This is exactly where I’m at. I took a trip to Florida in March with my wife and 3 kids (from Toronto, Ontario). About half way home the valvebody failed on my wife’s Tahoe. The valvebody was another item that suffered recall recently. In this case GM chose to reprogram the engine computer to only shift into 5th when it detected a failure. I’m it was way cheaper for GM to do this instead of replacing all the effected units. Anyway it failed 12 hours from home on a Saturday night. We ended up needing a hotel until Tuesday. Dealer of course is closed weekends. Monday afternoon they informed us that the valvebody was faulty and on a national back order. “May take months to get one”.
My wife and 2 kids got ride home with her parents who were still in Florida and cut their trip short to help. My son and I had to fly home.
About a month later GM got it the valvebody replaced so I flew down to pick it up. My wife missed 2 days of work and I have lost 4 days. GM told us they would reimburse us for the expenses. So far they have paid half and are now giving us the runaround about the rest. We are out thousands but GM sure saved by not being proactive and replacing all the effected parts.
I have a 2023 Trailboss with the same valvebody and also a 6.2 motor. I’m afraid to take it on any trips. My son has a go kart race 6 hours from home next month and I’m going to have to pay to transport his kart. I’m not confident my truck will be problem free and to be honest I can’t afford to pay the expenses if it fails and I’m towing g a trailer. It was a disaster with just the vehicle and no trailer.
FWIW I have held off posting this because GM had told us they would reimburse us but they haven’t come through.
My wife wants to trade both vehicles in for 2025 models but I’m not confident that would be any better. At least for us. If a pair of 2 year old vehicles aren’t reliable can you really expect that spending another $80,000 to $90,000 will?
