My 2017 Volt has been in the shop for a month waiting for the back ordered BECM The local dealer doesn't have an expected availability time yet either since the part is on a national back order. I'm also kind of sad cause its been a hot summer and my Volt spent 4 weeks in the hot Texas sun outside where it was towed to the dealer. The only mildly positive is that the part is covered under warranty; of course that doesn't include a rental or anything like that.

Coincidentally we had an order for a 2022 Bolt EUV premier for my wife, and they got a Bolt EUV that just had the battery replaced when the previous customer backed out. So this weekend we become owners of a brand new Bolt EUV. For now we're keeping my wife's old Mazda until the Volt comes back from the service shop. We were thinking the Volt would be the ideal road trip car since the Bolt super charger network is still pretty sparse here in central Texas.

Just curious what state your car was sold in when it was new? It's a bit unclear whether the Voltec warranty (which covers the battery and BECM) extends to 10 years/150k miles in any state other than California.

The BECM is covered outside of California. We're in Texas and I'm not sure what part of the warranty covers the BECM. My 2017 Volt will be 6 years old in December, so its past the standard 5 year warranty, but the BECM repair parts and labor will be covered when the replacement BECM finally arrives for my 2017 Volt that has been at the local Chevrolet service shop for ... too long.

Many owners say, that after BECM reprogramming the guessometer started to show less miles, so that's probably ok. You could estimate watching the numbers of kwh, used from a full charge to full discharge, and then kwh, used from the grid for a full charge.

My 2017 has about 13% battery range sitting in the hot Texas sun waiting for a BECM last summer; the car was towed Jul21 2022, and stayed outside in the hot sun until it was repaired and returned home Nov 1st over 3 months later. This was the hottest Austin Texas summer on record with many 105 degrees in July. The range new roughly 53 miles for a mix of city/hwy driving at 14.1kwh, and now its about 46 miles, 12.25kwh. Prior to the repair, the Volt battery had degraded and was down perhaps 6.5% from new, so the 3 1/2 months roughly doubled the battery degradation.

Personally, 46 miles on a full charge is plenty enough for my daily needs especially since we now also own a 2022 Bolt EUV with 250 miles of range. During the week, I drive the Volt to work, my wife drive's Bolt. In total, the Bolt gets much more of our annual driving miles even given the roughly one to two trips per year that's more convenient in the Volt due to the DCFC charging network limitations in Texas.
