The contact's fiancé owns a 2019 Chevrolet Silverado 1500. While driving 65 MPH, the vehicle independently stopped with several unknown warning lights illuminated. The transmission resumed normal operation soon after the failure before failing again. The contact later discovered that an Over-The-Air (OTA) software update was performed on the vehicle without the owner-??s knowledge. The vehicle was taken to a dealer where another software update for the brake control module was performed. The failure occurred for a second time as the contact's fiancé was driving again at 65 MPH; however, he managed to drive the vehicle home despite the repeated failure. The manufacturer was notified of the failure and her fiancé was offered a gift certificate for his next oil change. The vehicle was not repaired. The failure mileage was approximately 52,000.

Hello, I am having issues with my 2019 Chevy Silverado's transmission. When I go to drive it, sometimes coming out of first gear I will have hard shifting. The shifting is to intense that I have to let off of the gas, so my truck and idol down. This is a big issue when I am in heavy traffic, with a rick of being hit by other cars traveling faster. I have told my dealership about this multiple times and the last time I talked with them about this. I had them flush my transmission, thinking that would help. After that was done, the service manger told me. The way my transmission is shift is standard GM operation. Sometimes I will have a warning lamp come up. The fault code is "lost communication with transmission".

On the dash display when shutting the vehicle down states "shift to park" and will not power down unless you constatntly move the vehicle backwards and forward multiple times before it powers down. This was replicated at the dealer and the shift assy was replaced under warranty in 1/21 but now 3/22 it is doing the same thing again. Dealer contacted says out of warranty contacted GM customer service case # 9-7518724528 and waiting on GM's position at this point this is a problem with many GM products per the internet and if it is not shifting to park becomes a safety issue GM has service bulletins listed on alldata but no recalls at this time

Dashboard and display screen doesn't shut off when key had been removed from the ignition. Constant freezing, call dropping and sound boost at random moments. Ticking sound when barely touching the gas. Hard shifts. Bluetooth connects and disconnects constantly. If GM released a defective vehicle, in which they are aware of the problems should be fixed. Not only for me but for the tons of thousands filing known major problems as well.

I bought the truck in Oct. of 2019 with 5000 miles on it. I have taken it to several service shops since then. I have told every one of those shops fro 2019 to present that there was something wrong with the truck. There has always been a hard clanking noise in the rear end. It always feels like it's in 4 wheel drive. It has never shifted right. When pulling a load it fells like it jumps in and out of gear. And when shifting from reverse to drive it clanks in the rear end. It feels like there is a brake dragging because when I let off the grass it will practically stop itself and it sound like a wheel cylinder is going out. Sometimes I have to push the start/stop engine button 2 to 3 times before the truck will shut off. The screen of the radio goes black sometimes. The rear tires don't turn when in 4 low. The tail gate doesn't lift like it's supposed to. The heater isn't right when you turn the defrost on it blows out at you feet. And when it remote started the heater doesn't always come on. All the reportes can be seen through the Chevrolet dealerships or OnStar. It has been taken to several different dealerships since 2019 when I bought it.

Driving on state highway and truck felt like it went into neutral. Pulled to side of road and put truck in park. Put truck in gear and nothing happened. Truck would not move from side of the road. Had truck towed to dealership and was told that the transmission was burnt out and had to be replaced. 2019 Chevy Trail Boss with 90k miles and the transmission fails. Unbelievable.

1st Time I was idling for 30+ minutes, truck was also making strange knocking noises, pulled on to a major highway and rear end locked up, cars were slamming on brakes, almost got killed. Took to shop left for 2 weeks, they said they could find no issues. I assumed they fixed problem, because there was no knocking any more. 3 weeks later, was idling for about 45minutes, pulled into traffic, dark, raining, rear en locked up. Almost got killed a second time. Took in for service and left truck. This needs to be investigated before someone gets killed!

Truck has excessive shuddering accelerating or decelerating. According to the service person at the dealer it is a problem with moisture and the factory fluid that the truck came with. Diagnostics showed excessive TCC Slippage which requires and upgraded transmission fluid. The TCM was also reprogrammed with the latest calibrations. Total cost $654.30.

6L80E 6 speed transmission. Vehicle slips at low speeds, under light acceleration. Sometimes when it shifts, its very hard and jerky. If this is normal designed operation, the transmission or programming needs to be redesigned.

Event in Order: -AutoStart, failure -Started with key --??Action Required-?? - -??Steering Assist Is Reduced, Drive with Care-?? --??Service-?? - -??Trailer Brake System-?? --??dash panel information-?? not available -?" Fuel Economy and oil life --??Traction Control light on-?? -Put truck in reverse, gear not engaged, no response -Put truck in drive, worked, but steering very difficult and made vehicle not safe to drive and/or operate. This has happened to me once before but not to this extent, last was when I was driving and thankfully I was able to pull over and turn the vehicle off. It would not start after repeated attempts but finally started after and functioned normally. These events had not check engine lights and when serviced, the mechanics said they didn-??t see anything when scanned. OnStar diagnostics had no report when I had it active. I bought this truck less than 18,000 miles ago. Initially bought at 17,181 miles on Feb 22, 2021 and is now at 34,675 miles as of Oct 29, 2021. This is a safety concern as the steering fail can potentially lead to an accident if the truck can-??t be controlled. Traction control failure can lead to the vehicle becoming stalled in a dangerous situation. Brake systems can lead to unwanted breaking and/or being unable to break. This truck is a danger to operate. I do have video but, upload does not support MP4 format.

Same issue I had with my 2017 Colorado. Shutter/shake when accelerating between 1 & 2. Issue started around 64k miles. Thought maybe it needed the same transmission flush to the newer fluid. Dealer called after 4 days of holding my vehicle (with no loaner or rental option) to tell me that the trans needed an "update" and that it would cost me over $500 since I was over warranty at 67k. There's already a bulletin for the Camshaft Position Actuator Magnet Replacement, which supposedly memics the same issue. However the dealership says "that's not the problem". I'm sure the same trans issue with hard gear shifts is probably related to this issue now. I haven't felt the hard gear shift in a while but it would do it randomly when accelarating out of my driveway.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 10 MPH, the rear wheels inadvertently locked. There were no warning lights illuminated. The contact stated he veered to the side of the road, shifted into park, and turned off the vehicle. The contact was able to restart the vehicle but waited about four hours for the wheels to unlock. The vehicle was taken to the dealer who informed the contact that they were unable to diagnose the vehicle. The contact stated the failure had been reoccurring while driving. The contact became aware of an unknown customer satisfaction program for the failure. The vehicle was taken back to the dealer who informed the contact that he would be responsible for the cost of the repair because the vehicle was out of warranty. The manufacturer was made aware of the failure and referred the contact to the dealer for assistance. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 12,000.

Truck lunges forward sometimes. It will work properly most of the time and then after stoping, when you tramp on the gas it will hesitate then lunge forward. As I said most of the time it works properly. I consider this a very real hazzard, has been doing this for months. One day at my golf club while pulling into my parking spot, a tight fit, I had to back up to get into my spot. When I tried to go forward it had about a two second hesitation then squealed the tires. I have witnesses. My dealer says everything with the truck is normal after they inspected it. The internet is full of the same thing from other owners of the same truck.

On September 11 at approx. 1630 hrs. my wife and I were going out for dinner. I stopped at a stop light on a hill. Transmission in Drive, foot on the brake. Our truck suddenly started rolling backward. I looked at the dash, no warning lights, gauges still working, transmission in drive, I stood on the brake pedal, no effect, I put the transmission in park, no effect, I engaged the parking brake, no effect other than the parking brake warning light came on. We had rolled back approximately 50 feet. I looked in my rearview mirror and observed a car approaching. Luckily he/she saw my problem and stopped. Things suddenly started coming back to life and came to a gentle stop. When I looked in my mirror I was so close to the car behind me all I could see was his windshield, no hood. I moved the transmission from park to drive and we continued on. I have contacted the dealer and they are attempting to determine what happened. However, I am afraid this will happen to someone else who may not be as lucky as I was or that it may happen to me again. I pull a 5th wheel trailer with this truck.

My truck has a vibration when going down the highway at speeds of 70 mph. The dealer has done a transmission flush but still have the same issue. I am afraid that the driveshaft or the transmission may lock up while we are on the highway with the family.
