GMC Complaints

UNKOWN. It came like that. I took the truck to the dealership to be inspected and I was told that it was a manufacturing problem.

I have taken this vehicle to 2 different mechanics for "stuttering" during driving. Many times it will state a problem with stabilizer and lose power causing me to pull over in traffic as soon as possible. When this happens in snow it has become dangerous. Lately it just stutters without stabilization. No one has been able to find problem and sensors have already been changed. These occur at speeds of 2 mph to 75 mph intermittently

Engine oil cooler line crimp connections are not properly crimped and leaking oil whether the truck is operating or sitting off. It also appears the flare or threaded connection has failed. I went to the GM dealership who said my truck wasn’t part of the recall but my lines are very clearly the same affected parts and would not be available for repair under the recall. I suspect there are other trucks like mine that were missed in the initial recall. I had the lines inspected at another repair shop but all the GM oil cooler lines were unavailable and no back order was permitted. There have been no warning lights for low oil pressure yet but the worst level I have seen so far was only 3 of 8 in quarts in the oil pan. I’m afraid of the lines blowing out on the road and causing a total uncontrollable engine failure and oil slick for other drivers.

The stabilizer/traction control keeps going off and it will stay off.i can turn,hit a bump or start it up and the traction control/stabilizer system is off.i almost had a accident on the freeway in the rain because it turned off out of nowhere and I almost lost control. Also I was going down the road and all of a sudden my vehicle died and I had little control over vehicle. Once it came to stop it would not start again and when attempting it sounded like something was stuck in my fan or something because of the way it rattled and sounded and was rough sounding. Vehicle was inoperable and had to be towed. Upon investigating it was the timing chain kit that had failed suddenly for no apparent reason. Vehicle was well maintained and kept accordance with running policies and practices required and suggested by manufacturer. Still the failing caused engine damage that is well in to the several thousands of dollars and engine must be replaced due to this issue failing and I have noticed several thousand people having this same very issue and rendering them a foot and vehicle less due to the high cost of fixing without any warning or engine light or code suggesting of the timing chain kit failing or about to fail before stranding a person wherever and whenever unexpectedly and suddenly without any warning or check engine light at all. No OEM code to validate the issue either. Manufacturer should be held liable for the exact same issue occuring in so many of the multitude of people experiencing the same exact issue causing financial turmoil and risk of disaster or collision and harm when the timing chain kit fails suddenly. This is a huge and vast problem I have found with multitude of Acadia owners and should be addressed because to not honor a issue of so many experiencing the same issue occuring should be reconciled and corrected at the manufacturer cost due to it being their liability in making the faulty part of device to begin with causing vast financial hardships.

Truck RPMs were running really high between shifting with normal acceleration. I took the truck to a transmission shop as I purchased an extended warranty. The transmission needed to be rebuilt as many parts were worn. The extended warranty repair was made. After repairs, the truck has started doing the same thing 4 weeks later. It appears the transmission is not properly shifting again, I am not sure if it's a transmission issue as all parts have been replaced, or a computer issue that's causing the malfunction. The vehicle is available for inspection. My safety is put as risk because if the transmission does not shift properly, it is at risk at breaking while in motion which could potentially cause an accident and if the transmission breaks will on the highway, i dont know what type of risk that can entail. The transmission shop has indicated that they are noticing the same issue as before and do not see any reason for the issue to be continuing. There were no warning lamps or indicators that have shown up to indicate an issue. This is noticed by daily driving of the vehicle and noticing normal and not normal RPMs, shifting points and feeling.

Car has 100k miles on it. At 59k the fuel injectors went out and needed to be replaced. Then the transmission went out and needed to be replaced, then the front differential needed to be rebuilt, also had to replace the struts. Now the lifters are going out and that, plus likely the camshaft, need to be fixed. Total costs for all the above is close to $20,000. If not fixed these problems could easily result in catastrophic engine failure while driving leading to personal injury and death. I see that there is a class action lawsuit for the latter.

The transmission is shuddering, hard shifting, shuddering and lunging into gear. It is the 6L80 transmission Also has little to no power, took it to the dealership for diagnosis and they say the transmission is bad, torque converter is also bad sending metal throughout the rest of the transmission.

2016 GMC SIERRA SHARK FIN ANTENNA GETS WATER UNDER AND DESTROYS ONSTAR, NAVIGATION, AND COMPASS OPERATION. THIS IS RECALLED IN 2015 BUT DOES NOT INCLUDE 2016 THAT HAVE THE EXACT SAME PROBLEM.

I used the remote to open the rear hatch and pressed the button on the hatch to close it. While it was closing it traveled about half way back down and the rear window on the hatch exploded in my face. Glass went everywhere behind the SUV in a 5ft radius. I'm getting it repaired this upcoming Monday.

Recall for air bag was issued in May or 2023. So far no information on repair time, etc. Local dealers unable to provide more information. We have a vehicle that is dangerous to drive and need help resolving the issue.
