TIRES:TREAD/BELT
While driving home I noticed a vibration in the steering wheel. Once I got home I looked over the tires because I had one start to come apart a month ago so I was worried another one was doing the same thing, and I was correct. The tire has roughly 12k miles on it

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

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.

ENGINE, FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:INJECTORS
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.

POWER TRAIN, VEHICLE SPEED CONTROL, ENGINE
I am writing to express my serious concern and frustration regarding the unresolved recall on my 2020 Chevrolet Silverado 2500 (VIN: [XXX] ). Despite multiple visits to multiple dealerships, I was repeatedly told that the necessary parts to complete the recall repair were on back order and instructed to “wait for parts.” No interim solution or assistance was ever offered. As a result of this delay, my vehicle broke down without warning, leaving me stranded on the side of the road. This created a hazardous situation and significant disruption to my day. To make matters worse, I had to pay out of pocket to have the truck towed to a repair shop in an effort to get it operational—an expense I should never have incurred given the known recall and repeated attempts to have the issue corrected by Chevrolet. I have been a loyal Chevrolet owner and have always trusted the brand for its quality and dependability. However, this delay and lack of proactive support is causing significant inconvenience and eroding that trust. This situation is unacceptable for several reasons: 1.Safety Risk and Recall Obligation: Chevrolet acknowledged the defect by issuing a recall, yet I have been forced to operate a vehicle that does not meet your own safety standards for months. 2.Repeated Service Attempts with No Resolution: I followed the proper process and visited an authorized dealer multiple times, only to be turned away each time with no solution beyond “wait for parts.” 3.Breakdown and Financial Loss: The vehicle failure and subsequent towing expense are a direct consequence of Chevrolet’s inability to provide timely parts or alternative accommodations.

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)

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.

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.

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.
