GMC Complaints

I was driving on a normal local highway and my car started to slow and an indicator to 'press start' to restart the engine came up. I tried to do that and the engine wouldn't turn over. My car sputtered to a stop during rush hour traffic as I was able to drift over to side of the road. The car wouldn't start after that, waiting for 10-20 minutes and re-trying wouldn't work either. I had to have it towed and am now awaiting a fuel pump module that is on back order. No warnings to me that it would happen and I fear that this could have happened on the highway at high speeds, causing a crash. My car is a large SUV that takes a lot to stop, the car just sputtering and dying is unacceptable. I see my car wasn't included in the recall of this issue back in 2021, but I believe it was manufactured during the impacted window and I took deliver in May of 2021 of the new car. I think more cars should be recalled to prevent this from happening to other people. Very scary when it happens and the alternative situations it can happen in, especially for such a large vehicle that typically is carrying multiple passengers.

The contact owns a 2012 GMC Terrain. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to coast the vehicle to the shoulder of the roadway, and the vehicle failed to restart. No warning lights were illuminated. The vehicle was not taken to the dealer nor an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

I have a 2017 GMC Acadia with what I call a "Shift to Park" issue. This originally showed up with about 27,XXX miles on the car. It was repaired by the dealer on 9/25/2019. It worked perfectly until it started back up about six weeks or so ago with approximately 57,XXX miles on the car. I was told when it was originally fixed that they knew the issue and had an earnest fix. Not they want >$500 to fix a problem that they were supposed to fix the first time. Here is the issue. When you shift to park, and try to turn the car off, you get an error message that you need to "shift to park". I assume that the car is in park, but not sure with this warning message. You have to start it back up multiple times and play with the shifter. The other option is to let the warning keep flashing and wear the battery down. I have replied the battery on this car two times. When researching this issue on the internet, I see that there are several class action lawsuit for this issue so GM is well aware of the issue. They have apparently figured out the issue because it only affected the 2017 and 2018 Acadias from what I can tell. AS you can tell fro the mileage, this car has low annual miles and ha always been serviced by a GM dealer.

The Flex Tailgate has on multiple occasions has malfunctioned in cold temperatures. I have had instances where I can get it open when I have vital supplies in the bed of my truck because of the Tonneau Cover being on (I have a hard cover made for this truck) and the tailgate malfunctioning. I have also had an instance where my tailgate opened (after clicking shut) while driving without the notification coming up on my dash. I could've been held liable if my equipment fell out and caused an accident. Moral of the story this truck as a lot of issues when temps are below freezing even after being warmed up for 15 minutes or longer. I wouldn't recommend this truck based on the function of the Flex Tailgate. I would prefer a classic a handle and less tech now that I have seen it fail so many times.

The contact owns a 2015 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 contacted. 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. The contact had not experienced a failure. VIN tool confirms parts not available.

We drove our Truck from Hartwell Georgia to Coloma Wisconsin on [XXX]. En route we drove through heavy rain. We got to Coloma on [XXX]. The truck sat outside overnight in cold weather. Temps were in the low 20's to high teens. On [XXX] I went out to drive the truck to town on errands. After starting it the steering would not move. Had the truck towed to Wheelers Chevrolet of Coloma. Weather had warmed up and the steering was working. The dealer kept the truck and let it sit outside overnight. The next morning they started it and the steering would not move. The brought the truck into the heated garage and after a hour or so the steering worked. They decided to keep it inside and dry it out. It sat in a heated garage till noon on the [XXX] at which time I took the truck to my wife's brother house and put it in a heated garage till we left on the morning of the [XXX] to head back home. Temps all day were below zero. We pulled off the road after about two hours and the steering began to bind up. Rotating the wheel got it loosened up and we elected to continue. About 15 minutes later on [XXX] at highway speed the steering began to lock up. I managed to get it to the side of the road. . Again rotating the wheel side to side for about 5 minutes got it to free up. We continued and made it home. Clearly there is water somewhere in the steering. Pretty scary having locked steering at speed. No problems in warm weather. I will be going to my GMC dealer today. Richard Kay superstore in Anderson SC. My service techs name at Wheelers Chevy was David Borre. Phone number 715-600-3358 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This car had catastrophic engine failure due to the lifters, push rods and camshaft. This car make and model and engine type is notorious for these specific parts to malfunction. This could have left myself and my children stranded on the interstate. The vehicle has been inspected by a certified master technician with ASE training. They confirmed that these parts are a common issue with these cars.

Lifters Failed in November 2023 and had repaired major engine damage including 4 cylinders, cam shaft, lifters, gaskets etc. After major repair work done. Truck is now doing same exact thing in January 2024. The dealership is stating they will not look at the vehicle unless i buy a new battery. I asked them to try a used battery to see if that makes a difference. And then if it is the battery i will replace. I was hung up on after the technician doug Pedersen stated ill have a supervisor call you back.

Vehicle brakes went completely hard and vehicle would not stop. There was no warning signs, no lights on the dash and vehicle was driving on highway normally. Upon taking a highway exit, I could not stop the vehicle, completely unexpectedly. Upon further research it is a very common problem that needs to be addressed. My 3 kids and wife were in the vehicle when it happened, and this is actually the second time it has happened. The first time it happened we could not stop the vehicle at all to turn onto the road I live on, could barely push the brake pedal and coast to a stop. The repair last time it happened was the camshaft driven brake booster vacuum pump, and it has failed again after 20,000 miles. This is a serious manufacturer defect that has almost killed my family twice now.

When I hit the brakes it has no stopping power, hard to push brake pedal and when sitting at a complete stop it has been known to start going even though I have foot on brake.
