2022 GMC Sierra 1500 power train problems

“This report shows 4 more new attempts to repair the drop in power, bucking, surging, and lurching that my truck has been doing since May 2026, after the L87 Engine replacement. This issue has caused me to come very close to rear ending a few vehicles, including a Deer Park police officer. It has caused me to run through red lights unexpectedly. The vehicle has had a case open with GM Corp. Customer Care, Case(s) 95259917 (OLD), Case # 108994166 current case (Phone, Instagram). The problems are dangerous because the truck can begin shutting down and feel as if its stopping due to being stuck between gears or maybe torque converter. It happens on the highway at different speeds. It happens in city, stop and go traffic. The lunging forward comes into play with no prior warning. No lights, no messages on the instrument cluster. The dealer had me come in and drive the vehicle to show one of the managers what is happening while I am commuting. It has been confirmed EVERYTIME I was told there is no problem. I am attaching the latest work orders related to the issues after the engine replacement. For the past 6 months this truck is in the shop or stuck in my driveway…”

“The Fuel pump modular system failed leaving me unable to start the vehicle and left me stranded in the [XXX] heat for hours. The vehicle only has 57k miles. There was a recall for this specific issue for many GM vehicles but not mine. There was no warning! It has been towed to Sheehan Buick in [XXX] and diagnosed as the Fuel pump Modular system but I am being told it is not covered under the recall.”

“Transmission failed at about 40 MPH, coasted to the side of the road and wheels locked up. No warning lights even after the failure. GM dealership inspected and confirmed it is the common valve body failure on GM trucks but my truck is not covered on recall. It is sitting at dealer waiting for a decision. No warning, the dealer changed the transmission fluid and filter 4000 miles before.”

“After numerous attempts getting GM to finally look at why my vehicle because after the L87 engine swap, which failed after the Pico test and oil, oil filter, and oil cap change my truck has been dangerous to drive. It falls on its face when taking off or driving. It acts as if something is holding the truck back. It takes more throttle to get it moving. Then in traffic while moving it randomly lunges forward very quickly as if I have the gas pedal to the floor. I came very close to rear ending a Deer Park police vehicle. They told me to get my own alternate transportation and they would then look at it. I had to go out and get a rental car. I had no choice. I explained due to my HIGH medical bills following a cancer diagnosis, I could not afford a rental and my appointments. They basically told me come see them when i can make my arrangements. So, i rented a car, took the truck in, four days later i was told that the problem was my ADAS camera. I told them it worked fine before yall had it 3 months waiting on an engine. They told me I would have to pay around 1000 dollars to have my truck repaired. Even though it was clearly something they did. I made…”
