i have experienced the odd lurch forward after remote start. it's happened a handful of times since new. 6.2L sierra crew, mfg date 8/2018. it was more prevalent when new and hasn't happened in a while. about 3000 miles on it now.
so yeah, after a remote start i get in and as soon as i turn the key, the whole truck lurches forward. i do set my parking brake every time i stop. maybe the parking pawl didn't fully engage until the key was turned on again? not sure if that makes sense. it has only ever happened after a remote start.
anyone else ever experience this?
i do not have the shudder issue. other anomalies include a hesitation when shifting from first to second (only seems to be when cold though). the shift from first to second is also much firmer than other shifts.
