BECM (battery energy control module) issues and inconvenience — class action?

I'm not an attorney, but given the repeated stories and similarities in our experiences, I'd like to see what the pulse may be for some sort of class action.

I specifically shopped for a GM Certified car in Nov. 2021 because I believed the warranty would be important. Three months later, the BECM was diagnosed as bad. The warranty covers repairs, but I've been waiting more than a month with no ETA on a part. Some online suppliers seem to have the part in stock, but the dealer says they can't use a part that's purchased elsewhere. The warranty provides courtesy transportation, but the dealer claims there are no loaners. They won't return my calls. I complained to GM, and they said they would look into it, but I haven't heard anything back yet.

The 2018 warranty explicitly states: "A part not being available within 10 days or a repair not being completed within 30 days constitutes a significant inconvenience."

If anyone else who has not received adequate service when their battery energy control module failed would be interested in looking into a class action, please PM me or email me (zimmerdale at yahoo dot com) with your name, phone number and/or email, your state, year of your Volt, and a brief overview of your experience, I'll try to compile a summary for circulation to see whether anything can come of this.

I wish more people would report the BECM issue on the NTHSA complaint board - especially if it's causing a clear safety issue like suddenly stopping the car. I recently did a search on the board and found 9 hits for "BECM" or "battery energy" for 2017 Volts, and 0 for any other year (2016-19). But from this forum and Reddit it seems the problem is much more widespread. The government is not going to force a recall unless they have evidence that it's a serious and common safety issue.

To make it easy, here is the link to do so. Approximately 100,000 Volts were manufactured between 2016-2019.
