GMC Complaints

I was driving my car December 10, 2023 when I was at a red light my truck completely shut down I could not reverse I could not put in drive I could not put in Park I could not switch gears. I didn’t know what happened. I had to call a tow truck to get me home once I got home I got my car towed to a shop. Before my car was towed I contacted OnStar. OnStar did a diagnosis on my car and it came back ECM which stands for electric control module. When my car was at the shop i got a tune up & the mechanic was able to start my car. Driving again on the date of December 15, 2023 it did it again and it said ECM. I was paranoid because I was on the expressway I had too get my car towed to the Dealership. This is the second time that my car has did this. I keep all maintenance up on my car. I’m not understanding what’s going on. I feel like it should be a recall on this issue. It was very dangerous both times that my car stopped. Now yet again I’m waiting to see what the problem is. This is definitely a safety recall issue. I have a 2018 Denali terrain with only 71,000 miles i keep up with oil changes and maintenance on my vehicle. Who do i contact about this concerning scary situation, Will it take for a person to die before this is is rectified. Someone please contact me or respond to this situation. So we can request for a recall on this serious matter

Like many other complaints..when your driving and accelerating it jerks and try’s to change gears ect. Most recent issue is the temperature sensor went out and my fan was running on full speed. Well I got it fixed and within 2 months it has gone out again! Lastly, the paint on the hood and roof. When I bought the dealership fixed the hood and yet again it’s failing again..

The contact owns a 2023 GMC Canyon. The contact stated that upon activating the defroster during cold winter weather, he became aware that the defroster failed to properly defrost the front windshield and that the windshield wipers failed to adequately remove ice debris, potentially compromising windshield visibility. After a visual inspection of the windshield, the contact observed that ice had damaged the windshield wipers. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The failure mileage was 3,000. The contact stated the vehicle was taken to the dealership on 12/14/23. They did a full check on the vehicle and could not fix the issue. The dealership also were unable to find any information about a potential fix from the manufacturer.

I was travelling south bound on the highway at 70 mph when out of no where the left rear tire failed. The tread peeled back like an alligator skin and tore apart the side of my truck and caused me to fishtail all over the highway. I was able to avoid colliding with other vehicles on the road and miraculously made it to the shoulder of the highway. The tire is a Goodyear Wrangler TrailRunner AT in a size LT275/65/R20. I still have the remaining parts of the tire. My vehicle is still under manufacturer warranty, but the GMC dealer turned me away and told me I had to deal with Goodyear directly. I reached out to Goodyear to file a claim for the tire failure and damages related to it. They have been ignoring me for over a week, so I have filed a claim with my insurance company to handle the damages. I'm currently waiting to get my truck into the shop for repairs. There were no indications of any issues with the tire. I had them rotated as recommended by the manufacturer and kept the tire pressure at the recommended levels through the dealer when my vehicle was serviced. The TPMS light came on as soon as the tire failed and lost pressure showing the vehicle tire pressure monitoring system was working properly when the tire failed.

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 contact stated that the manufacturer had exceeded a reasonable 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.

Major major frame and wheel well rust , ever one I see is exactly the same , I live in upstate ny and yes we use salt but I've done a lot of research and the problem is country wide , please do some things this isn't right , I'm not trying to get a new free truck , just not get screwed out of the one I have cause it will fail inspection soon

I received notice of the recall on the airbag of my vehicle. I contacted the dealership and was informed I should contact GMC if I was concerned for my safety. I contacted GMC, explained my case and now several months down the road and I am still driving a vehicle that could explode in my face, quite literally, if anything happens. Although I can control my driving actions, I cannot control others. And as I try to be safe, it does not always allow for that concern. I bought this vehicle for my grandchild, and I am still limiting the use with her in it and trying to use other vehicles to protect her. This has caused more issues for my family than it has been worth owning this vehicle and GMC was not willing to assist in any way!!

Transmission shakes constantly not just when shifting. Repair shop says this is not repairable and is a common issue in trucks like mine. 2016 GMC Sierra. Vibrations are significant enough to cause a safety issue. Getting worse with time.

This complaint is about General Motors not allowing their Dealer Marty's Chevrolet of Bourne Ma. to recalibrate the odometer and speedometer and other parameters in the computer to match new 18"wheels and tires. The truck was built and set up for 20" wheels from the Factory. The previous owner installed 22" wheels immediately after leasing the vehicle. They never adjusted the computer for this change and as a result the odometer reading read 28700 when I purchased it in August 2023. As a result the engine hours do not correlate to the low miles and the speedometer reading is incorrect. This truck has about 75 to 80 thousand actual miles. When Marty's installed the new wheels that I bought, GM refused to authorize the computer adjustments for the new wheels. GM previously required this adjustment, but no longer does it. This is a safety risk and actual fraud because of the inaccurate miles recorded. I hope you can require them to authorize this adjustment.Attached is an old instruction from GM to dealers for this wheel size change work order.
