| Dec 2025 | POWER TRAIN | My 2020 Chevy Silverado needs a torque converter replacement. My truck is at 90k miles and out of drivetrain warranty. However, this is a known GM problem with trucks (and other vehicles in this class of engine/transmissions). I have talked to GM corporate and they are only willing to rebate 20% of the cost of this repair. I believe they should pay for the entire repair since this is a known problem for all these vehicles in this class. Please help me to get GM to understand this and fix this known problem. | Crash: No Fire: No | Unknown |
| Dec 2025 | STEERING | Sudden intermittent loss of power steering, issue confirmed by Chevy Dealership. No warning lights were displayed. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | Transmission, would lock up for no apparent reason . At random speeds, they continue as if nothing was wrong. Took to dealership, couldn't get to it for a week. End up at a transmission shop said it through some code. required rebuilding the transmission . 88,000 miles on truck. From time of first incident to first shop visit one week. Same transmission in similar trucks is under recall but this vin# is not. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | THIS IS A RECALL REMEDY FAILURE REPORT UNDER 49 U.S.C. §30120. My 2020 Chevrolet Silverado 1500 (VIN: [XXX] ) received Recall 24V797000 on June 9, 2025. The ECM update is intended to detect incipient clutch-pressure or gear-ratio deviations—early signs of a developing slip—and automatically force limp mode to prevent rear-wheel lockup. On August 23, 2025, after the recall was performed, the truck experienced rear-wheel lockup at highway speed. Limp mode did not activate, which shows the recall remedy failed to operate as required. Mangino Chevrolet documented symptoms matching the recall defect, including abnormal ratio behavior. No metal debris was found in the pan, indicating the failure was not caused by wear. GM TAC also noted behavior consistent with a developing slip. GM first recommended full transmission replacement at my expense before acknowledging the recall. GM later authorized a valve-body replacement, which also failed. The dealership owner provided a written statement confirming that: (1) the recall remedy did not correct the defect, and (2) the valve-body repair did not correct it. On December 3, 2025, GM Customer Assistance attempted to close my case as “not recall-related,” despite the post-remedy lockup, limp-mode failure, dealer findings, and the written admission that the recall remedy was ineffective. The safety defect persists after recall completion, and GM has not provided a remedy that corrects it, as required under federal law. I am reporting this as a failed recall remedy and an ongoing safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | During driving at low speed 15-30mph with 4 wheel drive set to auto. 4 wheel drive engaged and rear wheels locked up. Turned off 4wd no issue. Upon arrival at the dealer a bad sensor was determined to have caused the rear wheels to not perform as designed. After resolving the issue now I hear rubbing metal noise from the drive shaft. Spoke to Chevy about the issue haven’t heard back. | Crash: No Fire: No | Unknown |
| Nov 2025 | VEHICLE SPEED CONTROL,SERVICE BRAKES | My truck started acting sluggish like the parking brake was applied while driving. At a traffic light I put the vehicle in park applied and released the parking brake. I put the vehicle back in gear an let off the brake. The vehicle did not move so slightly pressed the accelerator. The vehicle still acted as if the brakes were applied. I could feel the slight movement and torque being applied but only slightly lurching. The traffic light turned green so I proceeded up to 45mph. A vehicle in front of me slowed to make a turn. Applied the brakes and nothing happened. I pressed the brake so hard that I lifted myself off the seat. I swerved to miss the vehicle avoiding a collision. Then warnings started popping up; "brake system failure max speed 62mph", "brake system failure max speed 42mph", Brake system failure", service traction control", "service trailer baking system". among others I was too busy to see all of them. I coasted to a stop in a nearby parking lot with visual and audible warnings still going. I shut the vehicle off then restarted it. Some warnings remained like traction control and the engine light. The vehicle appeared to be operating correctly so I drove it to a local dealer. they said there was a code for low voltage in the brake control module but couldn't get me an appointment for over two weeks. I took the vehicle to a regular mechanic who said what I described was impossible. That mechanic kept my truck for the balance of the day but could find nothing wrong. I no longer trust this vehicles brake system. In many scenarios the failure, were it to happen again could be catastrophic. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE | What component or system failed or malfunctioned, and is it available for inspection upon request? Based on information from ODI Resume EA25007 & Safety Recall N252494002, it is more than likely engine connecting rod bearing failure. How was your safety or the safety of others put at risk? I was traveling at freeway speed, 70mph when it occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? 11/25/25 at 12:33 (pacific), I am currently stranded 190 miles from home and waiting for the truck to be towed to the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has not. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Prior to Failure: Since I’ve owned the vehicle, I’ve notice slight ticking and slight knocking during cold start within the engine bay. At the time the noises seemed normal and not cause-for-concern. At Time of Failure: I was traveling on level grade on the highway when I heard a deep knock from the front, bottom left side of the engine bay. Within about a minute from the initial noise, I received a “check engine” warning light and a message of “ESC Warning” displayed on my instrument cluster. At that moment, I noticed the engine noise become more prevalent and constant. I immediately slowed and coasted to my next exit off the freeway. | Crash: No Fire: No | Unknown |

| Nov 2025 | POWER TRAIN | The transmission quite working while I was driving down the road. Took my foot off of the gas pedal and my truck bogged down completely and had no power to it. It is at an auto repair shop so I am unaware if it could be inspected under request. Took time but was able to safely get off the roadway and out of traffic. It did the out of no where. Started having some issues this summer but no warnings lights ever came on, so I didn’t think much about it. Completely stopped in the middle of the road and had little to no power from the transmission to the truck to move off of the road. My truck is currently in an auto repair shop waiting on a new transmission to be installed. I had it towed to an independent auto shop from where it stalled. There were not warning lamps or anything at the time of my transmission quitting. Truck started to run rough and shifting hard this summer but without warning lamps I didn’t take it anywhere. When running on the interstate it was shuttering which I thought was due to possible tire out of balance. It would also hesitate to take off when put into drive. It had several of the same issues that Chevy had on other transmissions that were recalled within this same time frame. | Crash: No Fire: No | Unknown |

| Nov 2025 | ENGINE | Driving at normal highway speeds, "service parking brake", "service engine", and "electronic stability control" lights illuminated on the dash with no prior warning. When attempting to accelerate, to maintain highway speed there was noticeable roughness to the engine along with a tapping sound. I slowed and made the trip back to my home under reduced power. The vehicle was towed to the dealer the following day per the dealer's service advisor instructions. Issue was diagnosed as a collapsed lifter, bent lifter rod and damaged cam lobe. Total repair cost exceeded $10,000. Internet search of this issue reports a number of drivers reporting similar issues with the Chevrolet 5.3 liter engine. If this issue had occurred in a more congested traffic area it could have caused an accident when my engine power was suddenly reduced without warning. | Crash: No Fire: No | Unknown |
| Oct 2025 | STEERING,SERVICE BRAKES,ENGINE | While driving on a residential side street my 2020 Chevrolet Silverado 1500 (81,996 miles) suddenly lost power steering and braking with no waring. Several messages appeared in the dash and the check engine light illuminated. I was able get the vehicle safely to the shoulder and put in park without power steering or brakes. At this point the engine stalled and would not restart. The vehicle was towed to the nearest Chevy dealer on 10/29/2025. The technician verified the loss of power steering, brakes, and several other codes and diagnosed the issue as corroded engine grounding straps per GM bulletin #23-NA-201. The grounding straps were replaced and the codes cleared. The technician test drove the vehicle and verified normal operation after the repair. I was responsible for paying the full cost of these repairs as my vehicle was out of warranty. I feel incredibly fortunate that this happened on a residential side street with no traffic. Had this failure happened on the expressway while pulling my 4,000 lb trailer, this could have been a fatal accident if I suddenly lost power steering, brakes and had the engine stall like it did. I see multiple complaints for this issue on the NHTSA website and the GM TSB for this issue dates back to 2023. I am shocked that this is not a nationwide recall yet. It is a significant safety threat to the driver and others. I also know this is not an isolated incident, as my service advisor at the dealer suggested it was probably the grounding straps before the technician even inspected my vehicle. It was pretty clear from our conversation that I was not the first vehicle they had repaired with this issue. | Crash: No Fire: No | Unknown |
| Oct 2025 | POWER TRAIN,ENGINE | my 2020 High Country Deluxe 6.2 L87 GM Motor: At Every Cold startup, the engine sound is erratic and sounds like metal on metal for internal combustion for approximately 2 seconds until the newly designed two-stage, variable displacement vane-type pump oil sump pump. The biggest issue that I have with this design is, with a 2 stage pump, depending on the engine rpm, according to GM is Possible lower psi to pump the oil to the top end Valve assembly. In addition, the OW/20 oil IMHO is too thin and does not have the Viscosity to lubricate the motor properly. GM Fix (for 2021 -2024 L87 6.2 motors was to change the viscosity to 5W/30 Supercar Synthetic oil, add a leaf to the owners manual to dictate the oil viscosity change and changing the oil cap from 0W/20 to 5W30. 10-speed Hydra-Matic 10L80: Hard upshifts and downshifts intermittently and confusion of proper gears. There is a TSB regarding this specific Valve Body and torque converter issues. Finally: When deactivating DFM Random cylinders as needed by ECM-TCM-BCM, the lifters are staying in the collapsed state and cant return to full height resulting in bent push rods, rocker arm damage, Camshaft damage, crankshaft damage and Catastrophic engine Failure. It now seems that NHTSA has issued a New Federal Probe into the remaining 2019-2021 L87 6.2 motors. | Crash: No Fire: No | Unknown |
