My car turned left with the risk of jumping to the opposite lane. It happened twice. First at 40 mph and the second time at 70 mph. I didn-??t feel any issue with the steering drive but more with the traction. I-??m not sure.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was shuddering while depressing the accelerator pedal. The contact also stated that after cold starting the vehicle, the vehicle shifted hard from first to second gear. There was no warning light illuminated. The vehicle was taken to a dealer where the transmission fluid was flushed; however, the failure persisted and became more frequent. The manufacturer was notified of the failure and agreed to cover half the cost of a new transmission. The vehicle was not repaired. The failure mileage was approximately 59,000. The VIN was not available.

at around 30mph the transmission struggles and jerks.

- Bozeman, MT, USA

Everytime I turn the car off, all the lights, Nav, radio stays on as the car display a message "Shift to Park". This message stays on for sometimes 2 minutes, sometimes 10 minutes. Untill the message gone the car still thinks is on. In 2 occasions I had to jump the car as the battery depelted. This is a major safety issue if my son who drive the car to Detroit and had to stay wait for the car to turn off. GM need to fix this issue ASAP. I called the dealership & they said there is no recall or any fix. I see many many ppl complaining about the same thing with different Chevy models.

I purchased this truck new and it's now been back 8 times for a engine hesitation, misfire, and check-engine light. On this 8th visit, they replaced the "right bank" of lifters on this 5.3L V8. Previous visits have replaced fuel injectors, spark plugs, spark plug wires, and flashed the ECM. I'm not sure why GM didn't replace the left bank of lifters if it's a known bad part (or replaced the engine entirely). Now I'm just waiting for the problem to come back for a 9th time for yet another part to replaced on an obviously poor engine design.

- Gilbert, AZ, USA

Component? Multiple: lifters from bank 2 which caused multiple other components to be replaced consistent with GM protocols such as bent rods. Safety: The vehicle jerked causing it difficulty to safely operate the vehicle which ultimately left stranded. This was also unsafe for other motorist as it was difficult to operate while trying to safely get to the side of the road. The dealer repaired the vehicle after confirming failures. No one other than the dealer inspected the vehicle to date. Warning lamps only appeared after vehicle violently shook.

My transmission went out

- Fullerton, CA, USA

Vehicle is at 67, xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake..... the gas pedal has locked on me already with my 3 small children in the truck at highway speeds. GM says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week Vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.

Transmission will hard shift from 2-3. It jerks the truck and causes power loss when in traffic. The RPM's will go up to 3500-4000 and then the truck barley keeps a speed of 45 mph. The engines sounds like it is going to explode! This has happen several times with 32000 miles on the truck.

- Gulf Breeze, FL, USA

Truck was purchased new in 2020. The transmission has worked fine until recently. Since this summer there is a distinctive whine coming from the engine department. Very hard to isolate. The transmission this winter has been terrible. The cold functionality of the transmission now is even worse than when new. It hesitates to shift to second and to third gear when cold. The transmission now also exhibits a failure to up shift when the vehicle is moving. It will hang with elevated rpms 2300 to 3000 for a second or two before upshifting and lowering the rpms. The truck now also has random clunking when shifting into reverse from dead stop. The transmission does not shutter but there is definite loss of power and that can be contributed to a bad torque convertor. If it is not locking up correctly when in gear power will suffer to the convertor failing to engage the transmission correctly. The shifting issue have persisted and gotten worse. Dealer said he put a computer on it and said there were no codes. The dealer mechanic did not even try to road test the truck That is just ridiculous. I will be taking the truck in again

- Brockport, NY, USA

I drove approximately 8 miles to lunch and parked the truck. It sat about an hour and when I started the truck to leave I had a message to service esc and power steering reduced. The tuck had no power steering. Returns to work and the truck sat about ten minutes. Then everything started normal and is fine.

Shaking an jerking in transmission in all gears.could be a serious issue if it locks up or stops pulling at speed or in heavy traffic

- Georgetown, TN, USA

The 2020 Chevrolet Silverado has a known issue with the torque converters and they are currently on back order and our service manager told us we are able to drive with it messed up and that it would not cause anymore damage but it causes transmission lockup and engine lockup which results in loss of control.

- Orlando, FL, USA

Vehicle exhibited sudden loss of power at highway speed while in West Texas. Without warning, the vehicle displayed an "engine power reduced" message and the vehicle immediately slowed from highway speed to a maximum speed of 25mph. This sudden reduction in power required the drive to take emergency action to leave lanes of travel for the shoulder. On a road with insufficient shoulder-area, this could have resulted in a collision. Prior to the loss of power, a check engine light illuminated followed by a "Service Emissions System Soon" warning on the driver information display. The elapsed time between the messages and the loss of power was less than 5 minutes. The vehicle did not exhibit any erratic behavior at the time of the warning lights or prior to the loss of power. The vehicle is currently at Bill Estes Ford in Indianapolis, IN. Diagnosis is underway. Indications are that this is related to issues with the emissions control system. The vehicle was up to date on all service at the time of the incident.

Sunset jerking of vehicle, hesitation of vehicle when accelerator is hit at random times, when taking off from a traffic light or while cruising. If simmering need to get out of the way this could lead to vehicle hesitation and safety issues that could cause a crash. No errors were given in computer when dealership looked at it.

- Lithia, FL, USA

Torque converter faulty and told vehicle unsafe to drive. Only about 12,000 miles on vehicle. It was skipping gears while driving. It appeared initially very small and almost unnoticeable, but got worse over time going back a few weeks at least. The dealer has had the vehicle for over 30 days and cannot get the part shipped to them. They told me it MAY be shipped on October 22, while I dropped the car the first week of September.. Being told it is unsafe to drive, it definitely put us in danger driving it. Service Bulletin so they know about the problem: https://static.nhtsa.gov/odi/tsbs/2020/MC-10184489-9999.pdf

Truck mileage approx 26000 miles. 2 wiring harness locations rubbed wires enough to cause wire to wire contact resulting in 1 location, burnt wires, according to service tech and the other resulted in truck malfunction. Threw numerous codes, transmission repeatedly went P, D, P, D....unable to put in park for sometime and then finally was able to. Additionally, when serviced out of state, was recommended to have service done for leaky oil pan. Upon returning to home state, truck went in for oil leak, was returned due to parts ordered because it's leaking at the rear main seal and not the oil pan. Waiting on this service to occur.
