GMC Complaints

The contact called on behalf of a Fire Department that owns a 2011 GMC Sierra 2500. The contact stated that while the Fire Department technician was performing a routine maintenance on the vehicle, the technician became aware that the sub frame was rusted with a hole in the sub frame. The vehicle was taken to the dealer, where it was determined that the sub frame needed to be replaced. The vehicle was not repaired. The contact related the failure to TSB Number: 19-NA-255. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 29,252.

The headlights while driving will flicker completely off. This happens during the daylight lights are on and at night when main headlights are on. This is very dangerous and concerning while driving at night when I have to drive on country roads where the headlights are vital. This issue also creates unnecessary confusion with other drivers as they are under impression I'm flashing my lights at them.

I have a 2016 GMC 1500 Sierra Denali and experiencing a very scary problem that has suddenly developed with this vehicle. As I am parking or in a slow turn, the vehicle completely looses all power [engine, electronics, brakes, etc..] and the steering wheel jerks out of my hands and then a second or 2 later it comes back on and then repeated 2 more times as I was attempting to park. I had this happen while turning into a parking spot at the store. Then the next day it did it a again as I was turning into a different parking lot. I loose complete control of the vehicle. I have been lucky not to hit another vehicle, more specifically a person. I decided to park the vehicle at home and not drive it until I get GMC service to diagnose. I have an appointment at a dealership to diagnose the problem on 08-15-204 at "Chevrolet Buck GMC of Puyallup Inc.". I did some research on the internet and found a site where others have experienced the same problem. I looked for recalls yet none are concerning my vehicle, however I did find a recall# N202325410 that fits the entire issue for some earlier vehicles. Same exact problem. Something to do with the steering column electrical harness. Please advise what recourse I have?

Bought vehicle used/as is from dealer about a month after air bag recall announced in 2023. Found out it is apparently illegal to sell a vehicle with an open recall. Dealer did not disclose the recall and I did not research unfortunately. It's been over a year now since air bag was recalled and still no fix and I live in a very hot state. Should never take this long to fix something so dangerous - FATAL. Lives are possibly at stake!!! Also had to replace temp sensor which cost about $1,000. A/C wasn't working properly. Mechanic said they had to replace the temp sensor. Research shows this is a known issue. Also have had to replace O2 sensors and might have catalytic convertor issue.

Shift to park sign appears and doesn’t disappear until I turn and off the car multiple times. It’s been retuning problem for the past two months.

Headlights flicker every couple of minutes. Very concerning driving at night. Incoming traffic thinks I’m flashing them. Not good these days. Contacted dealer. They are aware there is a problem. They stated that GM has not come up with a fix yet. To me that answer is unacceptable.
