| Oct 2025 | POWER TRAIN | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that once the vehicle had warmed up, while driving at speeds of 50 MPH or higher, the vehicle shuddered abnormally while depressing the accelerator pedal, and the vehicle became difficult to steer. There were no warning lights illuminated, or codes displayed. The vehicle was taken to the dealer, who diagnosed that the torque converter and reaction carrier had failed. The transmission was scheduled to be replaced. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 61,200. | Crash: No Fire: No | 61,200 |
| Oct 2025 | STEERING,UNKNOWN OR OTHER | Without warning (no warning lights or previous mechanical indications) the power steering failed making it extremely difficult to turn the steering wheel. Fortunately this happened while I was parking and not on the highway. The truck had approximately 48,000 miles on it at the time. (8/30/25) Repairs required replacing the rack and pinion steering and a heavily corroded "grounding strap". Repair cost was appx $3500 | Crash: No Fire: No | Unknown |
| Oct 2025 | POWER TRAIN,UNKNOWN OR OTHER,ENGINE | Summary: While driving, the transmission intermittently fails to shift and the truck has locked up and screeched to a complete halt approximately four times, creating a sudden stop/near rear‑end‑collision risk. Details & timeline: First symptoms were around 55,010 miles. On 10/13/2024 the Chevrolet dealer performed “SERVICE TRANSMISSION GM” (fluid & filter), but the condition continued. In April 2025, a shop documented DTC P0700 & P2727 (pressure‑control solenoid), burnt transmission fluid, and clutch material in the pan, and recommended replacing the transmission, transmission cooler, and cooler lines. Earlier, the transmission control module was reprogrammed, and oil cooler lines were replaced, but the truck still intermittently fails to shift while driving. The check engine light has illuminated during some events. Engine safety concern: During the same period the engine oil was found very low/“no oil on dipstick” with no external leaks; an oil‑consumption test was recommended, raising concern about internal engine damage and possible contamination from the transmission failure. Safety impact: The lock‑up / abrupt stop events occurred while the vehicle was in motion at approximately [~speed and road type, e.g., 35–55 mph on city/secondary roads], forcing hard braking by vehicles behind me. This presents a risk of sudden loss of propulsion and crash. Frequency: About four lock‑up events so far; shifting failures are intermittent and ongoing. Current status: Vehicle at ~73,000 miles. A Chevrolet dealer is being asked to perform a factory diagnosis and to submit a manufacturer goodwill/warranty review. | Crash: No Fire: No | Unknown |
| Oct 2025 | STEERING | Just recently my power steering started cutting in and out in parking lots. I have seen that there is a ongoing investigation into steering problems with these trucks. I have not took it to a shop, because it just started and has only done it in parking situations. There are no lights or warning codes on the dash. It was about two weeks ago that it started. The vehicle is available for inspection upon request. I just would not like to experience it failing on the road. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE AND ENGINE COOLING,POWER TRAIN | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle was shaking and vibrating abnormally. There was no warning light illuminated. The contact stated the failure was a recurring failure. The vehicle was taken to a local dealer and the contact was informed that the oil level was low, and oil was added. The dealer had not diagnosed the vehicle. The contact stated that the failure reoccurred. The contact had been checking the oil level and was constantly adding oil. The contact stated that the same dealer had changed the spark plugs and fuel injectors in January 2025. Recently the contact was unable to start the vehicle, and the vehicle was towed to the same dealer. The vehicle was not diagnosed; however, the dealer advised that the failure might have occurred due to a failure with the transmission. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 136,888. | Crash: No Fire: No Towed | 136,888 |
| Oct 2025 | POWER TRAIN | Dear NHTSA Office of Defects Investigation: I am filing this formal complaint regarding General Motors' failure to provide a timely remedy for safety recall XXX and GM's inadequate response to a catastrophic transmission defect that has affected my vehicle twice, resulting in complete transmission lockup while driving at highway speeds. *SAFETY INCIDENT HISTORY My 2020 Chevrolet Silverado 1500 has experienced the transmission control valve defect described in recall XXX on two separate occasions, both while driving at approximately 65 mph on the highway. Each incident resulted in complete rear wheel lockup, creating an immediate life-threatening situation. Following the second failure, I had the vehicle towed to Huffines Chevrolet Plano [XXX] ) on August 18, 2025. UNREASONABLE DELAY IN RECALL REMEDY As of today, October 6, 2025, my vehicle has remained at the dealership for 49 days with absolutely zero action taken toward repair. The vehicle has not been evaluated, diagnosed, or repaired. The dealer states they have only one transmission technician to handle the massive volume of recalled Silverado trucks affected by this defect.

| Sep 2025 | POWER TRAIN | 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.

| Sep 2025 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,ENGINE | Truck experienced reduce power mode. Took to have codes ran and it showed 24 separate codes when engine light comes on. While riding down the road, truck will go into reduce power mode, shift automatically into 4x4, and several other notifications will appear. Taking to dealership and was told the electrical wiring harness was shorting out causing this issue. Cost around $700 for repair, happened one month later, took it back and no charge for the 2nd time. It is currently in reduced power now. Dealership stated to replace the wiring harness would cost over $3,000. Dealership stated this was a manufactures defect, but no recall was issued so all cost is on the owner. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 70 MPH and depressing the accelerator pedal, the engine failed and shut off independently. An independent mechanic and dealer were contacted. The vehicle was towed to an independent mechanic, and the contact was informed that the crankshaft had melted. The vehicle was then towed to dealer, where it was diagnosed and determined that the crankshaft had melted and there was a rod bearing failure. The engine was replaced, and the vehicle was repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was 76,000. | Crash: No Fire: No Towed | 76,000 |
| Sep 2025 | POWER TRAIN,ENGINE | After completing a GM assisted engine rebuild the transmission oil pump is failing and transmission shifting era tic. | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN,VEHICLE SPEED CONTROL,WHEELS | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE | Coolant control valve failure. Dealer inspected vehicle and it was confirmed that it needed to be replaced. Check engine light came on fan started spinning at a high speed and the vehicle went into low power mode. When I spoke with the dealer, this is a known issue so much to the point where the cooler control valve is on backorder and I’ve had to wait for over a month now. Projected cost to replace with labor is over $3000. | Crash: No Fire: No | Unknown |
| Sep 2025 | FUEL SYSTEM, GASOLINE,ENGINE | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at a moderate speed, the fuel warning light had appeared on the instrument panel. After fueling the vehicle at a gas station, the vehicle began to hesitate while depressing the accelerator pedal, with several warning lights, including the "Engine Power Reduced" and "Service ESC" illuminated. Due to the failure, the contact had the vehicle towed to a dealer. The dealer informed the contact that the starter needed to be replaced because the vehicle had failed to start. The mechanic performed a diagnostic test and discovered that the fuel injectors were defective and leaking fuel into the engine. The mechanic diagnosed the vehicle with engine failure and provided the contact with an estimate for repair. The manufacturer was notified of the failure but offered no assistance. The contact was then referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 68,000. | Crash: No Fire: No Towed | 68,000 |
| Aug 2025 | POWER TRAIN,ELECTRICAL SYSTEM | 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) | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | STEERING,FORWARD COLLISION AVOIDANCE | Power steering locked up. Dashboard warnings "Service Power Steering Drive with Care, Service Trailer Brake System and Driver Assist Disabled" | Crash: No Fire: No | Unknown |
| Aug 2025 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |

| Aug 2025 | POWER TRAIN | 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. | Crash: No Fire: No Towed | 58,000 |
| Aug 2025 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | While driving the active fuel management changed my truck from 4 cylinders to 8 cylinders. This is when I heard a loud bang and a bunch of lights came on the dash and my truck started shaking and shuttering. I was able to regain control of it, but I came close to crashing. I now require a whole new engine at 100000 miles. After talking to multiple shops this ks a known issue. While they dont always catastrophic fail, mine did and almost cost me to crash. This is a serious safety concern. | Crash: No Fire: No | Unknown |
