VIN: [XXX] Component: Powertrain / Transmission / Recall Remedy Description of the Problem: Recall remedy applied in June 2025 failed. Transmission subsequently failed. On August 25, 2025, a Mangino Chevrolet technician confirmed in writing that the failure was -??related to the recall that was previously performed.-?? My truck was previously in GM-??s care at Van Bortel Chevy (Nov-?"Dec 2024), after the recall officially opened on 10/24/2024, but the remedy was not applied at that time. I was forced to continue driving thousands of miles with the defect still present. Despite the written admission that the failure is recall-related, GM Customer Care has only offered a 50/50 split on the transmission replacement (my portion -?? $3,950.34 + tax) and is now attempting to reframe the issue as a maintenance problem. Transmission fluid service intervals are not the cause here -?" the federally mandated recall remedy failed to prevent the very failure it was supposed to address. This situation has left me without a safe, reliable vehicle. GM has acknowledged the recall remedy failed but is refusing to take full responsibility. I am requesting that NHTSA investigate GM-??s handling of this recall remedy failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

With only 70,000 miles on the truck it started to have a hard shudder and wheels locking up. During the wheel shudder it would shift hard as well. We took it to a shop and they said it was our Transmission control module and that the transmission had metal shavings and would fail soon. They also said doing any service to these transmissions can cause failure.We were informed that the dealership is aware these transmissions are all failing. The cost to replace is over $6,500. The dealership should have to do an official recall for this. After some research i found that the dealership has acknowledged the issue by replacing the TCM and uploading new software to put the transmission into a fail safe instead of putting in a new transmission. The issues that the failure causes has made thousands of people have to get new transmissions before the service is even due. A quick search on Google states that 461,000 vehicles were effected and that a recall has been issued, but it has not been officially issued. We need a new transmission and should not have to pay for it on a truck that is so new and serviced timely.

The transmission skips and has trouble finding gears. This causes the truck to vibrate, be slow to accelerate, or lurch occasionally. The decrease in vehicle responsiveness and unpredictable behavior make the vehicle drivable, but less safe.

am writing to formally report a transmission failure in my 2020 Chevrolet Silverado 1500 and to request your assistance in addressing this issue. I purchased the vehicle on September 2020from Suburu Cobband it currently has approximately 143,000 miles on the odometer. Recently, the truck began experiencing serious transmission-related issues, including total failure. These issues developed without warning and have rendered the vehicle unreliable and unsafe to operate. After inspection by ALM Chevy, I was informed that the failure likely stems from a known issue with the torque converter or transmission valve body -?" problems that have been widely reported in 2020 Silverado models with the 8-speed automatic transmission. I have also learned that GM issued a recall for certain 2020-?"2022 models due to excessive transmission valve wear, which may cause the rear wheels to lock up. I am concerned that my vehicle may fall within the scope of this recall or a related Technical Service Bulletin (such as TSB 21-NA-199). Given the seriousness of the failure, the relatively low mileage, and the widespread nature of these transmission problems, I believe this may be a defect in materials or workmanship. I respectfully request the following: Confirmation of whether my vehicle is subject to any open recalls or service bulletins relating to the transmission. A warranty or goodwill repair of the transmission or related components. If parts are unavailable, an estimated timeline for repair or alternative transportation options. I am attaching copies of my repair estimate, service records, and proof of purchase. Please advise me of the next steps and whether further documentation is needed. Thank you for your attention to this matter. I look forward to a prompt resolution so that I may safely return my Silverado to the road. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to bring to your attention an issue I've been experiencing with my truck's transmission. Recently, the transmission failed due to a torque converter issue, which has caused significant disruption for me. From my understanding, this is a known problem that hasn-??t been adequately addressed by GM. As I'm currently in the process of getting the transmission rebuilt, I believe it is only fair that I should not have to bear the costs associated with this repair. I would appreciate it if someone from GM could reach out to discuss this matter further. Thank you for your attention, and I look forward to your prompt response.

The transmission is locking up at speed causing a significant jump/ lurch in the rear end momentarily that sudden causes lane change. The dealer is telling me this is related to the transmission valve body recall however I received no warning and my truck has never gone into limp mode even though the recall remedy was supposed to provide a 10k mile warning. It would seem the determining factor is not being measured correctly or there are other contributing factors that are not being considered. This seems very dangerous and happened six times over the course of five miles before I could get the truck home and off the road.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 70 MPH, the transmission independently shifted to 4-WD. No warning lights were illuminated. The contact stated that the vehicle decelerated to 55 MPH, and the rear wheels locked up. The contact stated that the failure reoccurred, the rear wheels locked up, and the vehicle went sideways. The vehicle was almost involved in a crash. The contact-??s wife, small children, and grandchildren were occupants of the vehicle during the failure. The vehicle was driven to the residence. The contact stated that the vehicle failed to exceed 50 MPH while driving. The contact's wife was afraid to drive the vehicle. The OnStar system retrieved DTC: P0708 (Transmission Range Sensor Circuit High Input). Additionally, in November 2024, an unknown recall repair was performed to update the power train software. The dealer was made aware of the failure. The vehicle was scheduled to be diagnosed at a later date. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 58,000.

Rear wheels of vehicle locked up momentarily mutliple times while driving between 45 and 65 miles per hour. Originally happened multiple times while towing a travel trailer but subsequently happened again with no trailer being towed. No warning lights or other sign of a problem leading up to any of the malfunctions. After locking up for approximately a quarter to half a second, the wheels release and the truck drives normally. Sudden wheel lock up could lead to loss of control or cause a vehicle to collide with the back of affected vehicle. Issue was reproduced by dealer service department and they recommended a new transmission valve body. This seems to be related to the recall for the transmissions on the diesel models of this truck but the gas trucks were excluded from that recall.

Initially, turbo charger issues. Dealer after 2 weeks corrected issues with the turbo charger. We were provided loaner. Dealer took 28 days, the second time, to supposedly remedy Transmission/shifting issues. First we were told it was a valve port body. Then we were told they had to remove the pan, etc., all part of the process. Then the parts were on backorder. Finally, at the 11th hour, they installed a rebuilt transmission. Without a loaner for 2 weeks. Got the truck back and within 24 hours, the truck suddenly lost power steering while driving around curve at aprox.30 to 35 mph., check engine light on, power steering light on, trailer brakes warning light on, etc. Had it towed back to dealer in the morning and told it would be a priority. Called at 5pm. Truck has not been seen. It's not a car. It's a work truck. Seems the dealership is swamped with silverado trucks with similar transmission issues waiting for valve ports. No loaner vehicles to be had the second time after 2 weeks. Not sure what they will tell us tomorrow.

I had the lifters and camshaft fail in my truck as a result of the faulty fuel management system GM put in these trucks during these years of manufacturing. I was driving my kids to an appointment when they failed in the middle of the highway, leaving the truck unable to run. I have reported the problem to the dealer as well as reported to GM directly. I have spoken with 3 different garages, all of which have made it a point to tell me this is a common issue in these trucks. Prior to this happening, there were no lights on to warn me of this problem. The repair cost is $12,000 and that is to put the same parts in the failed the first time. I don-??t know many consumers that can afford the costs of these repairs when GM knows this is an issue but refuses to do anything about it.
