INCIDENT 2: Total Electrical / Power System Shutdown Component / System Failed: Electrical / Power Control System (Auto-Stop/Start System) Failure Description: Total loss of electrical power causing the main dashboard and display screen to go completely dark, stalling the vehicle during an autostop event at a traffic light and preventing the engine from restarting. Safety Risk: Sudden total electrical shutdown leaves the vehicle completely dead, unresponsive, and immobilized in active traffic lanes/intersections, creating a high risk of rear-end or multi-vehicle collisions. Dealer / Repair Shop Confirmation: Customer complaint and active fault codes confirmed by dealership service department following standard maintenance schedule. Warning Symptoms: Display screen went blank; failure occurred instantly during autostop/traffic light stop without prior warning. Inspection Availability: Vehicle and affected systems are available for inspection upon request. INCIDENT 3: Fuel Pump Driver Module (FPDM) Failure Component / System Failed: Fuel Pump Driver Module (FPDM - Part #13554821) / Engine Control Module (ECM) Communication Failure Description: Total loss of communication between the ECM and FPDM, causing the engine to abruptly die while idling at a traffic light. Subsequent attempt to restart using push-to-start produced a severe mechanical screeching noise. Safety Risk: Unexpected stall in active traffic leaves the vehicle stranded and unable to restart safely, exposing occupants to collision hazards. Dealer / Repair Shop Confirmation: Confirmed by Service Technician. Diagnostic Code P129F ("ECM lost communication with fuel pump driver module") logged; verified power and ground failures at the module. Replaced FPDM (Part #13554821).

**Mileage at repair:** 76,165 miles **Component:** Fuel Pump Power Control Module While driving my 2021 GMC Yukon XL on [XXX] on a treacherous stretch decending [XXX] the engine unexpectedly stopped running, resulting in a complete loss of propulsion. This occurred on a section of interstate where there was no safe shoulder or suitable location to pull off the roadway. The unexpected failure created an extremely dangerous situation, exposing me and other motorists to the risk of a serious collision. The vehicle was subsequently towed, diagnosed and repaired by Darrell Waltrip Buick GMC in [XXX]. The dealership documented diagnostic trouble code P129F, "Fuel Pump Driver Control Module Fuel Pump Speed Signal Incorrect." The technician verified that the control module had proper electrical power, that there was no pin damage or connector fitment issue, and that the module required replacement. The dealership's written diagnosis specifically acknowledges that a failing fuel pump driver module can cause the engine to shut down. The original factory-installed module was replaced with GM part number 13554821, and the vehicle was subsequently tested and confirmed to operate correctly. The repair was performed at no charge, and GM provided a loaner vehicle while the replacement part was unavailable. I am particularly concerned that General Motors has previously acknowledged this same type of safety hazard under the federal safety agency Safety Recall 21V‑739 (GM N212332040), involving fuel pump power control modules on certain 2021 GM full-size SUVs. That recall identifies unexpected engine stalling and increased crash risk as consequences of module failure. My experience demonstrates the potentially catastrophic consequences of this failure in actual highway operation. I request that the federal safety agency investigate whether a mandatory recall and replacement of these defective components is necessary as the consequences of immediate complete unexpected loss of propulsion.

My 2021 GMC Yukon XL recently suffered a failure of its fuel pump control module. This occurred at just 44,000 miles, mere weeks after my manufacturer warranty expired in June of 2026. This issue goes far beyond a financial inconvenience or a matter of consumer reimbursement; it is a severe, life-threatening safety hazard that GM has failed to permanently resolve. My Experience: Sudden Power Loss While Towing The gravity of this part failure became clear during a recent drive. I configuration-matched this vehicle—a heavy-duty Yukon XL with a 6.2L engine and a 4x4 towing package—specifically for its capacity to safely haul heavy loads. While traveling with a trailer attached, the vehicle experienced a sudden, catastrophic loss of engine power. Without warning, the engine sputtered and died. Had this occurred on a steep incline, a blind curve, or in heavy highway traffic, a catastrophic multi-vehicle collision would have been entirely unavoidable. Critical Safety Hazards and Concerns •Inability to Maintain Speed, Loss of Vital Assist Systems, & Compounded Towing Risks Systemic Failure and Inadequate Remediation What makes this situation entirely unacceptable is that this specific vehicle was already subject to previous GM safety campaigns regarding this exact component (including Safety Recall #N212332040 and subsequent Emission Recall #N252516900). GM is fully aware that their supplier produced defective modules that are prone to premature internal short-circuits. Yet, their remediation strategy has been entirely inadequate. By managing this through piecemeal, phased rollouts and limited VIN inclusion lists, they are leaving dangerous vehicles on the road until the point of failure. Drivers are effectively acting as crash test dummies, waiting for their engines to die in dangerous environments before GM acknowledges that their specific VIN was fitted with the defective supplier part.

March 29th 2026 my 2021 Yukon XL engine stalled while driving at 45mph (No prior warning lamps or messages, restart engine came on dash) causing me to immediately pull over and come to a stop still in traffic, it shifted my vehicle into park, I was in an in an un-safe spot and was stuck in park (conditions not correct for shift on dash) because my vehicle would not allow me to shift to neutral and push it to the side of the road, (could not jump start) Had towed to dealership and mentioned Engine Failure and Fuel pump control module Recalls but according to them it was a starter issue, I asked them to still check the fuel pump control module regardless. Picked up vehicle and a week later April 14th the exact same thing happened vehicle stalled while driving dash said Restart Engine while coasting (No prior warning lamps or messages) forcing me to pull over where it rolled to a stop and locked itself into park leaving me in unsafe conditions again. Had towed back to the same dealership and waiting to hear back from them.

I experienced complete engine failure at around 76000 miles similar to a current engine recall for 2021 to 2024 6.2L V8 engines. However, my engine isn't included in the current recall. I also experienced the fuel pump control module problem requiring replacement. Again there is a recall for 2021 to 2024 6.2L V8 engines and again my engine wasn't included in this recall.

Routine oil change by professional local mechanic. Upon completion we were told that the vehicle would not turnover. The mechanic diagnosed and found that were 2 recalls for our vehicle - one for the fuel pump module and one for the engine. We had our vehicle towed to the local GM dealership. They then replaced the fuel control module. GM tried to manually crank over but engine seized once again. We spoke to the GM Advisor prior to this and were told that our vehicle was not part of the engine recall because our VIN was not listed as part of it even though our vehicle had the same exact issues as described in the engine recall and was for the exact year/make/model of the engine. The dealer quoted us $14,896 to replace the engine. They stated they would submit a Goodwill claim to GMC to help discount the cost to repair/replace the engine. The dealer called back later that day and said GMC would be willing to cover 30% of the cost so our expense would be around $10,000. All this for a vehicle we've only driven for less than a year and a half. The vehicle went in for a routine oil change and has never had any issues prior to this. This happened suddenly without any sort of warning. To make matters worse, our powertrain warranty expired a day or two before this occurred. We are still trying to fight with GMC to cover this engine failure. The car has less than 75,000 miles and is only used for basic personal needs like driving to school and the store so it is shocking that the engine would suddenly fail like this and to make matters, the manufacturer refuses to take responsibility for it and to cover it under the recall even though there has been known widespread issues with this engine.

I was driving with my [XXX] son and my car just stalled out in the middle of the road. I couldn’t start it and we were stuck in the middle of the road. My husband arranged for a tow and the repair shop (safe auto repair Mont Belvieu) told me that this type of thing they have seen a lot of. The fuel pump power control module needed to be repaired and they said when that happens it sometimes shorts out the fuel pump system too. They said they had to repair 4 like this already during the week. My neighbor said the exact same thing happened to her friend gmc at4 a month ago and was also driving and the car just stopped.
