My 2017 Volt was involved in a front end collision. Immediately after the accident the vehicle did not start up. After it sat a few minutes it did start, but in ICE mode (I'm sure there is a real term for this, but this is what I call it.)

Does anyone know if the 2017 Volt has an automatic high voltage disconnect of some sort that may have been engaged by the collision? I am having trouble with the body shop getting it to a certified tech as they are clueless about how the Volt operates, telling me nothing is wrong... (it's a hybrid they run with the gas engine on :rolleyes:) Let's not even get in to that part.

Basically after the accident I no longer have a Volt that will operate in EV mode. I am working on disconnecting from the body shop with my insurance to take it to my dealer, but that is a whole process. Really I am just trying to gather if there is something seriously wrong or it just needs some sort of reset performed. The strange thing is the Volt is not displaying any warning messages. It just turns on and runs in ICE mode exclusively. Any ideas?

Thanks!

See your manual.

"If the vehicle is in a crash, the sensing system may shut down the high voltage system. When this occurs, the high voltage battery is
disconnected and the vehicle will not start. The SERVICE VEHICLE SOON message in the Driver Information Center (DIC) will be displayed. Before the vehicle can be operated again, it must be serviced at your dealer."

Or, maybe the hood open sensor just got messed up. (engine will run if hood is open)

There is a high voltage system software disable that happens after an accident. Your shop needs GM GDS2 to reset the high voltage inhibit. Ask Onstar to give you codes.

When a kamikaze deer took out my volt grill and radiator, my volt had the same issue. I basically had it towed to the dealership and the body shop fixed the damaged parts then they pushed it over to the service area shop to get everything working again.

Contact the nearest Chevy dealer and see if they can work directly with the body shop.
