My baby is dead. It will not Start/Charge and the BECM is to blame. Dealer said they've had other BECMs on order for over six months but the chip shortage has caused a nationwide backorder.

As I need a car, what are my options? GM said it's not eligible for buyback as the bumper to bumper expired. Sell it to the dealer? Just suck it up and wait?
Mine is dead also. Please call the NHTSA at 888-327-4236 because they do not know how many of these BECMs have failed and it is a safety hazard because the car can stop suddenly in traffic. There is no recall yet because the NHTSA does not know how many have failed because people are not reporting it to them.

Is this still happening a lot? Is there a precursor to a BECM failure? Any warning sign?
The first thing I saw was a check engine light and I took the car to AutoZone and they read the computer and it came out with a description that said, "battery energy control module lost communication with hybridEV battery interface control module 3". After I left the AutoZone, the check engine light went off. But at the time I was not aware of the BECM failures so I thought the car just needed a new battery because the battery was old. So I had the battery changed and the vehicle started to act normally so I had no clue that my car had a serious problem. I started driving it again and that's when I stopped at the Post Office and the computer just went nuts and the car, although it was in drive, started sliding backwards. It wouldn't go, it wouldn't go forward, it wouldn't do anything. I panicked after the tow truck didn't show up, and I was stuck, and I started to pray, and then the car started going and acting normal but it was stuck in mountain mode, and I got it home, and after that it continued to behave strangely whenever I would start it and it would refuse to charge and it started acting completely crazy so I stopped driving it and right now it is parked because I'm not sure what to do about it. The cost of the repair, since it is not under warranty, is somewhere above $3,000 according to things I've seen online. Plus I was told the price of the part has gone up, and when I asked how much, I was told "it's really really expensive." The gentleman never did tell me the price. So I haven't had the car towed to the closest Chevy dealership, which is about 50 mi away, to have the car formally diagnosed because I'm concerned about the potentially high cost of repairing it.

If anyone has this problem repaired and it's not under warranty, would you please tell me how much it actually costs to have it fixed? Fortunately, I have an old car that still runs, so I'm driving it.

Thank you.

According to a dealer I talked to, in California only, the BECM is covered by the 150,000 mile Voltec warranty because it is an emissions issue. My car is sitting at the dealership waiting for the part to be manufactured.
