2012 Chevrolet Volt. About 11 months ago I received a software update to my Volt. A few days ago, my car refused to charge and produced the message, “Service High Voltage Charging System” with the diagnostic codes of P1E00, P0AA6 and P1FFF.
I took the car to Priority Chevrolet in Chesapeake, Virginia, and was hoping the issue would be associated with a service bulletin or covered under my GM Financial Extended Protection Plan (platinum version), however it wasn’t. It cost me $300 and the dealership was unable to tell me the root cause of the issue, which appears to be a software defect. The dealership noted that a software defect existed in the cars software and that this software defect would falsely detect a coolant issue and prevent the car from being charged. Apparently in July of this year, a notice was released from Chevrolet about this issue and that a software update was available to resolve it. The issue however didn’t impact my car until October of this year. My car doesn’t have a coolant issue or anything materially wrong with it. The notes from the dealership state, “P1E00, P0AA6, P1FFF stored in HPCM2 and BECM. Found PIC5920G. OHM readings in data list show good. Checked drain for hybrid battery, no coolant in system. Reprogrammed HPCM2 and BECM modules. Codes cleared. Coded did not return. Plugged car into to verify charging.”. In short, I was charged $300 for a known software defect when nothing was wrong with my car.
Has anyone else experienced this with their out of warranty Gen 1 Volt and had better luck with it being covered by a service bulletin, recall or other means?
