In January, my disabled wife's Chevy Volt was vandalised. Due to Covid-19, it eventually went to the repair garage in August. We delivered a fully working car, with damage to the bodywork, to the garage. After about three weeks the garage notified us that the car was ready for collection, however, they told us that it has a "Service High Voltage Charging System" notification was showing, and it couldn't be driven on electricity. The man said: "at least it could still be driven on petrol!"
The repair involved removing the n/s front wing and door, and knocking out some dents, plus a few bits of trim etc.. This was all done during the heat wave in August. We refused to take back a broken car, so the garage had an electrical test run on it, that showed the following:
Engine Control Module - P1E00 00 - Hybrid Powertrain Control Module 2 Request MIL Illumination - Failed
Hybrid Powertrain Control Module 2 - P0AA6 00 - Hybrid/EV Battery Voltage System Isolation Lost - Failed
Hybrid Powertrain Control Module 2 - P1FFF 00 - System Isolation / Coolant Level Sensor Fault - Hybrid/EV Battery Charging System Disabled - Passes and Failed
After reading the forums, they said it needs a new Coolant Level Sensor, and this is a common fault with these cars and not their responsibility. Therefore, it's a coincidence and nothing to do with them. The insurance company keep saying it did not happen as a result of the vandalism, which it didn't, it drove perfectly when we handed it to the repair garage. The insurance company got two of their engineers to look into the situation, who have been told by the garage that the forums say it is a common fault, consequently they have concluded that it is a common fault and nothing to do with them. I was not notified of the engineers visit to the garage and therefore not able to speak to them, they only received comments from the garage. No one told them that heat and vibration can cause this problem. This is all very one sided. We doubt whether they were even EV engineers.
If you put an electric car into a garage that is in good working order, it should surely come back to you in the same condition and not broken? This is totally unacceptable.
Finally, I understand this warning message can occur by disconnecting the main drive battery or by damaging the charging port. I would very much appreciate your opinions as we are now desperate, our broken car is still in the garage, and we are at a dead end with both the garage and the insurance company. Thanks for your help. Incidentally, we did not choose this garage, it was one of the insurance company's garages. We also informed the insurance company that we were concerned about an EV going to a garage that was not qualified to do electrical repairs. We also stated that we would hold them responsible for the electrics, as we were concerned about this situation. We were assured it would be fine.
