Cadillac XT4 fuel pump problems

Filed Jul 24, 2026 · Fuel system · FL

I was driving down the road and my vehicle lost power and quit running. Luckily I was in the lane closest to the shoulder and was able to pull over on the shoulder and was not able to restart my vehicle, but had this happened in another location this could have been a huge safety problem for me and others with the vehicle completely losing power while driving in the middle of traffic on highway 27. The vehicle is still under warranty and has 10k miles. I am the only owner of the vehicle and it has only been serviced at the Cadillac dealer. The Cadillac dealer was able to inspect my vehicle and determined that the fuel pump module went bad and replaced it and advised that this has happened to other Cadillac, GMC, and Chevrolet suvs.

Vehicle died leaving the doctor's office due to faulty fuel pump driver control module. Upon research found that this has been an ongoing issue for several years affecting many GM vehicles. Vehicle can stall at any time in traffic causing serious injury or death. Apparently GM does not have a fix for this problem & the company's solution is to replace the faulty module with modules that have the same defects. Also, when affected vehicles stall in traffic, the parking brakes set & there is no way to even put the vehicles in neutral so that they can safely be moved out of the roadway. This increases the chances of causing a serious accident if one was not caused by the initial breakdown. GM should not be allowed to sale these vehicles with faulty parts putting countless lives in danger.

I was getting out of a parking lot with my 3 kids and the car shut off right in the middle of the entrance/exit of the lot blocking anyone from coming in or out. The car would not go into neutral to move it, making it unsafe for my family and everyone around us. We tried to charge the battery but that did nothing. We called tow truck then where told we need a special tow truck since the car could not be put into neutral. We waited hours for a tow truck, when we finally go there, the car's emergency breaks keep coming on and would not turn off. We ended up removing the battery. I was told that it was the Module fuel Pump shorted out, it was a common issue. I asked how we could put the car in neutral and he stated that there is no way to put the car in neutral when this happens, which is a safety issue. This should be a recall. I have the app that is supposed to alert me if there are any issues, nothing showed until after the call shut off, even then all it said was that the battery was low followed by an issue with the fuel management system.

there is a recall on the 2021 cadillac xt4, fuel pump control module, N252516900, but my vin is not included. My vehicle seems to be having the same issue. The dealer has been unable to diagnose as it has been happening very sporadic and I don't drive often. Issue first occurred, vehicle would not start in June 2025, clicking noise, happened few times in December and now seems to occur more frequent. car will initially start but will stall and fail to start. vehicle usually starts and engine light stays on, but then engine light will go off within hours. Dealer indicated no error codes were stored. had onstar run a diagnostic today when I had issues and identified a fuel management system issue. In researching I located the recall notice and ran my vin.

Car suddenly stopped while driving and would not start and stalled. Tried to restart multiple times with failed to restart. Car cranked but did not start after multiple attempts. There were no warning signs or indication before stall. Luckily, incident happened in parking lot way out from it. Traffic behind had to steer to other lane to maneuver. Stalling on public road or freeway could’ve been a safety concern for occupants and others. Dealer diagnosed the issue as faulty fuel pump driver module and replaced the part. Issued was fixed under vehicle manufacturer warranty.
