NHTSA Complaint #11543060 — 2016 GMC SIERRA 1500

The transmission overheated due to a poorly manufactured torque converter which caused my truck to come to a sudden stop on the interstate nearly being struck by several semi tractor trailers leaving my family and I in a dangerous situation. Upon research the torque converter and the thermal bypass valve fail causing the transmission to overheat with no warning whatsoever. It massively blew smoke out of the tailpipe blocking all lanes of traffic, completely unable to see that I'm broke down and nearly caused several accidents. Police was not notified since no accident occurred. The transmission preformed as its supposed to. No hard shifts or slipping between gears. This needs to be addressed by the NHTSA and GM as it's a huge safety issue. With no warning light indicating the transmission is reaching critical heat levels and shutting down poses a risk in the event you're towing a trailer/camper (As I was). Or even worse happening to those who live where they drive up and down steep mountain grades.
