The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle would hesitate and jerk upon acceleration without warning. The contact also stated that while driving at an unknown speed, the vehicle stalled with the check engine warning light illuminated on the instrument panel. The contact had taken the vehicle to a dealer and was informed that there was a service bulletin that was linked to the failure. Moisture could enter the vehicle through the headlights and cause the electrical and transmission failures the contact was experiencing. The contact was given an estimate for the repair.

GM issued a recall notice on July 1, 2021, regarding the rear curtain airbags in my Sierra. To this date (12/27/21), they have still not provided an ETA for getting this remedied. I called the dealership in September, to which they stated it would be another month before they could address it. I am wanting to be proactive to get this issue remedied, but the delay is unacceptable. I am escalating this to get some traction.

I was hit broad side, by driver running red light. He was doing over 50 MPH I was hit left side forward of left door. My steering wheel airbag did not deploy fully. The crash caused only the steering wheel bag to deploy but it only came out maybe half way, it smoldered so bad I panicked seeing all the smoke and had to crawl out of my truck after kicking open the passenger door because the nose of the truck is racked to the right the passenger door would not open. Other car had full airbag deployed, all curtains and steering wheel

Hello, I am driving a 2014 Sierra truck with 17,761 miles, my father’s work truck. The first week I had No problems, the 2nd week the Trailer Brake warning came on relentlessly. New truck, scary Warning sign! I took it to GMC to dislocate trailer brake, they sold me a $340 trailer brake control switch. Upon my return to where I live a loud sound came from when I was idling to wait for construction to accelerating. I noticed once I got home, my back wheels were hot and a burning smell! I hate when you take your car in for one warning sign and you get something so much worst and you paid outrageously for that! Karma!

The component that malfunctioned is the vehicle braking system at slow speeds. I first experienced the problem at a restaurant drive thru line. After several stops as the line advanced, the braking system failed (extremely hard pedal) and car kept advancing and if someone would have been directly in front of me ( at a normal distance for a drive thru ) I would have made contact with them at a slow speed. I checked with my dealer the next day and they said that there were no reported problems for this issue on my vehicle. No warning lamps or messages present but it seems to me to be similar to the recall ( N192268490 ) as it only happens at slow speed with repeated application of the brake. There were no symptoms of the problem prior to this incident and it took me completely by surprise. I took the vehicle in to a service facility and they test drove it and said that they did not recreate the failure but I believe that they didn't try repeated braking at slow speed as I requested. I feel that there is a problem and that it only shows up during the aforementioned driving conditions. I have checked your website and the manufacturers and my truck VIN doesn't show up for their computer reprogramming recall but think that maybe it should.

While driving Truck was setting Cruise Control at approx 100km/hr. The cruise would set but at approx 70km/hr. Tried to set multiple time throughout the trip but no change. Recorded video and sent to dealer. They brought truck in to check it out, but said that since they can't duplicate the problem they cannot diagnose it. This has happened multiple times and have recorded video each time. Again dealer said they can't do anything unless they see it themselves.

I turned on my rear defroster. I smelled electrical burning and rear window shattered with my 6 month old in the back seat in her car seat. GM states there is a recall which can be referenced as N192220470. Speaking with customer service and dealership the recall is VIN specific and my vehicle is not included in the recall even though the year and make is listed in the recall. Very dangerous, especially when there are passengers in the back seat of the vehicle
