Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I received a p0747 and p0700 transmission codes on my GMC sierra 3500. It would not engage above 3rd gear and I almost was rear ended by a Semi truck because I was unable to speed up. The vehicle CEL turned on and Engine power reduced notification appeared on my cluster. Engine RPMS were at 2800 rpm and my speed limit would not go past ~40mph. I currently have my vehicle being inspected by the local dealership. The vehicle currently has ~19,300 miles”
NHTSA complaint #11581689, filed 2024-04“Transmission is locking up and making rear wheels violently shake on the highway at high speeds. There is a TSB for the trans valve body on 2020-2022 but it's doing the same for my year and every year with the new 10 speed Allison. It will put your vehicle in power reduce mode as well. I've had a 2020 do it and now my 2023. GM said there is no issue unless they can duplicate it and it does it randomly. So ridiculous for a $90k truck to have issues and then not be able to help.”
NHTSA complaint #11635594, filed 2025-01“Formal Complaint Against General Motors and Dealership – Ongoing Warranty Issue and Vehicle Inoperability To Whom It May Concern, I am writing to formally escalate a serious and unresolved issue regarding my vehicle, and the lack of meaningful action taken by both General Motors (GM) and an authorized dealership. My case is not isolated, it mirrors the experience of thousands of other GM customers facing the same known mechanical defect, as widely documented in online forums and communities. …”
NHTSA complaint #11664215, filed 2025-06“My rear wheels randomly lock up and truck violently shakes. It does it randomly in very long trips so GM and every dealer I've brought it to just says that they cant help me because they cant get it to replicate. Had the same issue with my 2020 and it has an open recall for the exact same thing. This is very dangerous and is going to get someone hurt one day if gm isn't help responsible and fixed their valve body failures for ALL of the 10L1000 L5Ps. Not just 2020-2022....it's ALL OF THEM. 2020-2025!!!”
NHTSA complaint #11683027, filed 2025-08“We were traveling to our cabin in Southern Utah when the Transmission Control Solenoid Valve stuck in an on position. We were unable to accelerate more than 55 miles per hour. We stopped in St. George and went to the Chevy dealer for a fix. We were told that they could not get to our vehicle for 2 weeks AND the part is on national back order for 6 weeks. Clearly if it is on national back order, this is a major problem in GM trucks. Our truck is still under warranty and Chevy would not help. We were 130 miles away from home. …”
