When leaving work my truck would crank but not start. Started searching fixes on the internet. I found many people talking about a known issue with the fuel pump control module. Called the dealer and the dealer already knew of this issue in my year model truck. I purchased the fuel pump control module and fixed the problem. I purchased this module at full price because there is no recall on my VIN number. One week later a coworker had the same issue on his 2024 truck and his truck was covered under warranty.

I opened my passenger front door to load and the tailgate opens and closes by itself but doesnât and remains open. I physically shut the tailgate and it opened again by itself. I started my truck to see if it would stop. It didnât stop until I put my truck in reverse to back out of the garage. After I backed out and the tailgate stopped open. I closed it and the tailgate will not open by pressing the button on the tailgate. It will open if I use my key fob.

Pulling out from a stop sign, a loud bang came from the transmission, and rear wheels momentarily locked up then truck acted like it was in neutral. Truck was able to drift to side of road.

The mechanic called GM and asked if there was any financial assistance for this problem and they said no. He ordered a transmission through GM, and we had to pay for transmission upfront. The amount was 6627.05. Since then as we researched, we found out that GM has a Goodwill assistance…

My 10L1000 transmission had a catastrophic failure internally which caused it to rough shift, sudden down shifting, not want to shift into gear at all, and high engine rpm prior to roughly shifting. I took it to the Chevy dealers mechanic the very next business day, only to find out that from the mechanic that this is a common occurrence with Chevy transmissions in my truck and google also verified this to be a common problem. The mechanic from the Chevy dealership also stated that there was larger metal chunks than normal. My truck is available for inspection asap. The manufacturer and vin lookup contradicts the mechanic and google stating no issues or recalls for my transmission. After…
