I am copying this from another complaint, because it is exactly the same issue. Vehicle was at highway speed when systems began to fail and vehicle abruptly lost acceleration. Warning lights and messages began to appear abruptly without warning. Rpm, and mph digital dial/ number jumped to 0 and back up to a random speed and then back down to 0. Accelerator pedal did not have any bearing on speed control. Uncontrolled stalling at highway speed without any warning. Vehicle was stopped on highway and parked. Vehicle maintained error codes. AAA contacted for tow.
Towed to dealer and serviced. 2017 Vehicle but has 40,000 miles and no longer under warranty. Technician was uncertain of problem and had to call GM Engineers. Dealer says fix was to reconnect wiring and reboot system. Seemed to work for awhile. Same issue on January 8 and January 13, 2019. Taking to Dealer again.
Very very very upsetting, especially since out of warranty period. (Error lights during incident: power steering warning light (steady on), tcs/stabilitrak warning light (steady on) and check engine light (steady on). Plus, vehicle service messages: service power steering and service stabilitrak. I have taken pictures of this).
