Hi all!

I really hope someone can help me out. I have just bought a damaged 2017 volt (picture attached). Damage took place to the driver side of the car, a lot of body work needs to be done. Pretty much all of the airbags deployed, except the dash one. Weird thing is that when I scanned the car with a scanner, it only showed fault codes in the airbag control module, but the engine light is ON. I needed to get rid of the airbag fault codes, so I used resistors to temporarily close the airbag connectors, erased air bag codes, and re-scanned the car again. My scanner showed no fault code in any of the modules, but the check engine light was still ON... What the hell!?!. When I start the car, and shift to any gear, the car doesnt drive and it says *action required - shift to park*

Does anyone has any idea what the problem could be?
Any help is appreciate! Thank you,

Andrey

I'm no expert but if it is 2017, it is still under warranty no? Can't you just tow it to a dealer and let them fix it?

If it was declared totaled all warranties, including the EV specific warranties, are void.

For OP, the most likely culprit is a bad gear shift position sensor. But if you're trying to restore this car you need to get yourself an ODBII scanner to actually read the codes.

2017 Volt recall for Shift to Park - GM Program #: N162060520
https://recalls.gm.ca/#/?vin=1G1RA6S...vels=566135029

Just got this recall in my monthly email today.

"Program Title:

No Start or Loss of Propulsion - Expires 9/30/19

Program Description:

On certain 2017 model year Chevrolet Volt vehicles, the high voltage interlock connector behind the high voltage battery disconnect relay fuse block cover may be susceptible to becoming recessed back into the high voltage battery disconnect relay assembly. This may cause an electrical disconnect which could result in a loss of vehicle propulsion and/or a no start condition. The malfunction indicator lamp may be illuminated and DTC P0A0C – “high voltage system inter-lock circuit low” may be set. A “Shift To Park” message may also be displayed. Additionally, a subset of these vehicles may have a condition in which the 15A fuse in the high voltage battery disconnect relay may prematurely open. The open fuse may prevent the low voltage battery from being charged by the 14v DC power module. If this were to occur, the vehicle will provide warning to the driver and eventually lose electrical power. Once power is drained from the 12 volt battery, the vehicle may lose propulsion and will not start.

Repair Description:

Reprogram the hybrid powertrain control module 2; and if applicable, replace the 15 amp high voltage battery disconnect relay fuse."

I wonder if this will also apply to 2017 Malibu Hybrids. Mine just went "shift to park" while on an extended road trip and yes, we're stranded out of state. We were driving on the highway at the time and the drive just quit, triggering the S-T-P warning. As a possibly-related item, I've been regularly monitoring the 12V system voltage (Hybrids have this ability in the scrollable display by the speedo). When the car was new, the voltage would float around the 12.6-13.8 range...about what you'd expect. Gradually though, that range has been creeping upward...so much so that the last couple of months it has been staying fairly steadily in the 15-15.5 range. I kept telling my dealer's techs about it, but they insisted that it was testing out normal. After the first day of diagnosis, the tech at the dealer where the car was towed is saying that there's more going on here than just a bad 12V battery. I think I'll flash this recall number for the Volt at him and see if it helps the process along. Thanks for posting this info!
