The engine cut itself off and shifted itself into neutral as I was slowing down and turning left into the gas station. It is available for inspection. My safety was at risk because had this happened on a legal road way, it could’ve caused someone to rear end me or t-bone me because I would’ve unexpectedly stopped, or the power steering may not have worked and I could’ve run into something. It has not been reproduced by any mechanic, only me. It has happened to me only twice within a 400 mile span. It has been inspected by a GM dealership twice now and is currently still at the dealership. There were no warnings of any kind before, during, or after the occurrence.
NHTSA complaint #11763649 — an unverified report by a vehicle owner.
My 2021 Chevrolet Silverado 1500 RST with the 6.2L engine experienced an engine seizure. The engine was replaced by a Chevrolet dealership under a GM safety recall. Immediately after picking up the vehicle following the recall engine replacement, the truck stalled while still in the Chevrolet dealership parking lot. There was no warning before this first stall. We continued our trip because we did not realize at the time that the stall could indicate a problem following the engine replacement. During the drive from [XXX] to [XXX], the problem continued. In [XXX], the check engine light illuminated and the truck began malfunctioning. The vehicle subsequently stalled again. The problem continued after returning to [XXX]. A Chevrolet dealership in [XXX] inspected the vehicle and reproduced/confirmed a problem involving the camshaft position sensor wiring/connector. The dealership demonstrated the problem by manipulating the connector/wiring and recorded a video of the diagnostic procedure. The vehicle is currently at the Chevrolet dealership and is available for inspection. The affected component should also be available for inspection because it has not yet been repaired. The [XXX] dealership has characterized the wiring/connector condition as normal wear. However, the first stall occurred immediately after the GM recall engine replacement, while the vehicle was still on the repairing Chevrolet dealership's property. Unexpected engine stalling creates a serious safety risk because the vehicle can lose propulsion without warning while driving, including at highway speeds or in traffic. I am concerned that the camshaft position circuit/wiring/connector problem may be associated with the recall engine replacement procedure or replacement engine. I am requesting that NHTSA investigate whether other vehicles receiving this GM 6.2L engine recall remedy have experienced similar camshaft position circuit failures or unexpected stalling after engine repair.

NHTSA complaint #11763216 — an unverified report by a vehicle owner.
I experienced a crankshaft bearing failure while driving my 6.2L V8 Chevrolet Silverado on the highway / freeway. Thankfully I was able to exit highway / freeway to avoid a car collision due to loss of power. My truck was towed to a certified Chevy dealer. This is a known issue for 2019-2026 6.2L V8 L87 engines. The truck was previously inspected by a certified Chevy dealer for prior L87 engine recall. It passed and they changed the oil type to 0w-40. Prior to this event, my truck was at the dealer for a low oil pressure issue / oil pan replacement. I picked it up from the dealer after the vehicle was repaired and drove it for about three days and then experienced the crankshaft bearing failure. No warning lamps illuminated prior to failure. My truck is currently at the dealer waiting for a new engine.

Catastrophic Engine failure - Chevy, Silverado 1500, Yr: 2023; Odometer: 33,183: On 8/16/2026 we were traveling down a busy highway towing our camper and the engine completely stopped, no propulsion, no warning lights, no check engine lights; complete failure; we had to coast to side of road. The only thing that indicated a problem is that we started hearing what sounded like marbles rattling, it wasn't loud but noticeable. We pulled over at gas station to check oil, even though we just had the oil changed for maintenance on 7/17/2026 (Odometer: 32,587). Everything checked out ok; however, the marble sound became louder; then within 5 minutes of leaving the gas station, we lost all engine propulsion; the engine completely shut down. Our safety was put at risk as we had no truck engine and were towing a camper on a busy highway; and had to try and coast to a safe location on side of road; miles away from home. We had to call a tow truck to come get us and unfortunately, they could not help us with our camper so then had to call our son to come with his truck to get our camper and us home safely. The tow company also had a difficult time getting the truck into neutral to tow. The truck was towed to our hometown Chevy Dealer. The dealer said that they were not going to diagnose the problem and instead are ordering a new 6.2 engine; same as the 6.2 that failed. We asked if this would fix the problem and they said there were no guarantees as it is the same engine with the same problem. Prior to this event, we received a recall in Sep 2025 and an engine inspection and oil change was performed on 9/12/2025 (Odometer: 25,751); we were told that our engine was ok. As of 9/3/2026; we have been without our vehicle for 17 days.

Vehicle sent alert on phone saying battery critically low, then the vehicle started having fuel gauge issue and started lurching. Shut the vehicle down saw a P129F in the alerts. Checked battery vehicle was a no start. Luckily near a shop so it wasn't catastrophic and was able to r eplace the fuel pump control module and it instantly started. This part NEEDS to be recalled it is a safety hazard that chevy does not aknowledge

AFM causing engine tick. I am reporting a radiator failure on my 2019 Chevrolet Silverado 1500 equipped with the 6.2L V8. The vehicle developed an active coolant leak from the radiator assembly. The coolant reservoir level dropped significantly after normal driving, and coolant was visibly leaking and collecting underneath the vehicle. The truck initially began running warmer than normal, approximately 215–220°F, before the leak was fully identified. After topping the system with the correct DEX-COOL coolant, the coolant level continued to drop and an external leak became clearly visible. The vehicle was subsequently parked to avoid engine overheating or further damage. The original radiator carries GM part number 84152439. I have since been advised that the current GM replacement radiator is part number 85575815. I was also informed by GM dealership personnel that radiator failures involving this application are currently being investigated. My concern is that a sudden radiator failure can result in rapid coolant loss and overheating, potentially causing engine damage or vehicle disablement while driving. This is particularly concerning because the temperature gauge may initially remain near normal even while coolant is being lost. I am requesting that NHTSA review radiator failures on 2019 Chevrolet Silverado 1500 models, particularly vehicles equipped with the 6.2L engine and heavy-duty/enhanced cooling package, to determine whether there is a pattern of premature radiator cracking, tank/seam failure, or other coolant-loss defects that warrant a safety investigation, service campaign, or recall.

Check engine light repeatedly comes on. Take it in, multiple Chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I Routinely take care of vehicle (oil changes, tire rotations and service when needed) This truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from AutoNation in 12/2023.

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.

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)
