I've read a few of these instances, and here is another. Was asked to update software on Thursday. I clicked install now and came back to my truck after 30 minutes and it said installation successful. I started the truck, no problems and drove it all day. On Friday, the next day, went to store and it came up and asked for another update. I had time so I clicked install now and went into store. Came back after 30 minutes and found a dead truck. Nothing. had to use the physical key to unlock door. No dome light, no chime, nothing on dash. Completely dead. Called Chevrolet customer service and was on the phone for 1 hour with no one able to help me (waste of time). Finally called Road Side Assistance and they arranged a tow, which they had to drag my truck onto a flat bed since it wouldn't go into neutral. While waiting for the tow truck, I did take the negative terminal off the battery and waited 5 minutes to try to reset. Did this 3 different times. Did see a slight arc when reattaching the negative terminal (battery not completely dead). I tried jump starting the truck, but with cables and power attached, still did not have any electrical charge to the truck at all, no lights no dash, nothing.
Got truck to the dealer by 3:30 Friday afternoon, and was told they would get to it hopefully sometime Monday!
What I don't get is that GM is completely aware of this issue, I've seen articles from July of 2022 that describes this issue and what fix that GM put in place. I've had my vehicle to the dealer 4 times since July 2022 for other issues yet they never implemented any fix during those visits. I was not aware that when GM sends you an update and asks you to update your truck, that they might actually brick your vehicle. This is complete garbage for an automotive company!
My groceries were ruined, I couldn't use my truck to haul my boat all weekend, I wonder if they damaged my drive train while dragging my truck onto tow truck and I sit waiting for someone to call me and tell me what they can do to get my truck back. Are there any assurances that this won't happen again?
Needless to say, I'm not a satisfied Chevrolet customer at this point. This is my 5th Tahoe and probably my last!
It is a 2022 4x4 Tahoe.
