GMC Complaints

Low engine oil message keeps flashing after less than 2,000 miles of driver. Excessive oil consumption. Took vehicle to GMC dealership and it was confirmed that an engine replacement or replacement of the pistons and rings is necessary. Only 77,000 miles on the vehicle. My car is currently not a part of the massive recall.

The contact owns a 2025 GMC Sierra 2500. The contact researched online and became aware that there was a recent recall under NHTSA Campaign Number: 25V815000 (Equipment) for the Owner's Manual. The contact stated that the vehicle was sold without the Owner's Manual. The contact stated that the manufacturer was called and was advised that the recall was only related to the 2026 Chevrolet Silverado models and the vehicle was not the same year, make or model. The contact was attempting to retain a physical copy of the Owner’s Manual and thought that it was a safety issue since there was a safety recall. The contact had not experienced a failure.

The contact owns a 2019 GMC Sierra 1500. The contact stated that the rearview camera displayed a black screen while the vehicle was in reverse(R). The contact stated that the failure obstructed driving visibility, preventing the driver from safely operating the vehicle. The vehicle was taken to the dealer; however, the contact was informed by the dealer that the part needed for the recall repair was not available. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was not notified of the failure. The failure mileage was unknown.

I accidentally ran out of gas and my car died directly underneath a railroad crossing arm. I had been stopped to allow an Amtrak train to go by and my car died when I started to move forward after it passed. Thankfully I wasn't on the tracks, but I was close to them. I immediately got out of my car and the woman behind me said she would help push me out of the way of the crossing arm. I went to put my car in neutral, something I do weekly when I go through the car wash, but my dash kept saying "conditions not correct for shift". I tried repeatedly and it would not allow me to put the car in neutral because I couldn't fully turn it on. I did a quick search online and found there was no information on how to get it into neutral if the car is dead. My battery was still working and my car was in accessory while I was trying to change gears. I had to call 911 and they had to reach out to BNSF to alert incoming trains. It was an ordeal. I spotted a tree removal company across the street and they had a can of gas for me to use. I was able to partially fill my tank and then drive across the tracks before a train came. Afterwards I called the dealer and we discovered together that there is no backup safety feature that allows a disabled car to be put into neutral. The dealer was just as surprised as me. This seems like an obvious safety issue if a car is to break down on train tracks, the middle of the freeway, or in an intersection. I don't understand why it is allowed and why dealerships and the public are seemingly unaware of it.

I had taken our GMC Sierra 2500 with LT275/R20 Goodyear Wrangler tires into Henderson Chevrolet for maintenance and to have the tires checked. The technician stated that the front tires were showing tread separation. I was shocked because the tires only had around 20,000 miles. The truck is not used for towing and is kept in the garage away from the sun. I asked the technician to double check the rear tires for separation and he stated they were fine. A couple of weeks later, I was driving to California and there was a loud bang on the rear driver side. The truck indicated the the tire was losing pressure. I pulled over to the side of the busy road as soon as possible. The entire tread was missing form the tire and when it came off it damaged the wheel well and the rear bumper and taillight.There was a lot of traffic on the highway and not much shoulder it was a pretty scary and unsafe situation I but got the tire changed with the spare. About an hour later the passenger side tire blew up, there was way more damage on this side including bent exhaust and damage to the fender. I had to get roadside assistance to change the tire so I changed both rear tires so i could have a spare.When I took the car back to Henderson Chevrolet they told me this is a common problem they have had 10 in the last 6 months. Boulder Autobody said they had seen 7 in the last 6 months. Henderson Chevrolet sent both tires to Goodyear to be examined and they conveniently lost one of them and stated that the tires were not defective. Thank goodness no one was hurt, this could have easily killed someone.

experience a automatic OTA update to the info system on my 2021 GMC Sierra(I did not iniciate) which burnt out the radio module which controls the info system. I am being charged $1,300+ for repair due to vehicle being out of warranty(52,000 miles) and no recall on this vehicle model for this issue. GMC does have a recall for this exact issue on the 2021 GMC Tahoe models, but not the GMC Sierra. If the GMC utilizes the same componets for both models of vehicle how doe the recall#N202319250 not cover the exact same issue on both models?

The contact owns a 2018 GMC Acadia. The contact stated that after shifting to the park(P), there was an audible warning alarm activated, and the message "Shift to Park" was displayed, and the vehicle failed to immediately turn off. After restarting the vehicle and jiggling the gear shifter, the failure was corrected. The vehicle was taken to the local dealer, who diagnosed the vehicle and determined that the gear shifter assembly was faulty and needed to be replaced. The vehicle was repaired, but while picking up her daughter from school, the gear shifter was shifted into park(P), and moments later, the vehicle started rolling backwards. The contact had to activate the parking brake to stop the vehicle. The vehicle was later towed back to the dealer. The cause of the failure was not yet determined. The manufacturer was not notified of the failures. The failure mileage was 120,000.

I bought this Terrain brand new from Betten Baker Chevrolet in Muskegon Mi in 2019 with 500 miles. That same year we had transmission Slippage causing it to slip out of gear then slam back into gear while driving. I took it to the dealer to have it looked at. They did nothing and informed me it was known by the manufacturer that this was an issue. I then had to bring it back for electrical issues as the lights would all start going off in the cab including dome lights and shift buttons. All key fob would not be recognized by the car and would have to be reprogrammed counting 5 times now. Now I am sitting at just oflver 100,000 miles and what I thought was going to be a simple spark plug change gas turned into a complete motor failure. did an oil change and there was no oil in it. The turbo was replaced and now the engine started making a lot of rattling noises and just stopped. the dash says service transmission, ECS, Extremely low battery voltage and has jost die after oil started pouring out the bottom of the car. It is now sitting at the dealership service department where I was told by am employee there that they have been seeing them come in at 150,000 miles for complete rebuilds and mine was early. let me tell you that this car isn't even paid off yet. And the 2006 Ram 1500 is more reliable.

The rear view camera fails to function intermittently and is occurring at a higher rate of frequency. On numerous occasions when the vehicle is put in reverse the screen goes black with a red triangle caution symbol and a white camera crossed out. Now the system is unavailable more then operational. Based on the drivers rear vision when backing in this particular vehicle, the lack of the rear camera view increases the risk of crash. This also increases the risk of severe injury to a pedestrian behind the vehicle. The same issues were addressed on earlier models via a safety recall which should be extended to 2023 model.

Engine malfunction, had dealer look at truck and they said I needed a new engine, check engine light came on and a knocking noise appeared suddenly. Reading about 2021+ sierra with 6.2 engine that has a recall with the same problem as mine. Wondering why that recall wasn’t extended to my truck as well.
