“My 2006 Gmc Sierra 1500 4x4 crewcab was running idle as I was preparing to leave for camping trip. I was checking to insure all lights on vehicle and trailer were functioning properly before departing. I noticed upon departure that smoke was coming from inside the steering column. I turned off running lights and when I tried to turn off the vehicle I found that I could not as the key was froze/stuck in the on/run position. The cab of the vehicle was filling with smoke and I could not turn the vehicle off. …”
NHTSA complaint #10615072, filed 2014-07, 61,500 miles“The driver's side seat heater randomly comes on. If you turn it off it comes right back on again and cycles through the various heat settings. It creates a dangerous distraction in the florida heat. I've taken it to numerous dealers, none of which can fix it. I call GM and they won't even consider it until I take it back to a dealer saying they will only get involved if I have taken it to a dealer within the last 30 days. One dealer told me that was a lie, there is no 30 day requirement. This issue is more of a distraction than texting. …”
