2020 Chevrolet Silverado 1500 Power Train

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds or at a complete stop, the vehicle jerked while depressing the accelerator pedal with the check engine warning light illuminated. The vehicle was taken to several dealers where the spark plugs, engine wiring, and other various parts were replaced; however, the failure persisted. Upon investigation, the contact discovered NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 87,500.

The truck is only three years old with 123,000 miles and the transmission needs to be replaced. I took the truck to Chevy and they said the transmission is bad and they need to replace it. GM and Chevy will NOT cover the cost to replace the transmission or help with any cost. This truck is fairly new and it's a lot that the transmission is already bad. Chevy quoted me $7,990 for new transmission with install.

Transmission continues to lock up while driving

Rear end went out within drivetrain warranty period. Chevy claimed it was due to a leak even though there was no evidence of one and they couldn’t produce the part. Almost immediately after getting it back it started to have transmission problems (8L90). They again claimed there wasn’t a problem. The truck now has 120,000 miles on it and we are replacing the transmission after it would drop gears and, finally, wouldn’t go into reverse.

The specific issue that is being recalled is malfunctioning on my vehicle. I have taken to the dealership but they won’t help because the solution hasn’t been identified. My truck has suffered repeated failures resulting in excessive wear and tear on the transmission. I’m afraid a catastrophic failure will occur if I have to keep driving, without a solution. The dealer simply cleared the code. They should replace the part that is failing at a minimum. Even if it might happen again down the road. They will have a solution by then.

2020 Chevrolet Silverado 1500 Custom, bought new on August 10, 2020. On August 24, 2020 I returned the vehicle to the dealership with 524 miles on the odometer, for hard downshifting at low speeds. The technician returned the truck with 531 miles, stating that he could not duplicate the issue. The issue continued along with occasional shudder at speeds around 40-50 m.p.h. On December 14, 2022 I took the truck to a different dealership with 1,616 miles and it was returned with 1,625 miles on the odometer. The technician found a slight shudder at 25-30 m.p.h. under light acceleration, but could not duplicate any other malfunction. The technician stated there was no metal debris in the fluid pan and performed a flush and refill of transmission fluid, installed updated thermal bypass valve and three seals. The issues still persisted, but not as harsh or as frequently prior to this service. I returned to the original dealership again on September 3, 2020 with the same concerns at approximately 28-K miles. Again, after having my truck (4) days, the original dealership's technician stated that he could not duplicate the problem(s).

This vehicle, only 4 years old, experienced lifter/engine failure during normal operation, which required unsafe driving conditions and a roadside emergency. The vehicle was towed to the service location, where a complete engine disassembly took place, and required a 3 week repair period. The truck experienced a rough idle/shudder at a stoplight, then proceeded to show a flashing check engine light (P0305), a service emergency brake warning, and a service traction control warning.

Truck was purchased from an authorized chevy dealership less than 6 months ago. Truck had transmission service just before purchasing it as it was *maintenance* not repairs. However all of a sudden the truck will stop accelerating in the middle of intersections where you typically would have a 1-2 or 2-3 shift. along with during acceleration on highway it will decide it doesnt want to shift anymore to a higher gear than 4th or 5th. This is causing a constant safety threat as i cannot control when the vehicle will move under its own power. This is a known problem with cheverolet as they will replace the parts that cause this if its under warranty however mine is not. Although the warranty is up the issue is caused by poor manufacturing process and they know that.

torque converter and transmission. For more than a year truck would lunge or jump forward when stopped at light or sitting in traffic, brought truck back to dealer several times for this problem each time they would tell me nothing wrong with truck. problems continued to happen and Truck started hesitating when accelerating then jumping into gear also while driving on highway truck felt like it was slipping out of gear and RPMs would jump up. Brought truck back to dealer again 3 months ago and they said torque converter was going bad and they would call me when part was in. two months later and they kept saying it was back ordered, now while driving going down steep incline into busy intersection felt like i got rear ended by another car, when looking back no car was close me truck stalled and started rolling into intersection I slammed on brake and got truck started again only to find transmission had failed and it slammed into gear when accelerating put my flashers on and got off road . Brought truck back to dealer to have them tell me transmission was now gone. truck has now been sitting on dealer lot for a month now with them telling me they can't get parts or transmission to fix. Very dangerous situation with this transmission and them knowingly kept sending me away in this truck. I feel that they knew about transmission problem over a year ago when I was bringing it in for the lunging forward after coming to complete stop at traffic light and kept saying nothing wrong. Truck was still under original warranty and only has 62k miles on truck.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 30 MPH, the vehicle briefly vibrated and shuddered before losing motive power. After tapping the brake pedal and rapidly accelerating, the vehicle continued to vibrate and shudder but eventually returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 78,000.

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.

Everytime I trun 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.

the transmission on my truck shudders and shakes very badly, contacted GM ,also the dealer told it would take 3-4 weeks to repair , i am left without away to work.

My transmission went out

Power Train Transmission Torque Converter “Chevy Shake” Multiple symptoms. - Shuttering , “ buffeting” , slipping sensation. Continuous almost like “strong wind gust” or “head wind” - Humming, if you have ever heard a “high pressure” hydraulic equipment. - RPM bounces 300 to 500, but transmission does not “down shift” (while driving) - Vibration, of the truck can be noticed, felt at various speeds, 40mph to 60mph(shutter) almost like it struggling to get up to speed (unless heavy on the gas pedal) 70mph and above to say 80mph, then shaking, vibrations worse when coasting back to 70 mph Vibration will “not stop” until truck speed is drastically slowed or come to a stop. - Steering wheel “shakes” , “vibrates” also can happen at 60mph to 70mph and above to say 80mph, then worse when coasting back to 70 mph - “Clunk” when stopped and shifting into “reverse” (new development symptom) Vehicle is in for inspection .

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.

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.

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

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

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.

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.

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

Transmission keeps over heating to the point that a message comes on display “Transmission hot idle engine” have had this same problem before to it to the dealership they installed a temperature bypass on and this problem continues
