GMC Complaints

Started truck for 10-15 minutes with front and rear defrost on to remove ice from glass. Upon entering the truck, there was a smell of wiring/plastic burning. Smoke was coming from the bottom corner of the rear sliding window. I immediately shut off rear defrost and then shut my truck off. Then the driver side rear glass panel popped and shattered completely.

The rear lift gate on the Yukon xl has the automatic sensor underneath the trailer hitch that you can swing your foot under to open or close. Twice, while loading groceries, I have had it close on my head, and this time with concussion symptoms. This also happened to my elderly mother.

I was tboned January 9, 2023 the side impact airbags didn't deploy nor does it seem the seatbelts engaged. There were 2 side impacts to the passengers side ZERO airbags deployed. It WAS part of a recall AND recall work had been completed almost immediately in 2014 (GM website screenshots attached for your easy reference for the 2 recalls showing completed). YET, they STILL failed! NO indication they had an issue nor would fail when needed as they did. The driver of the other vehicle was seemingly going a high rate of speed when she failed to stop for the red light her direction and tboned me as I was traveling through an intersection for a green light my travel path. My vehicle was totaled, part of the total report attached indicated "Diagnose Airbags" as they didn't deploy. (Screenshots of a GM autobody shop estimate line item as well as CarFax report attached for your easy reference) Multiple injuries sustained, including a serious TBI.

Thermostat fails frequently leading to reduced steering assist and temp gauge drops to below cold while fan runs on high. Along with sporadic blackout on all interior screens/instrument panel.

Rear Sliding Glass window frame has cracked and allows water to enter the cab of the vehicle. Yes this is available for inspection. The water entering the cab of the vehicle can create mold from moisture build up if left untreated. I was able to have the dealer service center confirm the issue noted in [XXX] but they were unable to repair it as it is outside of warranty. I was able to have an independent 3rd party glass company confirm that it was indeed a manufacturers defect with a cracked housing and not an issue with sealant around the glass itself. No warning lamps or other indications other than water in the back seat of the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car started making strange noises in the rear portion and was not driving as it normally would. Proceeded to take the vehicle to a GMC service dept. and was told the rear differential is close to failure and is "shot" and needs to be replaced. The service representative advised us to not drive the vehicle because it is unsafe to operate. Upon investigating it appears there was a recall for 2021 Yukon's for this same issue however this VIN number was not included in the recall but it appears this is the same issue. My vehicle remains at the service center waiting for the "differential assembly" to be replaced but it is currently on backorder and we were given no time frame of when this will be resolved or when the parts will be available.

This recall has been open since May of 2023. So for 9 months I have patiently waited for a remedy to become available, they have yet to do this so the dealership will not fix my car.

The vehicle was crawling to a stop in preparation to park in front of my garage door. When I move my hand across the steering wheel, my hand must have come in contact with the toggle/scroll for the “resume speed” function of the cruise control. The vehicle abruptly began accelerating towards my house. I was able to press the brake pedal to deactivate and stop the vehicle safely. I note that in the past week, perhaps even two, the cruise control has not been used. The vehicle is driven 2-4 trips a day.

The contact owns a 2021 GMC Canyon. The contact stated while driving 6 MPH and going over a speed bump, the contact heard an abnormal knocking sound emanating from the driver’s side suspension. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the upper control arm was striking the suspension spring. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 47,000.

Riders with long hair is getting caught in the "DENALI" emblem embedded in the seat back of the front seats. This has been addressed with a GMC dealer and they stated the seat emblem is within specs as they put it. This is noted on the attached work order regarding this
