Cold start after vehicle sits for a while vehicle shark bites and stutters. When you try and drive vehicle before it-€™s been warmed up significantly. It-€™s a safety concern because it feels very danger and could cause an accident. Alamo At caused my truck to stall out the other day with my children in it and a large accident. Dealership is dismissed my concern and says it-€™s normal gmc defects that I have to deal with. I will sue GMC if I have to.

The vehicle was in motion on a city street, when the vehicle completely powered off. The steering wheel locked. This occurred on 11/22/2020 and 11/23/2020. The following message is on my dashboard 'steering assist is reduced drive with care.'
