Transmission slips, into 2nd i believe. Hard shifts, shuddering and shaking at intermittent speeds. Also missed shifts and dtc triggered in performance mode. Started happening last year, 2023, progressively becoming worse overtime. Last summer is when it didn't shift and set off multiple codes that had to be cleared to be able to operate normally. Dealership stated since codes had been cleared they couldn't do anything about it, so nothing was done. (I can still find the codes with my personal code tool)

I have several issues going on with my vehicle. The transmission keeps shuddering and the dealer says there is nothing wrong with it. I've documented over a dozen instances. It feels like you are going over rumble strips. Also the screen flickers bad making it difficult to see the backup camera. I have a dozen or more videos on this and the dealer says they can't reproduce the issue.

The truck has lifter failure leaving the Engine in Operatable at best you and you kids are stranded in 0% wether or broken down in the road. The other outcome is the Engine Explodes like a bomb when the internals let go from the failure. Lucky I was just left in the cold where I could have frozen to death. This happened at 70k miles but is happening to all the 19+ trucks with 5.3-6.2 the other problem is a transmission shudder making you barely able to keep control of the vehicle. You have had so many complaints here there have been several class action lawsuits yet nothing has been done why is Gm not held accountable?

Since approximately 30,000 miles I have been having issues with the transmission. I have taken my truck to x3 different dealerships. Tom Bell in Redlands, CA and Mark Christopher in Ontario, CA are the first two. Both of them have told me there wasn't a problem and reprommgrammed the computer for the trans. I tried working with the chevy advocate and they did nothing but give me the run around until my chevy warranty ran our at 60,000 miles. Now I am once again attempting to get the truck looked at by a chevy dealer and I have taken it today to Diamond Hills in Banning, CA. My extended warranty runs out in 3000 miles and they had me come in to have it evaluated and they said they wanted to service the transmission. So we will see what happens. I regularly take my truck to be serviced at firestone and my firestone rep has warned me my transmission is definitely going OUT! It is unfair how the everyday person if forced to eat the cost while chevy keeps making money and dodging their intentionally distributed problem trucks. Please advise on how to hold them accountable for their intentional malpractice. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

CEL for emissions evap circuit. Problem part is fuel pump control module. GM has recalled other vehicles over this part and has suggested its failed operation may cause the engine to stall due to the fuel pump shutting off. Currently my vehicles evap system is unable to vent fuel vapors to the engine which poses a safety risk if the pressure accumulates in the tank. I believe GM wasn-??t thorough in the recall and only recalled what was absolutely necessary. The part is on back order which points to how common this item fails.

We are experiencing Vehicle shuddering and or shaking when accelerating and Jerking while shifting the vehicle. Originally discussed with dealership during routine oil change and thought that it was possible connection with the auto stop/start so no further action taken. Problem has worsened to now affect ability to tow trailer and or use vehicle. Vehicle has already had engine replacement at 41k due to engine oil coolant line failure. Current mileage at 86k. We do not feel comfortable driving the vehicle at this time so it is parked awaiting service appt with dealership.

Transmission started slipping and shuddering on vehicle with only 72,000 miles. Took to the dealer and they diagnosed the transmission fluid and torque converter needed to be replaced. The vehicle experienced harsh shifting since new and is a safety issue due to delayed speed, slipping, and hard shifts. There is a class action lawsuit for this 8 speed transmission and GM refuses to fix it. I paid $3,000 out of pocket to have this fixed even though it-??s a known. Issue.

vehicle experiences a vibration or 'shudder' when accelerating and when maintaining a constant speed. The shudder is coming from the transmission. There could be a safety concern should the transmission fail during operation. The dealer has confirmed the problem and performed a fluid flush. However, the problem remains. No warning lights.

When pulling off or slowing down, there's hesitation, jerking, and kicking or slamming going in or out of gear. Was passing a vehicle one day and it started going, then lost acceleration. I put it to the floor, still no acceleration. My Abs/Traction light came on, the rear end started like bouncing, or something with traction. As I pulled over, the abs/traction light went off. A few times we complained about it, they looked at it, but said they couldn't find nothing wrong with it. It's still happening and it is dangerous. I have a 17 yr old Autistic son, I drive him everyday to school, almost 4 hrs a day. We bought the truck cause we needed something reliable. But now that our warranty is up we can't afford to get it fixed. They made sure to let us know about our warranty was out. But at the time they looked at it, we had warranty. But when it came to get it looked at it would take days, and we needed a rental but they never had one, so we would have to wait till they had an opening.
