Sorry that you've had this occur. It's a module replacement rather than a cell replacement. A reasonably large piece. We haven't seen enough of these to have a large enough sample size for a decent estimate of the time, and I doubt your dealer has either. The failure rate for the cells (not the module) is about two per million. I suspect he just tossed out an estimate far enough out to set your expectations. Did you get a loaner?
HV Traction Battery Replacement Lead Time
Hi Guys,
Just wanted to see what kind of lead time people experienced when having their HV traction battery replaced in the past. About a week ago, my 2013 volt threw DTC P1E00 and P0BBE for the second time. I brought it to the dealer for investigation and they found that 1 of the 3 HV cells had failed and a second was showing low numbers. My service adviser stated that in the past, it is not uncommon for it to take up to 4 weeks to obtain a replacement cell. Currently my car is pending a response from GM on whether they will replace the defective cells or the entire battery pack. I was curious to see if anyone else has experienced this issue and what the time to repair was.

At 2 cell (cell not module) failures per 2M cells, that's 2 cell failures per 10K Volts or one failure per 5K Volts. That would suggest the dealer has sold at least 20K first generation Volts, which would be about 20% of all first generation Volts sold. That would likely be several hundred percent of all first generation Volts sold in Florida.My adviser stated that they have done 1 module replacement per month for the past 4 months and that my car would be the first with 2 bad modules. I do have a loaner currently but have not received any definitive time frame for the repair. I'm hoping to hear something from the SA today.
Maybe he's talking about something else related to the battery pack.
There are more Volt owners on this forum than people in the town and I don't think we've seen that many battery assembly replacements.Per the GM at my local ( tiny <20k people town ) Chevy dealer, they've bought back 7 volts including the GM's wife volt. They've replaced 21 battery cell packs and replaced 7 entire HV battery assemblies.
They also had to repair 9 gen2 volts with the wiring fault when the battery shorted and blew the fuse. There's apparently a lot of "Friday" volts out there.
