Seat Belts
Filed Mar 23, 2026KS

I was driving down the highway at 70 mph, when there was a loud bang followed by a gun powder smell. My seatbelts went tight...hazard lights automatically came on...radio went dead...and the Airbag light came on. The pretensioners in both driver and passenger seats had deployed. I pulled over and shut the truck off, to get out and inspect it. There was no warning, and luckily I was composed enough to not wreck into anyone or anything. I see there have been a few similar incidents, so I'm glad this isn't just a solitary incident.

Air BagsCrash
Filed May 31, 2025OR

Air bags did not deploy when another vehicle hit truck on front passenger side at 35-40 mph

Seat Belts
Filed Jan 2, 2025NJ

I was driving in a parking structure at low speed when a loud bang went off inside the cab. The hazard lights went off, there was an acrid electrical smell, and fine dust was coming from the steering wheel area. I stopped the truck and got out to look for a collision, but there was none. When I restarted the truck, the air bag light came on and I noticed that the seatbelts were retracted and no longer functional. I was not injured, but I believe that if this had happened in traffic or on the highway, I and my passenger could have been seriously hurt. The vehicle was towed to the GMC dealership, where they identified an error with the module that sends a signal to the airbags and seatbelts to deploy. Prior to this occurrence, I had no indication that the airbag/seatbelt system was faulty or in need of service.

Wheels
Filed Oct 25, 2024MN

No accident happened as the wheel was never installed due to not meeting the load weight capacity rating of the vehicle. The wheel is marked max load 1150kg (2230 per axle) and the vehicle weight loading label shows the rear axle capacity at 2706kg. The wheel is also marked as SAE J2530 compliant but does not meet J2530 section 3.5 due to the low load capacity. These wheels are widely available in the aftermarket and list most of the 2000-2010 GM 2500HD/3500 pickups as the application but do not meet load capacity on any of them. Please note that the VIN is for a typical 2008 Sierra 2500HD pickup in a scrap yard. I do not own that vehicle. It is a weight label photo from Hollander parts finder on that pickup.

Engine and Engine Cooling › Exhaust System › Emission Control › Catalytic Convertor
Filed Sep 17, 2024151,071 milesNJ

The contact owns a 2008 GMC Sierra 1500.

The contact stated that while driving at an undisclosed speed, the contact turned on the A/C, and the vehicle started shaking abnormally. Additionally, the vehicle made abnormal sounds, jerked, and stalled while driving. The vehicle was taken back to the dealer, and there was smoke coming from under the hood. Upon inspection, the dealer discovered that the catalytic convertor was extremely hot and glowing red. The dealer determined that the exhaust system and catalytic convertor needed to be replaced. The vehicle was then towed to the residence. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 151,071.

Reading this record

Complaint volume is well above typical for a single model year.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.

Most recent recall on file: Feb 5, 2021. Source: NHTSA Office of Defects Investigation.
