Due to the Fuel Pump Power Control Module (Part number 13554821) failure, my vehicle stalled in the middle of a turn while pulling a 10,000 pound RV. This caused me to lose both power steering and braking capabilities. From what I gather, this part is part of a "phased" initiative recall (see N252516900 Fuel Pump Power Control Module). This part was seemingly installed in all or most of GM SUVs and Trucks since 2021. Unfortunately, only some 2021-2023 models are under recall due to the "phased" nature of this recall. Meanwhile, all Heavy Duty trucks are driving around on our roadways, highways, and interstates, just like I was, towing heavy machinery, equipment, and RVs because both you and GM are dragging your feet on demanding these flawed modules be removed from these vehicles. In summation, virtually every GM SUV and truck on the road produced since 2021 is a ticking time bomb that could stall at any moment and disable both power steering and braking capability. If thats not bad enough, concerned owners, such as myself, are stonewalled with the words "there is no active recall on your vehicle " both by GM and your very website. The "phased" nature of this recall is unacceptable and is putting lives at risk. Had I been traveling at highway speeds when this failure occurred, while towing a heavy load, with braking traffic in front of me or a sharp turn, I would not have been able to stop or turn. This is an urgent matter and should be addressed accordingly, not in a "phased" manner.
NHTSA complaint #11752781 — an unverified report by a vehicle owner.
The truck kept going into limp mode and when taken to the dealership it was found to have metal in the fuel. According to the report from the dealership they stated that this indicated the injection pump had come apart internally and sent metal throughout the system. It has since been repaired at a high cost to myself. The generation of truck made before mine had a recall for the same thing and I feel that they have not fixed the problem or it wouldn't have happened to my truck. Seems like a manufacturing defect. When in limp mode the truck does not operate at the speed limit required for highway driving. There was no indication prior to the failure.

The high pressure fuel pump “grenaded” while driving on the interstate. Caused an immediate shutdown and barely got off the main lane to the shoulder in extremely heavy traffic putting me, my wife and others in imminent danger. The components were inspected by the dealer mechanic and insurance adjuster and they said that is what happened and that there was no reason for it to have happened. A warning of reduced power appeared about 3 seconds before the truck completely shutdown.

On February 3, 2026, my vehicle was taken to Rick Hendrick Chevrolet of Buford for diagnosis of a fuel system failure. The dealership charged a $235 diagnostic fee and concluded that the failure was caused by fuel contamination from an outside source. Based on this determination, my warranty claim with General Motors was denied and my case (#89096714) was closed. After this determination, the vehicle was transported to an independent diesel repair shop for further inspection. During the initial inspection, the technician removed the intake cover and discovered a large crack in the fuel injector pump. The pump had catastrophically failed and internally disintegrated, sending metal fragments throughout the fuel system. This clearly indicates the contamination originated from an internal mechanical failure of the fuel injector pump, not from outside fuel contamination. The independent technician confirmed that the injector pump failure caused metal debris to spread throughout the fuel system. Additionally, there was a visible leak at the front of the engine, which should have prompted further inspection in that area during the dealership’s diagnosis. It appears the dealership’s conclusion was based primarily on fuel sampling, without performing a full mechanical inspection of the injection pump and related components.

On approximately January 24, 2026 my 2020 Chevrolet Silverado 2500HD equipped with the 6.6 Duramax Diesel displayed an error code (P20B9). This error code was found to be related to the diesel exhaust fluid system specifically relating to "Reductant Heater A Control Circuit/Open." On January 27, 2026, the vehicle was diagnosed at Chevrolet dealership and the following was reported "Diesel Emissions Fluid Tank Remove and Replace - P20B9 SET FOR REDUCTANT HEATER CIRCUIT...COMMANDED ON AND ZERO AMPS..CIRCUITFAILURE... DISCONNECT PUMP MODULE AND BURNED/OVERHEATED TERMINALS..PUMP MODULE AND HARNESS PART OF TANK ASSEMBLY... LABOR TIME ADDED TO PERFORM MALFUNCTION/TAMPER TEST TO CLEAR EMISSIONS MESSAGE...." I found the "burned/overheated terminals" comment to be alarming. I looked into this matter further and found a GM Service Bulletin (21-NA-006) from October 2022. This bulletin identified this issue which contained an image showing burned/overheated terminals. The identified cause within the bulletin states "This condition may be caused by a poor connection at the Emission Reduction Fluid Tank electrical connector." I believe this should upgraded to a safety recall due the the potential of this terminal connection catching fire which could be detrimental for the operator, passengers, property, and the public.
NHTSA complaint #11717543 — an unverified report by a vehicle owner.
Engine started pouring fuel out in large quantities coating the entire chassis. I was lucky, I had planned to go fishing early but had boat issue. Had I gone early in the dark it would have been catastrophic. Large amounts of gas. Pouring out. I'm lucky, when moving the truck my wife noticed the fuel was leaving a trail down the road and started screaming. I immediately parked the vehicle and I am waiting on support to get to dealer. The fuel system is a known defect on 2025/2026 Silverado but not yet identified for this HD 2500 with same 6.6l engine. Entire cab is full of gas fumes. This was extremely scary.
NHTSA complaint #11716637 — an unverified report by a vehicle owner.
first issue was around April-May 2025 when my engine started knocking and burning fuel. Warning light came on and it went right in to the dealer where I have all my maintenance done. They determined that it due to (2) faulty fuel injectors and I had them replaced at that time. In December of 2025 my engine started doing the same thing as before with the knocking and burning fuel and reduced speeds when on the highway so again it went into the dealer. It has since been in there and first was told it was the fuel injector again. They priced out the one was bad and I asked them to replace the remaining 6 fuel injectors so I didn't have this issue again in the near future. They did and the vehicle had the same issues going on. During the next inspection it was determined that the engine needed new rocker arms. These were replaced but this also did not solve the problem and the vehicle would not pass the regeneration on the engine. During the next inspection it was determined that we needed to replace a cylinder and one of the valves. After this was complete they were still having issues and then I was told that the Piston was bad and there are (2) bad valves so I need an entire engine replacement. My truck only has 130,000 miles and has been in the shop for almost 2 months last year from engine issues and it has had all maintenance completed at he same dealership with Records.
NHTSA complaint #11711815 — an unverified report by a vehicle owner.
My 2024 Chevrolet 2500HD Duramax experienced a forced emissions derate event with a speed-limited countdown. The vehicle suddenly lost normal operating capability and became unsafe and undrivable. The truck was disabled in Enid, Oklahoma and had to be recovered and transported to a dealership. Prior to failure, the vehicle showed abnormal DEF/emissions behavior. The failure involves the SCR/DEF emissions system. I later confirmed this vehicle has a completed Product Emissions Recall for SCR Fault Detection. Despite that recall, the emissions system failed and triggered a derate and loss-of-mobility event. The truck is currently at Classic Chevrolet in Owasso, OK for diagnosis.

My pickup truck has a Duramax diesel engine with a CP4 diesel injection pump. That pump has not failed yet in my truck. However it has been known to fail in numerous other GM vehicles with Duramax engines and when it does fail the engine comes to a complete stop and cannot be restarted. This is a potentially hazardous even fatal situation. Repair if the pump fails is very expensive - $12,000 to $14,000 in some cases. I would like GM to replace the injection pump at my dealership to ensure this known failure does not occur. My pickup truck is otherwise in excellent condition.

2024 Chevrolet 2500 HD purchased new. Delivered with missing capless fuel adapter. Pointed out missing capless adapter defect to Chevrolet dealer. Dealer refused to correct defect. When the vehicle ran out of fuel on busy roadway a large quanity of fuel splashed on the owner, the vehicle and the road creating the potential risk of serious fire, injury and environmental hazard. Owner had to purchase the capless adapter from the dealer service department when #1 it should have been included with vehicle purchase #2 Dealer should have corrected this serious safety issue when customer brought it to their attention.
NHTSA complaint #11709190 — an unverified report by a vehicle owner.
I own a 2021 Chevrolet Silverado 2500HD Duramax diesel with approximately 100,300 miles. The truck began displaying a “Service Emissions System” warning and a countdown message that in a certain number of miles the vehicle will be limited in speed (for example to 65 mph). GM’s own Duramax diesel owner’s supplement explains that when a “Service Emission System” message appears it is accompanied by a distance-until-speed-limit countdown and that the truck will progressively limit speed first to about 65 mph and then to about 55 mph if the condition is not corrected, telling the owner to see the dealer. This creates a safety risk because the derate can occur while driving on highways or rural roads, where an unexpected limit on maximum speed can interfere with merging, passing, and keeping up with traffic. This is our only vehicle, and we must use it for important medical appointments, including cardiology and surgery-related visits. The condition started only about 300 miles beyond GM’s 5-year / 100,000-mile powertrain warranty. I opened a case with Chevrolet / GM Corporate (Service Request No. XXX) and took the truck to Sons Chevrolet in Columbus, Georgia on November 17, 2025 for this issue and a rear wheel lockup recall. The dealer kept the truck from about 9:00 a.m. to 3:00 p.m. and indicated they might need to keep it for at least two more days, but I was not given a clear written explanation of the diagnostic trouble codes or a firm repair plan. Because GM’s own manuals describe this “Service Emission System” message together with speed-limit countdowns, and because the vehicle can actively limit speed on the road if the fault is not resolved, I am concerned this represents a broader emissions/derate defect on late-model Silverado HD Duramax trucks. I request that NHTSA review similar complaints and consider whether further investigation or a safety recall is warranted.

The truck randomly shuts off whether just running or driving, the fuel pump fuse blows, as long as we switch the fuses it starts right up and runs again, sometimes it happens several times a day, other times it doesn't happen for a week or two. When driving it shuts down without warning and lose of everything.

The fuel pump inside the tank shorted out and left us stranded. This is the same pump that was used on the the 2022 Duramax systems however they upped the fuel pressure on the 2024 refresh and it has become a known problem of shorting out.

While driving on the freeway in a construction zone, I smelled a burning oil smell. I considered the possibility it was in relation to road repairs being done (roads being repaved, ie tar resurfacing). I was cut off by another vehicle and depressed my brakes and I saw a poof of smoke over the front passenger area near tire. I noticed all of my gauges were in the normal ranges (temperature, battery voltage, etc.) In less than a minute my truck went into limp mode and advised it had a DEF system issue and it would be limited to a set MPH and a set number of miles. Check engine light came on and another driver alerted me that the underneath of my vehicle was on fire. I pulled over to the side of the highway and my truck became engulfed in flames in. Truck is under factory warranty, unmodified, never been in an accident and has had all recommended services performed at local dealership. There was a significant amount of traffic and luckily I did not collide with anyone or set neighboring dry grass field on fire. Fire department responded and extinguished the fire, but it is a total loss. Insurance company has been notified, and vehicle will be available for inspection by appropriate agencies. While local law enforcement did respond, they did not take a report because I didn't hit anything, and the only property damage was my own. (There is documentation of the event, but just dispatch notes.) Prior to the situation above the truck had been at operating temperature for at least 20 minutes and I had traveled for about 20 miles on the highway. The total distance traveled from when I smelled the burning smell was maybe 1.5 miles.

With 19,000 miles on my Silverado 2500 HD I was traveling down a hill towards a stop sign at a T intersection. About 100 yeads from the stop sign I had many flashing errors on the dash, very little brake and very little steering. The engine just shot off. Fortunately I was able to stop the vehicle right at the stop sign while traffic from right and left had no stop sign. The truck would not start after. It did have electrical power. I tow was needed. The next day the Chevy dealer did find a bulletin for a wire in the engine compartment chaffed. Symptoms were the same as what I experienced. Repair was made. Bulletin #24-NA-124. There is no doubt a bulletin should be issued but I believe this is a real safety issue with the engine just randomly shutting off leaving no power to brakes and steering. Had this happened while I was towing our camper I would not have stopped and t boned another vehicle causing damage and no doubt injury to others and myself. If traveling on an interstate at 70 MPH this could have been even worst. This is a known problem and should be a recall and not just a bulletin. Thanks.

The contact owns a 2015 Chevrolet Silverado 2500. The contact stated while driving approximately 65 MPH, the vehicle stalled. The contact stated there was no warning illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the high-pressure diesel fuel pump had failed, and the entire fuel system needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 190,000.

Driving down the road in heavy traffic and had complete engine failure due to loss of fuel. Diagnosed as fuel control module. I have seen where GM recalls have been made for similar issues. This put me in danger of collision. Truck is at the dealer and will cost $957.00
NHTSA complaint #11663890 — an unverified report by a vehicle owner.
I was driving my truck and lost full power to the truck. Which happened as I was pulling out of a parking. The truck went into a limp mode. With the truck losing full power, it put my child and I into a safety risk. The truck got repaired at the dealership. The dealer was able to reproduce the issue. The truck was inspected at the dealership. Warning system did come on saying speed would be limited if (roughly 150 miles to a max 65mph). When I called another dealership, they said this was a normal thing for these trucks and chevy hasn't fixed it. I feel like if its a known issue with the wiring becoming free, why would they not proactively fix this issue before someone gets hurts from thinking they have the power to drive. The dealership that I took this too knew where to look right away as this is common.
