to have it rebuilt. There was a check engine light on. My steering goes out and in without warning while driving. I have talked to the dealership, and they stated that all safety recalls were done on my vehicle. My safety and those of others were put at risk when the steering failed. I almost crashed my vehicle in traffic. There were no warning messages prior to the failure. I did see that there was a recall in 2019 and the dealership will not inspect the vehicle without payment.

At low speeds, while turning rapidly steering would get stiff and then come back on.On two occasions, lights would flicker and a steering power loss warning would briefly appear, and then disappear

Break get rock hard at times and makes it almost impossible to stop at a safe distance

The vehicle steering wheel shudders at speeds from 40-55mph. The steering wheel shudders at 2-second intervals and is constant between those speeds. At first, I thought it might be one of the safety systems. It is not. This is unsafe and GM should be held responsible.

Super cruise does not work. It may turn on at random for a minute or 2 and then it shuts off with zero warning and the vehicle almost comes to a complete stop. This is a huge safety concern. I took it to the dealership and they told me that this falls on GM 100% as they are being told GMs engineers are trying to find a fix but for now there is nothing they can do, I am to continue driving it knowing this is unsafe. The turn signals and Bluetooth stopped functioning for no reason which had to be fixed Battery charging module burned up at 300 miles. I asked for a buy back and GM refused. I asked for an engineer to come on site and they refused to set it up unless something else is happening as if this super cruise issue isn’t enough. I filed a complaint with the BBB hoping to get the attention of someone who would actually realize how unsafe this is and that same person from GM lied and said I declined assistance. I asked that lady for help and she stated that it would have to wait until something else happened.
