NHTSA complaint #11758587 — an unverified report by a vehicle owner.
While driving at highway speed, my vehicle developed a serious transmission problem. At approximately 75 mph, it suddenly lost the ability to maintain speed and dropped to about 55 mph despite throttle input. Engine RPM increased significantly and the vehicle had greatly reduced propulsion. Normal operation temporarily returned after the vehicle was shut off and restarted. The vehicle has also experienced harsh shifting, vibration, limp-mode behavior, a check-engine light, and I reported a momentary wheel-lock event. These symptoms create a safety concern because an unexpected loss of propulsion or abnormal transmission behavior at freeway speeds can increase the risk of a collision. The vehicle was inspected by an authorized Chevrolet dealer. The dealer documented transmission-related diagnostic codes including P0700, P0970, P0968, and P0711. The dealer's repair order specifically referenced GM program N242454441-03, described transmission control-valve wear and pressure loss, and recommended replacement of the valve body. A separate repair estimate included the valve-body assembly and related transmission service parts. Despite the dealer recommending valve-body replacement, GM/dealer coverage was denied primarily because P0747 was not present at the time of diagnosis. I am reporting this because I am concerned that transmission control-valve/valve-body deterioration may cause harsh shifting, reduced propulsion, limp mode, or other safety-related symptoms before or without P0747 being stored. I am asking NHTSA to review whether vehicles with the same underlying valve-body failure may remain on the road because the specific qualifying diagnostic code is not present during a dealer scan. The vehicle and transmission are available for further inspection if requested.

Main bearing failure at highway speed. Engine replaced by GM under warranty. Vehicle had the recall service done prior to the failure, the recall test and different oil was inadequate to predict or prevent this failure. Vehicle was serviced by the dealer for all oil changes on time.

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that NHTSA review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

NHTSA complaint #11756231 — an unverified report by a vehicle owner.
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 MPH and attempting to accelerate to 55 MPH, the engine started choking, and the vehicle lunged back and forth, and slowly lost drive power. The vehicle was driven to a local certified mechanic while driving at slower speeds. The certified mechanic diagnosed the vehicle and determined that the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems had failed and caused the engine failure. The vehicle was not repaired. The mechanic informed the contact that Chevrolet vehicles with similar engines were known for engine failure. The manufacturer was not informed of the issue. The failure mileage was approximately 119,000.
NHTSA complaint #11755970 — an unverified report by a vehicle owner.
Multiple times the truck has stopped running while driving. Once one the highway, once in an intersection, another time in a parking lot. It has not started when I have tried to turn it on. All the times I have called AAA. They have checked the battery and there is no battery issue. Twice AAA has come out, once the police have come and sat behind the truck to keep me safe. After about 10 minutes of the sitting with the truck off I can restart it and drive. Upon research, other Chevy trucks of similar age have a recall for a failed fuel pump module. This is the issue. If it is a known issue, and causing a dangerous situation it should be recalled on all trims of Chevy trucks. I will be getting this fixed, but don’t feel I should incur the $1,000 expense for a known defect.

On August 22, 2025 the malfunction indicator lamp (code: P146B Evap. purge pump) illuminated with no noticeable change. Ran codes at auto zone which stated engine failed and emissions not ready. August 25, 2025 drove to certified Chevy dealer dropped off vehicle and showed the service advisor the fix finder test results from auto zone as well as the illuminated indicator lamp (check engine light). August 26, 2025 picked up my vehicle with receipt stating "found dtc's P146b and P1467 stored in ECM (engine control module) for evap purge pump fault. inspected evap canister for any signs of fuel and none were found. replaced evap purge pump per special policy #N232395310. Cleared dtc and road tested vehicle to verify repair". September 9, 2025 my engine indicator light illuminated and my engine entered limp mode, a safety feature which reduces cylinder output/capacity. September 12, 2025 while in limp mode, I returned to the service dealer and informed them of the reduced power (limp mode) and my confusion as the second engine symbol that has been illuminated is in a different area than the first and my truck has ONE engine. (editor note: malfunction indicator lamp is for the emissions). My original transmission (8L90) was replace, because my vehicle was under power train warranty and the service advisor took it upon himself to approve the disassembly of my running, in good condition 8L90 transmission without consulting me or my approval. the 8L90 was "discontinued" for the 2020-2022 years without recall come to find out (sarcasm). I now have a new transmission (8L86-85) with the "special coverage" part (#N232395310) still connected, only now I have NO additional powertrain coverage for a new transmission, but the "special coverage" originally issued in 2023, BY MAIL, for 15 yr/150,000miles has extended two years plus mileage. (15 yr / 152,955) .The "special coverage" part should NOT affect the engine! Engines produce power/HEAT not CO2 . Sarbane - Oxley Act.

Was making a left turn with a left turn street light green for me to turn across an intersection. Pickup stalled in the middle of the intersection and would not start. With the help of another person we manually pushed the pickup out of the intersection and onto another side street. I received an email at that exact time from General Motors showing a code of P129F which is the Fuel Pump Power Control Module. I am a [XXX] man stranded in 90 degree heat with no AC or shade to get under. My safety was put at risk in the above instance but more so if I had been entering IH 10 into traffic traveling 70MPH and my truck had just stopped running without any warning. This is a known problem as described in GM Service Bulletin 24-NA-139 with both the NHTSA and DOT. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11755034 — an unverified report by a vehicle owner.
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle lost power and stalled in the middle of the road. The check engine warning light was illuminated with the message "Fuel Low" displayed. The vehicle was pushed to the side of the road, and the contact later returned to the vehicle and added a small amount of fuel to the fuel tank. After starting the vehicle, the vehicle operated normally and was driven to the residence and parked. The following day, the vehicle was started, and the fuel gauge indicated that the fuel tank was half full. The vehicle was driven to the local dealer, who diagnosed the vehicle with fuel pump power control module failure. The contact was informed that the fuel pump power control module needed to be replaced. The fuel pump power control module was replaced. The cause of the failure was not yet determined. The manufacturer was not contacted. The failure mileage was 71,969.
NHTSA complaint #11753588 — an unverified report by a vehicle owner.
Description of Problem: While driving, the engine intermittently revs on its own without any input from the accelerator pedal. During these episodes, the vehicle also shakes/vibrates noticeably. This has occurred [once / multiple times — specify frequency, e.g., “several times over the past X weeks”]. The engine revving is not consistent with normal acceleration and appears unrelated to throttle position. The shaking is felt throughout the cabin and is most noticeable [at idle / at speed / when the revving occurs — specify if known]. Safety Concern: This creates a risk of sudden, unintended changes in vehicle speed or loss of control, particularly if it occurs in traffic, while merging, or at highway speed.

On XXX I was driving from [XXX] to my sister's house in [XXX]. I was relocating to [XXX] for a job. I was pulling a U-haul trailer (6x12) that contained significantly less weight than the truck can handle. About halfway there, on back roads, the truck suddenly slowed significantly and the gas pedal was unresponsive. The light in the dashboard read Reduced Acceleration - Drive with caution. Pulled over, turned off truck, opened driver side door, to reset the truck (read this on google). We had to do this a couple times, because it would just go back to that behavior after a bit. We made it to my sister's house to stay the night. In the morning, XXX, I called the local Chevy Service Dept in [XXX] and asked if I could bring it in, I described the problem. During the drive to the shop, the same issue occurred. Upon arriving at the service dept, the Trailer app was giving a warning that the load may be heavier than max. Which cannot be true. The dealer techs said they had never seen anything like it before, but they seemed to know what to look for. They then informed me that they could not loan me a car because I was traveling out of state. I had a deadline, so my only option was to rent a U Haul box truck, unload the back of my truck into it, hitch the trailer I already had to it, and drive to [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11750668 — an unverified report by a vehicle owner.
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.

Truck stutters and idles terrible. Vehicle warning light keeps saying, reduce acceleration and drive safely. Two years ago an injector went bad, and it was fixed. 6 months ago, we had it in the shop, of course still under the 60k mile warranty. Said it was fixed, it wasn’t. Just had it back there, and they replaced the the torque converter. Shaking stopped for a month. Now it is even worse. Believe it is faulty injectors. Sadly, we’re not passed the 60k warranty period and feel unsafe driving our truck which we need every single day. Truck is nearly paid off and feel like we got jipped as this truck continues to have problems after problems

Truck continues to shutter after having the torque converter replaced and the 2nd injector replaced. Been in the shop several times over the last few years, and still giving warnings on the dash saying, reduce acceleration drive safely. Feel like we just got a terrible vehicle. Almost paid off, and it’s just unreliable. Sadly we need this truck every single day, and the local dealerships have now pushed the problem out so far that we’re passed out 60k warranty period.

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.
NHTSA complaint #11747650 — an unverified report by a vehicle owner.
Fuel regulation module K111 part number GM13540028 failed and when this part fails the truck is stuck where it is. The brakes are locked, the truck cannot be started or put in neutral. If the truck stops on the road or freeway you are completely stuck where you are in the middle of traffic. This part fails often and failure leads to a very dangerous situation.
NHTSA complaint #11745264 — an unverified report by a vehicle owner.
On June 18, 2026, my 2022 Chevrolet Silverado 1500 with the 5.3L V8 engine and approximately 41,000 miles suddenly stalled and died while driving in traffic and would not restart. The vehicle had to be towed to a Chevrolet dealership (Starling Chevrolet in Mt. Pleasant, SC). The service manager ran a diagnostic and identified the Fuel Pump Control Module (FPCM) as the likely cause of failure. This appears to be a known and widespread issue affecting newer Silverado trucks. The sudden stall while driving with no warning created a dangerous situation in traffic. The vehicle is currently at the dealer awaiting repair under the powertrain warranty.

Vehicle would not start while on vacation. Called a tow to take to GM dealer. Turns out the fuel pump control module was bad. Some 2023 with a 5.3 had recalls. I was told my bin didn’t qualify so GM told me to contact you.

Complete engine failure on the highway, compete engine and power lockup, towed back to dealership where complete engine lockup was confirmed. No prior issues, no other damage contributing to failure. Claims not to be covered under current recall, advising the recall be extended to all 6.2 19-04 Chevy models as I experienced the same engine failure as recall states.
