2020 CHEVROLET SILVERADO 1500 Complaints

On the transmission for the 8-speed I'm wondering why mine hasn't been recalled when all the others have been recalled were made the same basically time. And I'm having the same issues as those other transmissions

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle was running rough and the vehicle lost automotive power. The check engine warning light was illuminated. Additionally, the transmission made an abnormal sound while starting the vehicle and while driving, and the torque converter was shuddering. The contact and his father diagnosed the vehicle as having a cylinder misfire and performed a compression test on the engine. The contact replaced the lifter and push rods, deactivated and removed the Dynamic Fuel Management (DFM), modified the engine, replaced transmission fluid, and used Lube Gard Instant Shudder Fixx for the torque converter shudder. The manufacturer was made aware of the failure. The failure mileage was approximately 76,000.

Unknown which system failed. While driving on the freeway, truck lost power for a few seconds. Dash lights turned off and back on. Our safety and the safety of others on the freeway were at risk as we had no control of the vehicle. Have not had the truck checked for the problem. Scared to drive it. No warnings appeared.

Odometer Fraud. The contact owns a 2020 Chevrolet Silverado 1500. It was discovered that there was a mileage discrepancy. The contact stated that at the time of purchase, the vehicle mileage was approximately 54,753. The current mileage was approximately 56,000. As per a Carfax report, the contact discovered the vehicle was reported stolen on May 2nd, 2025, with the vehicle mileage at 102,610. The contact was concerned that the odometer was altered prior to the purchase.

Description of Problem: While driving, the engine intermittently revs on its own without any input from the accelerator pedal. During these episodes, the vehicle also shakes/vibrates noticeably. This has occurred [once / multiple times — specify frequency, e.g., “several times over the past X weeks”]. The engine revving is not consistent with normal acceleration and appears unrelated to throttle position. The shaking is felt throughout the cabin and is most noticeable [at idle / at speed / when the revving occurs — specify if known]. Safety Concern: This creates a risk of sudden, unintended changes in vehicle speed or loss of control, particularly if it occurs in traffic, while merging, or at highway speed.

The Electronic Parking Brake System on my 2020 Chevy Silverado 1500 continuously malfunctions. Chevy/ GM Customer Support has been made aware of this issue and continues to disregard it entirely. The Electronic Parking Brake, which is an automatic function that cannot be turned off or bypassed, fails to fully disengage when the vehicle is taken out of Park. The Electronic Parking Brake remains very slightly engaged, producing a slight noise while driving and causing excessively premature wear on the vehicles pads and rotors. My vehicle has about 64,000 miles on it, and I have had to replace my rear brakes twice now already, due to this issue. The majority of those 64,000 miles are from uninterrupted highway driving. Each time the rear brakes were replaced, I had the dealership inspect the braking system. The dealership was not able to definitively confirm for some reason but was able to speculate that the aforementioned is likely what is going on. I find that any malfunction of such a critical part of the vehicle and the safety of it's operators and passengers poses a major safety risk.

Key will not fully turn back and release, keeping the accessories running. After many start, shift, move a little and waiting for a period of time it eventually turns to normal to remove. I’ve seen articles on if it says “shift to park” on the dash lights and it does not. Bought used with 70,000 10/24 and continues to get worse.

While driving my transmission has a shutter. The shutter started about yr and half ago and I have just maintained with shutter stop. I know there is a recall on manufactured parts for other Chevrolet trucks in the same yr

While driving my 2020 Chevrolet Silverado 1500 equipped with the 5.3L V8 engine and Dynamic Fuel Management (DFM), the engine developed an internal valvetrain failure resulting in misfires, rough running, and reduced engine performance. The vehicle was diagnosed by a Chevrolet dealership as having failed lifters associated with the DFM system, requiring major engine repairs and replacement of internal engine components. The failure occurred at approximately 81,000 miles and resulted in the vehicle entering a reduced performance condition, creating a potential safety concern when merging, accelerating, or operating in traffic due to the inability to maintain normal vehicle speed and power. The vehicle was inspected and repaired by an authorized Chevrolet dealer. Research shows numerous similar reports from owners of GM 5.3L and 6.2L engines equipped with Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems involving lifter and valvetrain failures.

Dear Sir or Madam, I am submitting this complaint to request that the Federal Trade Commission investigate General Motors (Chevrolet) regarding what appears to be a known engine defect affecting the 2020 Chevrolet Silverado and the company's handling of this issue. I own a 2020 Chevrolet Silverado. In September 2025, when my truck had only 45,494 miles, I experienced an engine misfire consistent with a defect that has been widely reported by other owners. Through my research, I discovered that General Motors was aware of this issue and, rather than correcting the underlying mechanical defect, reportedly issued a Technical Service Bulletin (TSB) instructing dealerships to reprogram the Engine Control Module (ECM) to reduce or mask the symptoms instead of permanently repairing the root cause. Now, less than one year later, my truck is experiencing the same engine problems again. Although my vehicle has relatively low mileage, it is no longer covered under the factory warranty because of its age rather than its mileage. When I contacted Chevrolet Customer Assistance, I was advised to work with my local dealership to determine whether I might qualify for a "goodwill" repair. I do not believe it is fair for consumers to rely on discretionary goodwill assistance when the manufacturer was allegedly aware of a design defect before or during the time these vehicles were sold. Based on my research, properly repairing the underlying cause of this engine failure can cost as much as $15,000. Consumers should not be expected to bear the financial burden of repairing a defect that the manufacturer allegedly knew existed but failed to adequately correct. I respectfully request that the FTC investigate whether General Motors engaged in unfair or deceptive business practices by: Continuing to market and sell vehicles with a known engine defect. Addressing customer complaints with software reprogramming rather than permanently correcting the underlying mechanical issue. Failing
