P129F fault code: what 67 owners reported

vehicle has 19000 miles on it. While driving, the engine died in traffic. I was sent a code from on-star of P129F. I had the suv towed by AAA to the nearest Chevy dealer and had to get a hotel. After researching, I discovered that this is a common problem with a multitude of GM vehicles whereas the control module for the fuel pump has a known failure issue. The module is an FPDCM module. The issue is so frequent that GM has a service bulletin 24-NA-139 and yet there is no recall. My suv has been serviced by Chevy dealerships over 4 times since purchasing new and this module should have been replaced before I was put in a potentially dangerous position. A recall needs to be issued…

I was at a stop light. Let my foot off brake vehicle revved up and I launched into a vehicle in front of me. Check engine light was on before. Blinking, esc fault , forward collision detection was not working, traction control service light. Throttle body control issue detected code P0205. Valve timing issues detected codes p0353 p0355 p129f p0300. The wire above my shock bolt is completely cut into. GM did an investigation and said no issues were detected at all. There is a TSB for the wire chafing

The truck shut off and would just crank. It threw the code P129F. And wouldn’t start up until after 15 minutes.

My 2022 GMC Terrain lost power and stalled while I was driving, creating a safety risk because I could no longer maintain speed in traffic. The incident involved a police response and a safety-related tow costing $250. On XXX, OnStar recorded diagnostic trouble code P129F. Tire Choice subsequently replaced the fuel pump control component, identified in my records as GM part number 13554821, at a repair cost of $493.25. I have supporting diagnostic, repair, towing, and police documentation, along with evidence of the removed part. GM’s later vehicle history printout showed zero open field actions for my VIN [XXX]. I am concerned that this failure may be related to the fuel pump power control…

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…

Pulled out in 4 lane traffic. Got almost to 55mph. Vehicle lost all power, slowed down and auto shifted to neutral, vehicle stopped and went to park. Vehicle would not start back nor transition to Neutral to remove from highways. 2021 suburban with just 35,000miles. Shut down a lane on a 55mph highway. Code P129F

Vehicle engine stalled while driving in school parking lot. Safety concern as car when from “R” to “N” while backing up (2x). Engine would not turn on afterwards. Vehicle code P129F showed trouble with fuel pump power flow control module.

While exiting the highway from 70MPH my truck quit running on the exit ramp as I approached the end of the ramp. The truck would not restart and blocked traffic until I was able to get a tow truck. After the truck was towed back to my home I was able to scan the truck and found P129F code reporting (Fuel Pump Driver Control Module Fuel Pump Speed Signal Incorrect) (see attached report). Only after purchasing a Fuel Pump Driver Control Module from the dealer (P/N) 13565641 (replacement for the original 13531875 P/N) and installing it would the truck start. This was a real safety concern as other driver were also exiting the highway at speed while my truck was blocking a lane. The fuel pump…

While driving northbound on I2 at approximately 70mph I experienced a sudden loss of engine power. Vehicle would not accelerate and engine ultimately powered off. I was able to move across three lanes of traffic and pull over on the side of the highway. I attempted to restart the vehicle but was unsuccessful and after about 10 minutes the engine managed to start. The ‘check engine’ light was on after the incident and upon arriving back home I ran a code scan that resulted in code P129F indicates a problem with the fuel pump control module. There is recall #N252516900 dated 9/11/2025 which covers this issue for 2021 models only. This occurred on a 2023 model.

To whom it may concern; my son's fiancé was driving on the highway and the vehicle had a sudden loss of power. Afterward, it turned off and would not re-start. After towing the vehicle to a repair facility (out of warranty by mileage, 45K) were advised they retrieved DTC P023F and advised the fuel pump control module failed. I did some checking and found that GM is aware of the issue and has released T.S.B. #PIP5964C, which states "CRANK NO START, STALLING, LOSS OF POWER, FUEL GAUGE INOPERATIVE/ERRATIC, MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATED P023F P129F". Fortunately nothing happened, she is young and smart and was able to handle the situation without incident. However, I shutter to…
