NHTSA Complaint #11437014 — 2017 CHEVROLET TAHOE

I was driving this vehicle in rush hour traffic and the check engine light came on and it suddenly lost power and wouldn't shift gears. I pulled off the road and placed the vehicle in park. At that moment I received an email from Chevy OnStar stating my transmission had a problem and to take it to the dealership. I had it towed to the dealer and was informed that the torque converted had failed and there were metal bits in the transmission fluid. The transmission had to be completely replaced to the tune of $6450.00. This vehicle has under 67K miles. There were no warnings prior to this incidence. This vehicle has been maintained at the prescribed GM service intervals.
