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.

Vehicle is in the shop getting repaired under warranty for a defective transmission valve body. Chevrolet is not able to get the part and it has been two weeks. Almost had an accident on trying to come to a stop and the transmission failed.

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.

The pickup shifts violently in and out of overdrive and than into second and than overdrive all while driving down the road at 55 mph and the rear end locks the tires up some times and the whole truck vibrates really and this power Tran problem is getting worse everyone I drive it and it's not safe to have any passengers or my kids in it anymore and it feels like the transmission is going to disintegrate at any moment because and if it does the transmission is going to lock up and than its going to cause a car accident..PLEASE FIX THIS PROBLEM BEFORE THIS TRUCK CAUSES A ACCIDENT BECAUSE OF A MANUFACTURING PROBLEM..IM JUST THINKING ABOUT MY KIDS SAFETY AND OTHER FAMILIES SAFETY ON THE ROAD...FROM A CONCERN PARENT..

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while the transmission was shifted into park(P), the contact turned off the vehicle; however, the instrument panel and radio remained operational. The contact restarted and then turned off the vehicle a second time to correct the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 70,000.

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.

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.

So my Silverado is having the same issues as many other Silverado owners. I originally had the vehicle in for service on a transmission issue, which is also another problem these vehicles are having. As for the engine issue I have experienced the vehicle stalling out after running rough, primarily after the vehicle has been running for a while. In addition, there are times when I am driving at highway speeds and the vehicle seems to shudder and shake. I thought OK maybe it's the wheel balance or alignment so I took it in for the wheel balance and the alignment and it still is doing the same thing. So at this point I had the spark plugs, wires and coil packs replaced. Still having the same issue. In addition to this I had the vehicle in for first time transmission hard shifting at around 20k miles. The technician took the vehicle for a drive and stated that there was an issue and that the computer reset should eliminate the problem. It didn't. So I dealt with this multiple times, bringing the vehicle to service for diagnosis and even filing a claim with GM. The vehicle is still experiencing these problems with the hard shifting. I had the recommended maintenance performed on the vehicle which included fluid replacement without a resolution to the issue. I have completely lost confidence in the GM products and their service technicians as they've been unable to repair the vehicle to proper running order. This will be my last GM product, and that says a lot coming from a GM family member. Sad that quality has significantly gone downhill.
