Filed Oct 29, 2026 · Fuel system · VA

Fuel pump control module failed at under 60k miles. No parts in stock and was told by dealer, no parts anytime soon. This is unacceptable, especially since this is a known problem. A rental car should be provided as expected wait time is now going on two weeks.

While driving down interstate at approx. 55-65mph, vehicle "sputtered" and shut off while driving. Vehicle would crank but not start. After sitting approx. 10 mins, was able to restart and drive approx. one mile or less before "sputter" and vehicle died, followed by another crank no start. No check engine lights came on. Vehicle was in roadway in very dangerous location with blind curve requiring Police to be called in fear of my safety, since vehicle was in roadway, I was afraid for my children's safety as there were in car seats in the vehicle at time of failure. I was also concerned about my safety as well as other motorists safety. I was scared that I was going to get hit by another vehicle since my vehicle died in the roadway in a curve. There was an increased probability of injury or death from the faulty part on this vehicle. Police were on scene to assist with traffic, however no report was made, vehicle was disabled. Vehicle had to be towed to residence. CEL came on after approx 3rd start attempt. Believe issue to be Electronic Fuel Control Module which is common with this vehicle year/make/model. However in contacting the dealer in which I purchased Tahoe, they state that this particular VIN has no open recalls, however it matches description on recall N252516900 Fuel Pump Power Control Module. Vehicle is not yet repaired, it has not been inspected, and faulty part is still on the vehicle, vehicle and part are available for inspection.

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.

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

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.
