What owners wrote
The contact owns a 2015 GMC Sierra 1500. The contact stated that while driving at approximately 45 mph, he observed a popping noise beneath him. The contact stopped the vehicle and observed smoke emanating from the front of the vehicle. The vehicle went into limp mode, lost power, and when the brake was depressed, the vehicle did not slow the vehicle down as intended. The contact stated that as he pulled into a parking lot to inspect the vehicle, he observed flames emanating from the hood.
While at low speed and at stops while turning the wheel the entire dash and engine cut off and come back on. The steering also locks up to a point of not turning either way. All incidents happened on a very smooth flat road. This put my life in danger on one occasion while turning on a highway where my entire truck shut off mid turn.I have video of this occurring on my phone if you would like to reach out to me for that. I believe this to be a stabiltrac issue, one of gmc's traction control branding things.
