NHTSA Complaint #11578545 — 2017 CHEVROLET VOLT

On [XXX] my 2017 Chevrolet Volt with just 24,000 miles on it suddenly jerked/lost power/revved up while on the highway while using the gas engine--frightening/dangerous -- and continued to do that until I got to my destination. The error read "reduced propulsion". I was afraid of pulling off the highway for fear the car wouldn't restart and I had my 91 yr old mother in the car so we bucked along in the slow lane, the car revving fast, then losing power. It was very frightening and i proceeded with the flashers on. Took car to dealership balise in warwick ri. Tech said it was a bad EGR valve. They told me that GM would cover the repair under warranty but the part was on backorder. I opted to leave the car at the dealership hoping for the best but they said another customer had been waiting since September. They told me to take the car home, but i didnt feel the car was safe to drive. Web search reveals this is a common problem and people are waiting all over the U.S. for this part for over a year. Subsequent phone calls revealed that the part may or may not be manufactured ever again, and the dealership suggested I buy a refurbished part on ebay and have it installed at a local repair shop at my cost --- but that would null the warranty, and seemed risky to me. I asked the dealership to buy my car and they offered me $5k less than fair market value-so I declined. Opened a case at GM and they also had no answer, and offered to give me "points" to buy another GM car. Havent had use of the car since because I'm afraid to drive it with the car revving forward and at the next moment losing power. My car has been sitting in the dealer's lot for over 3 months, while I continue to pay registration, insurance and watch the value of the vehicle decline. Dangerous and GM will not buyback or rectify!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
