GMC Complaints

Driving on the highway the engine suddenly revved high and suddenly went into limp mode on the highway. Reverse is no longer operational. 2022 GMC Yukon with 49,000 miles. Limped the vehicle to the dealership who has indicated it needs a new transmission valve body that is currently on national backorder given the prevalence of the issue. I have been requesting a work order denoting the failure and required repair but have not yet received from my dealership. I will pass this along as soon as I receive it. I spoke with GM customer service last night requesting their assistance in getting this for me.

was getting on the interstate whenever i hit 70 mph just heard a hard knock in the engine and truck was driving rough. the truck it self dropped to 60mph. before it occurred there was no check engine light on or anything. after i had the dash light up with engine light, brake light, stability light. about a week later took it to the dealer they said it was fuel injectors they replaced it took them about 2weeks but the problem wasn’t resolved but then stated it was the lifters which they said it almost common for this to happened. so i took it somewhere else to get replaced and they said yes it was the lifters and i needed to replace the camshaft because when the lifters go out it will damage the camshaft. all they did to diagnose my problem was hear it was ticking and the knocks also with the codes from the dealer diagnosis. after my repairs it was expensive least to say

2022 GMC Yukon Denali, 6.2 with 37,000. Bearings failed. Needs a new motor. 150 miles away from home. Engine failed with no warning on a highway. Had to call police to assist. Paid for a tow truck out of pocket. Covered Under powertrain warranty, Unsure if I will get a new or refurbished motor. I was told by the dealership that lead times could exceed two months. GM is not extending my powertrain warranty.

Torque converter is going bad, hard shift when going slow then speeding up, stuttering at random times, vibration, hard shifting into reverse. No check engine light. Acadia known for transmission and torque converter problems.

ENGINE FAILURE We were stranded on the side of the road on a trip back from Florida Vehicle had to be towed the a dealership back in Houston no warnings This is the second engine failure (original engine and the 1st replacement engine) basically we are on the 3rd engine in this vehicle.

I am writing to express my concern regarding a serious issue with my 2021 GMC Yukon. Recently, while driving, I experienced a sudden surge in power. About five minutes later, when attempting to shift into reverse, the vehicle would not respond. I tried multiple times with no success. Afterward, while driving it briefly around the block, it made a clunking sound, which raised further concern. Ultimately, I had to call a tow truck, and the vehicle was taken to George Gee GMC in Liberty Lake, Washington. Unfortunately, the next day the dealership was unable to duplicate the issue. There were no warning messages on the screen at the time of the incident, and no diagnostic codes were found, so they could not move forward with any repair. I later discovered that this exact issue is addressed in Technical Service Bulletin N242454441-02. However, I was informed that my VIN is not included in the special coverage, despite my vehicle being the same year and equipped with the same transmission mentioned in the bulletin. I am deeply concerned that this problem could happen again—possibly while I am driving in Canada, transporting my children, or in a location where calling a tow truck would be very difficult. My safety and my family’s safety are at risk, and frankly, I am now anxious about driving a vehicle I used to trust. I also have an extended warranty, but when I contacted GM service, I was told that unless the problem can be duplicated, it would not be covered. This is extremely frustrating given the severity of the issue and the fact that it is already documented in an official bulletin. I am requesting that this situation be escalated. I would appreciate any additional support, coverage, or guidance GM can offer to help ensure this issue is resolved and does not put me or my family at risk again.

My 2018 GMC Acadia is experiencing an issue with the "Shift to Park" feature. When the vehicle comes to a stop and is put into park an alert comes up on the dashboard says "Shift to Park" even though the car is fully parked. This keeps the vehicle from being able to be turned off. Often times this issue is not fixed by turning the car on and re-shifting to park and i have to drive the vehicle and try again. This happens over 50% of the time I try to park this vehicle.

On [XXX] while driving 80mph on Westbound [XXX] , just West of the [XXX] exit, my engine simply quit. I was able to navigate it to the side of the highway to avoid traffic. However I could not restart the engine or subsequently get it out of Park gear. I got a notice "Conditions Not Correct for Shift." I was forced to use Onstar to get the truck towed back to the original dealership, Quebedeaux Buick/GMC in Tucson, Arizona. The next day, Monday, I went to the dealership to find out what happened to my truck. They said they would call me with results. They never did. The next day, Tuesday, I still hadn't received a call. I returned to the dealership to ask what had happened. They informed me the engine had thrown a bearing and it would need a total engine replacement. It would take 1-2 months. I'm now on day 4 of not having a vehicle, I've called the dealership every day to try to get a loaner vehicle, and they keep telling me they're working on it. The truck only has 36k miles on it and is still covered by warranty, but I feel like I'm getting the runaround from both the dealership and customer service. I still do not have a loaner vehicle.
