truck has intermittent vibration at highway speeds and they are getting worse. The dealer just called and said the torque converter was shot. That seems to be a great deal of the power train complaints

The truck has a hard downshift and when stopping and starting again at a stop sign it will lunge forward sometimes.Also, when holding speed at 50-60 mph you can feel a slight shutter like the truck is not running correctly.The dealer flushed the transmission when I purchased the truck but the issue continued so I made an appointment with the service department on march 3,2023.They took the truck on a road test and did notice the hard downshift and noted that this is a normal characteristic of this transmission(this is not normal and is unsafe)and will not offer to repair it.It is now the end of July 2023 and the issue continues and no one seems to want to do anything about it.I am going to take it back again but I am probably going to get the same answer
The stabitrac system malfunctioned and went into low power mode while on the highway almost in an accident because of speed loss. The button to turn it off did nothing. Still unsure what caused this to malfunction but needs to be a way to override to maintain speed without power loss
I pulled off the dealer lot with 3 miles on the odometer, came to a stop sign and damn near smacked my face on the steering wheel due to a hard downshift from 2nd to 1st gear. Pulled back into the lot and was told that "I have to break it in". As I laughed in his face, I knew I messed up buying a GM product. 20 miles down the road, I start getting transmission shutter during light acceleration. Took it back to the dealer and they ended up changing the fluid. As I was coming to a stop to pull in my driveway, the transmission hard shifted and threw me past the driveway. Took it back in to hear "Yep, that is GM acceptable". I am now having transmission shutter so bad, the truck will barely accelerate at 30mph or faster. This truck is absolute junk and I tell everyone I know, not to buy a GM truck. I will never buy an American made truck until they are made in America again, as they are overpriced and don't last. I want my money back!
Transmission will jerk/run poorly between 30-50 mph. This will cause deteriorated driving conditions and inability to stay with other vehicles with acceleration. Service performed by Chevrolet to rebuild transmission due to pump failure which damaged clutch pack. Service was covered under powertrain warranty. Rebuilt transmission now slips out of 3 and 4 gear and allows for lose of acceleration control.

Transmission problems. Vibrates under acceleration and deacceleration. Occasionally won't shift gears up or down, slips or hesitation between shifts. Violet jerks at times. Dealer has done a fluid drain and flush at 20k miles, replaced torque converter at 54k miles. Goes back in again on Monday for the same complaints. I'm responsible for transporting my 5 year old daughter to and from school. Difficult to travel highway speeds when it decides to act up. Research shows many design flaws and thousands of compliments. I fear for my families safety when driving this. I'm told it's safe by dealership??
Ignition Key Cannot Be Removed and/ or Does Not Rotate to the Off Position. It started about three weeks ago and has gotten progressively worse. The engine turns off but the vehicle remains energized. Repeat start, gear cycling, steering wheel movement and holding the shifter detent randomly allows the key to be moved to the fully off position and removed. Reference GM bulletin PI1429B. Applies to my 2019 as well. Dealer did no research when I took it in and could not reproduce at time of inspection. Said it was out of warranty and without being able to reproduce, would have to have a tech try to reproduce then diagnose.
The vehicle shakes and shudders when accelerating and driving under normal conditions. The feeling is that of a very bumpy road or going over rumble strips. It is more evident in hot conditions and in more humid conditions. I have contacted several dealers, but none can offer or guarantee same day service, and none offer a loaner in case of a long repair. There have been no warning lights or service lights to the condition. The dealers do state that it is a known condition. The drive-ability is compromised, and it is very uncomfortable and unnerving to operate at this point.
I experianced tranmission chatter at around 12,000 miles. When I read that this is a common problem do to the wrong transmission fluid installed at the manufacturer. It was noted to have the service department change it to mobil 1 transmission fluid. After 11,000 more miles I now have the same chatter back. I fel that the service departments do not want to dive further into finding out what the problem is, cause it's under warrenty repair and the don't make any money off of your complaint. So that you come back and have to pay out of your pocket when your warrenty is up. This should be a recall matter in my eyes. Write all your coverns directly to GM and vent your anger with them. And if that doesn't work I'm going to the news crews to make it known.
Key gets stuck in ignition when shutting engine off leaving driver stranded and stuck with vehicle until key releases from ignition. No warning lights.
Since shortly after purchasing the vehicle new, I have experienced hard shifting, slipping when accelerating, also experience rough idle at times.I have had the torque converter replaced but I still ha E the problem. I've even had the service manager ride with me and he stated he experienced the lugging sensation, and said it's normal, they still did nothing to help me, and this is noted on their service record! this vehicle has been in the shop several times for the same issue, and I get the same answer as they find nothing wrong.
The truck shifts aggressively between 10 and 20 mph. Like it's slipping not engaging into second gear. Started noticing it at 16,000 miles and had the truck since brand new.
