2023 Chevrolet Silverado 1500 Fuel system Problems

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.

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)

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.

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.

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. while accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into Neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated P0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them

I'm reporting a 5mpg fuel economy reduction immediately following the 6.2L L87 engine recall (NHTSA #24V795000). I use 93 octane and monitor my fuel mileage consistently. I bragged about my fuel economy in my 6.2l until after the recall was applied. This is going to cause a financial hardship as I'm on fixed income after Servicing 29 years in the Army and 100% disabled. There is no other reason my mpg should have changed as my driving habits have not.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that on two separate occasions while hauling the camper, the "High Diesel Exhaust Fluid", Exhaust Fluid Range", and "Fill DEF (Diesel Exhaust Fluid) Now" warning messages were displayed on the instrument panel. The messages indicated that the Diesel Exhaust Fluid was low and needed to be replenished. The contact stated that the failure caused the instrument panel to freeze and not operate as needed. Upon attempting to refuel the vehicle, fuel failed to enter the fuel tank since the diesel tank was full. The vehicle was taken to a dealer, where the contact was informed that the failure was an electrical glitch and that there were no issues with the Diesel Exhaust Fluid system. The contact was also informed by the dealer of Technical Service Bulletin: 22-NA-150, which the contact related to the failure. The dealer reset the vehicle, which caused the instrument panel to return to normal operation. The manufacturer was then notified of the failure, and the contact was informed that vehicle was not included in the TSB. The contact was given a case number and was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 55,000.

Loss of engine propulsion while traveling down a highway towing a #5000 trailer at 65 mph. Less than five miles before the failure the vehicle experienced a momentary downshift of the transmission such as you would experience while climbing a hill or extreme headwind. No warning lights were present at that time or at any time prior to engine shutdown. Upon failure panel indicated "Press Engine Start" and transmission indicated "Park" though we were rolling/coasting at over 60 mph. Realizing that we had lost propulsion I guided the vehicle to the shoulder and stopped. Solid check engine light on at this time. Depressing the "Start" button while stopped would not start or crank over the engine. Boost box would not crank engine, slight noise from starter as if unable to turn engine over. Called tow truck, Seewald's Towing in St. Ignace, MI. Towed to nearest Chevrolet dealer Wheeler Motors Cheboygan, MI.

I was notified that my 2023 Silverado had an open recall (L87 Engine loss of propulsion). I brought the truck to the dealer for the recall on 8/19 with 35,921 miles on the vehicle. The inspection was performed and I was told it passed. When I asked about the extended special coverage they told me they didn't know what I was talking about. Only 4 months and 4,567 miles later, on 12/29, the vehicle shutdown in traffic and was not able to restart. The engine had failed and the starter fuse blew due to the motor being seized. The dealer relaced the engine due to the same recall that the engine had already been inspected and passed the inspection for.

Incident

Jan 8, 2026

was crossing an intersection when the truck suddenly and without warning stopped (engine). Unable to shift the truck into neutral in order to move the truck out of the flow of traffic. This is because the truck has the electronic shifter which requires the truck to be running in order to shift. There is not a manual override. So basically the truck was in the middle of an intersection with cars and trucks weaving around it until the tow truck arrived. But since the truck wasn’t able to be shifter into neutral the tow truck had to maneuver around to the front and “drag the truck onto a flat bed in order to clear the vehicle. Also it turns out that there is a major issue with the fuel pump module on these trucks and the tow truck driver said he has seen this happen a lot and very common. As a result these types of issues are likely to result in a near of fatal accident in the near future.

Sep 1, 2025

While driving and idling, my 2023 Chevrolet Silverado 1500 High Country equipped with the 6.2L v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes P0304 (Cylinder 4 Misfire Detected) and P050D (Cold start Rough Idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted GM's Technical Assistance Center (TAC case #80413912). The service order report states: "Due to unknown noise cannot perform recall. Called TAC 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall." The technician indicated this could be related to a camshaft and lifter issue, which matches the symptoms outlined in GM's active propulsion system recall for 6.2L engines. Suggests GM aware & has not yet confirmed full recall coverage/repairs. This issue presents a significant safety risk because the engine could experience sudden power loss or failure while driving, potentially leading to loss of propulsion or control. These symptoms are identical to those described by GM in their recall documentation concerning valve lifter and camshaft failures. The issue has been reproduced and confirmed by the dealership, and all documentation, diagnostics reports, and service notes are available for inspection upon request. Warning/check-engine lights first appeared in October 2025, and the problem persists. Based on GM's recall acknowledgment of similar failures, I believe this defect should be fully covered under the existing recall, and I am requesting NHTSA's review to ensure manufacturer addresses this safety-related defect promptly and without cost to owners.

Incident

Oct 14, 2025

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.

Date of Incident: [XXX] Approximate Time of Incident: [XXX] EST Location of Incident (City and State): Tallahassee, Florida Street or Highway Name: [XXX], lane between [XXX] & [XXX] Weather Conditions: Clear and dry, approximately 90°F While traveling at approximately 72 MPH in the center lane of [XXX] westbound near Tallahassee, FL, the vehicle suddenly began rapidly decelerating after shuttering, as if the brakes were being applied without driver input. A warning message appeared on the dashboard instructing the driver to restart the engine. At the same time, the steering and brakes became noticeably stiffer, suggesting that the engine had shut down. The driver navigated across high-speed traffic, nearly avoiding being rear-ended by other vehicles, and was able to bring the vehicle to a stop on the shoulder. Multiple attempts to restart the vehicle were unsuccessful. The incident posed a serious safety risk due to the loss of engine power and driving assist features in active interstate traffic. After the incident, the vehicle was towed to Dale Earnhardt Chevrolet (3127 W Tennessee St, Tallahassee, FL 32304), where it is scheduled for inspection on or after Monday, September 30, 2025. The dealership may retain the faulty part(s) and the vehicle is available for further inspection upon request. No prior warning lights or symptoms were noticed before the incident occurred.

The fuel pump went out, left me stranded and was replaced The transmission went out and was replaced. The lifters in the engine were replaced. When will the engine recall be addressed/acted on? The "cure" to install heavier engine oil is a very bad "bandaid"....truly masks the problem. Maybe the Chevy CEO should return her 2024 $25mm bonus to help pay for the repairs.

I was driving on the freeway and smelled gasoline in the cab. I thought nothing of it as I was near a wreck and thought it was from that. About 10 miles down the road I was stopped in traffic and noticed my miles until empty was slowly declining as I was stopped. When I moved forward there was a puddle under my truck. I pulled to the side of the road and fuel was draining from the back of my engine all over the exhaust. I immediately shut the truck off. I cannot believe the gas didn't ignite as those catalytic converters get well over 536°. The truck was towed to the closest Chevrolet dealer over 10 days ago and I have YET to hear anything from them. I bought the truck used from another Chevrolet dealer 3 weeks prior, and it has had the L87 recall.

While driving down the road I let off the accelerator to start applying brakes for a red light I was approaching, then the vehicle shut completely off and down shifted hard. After that it restarted a second later but had no power steering and no brakes. At this point I was approaching the red light with no brakes and power of my vehicle, the other traffic had a green light now and was crossing my lane of travel but I was luckily able to make it through the light in between vehicles without causing any harm to myself or others. After making it through the light I was rolling 10mph still helpless but seen a gas station on my right and rolled into their parking lot and drove towards a curb and used the curb to stop my vehicle. The vehicle had the following warning lights and messages: Lane Change Alert System Off, Brake system failure 62mph top speed, service traction control, service ESC, and trailer brakes disabled service required. I then got the vehicle towed to the dealership while still on and in the running position with all the codes still active. The dealer was able to scan the truck in and see the codes but told me they wouldn’t be able to get to it till the following week so they parked the vehicle and turned it off. When they got to my vehicle the following week they sent me a text and said I quote “Hey ****** its **** from Chevy, I do not have the best news lol he can not get it to act up and there are no current codes he has driven and nothing has happened, as of now there is nothing further he can do”. After receiving that text I called them to just be told they can’t get it to do it again and there is nothing they can do. But I told them I refuse to pick up this vehicle because it had a critical safety issue. This vehicle suffered a catastrophic failure, brakes and steering were lost in an intersection. If not diagnosed properly, this poses a threat to life.
