| Jul 2026 | POWER TRAIN | 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 | Crash: No Fire: No | Unknown |
| Jul 2026 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Jul 2026 | ENGINE | 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 | Crash: No Fire: No | Unknown |
| Jul 2026 | POWER TRAIN | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at approximately 40 MPH, the vehicle shuddered and downshifted independently. No warning lights illuminated. Additionally, an OBD2 diagnostic scan retrieved diagnostic trouble codes: U0146, U0101, and U0100. A local dealer was contacted; however, the vehicle was not diagnosed or repaired because the VIN was not included in any recall. Additionally, the contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train). The manufacturer was not made aware of the failure. The failure mileage was approximately 84,000. | Crash: No Fire: No | Unknown |
| Jul 2026 | ENGINE AND ENGINE COOLING,FUEL SYSTEM, GASOLINE,ELECTRONIC STABILITY CONTROL (ESC) | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at 35 MPH, the engine started knocking, and the sound grew louder while making a turn. The Electronic Stability Control and check engine warning lights illuminated. The vehicle was taken to a local dealer, where one diagnostic trouble code was displayed, but the vehicle was not repaired. The vehicle was then taken to a second local dealer, who retrieved a code for fuel injector number eight and diagnosed that the engine needed to be replaced; however, the vehicle was not repaired. The vehicle was taken to a third dealership, Knapp Chevrolet, where it was diagnosed that the engine needed to be replaced. The vehicle remained unrepaired. The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 94,000. | Crash: No Fire: No | 94,000 |

| Jun 2026 | ENGINE | I am filing this complaint regarding a major engine failure in my 2020 Chevrolet Silverado 1500 equipped with the 5.3L V8 engine. At approximately 56,000 miles, my vehicle experienced a failed valve lifter, resulting in loud engine ticking, a check engine light, loss of power, and unsafe driving conditions. The vehicle was no longer operating properly and required immediate repair. Although the vehicle had been regularly maintained and had relatively low mileage for such a significant engine issue, I was informed that the failed lifter damaged the camshaft and related engine components, requiring extensive repairs. The total cost of the repair was $6,180, which I paid out of pocket. My Silverado was just outside Chevrolet's 5-year/60,000-mile powertrain warranty period by time, despite having only 56,000 miles. A major internal engine failure should not occur on a well-maintained vehicle with such low mileage. After researching this issue, I discovered that lifter failures involving the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems in GM's 5.3L engines have been widely reported by other Chevrolet Silverado owners. This indicates a potential design or manufacturing defect rather than normal wear and tear. I am requesting that General Motors provide reimbursement or goodwill assistance for all or a substantial portion of the $6,180 repair cost. I believe customers should not be responsible for paying thousands of dollars to repair a known issue on a low-mileage vehicle. I respectfully request that this matter be reviewed and resolved promptly. | Crash: No Fire: No | Unknown |

| Jun 2026 | POWER TRAIN,ENGINE | I'm experiencing all the documented issues with the 10L80 10 speed transmission. Identical to all the recalls. It's shifting poorly, torque converter shudder, lose of power, unreliability, and serious safety concerns. I've tried to communicate and find a resolution to these issues through the dealership and GM. Of course getting nowhere. I don't feel a 60k dollar truck should be in this kind of condition. Recently the ac compressor went out. Conveniently after the 6.2 was considered faulty and was replaced but transmission denied. Which the dealership GM expressed in no way was any factors the warranty companies claims of a taller tire being on the truck. Being the issue at all for the transmission failure. Also the dealership didn't check a box. One that I can not physically check. Which they put on me. They swapped the stock tires to the taller brand new set I'd just bought for my trade in. Never stating anything about the tires being taller voiding the warranty I just paid for. Why would I deny the part of the extended warranty that I wanted. Cause of the suspension and drivetrain. Either way this truck is not safe to be on the road. It struggles to maintain speed on the highway. Eventually leading to the torque converter free spinning and making all kinds of noises and vibration. Of course once I've assisted it to violently shift through the gears and hopefully into 10th. On occasions it never makes it that far. Either way I feel this falls directly into the recalls with the same model and year. They replaced the 6.2 cause of cylinder failure and oil consumption. Well the next in line for the drive train is the junk 10 speed. Not sure how it can't be related. The long and stressful time. I've put into finding a solution with the dealer or manufacturer. They blow me off or just don't give me any info. I feel that's their way of dismissing not only the failure of the salesman not properly doing his job. Which the GManager also stated mistakes happen.

| Jun 2026 | POWER TRAIN | GM has a known recall and special coverage N242454441 to cover the exact same issue I experienced on my way home from work. However, I am informed my model is not included in this special coverage. The issue I experienced while attempting to turn into my apartment complex on a busy road [XXX] my rear wheels locked up mid turn no warning signs, no lamps, no messages or other symptoms were present. Almost causing me to get into an accident had traffic not stopped. I was able to shift it into park and then to drive to immediately pull off to the side into a parking lot and put my OBD reader I have P0747 solenoid 1 failed locked on. I was informed by GM that they could attempt to reprogram the transmission control model, however based on research this is not the root cause of the issue it is due to the soft aluminum bores causing the transmission module to ware and fail.

| Jun 2026 | POWER TRAIN | Our truck started hard shifting and lurching almost a year ago, the check engine light will come on, sometimes the truck will go into safety mode, then the check engine will be off. The problem progressed and we had it diagnosed as a bad transmission control valve which we were made aware is not available to get replaced because of the ongoing recall on other vehicles in the same year range as ours, just not ours specifically. We need to get this fixed and if others are getting it fixed on recall ours should be as well. Otherwise we have a barely usable vehicle, that my husband relies on to get to work, sometimes hours from home, with no way to fix it, a year left of payments, and diminished value because of the transmission issue...that again others are getting fixed at no cost to them. Even without the recall we can't get it fixed because all available parts are going towards the recall. We deserve to have our vehicle added to this recall so we can get in line to fix it. We have been loyal customers for over 20 years to our local dealership Rydell Cheverolet. The incident date is ongoing for over a year but I will put in the most recent date where my husband was almost stranded 300 miles from home. | Crash: No Fire: No | Unknown |
