NHTSA Complaint #11514125 — 2017 CHEVROLET CAMARO

My vehicle dies while going 60 MPH or at red lights, creating a dangerous situation in traffic or on the highway. At times when yielding it feels like I've been hit by another vehicle from behind, the transmission does not downshift normally, and the TSB (see attached) proves that General Motors knew about this issue and did not notify customers or recall the vehicle for repairs. I have 2 issues with my vehicle and both issues remain unresolved even after utilizing the power train warranty. My vehicle was taken to the dealership for repairs multiple times, the "check engine" light was on the vehicle, no one checked it, and General Motors did not honor its Power Train Warranty Obligations, "the defects remain unresolved". My vehicle is dangerous to operate, I have tried working with General Motors to arrive at a solution, "But I should not be forced pay additional expense for issues General Motors knew about a, issued TSB's warning dealerships, and made no effort to notify customers. I am reporting this issue to the NTSB before providing a 30 day Notice of Intent to sue, to General Motors
