Upon stepping on brakes, the car shifts into Neutral and says “press start Button again.” This happened to me 2x now.

Complete and sudden failure of the L87 V8 engine at 70 mph on the highway. Had to maneuver to the right shoulder and coast to a stop. Engine was seized and would not restart. Waited 4 hours on a dangerous highway for a tow truck which took the Chevy Suburban 200 miles to my home Chevrolet dealership. They have ordered a new engine but it is on backorder so no ETA.

I took my 2024 Chevrolet Suburban to get repairs associated with GM safety recall N252494000 - L87 Engine Loss of Propulsion. My vehicle "passed" the test, so the "correction" employed by GM is that "vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filer replacement, and an owner's manual insert." All of this was done free ...

I managed to coast into a parking lot. The engine light was on. I turned the vehicle off and waited about 5 minutes and turned it back on, The engine light remained. The first time this happe...

The vehicle only has ~39,000 miles on it and the transmission went out and the car is not drivable. The dealership said it is a faulty valve body and that the part is on national back order and could take 2 to 6 months or even longer to get the part before they can start work.

The engine light comes on and then the rpm's drop to 35 and a notification comes up that says "reduced acceleration. driving with caution". If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears.

This has happened multiple times, it doesn’t matter if I am going 40MPH or 60+MPH. I have taken it in and they say there is nothing they can do for the issue.
