NHTSA Complaint #11633065 — 2014 CHEVROLET VOLT

Loss of propulsion. Vehicle will not start/move. If vehicle does turn on , it will not turn off. Vehicle has been having reduced propulsion issues for multiple years (taken to dealer many times) that dealership has refused to do a HV battery capacity test while under warranty, even after leaving with them for multiple months they claimed they could not replicate error. On day of pickup error presented itself and I showed service advisor and left vehicle for additional testing. Dealer provided explanation of reduced propulsion when in mountain mode as cause even though vehicle was not in mountain mode when error occurred. Dealer performed customer satisfaction GM Program # N172130462 update 11/2021 on HV system that stopped propulsion issues (mainly battery capacity concerns) until vehicle was out of warranty. Now vehicle will not turn on/move even though HV battery completely charged. Vehicle is essentially bricked at this point. Will be taking back to dealer 12/30/2024
