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.

There is a vibration that is randomly felt. Over the last year I have replaced struts shocks control arm control arm bushings sway bar link sway bar link bushings tires twice and the vibration just keeps increasing to the point it's doing it now when I turn or take bends in the highway. There is now a flat spot in a tire feel when going it slower speeds to be added to the vibration that happens later on obviously related. This is either from my understanding going to be axle or driveshaft it's going to get looked at today since there's nothing left underneath to repair. This has ruined a pair tires I bought last year for $1,500 in September and probably well on its way to ruining the tires that I've just put on last week for $2,400. There is a hesitation a lack of response and a vibration. As far as the electrical goes it makes this very weird buzzing sound very randomly it's only happened about four times it's loud and it can't be explained. Also sometimes the radio and the AC just turns on and there's no key in the car and I've had the door open for a few minutes. Sometimes after turning it off he'll turn everything off but turn it all back on again no key in. Sometimes I can turn the stereo off and it makes a whistling buzzing sound and it's not even on. As far as any light indicators on the dash for any of this no never had a one. I have completely taken care of this vehicle with the transmission flush and will changes and everything that it's supposed to have and I put a lot of money in it since I've had it in a year but I shouldn't have to on 2019 and it's still experiencing the same problems and I have plenty of documentation. As far as date of occurrence it's been continual and random since I bought the truck in June of 2023 from a local dealership called Lokey

Transmission failure at ~90700 miles. Transmission failed while driving home from work on US-95 on 26 July 2023, placing myself and other drivers at risk of accident and injury due to vehicle unable to shift gears at higher speeds. This problem was confirmed by Sullivan Tire mechanics, who also spoke with mechanics at McLaughlin Chevrolet, who have stated that they have received vehicles for repair and replacement for the same mechanical failure. I am currently waiting on insurance to inspect this issue. The malfunction indicator light (MIL) did come on the information center at the same time the problem appeared.

Vehicle started shuttering then almost slamming from gears and eventually gave out at 97k - Vehicle is still in the shop right now, as I have no other vehicle

- New Sharon , ME, USA

The vehicle started jumping when switching gears or when accelerating from a stop. The drive shaft ended up separating from the transfer case, lost 3rd gear in the transmission, and blew the 8th cylinder in the motor. I am seeing that this is a common issue with the year, make, and model. Yet not all that were affected were actually included in the recall from 2020. We luckily were not in an accident from this incident however, this has cost us well over $10,000 in repairs. This issue needs to be addressed and GM needs to fix this problem. This could cause an accident.

- Orlando, FL, USA

The transmission jerks when shifting or just driving as you-??re accelerating and as you-??re at cruising speed, the transmission has a shutter that creates a vibration through the truck. My safety was put at risk as I did not know if the transmission was gonna fail as bad as the truck was shaking. The dealer reproduced the same problems that I was having. Said the fix was to change out transmission oil with the new transmission oil. Had to pay for a flush and filter at 56,000 miles. There were no warning lights coming on for the vehicle. Just the shattering of the transmission.

- San Tan Valley, AZ, USA

While traveling at a high rate of speed one of the Active fuel management lifters failed. This caused a misfire in one cylinder also damaging the cam shaft. The engine was stuttering and running very poorly at higher speed. Luckily it did not cause a complete engine failure and I was able to safely exit the highway and make it to a garage. The repairs totaled over $5900. This is a known problem with the AFM system and continues to be ignored by GM. Under different circumstances this could be potentially a very dangerous situation.

- Medical Lake, WA, USA

My 8 speed transmission jumps out of gear randomly. Sometimes when I'm trying to pass on a 2 lane road at which time I am forced to hit the brakes and get back in line behind the vehicle I was trying to pass. Or after have stopped at a stop light or stop sign and I'm attempting to make a turn. At which time it will sometimes jump out of gear causing me to be stuck in front of oncoming traffic. It's getting worse and the GM dealer can't do anything about it.
