Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle briefly hesitated and experienced hard shifting before returning to normal functionality.

The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 60,000.
Truck has been burning oil since it was purchased new in 2020. The truck has needed 6 quarts added between every oil change. It has been to the dealer and they insist nothing is wrong. GM customer service has been no help. Motor has a ticking noise. Finally 2 weeks ago check engine lights came on and loud noises came from motor. Brought it into the dealership and they said full lifter failure and engine scoring and has been like this for awhile now. This is something I brought up to them AND GM support over the last 4 years of owning the vehicle and they always told me there was nothing wrong with it. Private extended warranty is going to cover a new engine, but is on national backorder due to all the issues with the 6.2L engine and others having issues GM won-??t acknowledge.
Purchased not thinking there would be issues as truck was clean and well kept. Month and a half later torque converter went bad. Had it replaced under warranty, however, I have more symptoms from when it originally started. 6 speed transmission.

Purchased a 2020 Silverado 1500, 5.3L 4x4 with 8,000 miles. Now at 66,000 miles the torque converter is bad. Shudders, hard shifting, lunges into gear, won-??t go into reverse at times. MULTIPLE complaints with these engines. There-??s a recall, but it stops at 2019-??.. WAKE UP GM!! This problem is still ongoing from 2020-2024!!! Needs to be another recall
First incident was when the vehicle had under 7,000 miles. Transmission module went. Vehicle wouldn't move. A few months prior, when we pulled our camping trailer, the integrated brake didn't work and the truck brakes overheated. Took vehicle to dealer, couldn't find a problem. A few months later the truck would not move, and found to be the transmission module. After a month and they finally got the part and repaired, no problems with pulling the camper. Than last week, we pulled out on the road, and we couldn't accelerate. A little over 45,000 miles on it. Had towed to dealer, they have diagnosed Transmission Valve Body. No warning lights. Maybe the transmission was hesitating some before it went. Waiting for the part, which no clue how long it will take.
2020 Chevy Silverado 1500 8L90 transmission failure at 40,000 miles and I am now at 90,000 miles with the same issue. I have been working on this truck tirelessly tried to fix the transmission. I-??ve had 3 transmission fluid replacements and a full torque converter replacement. General Motors knowingly sold these models to consumers when the transmission was faulty and underperforming. It shudders, shakes, and slips while driving. It-??s almost caused me to get into a few accidents. I just want compensation and to be a part of the class action lawsuit they are being filed upon.

about a month ago, began with a shutter or studder at low speeds. Became worse and a vibration on the interstate as it sounded like i was driving over rough ground. have now seen two mechanics in person and talked to another on the phone and all are saying the torque converter needs to be replaced. the check engine light has not come on which is also a concern as this is a major issue. safety concern is getting on the interstate into traffic and difficulty accelerating. experienced a lockup and swerve when accelerating up a hill which is very scary as my children were in the car. this is a 2020 silverado 1500 purchased new from dealership with 105k miles
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.
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.
My 2020 Chevy truck falls under the recall out right now. I drive my family around in it and feel a bit unsafe. How long does General motors have a remedy for this recall" And what are the next steps if a remedy isn-??t made in the timeframe allowed" I-??ve contacted General Motors and cannot get an answer. Thanks

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.
