GMC Complaints

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving on the highway at 70 MPH and depressing the accelerator pedal, the vehicle failed to accelerate as needed, and the vehicle started losing automotive power. The contact pulled over to the side of the highway and turned off the vehicle; however, the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to a local dealer where the vehicle was diagnosed, and the contact was informed that the push rods were faulty, and that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage 25,000

Oil is burning through. I have to get an oil change once a month or it goes completely empty. Spoke to multiple macanics now and all tell me that's a defect with the 2017 arcadia. I just bought this in August. I love it and don't want to get rid of it. Please fix this. I can't keep burning through oil like this. It's not safe for my kids and I

on 12/14/24 my engine shut off while passing 18 wheeler, on my dash it said: start vehicle again. Vehicle had no power and i was forced to pull over on the side of the road. Was not able to crank the vehicle and a tow truck was called to tow my truck to the dealer. A week later i was told there was metal in the oil filter and engine replacement was required

Engine failure with no prior warning 11/21/2023. We were on the highway. Truck made some noises and hesitated and stalled within 2 minutes. Thankfully, there was an off ramp and we were able to roll into a gas station. Had it towed to a GMC dealer. GMC dealer confirmed engine was blown. Dealer confirmed it's a known issue.

Our 2019 was repaired back in 2021 for a "shift to park" issue. This same issue is happening again after 2 years of being repaired. We see that there is a major issue with GMC vehicles and there have been recalls for this same exact issue. GMC Coleman, Lawrence NJ is refusing to fix problem under a recall. We would like this to be covered or reimbursed.

Definitely needs an engine. Will get a new engine, radiator and oil cooler lines ordered Rear pinion seal on the rear differential was leaking also so I've ordered one of those and will replace it

Driving home from dropping my daughter off at school. When slowing down at stop sign, car locked up brakes completely, almost went through stop sign, car shut down engine and placed vehicle in park. Diagnosis is a vacuum pump failure, causing reluctor wheel to spin freely from camshaft. This happened without warning at 70k miles. Diagnostic report from three weeks prior showed no bad diagnostics with engine or drivetrain components, or brake components. Had to have car towed from intersection where i was impeding traffic due to sudden failure. Garage is concerned regarding potential for debris and engine damage, as well as timing issues due to sudden failure of vacuum pump. GM has authorized vacuum pump recalls on other makes from prior years, not Terrain for some reason. This is how becoming highly reported failure among GMC/Chevy vehicles with shaft driven vacuum pump design between 2019-2022. GM has stopped using this design on 23 and newer models. They should absolutely recall these older models for this issue. Sudden vacuum pump failure can lead to unrepairable engine damage due to design.

I was driving my vehicle to the gym when I noticed it was driving weird, it would not accelerate like normal, was having a hard time getting going and was making a weird noise. I had just put some oil in the car because we had known for a little while that it had a problem with burning oil because of the make and model (as told by other mechanics previously), when I got to the gym I heard a pop noise and the car stalled on me, I eventually got it started up again after 2 hours of being stranded at the gym. The next day I had to drive 40 minutes away for nursing school Clincial where on the way home it was back to driving weird and making a loud horrible noise from the engine. I was only 5 minutes from home when it was really bad and once there I noticed the burning smell from the engine. When I checked the oil level after an hour and half of cooling down I could not get any oil reading on the dipstick, after adding almost 4 quarts there was still no reading on the dipstick. We finally drove the car to my mechanic (8 minutes away) and it was already back to making the loud noise, having trouble accelerating, and producing the foul odor. I was told the PCV was restricted and caused the engine to over pressurize and that lead to the Main Rear bursting and all the oil in my car being thrown over the entire underside and probably the roads. They also checked the oil filter in the car to see if the engine itself was salvageable, where they found metal flakes in the oil filter and deemed the engine failed and are saying the engine needs replaced in order to fix the car I’ve had for 15 months… I’m still paying this car off and I have only driven it for less than 17,000 miles. It is a 2016 GMC terrain that only has 91k miles, I truly hope GM makes this right seeing as so many have come with the same exact problem due to poor design and vehicle quality. My car has had regular oil changes and I check the oil every week because of the prior burning problem.

Driver side blind spot not longer works. When driving the blind spot indicator just stopped working a month ago and I didn't take notice until I almost hit another car. I contacted gmc about this issue as well and was also told there isn't any recall for this and it would have to be diagnosed by there mechanics. There were no other issues prior to this. Also the "shift to park" warning has been popping up for 3 days now when my car is in park. My car won't complete shut everything off until that warning is turned off. I called GMC of puyallup and was told only certain vin qualifies for the recall for the gmc 2019 acadia. That's absolutely ridiculous! I can't exit my vehicle until the car senor knows my vehicle is in park which is a major concern and safety issue because my home is on a slope.

My brakes are not working properly. I can be backing up and put my foot on the brake. My truck will keep moving until I apply a lot of pressure on the brake pedal. I can be backing up and my truck will automatically brake and stop moving. I have to cut the truck off, start it back up for it to move. I was in a stand still traffic jam and braking a lot and my truck did stop it keep rolling. Sometimes when I apply the brake it slides.. This is the third time I have put it in the shop. I changed the brakes, brake sensor and replaced tires. I am scared to drive it. My truck is currently in the shop now for the brakes. please help.
