Friend has a 2012 Volt that was not charging...She took to dealership and has been repaired. Seems like this should be covered under the Voltec warranty. She called GM and they called the dealership. Dealership stated this was more of an electrical problem so she was charged.

Any help would be appreciated. Below are actual words on ticket.

Codes P1E00, POAA6, P1FFF, and B3205 checked for loss of coolant pulled battery drain plug, no coolant loss, all full , checked to find buttlin DOC#4838351 for updated calibration on HPCM and EBEC
Tech: 14 -CL
Programed HPCM-2 Programmed EBEC programmed ECM C learned codes and test drove

She was charged $245 for this. Should this be covered under the Voltec Warranty she has 78k miles? Thanks in advance.

Aren't' the HPCM-2 and EBEC computer/controllers specific to the Voltec drivetrain? If so I think this should be a warranty item. The key here is that dealerships only get paid 60-70% of the "retail" pricing when they bill GM for warranty work.

Well, that is what I was thinking as well; I am hoping one of the moderators or a Volt Tech could chime in with a definitive answer.

The hybrid powertrain control module 2(HPCM2) and the battery energy control module (BECM) both should have been programmed for this issue and both are covered under the Voltec warranty.

Tell them to look up this bulletin.

Thank you thank you for this everyone, however I have a related question. My Volt is not charging, or if it does I have no idea how it just decides to?! So as to this bulletin I have a 2011, but it has a salvage title, what can I do how can I possibly fix this?

FYI, GM seems to be no longer wanting to cover this under warranty. The internal info my service rep sent me from Keyes Chevrolet shows Labor Op 5021400 and 5430940 Not clearly covered by the Voltec Warranty even though in the PI0961B Bulletin it is CLEAR. They are seemingly changing the warranty post purchase. I have escalated my claim.

They wouldn't cover it for me either. Ended up getting a discount at 250 to get it fixed. Had the TSB printed and escalated it with Chevy direct still couldn't get it fixed.

PIC5920G is mentioned on this GM 'internal' blog and states they are covered under the Voltec Warranty!!

The special labor operation listed in PIC5920G as well as normal programming updates for the HPCM2 and BECM are covered under the Voltec warranty period (8 years/100,000 miles, U.S., or 160,000 kilometers, Canada).
