My vehicle, 2023 Tahoe, previously had the GM Recall 25V-274 / N252494001 remedy performed (0W-40 oil swap) in October of 2025. Despite completing the manufacturer's official recall remedy, the engine suffered a sudden, dangerous loss of motive power at highway speeds when I was making an out of state move and traveling alone; it was terrifying. I had to have it towed to the nearest dealership and that is where it is now as I had to leave since I was in the middle of moving. I need a new engine. I have no idea how I will get my Tahoe to my new residence or when. The dealership was not open on Sundays so I had to find a place to stay after leaving my Tahoe full of my items and my bike. I was so afraid it would be broken into. I had an oil pressure warning right before the engine completely stalled. And, I was accelerating up an incline and it felt like my Tahoe couldn't get enough power to make the incline. My Tahoe only has 35,047 miles, and threw the Diagnostic Trouble Code P0016 through my ONSTAR app as well as with the tech at the dealership. And, I am having a lot of trouble with GM corporate with rental cars. I had to pay out of pocket in order to get back on the road with my belongings as I start a new job this week at my new home. I had to leave some belongings and my bike with my Tahoe at the dealership.
NHTSA complaint #11756494 — an unverified report by a vehicle owner.
Fuel Pump Power Control Module failed. GM Part Number: 13554821 My vehicle immediately became immobilized in a lane of traffic. The engine would crank but not start. It appeared that no fuel was pumped. This was confirmed with engine code P149F. GM diagnostic code P129F indicates a Fuel Pump Driver Control Module (FPDCM) fuel pump speed signal fault… My vehicle with 51,000 miles was serviced on 5/6/2026 for PA inspections, oil change and transmission flush. The VIN has no open recalls. GM has recognized the failure rate of the Fuel Pump Power Control Module, GM Part Number: 13554821 on many 2021vehicles and issued 2 recalls: 21V739000 issued September 23, 2021 And N252516900 issued September 11, 2025 Recall N252516900 was issued as a “phased launch” and yet (per GM) the Reason For This Recall: Certain vehicles may have a condition which can cause the fuel pump power control module to fail. If this were to occur, fuel flow to the engine could be interrupted. And Consequence Summary: An engine stall increases the risk of a crash. The vehicle instantly can become immobilized regardless of its location, in the middle of an intersection or in a lane of traffic. Without the engine running, the Tahoe cannot be shifted out of Park and cannot be pulled, pushed or dragged without causing damage. It must be properly loaded on a flatbed and be hauled from the failure site. GM “phased launched” the September 2025 recall to handle parts shortage. GM realizes how CRITICAL this recall is because a vehicle can become totally immobilized instantly. The dealership says my VIN shows no open recalls and are resistant to making a request for authorization to apply this recall. I think the failure of the Fuel Pump Power Control Module needs to be escalated until recall indicates ALL vehicles involved. I am glad I wasn’t entering a busy intersection when my vehicle became fully immobilized. As it was, vehicles were unable to go around for the 45 minutes I waited for a tow truck.

When GM announced the recall involving the potential for catastrophic engine failure, I immediately contacted Bridgewater Chevrolet in NJ to schedule the required recall inspection. I was told the dealership could not perform the inspection because it had not yet received the required 'diagnostic tool' from GM. Once they received the equipment, they contacted me and on Oct 1, 2025, they completed the required recall inspection and informed me that my Tahoe had passed the recall inspection and that the vehicle was safe to continue driving. On XXX while driving over the Driscoll Bridge on the [XXX] with my daughter and our dog, the engine catastrophically failed without warning as I began to exit on exit [XXX] to [XXX] into heavy traffic. With no warning, the vehicle flashed that it was in neutral and then suddenly lost all power and stopped completely in a traffic lane, creating an extremely dangerous situation. After a few mins, I was able to get it started briefly, enough to coast along to a spot a few hundred feet away where there was a shoulder. From there the wheels locked and it would not move at all and windows would not open. It had to be dragged completely inoperable with locked wheels onto a flatbed three separate times. It was first dragged and flat bedded off the Parkway to a place we felt unsafe so we stayed locked in the car in July heat with no windows down, then to my mechanic and then to the dealership. I am unsure of the damage that may have caused. The dealership received the vehicle on XXX and within a day told me that it was indeed what my mechanic and they suspected - the catastrophic failure recall they had inspected and passed the vehicle for. As of today, XXX, I was told they just received an engine and can start a full replacement this week. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11755999 — an unverified report by a vehicle owner.
I was driving on the highway and my car lost power and then had to shut down. I am now getting error code P129F. which is a known recall for the fuel pump control module. When I put in my VIN, it doesn’t show my car part of it, but it is a 2021 Tahoe experiencing the exact same issue and getting the same error code that is part of the recall. I also read that it is part of the federal emissions warranty, which is eight year 80,000 miles. My car has 59,000 miles on it and I verify that it’s still under warranty from that standpoint. I want to take it into the dealership on Monday, but I need to know what my options are to get it repaired for free under this recall since currently my car is not coming up via this VIN under this recall
NHTSA complaint #11755652 — an unverified report by a vehicle owner.
The engine in my 2021 Chevrolet Tahoe High Country equipped with the 6.2L V8 (L87) experienced a catastrophic failure. While driving, the vehicle suddenly lost power, displayed a “Service ESC” warning, illuminated the check engine light, and unexpectedly shifted into Neutral. After stopping the vehicle, it would not restart. The dashboard would illuminate, but the engine would only produce a faint clicking sound and would not crank. The vehicle was towed to a Chevrolet dealership, where it remains available for inspection. How was your safety or the safety of others put at risk? This failure occurred while I was driving, causing an unexpected loss of power and propulsion. The vehicle became disabled without warning, creating a significant risk of being struck by surrounding traffic. Losing the ability to accelerate or safely maneuver a full-size SUV in traffic placed both me and other motorists at risk of a serious crash. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The vehicle was towed to an authorized Chevrolet dealership, Crews Chevrolet. The dealership confirmed that the engine had catastrophically failed and advised that it qualified for replacement under General Motors’ special coverage program for the 6.2L L87 engine. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle has been inspected by an authorized Chevrolet dealership. General Motors has authorized replacement of the engine under its special coverage program. No police report was filed because there was no collision.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving on several occasions at various speeds, the check engine warning light illuminated, and the engine started running rough. The vehicle was taken to a dealer where it was diagnosed with three inoperable fuel injectors. The contact was informed that the fuel injectors needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately four years later. The contact stated that while driving on several occasions at various speeds, the engine was running rough with the check engine warning light illuminated. The vehicle was taken to the same dealer where it was diagnosed, and it was determined that fuel injector #5 needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately 2 and a half years later. The vehicle was then taken to an independent mechanic, where DTC: P04320 was retrieved, and the fuel injector on bank one that was previously replaced was not running at the right efficiency, and the catalyst for bank one was not operating as needed. The vehicle was not repaired. The vehicle was taken to the same dealer where it was diagnosed, and it was determined that the fuel injector that was previously needed to be replaced was at 20% and did not need to be replaced. The vehicle was not repaired, but the failure reoccurred approximately 7 months later. The vehicle was taken to the same dealer, where it was diagnosed, and it was determined that all four injectors on bank one were inoperable and needed to be replaced. The vehicle was repaired, but the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 34,141.

I was a victim to the L87 Engine Loss of Propulsion recall. On June 19, 2025, my engine was replaced as it failed all test. After getting a new engine, I have had 5 engine misfires and the dealership blamed it on faulty gas. Now my 2023 Chevrolet Tahoe that I trust to drive my two toddlers around, is at the dealership for a flashing engine light. Even after the engine was initially “remedied”, the new engine continues to fail and I have lost trust in having a safe and reliable vehicle.
NHTSA complaint #11750154 — an unverified report by a vehicle owner.
DATE: 06/17/2026 The engine shuts off without warning while I am driving, recurring roughly every 10 miles. When it stalls, the dashboard and electrical accessories stay on, but the vehicle loses motive power, along with power steering assist and power brake assist, which is extremely dangerous at road speed and in traffic. This began immediately after dealer service completed on 6/18/2026. During that visit the dealer performed two safety recalls (N252494000, the "L87 Engine Loss of Propulsion" PicoScope inspection with oil change; and N252510321, ECM software reprogramming) and a valve lifter replacement that required removing both cylinder heads. The vehicle was running and fully drivable when I dropped it off, and was returned stalling repeatedly while driving. It never did this before the service. At first the engine would not restart after stalling. The dealer replaced the starter; it now restarts but continues to stall every ~10 miles. A dealer diagnostic scan recorded numerous "Lost Communication" codes across nearly all control modules, plus control-module input-power codes showing low voltage and power-circuit correlation faults (e.g., U3505, U3018, U3007) and an active loss-of-communication code for the power steering module — consistent with an intermittent loss of electrical power or ground affecting engine control. The engine passed the recall's connecting-rod/crankshaft (PicoScope) inspection, so this is not the recalled bearing failure mode. The vehicle is currently at the dealership and is undrivable. The dealer has ordered a new engine and apparently also a new radiator for reasons unknown. No crash or injury has occurred to date, but the vehicle lost power while on the freeway at speed multiple times. A GM customer assistance case is open. Repair orders and the diagnostic scan are available on request.

Tahoe failed mid driving in a public roadway, computer system said press to restart and car made a whirling noise. I was unable to restart or put into neutral to move. This was a safety concern due to it happening mid driving, and I had my two young children with me.
NHTSA complaint #11748053 — an unverified report by a vehicle owner.
The engine's Dynamic Fuel Management (DFM) lifter failed and damaged the camshaft at around 70,700 miles. The broken components are available for inspection upon request. This failure put occupants at risk because the vehicle suddenly lost power, began shaking violently, and could not accelerate safely in traffic. This unexpected loss of propulsion created an immediate collision hazard. The problem was officially diagnosed and confirmed by a repair service center. It has not been inspected by police or insurance representatives. There were no advance warning signs. At the exact moment of the failure, the check engine light started flashing, the car began shaking heavily, and the engine made a loud knocking sound.

Fuel pump relay module failed, we had the vehicle towed to a mechanic and payed for the repair, a week later we received mail from GM saying the fuel pump relay module was faulty in our model, that we could take it to a dealership and have it repaired, or if we had already had it repaired we would be reimbursed, the dealership refused to reimburse us, and directed us to GM customer service, we sent the required documents in October of last year, received a call from a GM representative to let us know they were reviewing our case about 3 days after sending the information in, we haven’t heard from them since.

While driving, the engine started to shutter and run rough. Pulled over to check and see if everything was ok. When restarting engine it developed a ticking noise which got worse and worse. We then made an appointment at a transmission specialist to get it serviced. While driving there the engine started experiencing engine failure with loss of power and loud ticking noise. Diagnostic from trans shop showed issues with engine and cylinder 4 misfire detected. Yes, the vehicle can be inspected upon request. Safety was put at risk while driving when engine started to fail. Had to pull over and have towed. Independent service center has confirmed issues. Report in attachments. No warning lamps or messages appeared prior to failure issues. The issues first started on March 18th 2026. SUV has been un drivable since. We have been unable to find a repair shop who is willing to do the repairs needed. The vehicle really needs a whole new engine.
