NHTSA complaint #11655369, filed 2025-04“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. Vehicle was built 06-26-2024 and has not been recalled so Chevy says I do not get the extended warranty on the replacement engine.”

NHTSA complaint #11713441, filed 2026-01“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. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. …”
NHTSA complaint #11681402, filed 2025-08“The dealer stated the 6.2L engine had a bearing failure. When driving on 12-24-24 to a family event the dash lights all lit up and the car shut off. I was barely able to put the Suburban into neutral to pull off to the side of the road. Once stopped, the Suburban wouldn't start or even go into neutral so I could push it further off the side. This is extremely dangerous. My entire family was in the car on a very busy day (Xmas eve) without the ability to move the car in any way. Even when the tow truck driver arrived, he stated there isn't a way to force it into neutral. …”
