FUEL/PROPULSION SYSTEM 2026-06-22 · NHTSA 11745538

My vehicle, VIN [XXX], is subject to NHTSA Recall 25V455 (Ford Recall 25S75) involving a defective low-pressure fuel pump that may cause engine hesitation, loss of power, or engine stalling. This recall was announced in July 2025 and remains open on the NHTSA VIN lookup as of June 2026. More than eleven months have passed since the recall was announced, and Ford has not provided a repair remedy for my vehicle. I believe this is an unreasonable delay for a safety-related defect. In addition, the recall previously appeared in the FordPass application associated with my vehicle but no longer appears there, even though both the NHTSA and Ford recall website VIN lookup continues to show the recall as open. This discrepancy creates confusion regarding the status of the recall and whether Ford is actively notifying affected owners. I am concerned that my vehicle remains subject to a known safety defect without an available repair and request that NHTSA review Ford’s handling of Recall 25V455, the prolonged delay in providing a remedy, and the inconsistency between Ford’s customer-facing systems and the NHTSA recall database.

I RECENTLY PURCHASED THIS CAR. THE REAR BACK-UP CAMERA WAS IN A FLIP FLOPPED STATE. MEANING, WHAT WAS DISPLAYED ON THE CABIN SCREEN ON THE LEFT, WAS ACTUALLY ON THE RIGHT PLUS THE GUIDING LINES ON THE SCREEN WERE MISSING. I PURCHASED AND INSTALLED A NEW CAMERA FROM FORD. THIS FIXED THE FLIP FLOPPED IMMAGE , BUT, NOT THE MISSING LINES ON THE SCREEN. SECURING THE WIRES I NOTICED THE WIRING HARNESS AT THE BEND AT THE DECK AND LID WAS FULLY EXPOSED TO BEING FRAYED BY THE METAL DECK LID. I DID NOT SEE ANY COPPER WIRE SHOWING.

ENGINE,FUEL/PROPULSION SYSTEM 2025-07-11 · NHTSA 11672874

My 2021 Ford Mustang EcoBoost is currently experiencing an ongoing issue with the EVAP purge valve, a critical emissions component. The vehicle suffers from stuttering, rough idle, and a check engine light, especially immediately after refueling, where the engine has stalled multiple times—posing a serious safety risk during traffic re-entry and acceleration.The purge valve has not been replaced, and the issue remains unresolved. I contacted Ford Customer Relations and three separate Ford dealerships, all of which refused to service the vehicle under warranty, despite the fact that it is still covered under the federal emissions warranty (8 years/80,000 miles) and the powertrain warranty.This refusal contradicts federal warranty guidelines, as the purge valve is clearly part of the evaporative emissions control system. The failure disrupts vapor flow and fuel trim stability, leading to erratic engine behavior and emissions system malfunction.I previously owned another Ford Mustang EcoBoost while living in a different part of the state, and that vehicle experienced the exact same purge valve issue, including stalling after refueling and triggering the check engine light. This recurring failure across multiple vehicles suggests a design flaw or supplier defect that Ford has failed to address.There are hundreds of documented complaints and videos online, including on YouTube and Mustang forums, showing other owners experiencing the same purge valve failure and warranty denial. This suggests a systemic issue that Ford is aware of but continues to ignore.I believe this issue warrants investigation for warranty non-compliance, emissions system reliability, and potential recall consideration due to the safety and environmental risks involved.

At idle the engine idles roughly and rotates randomly at speeds from 300 to 900 RPM.

SUSPENSION 2024-09-26 · NHTSA 11616555

I had to put 3 sets of tires on my car by 50,000 miles. The Ford company told me to go to an alignment specialist because without putting some sort of aftermarket part on my car they can't properly align it and they are tired of fooling with it. I had taken my car for a regular 25,000 mile service, and my tires were so bad that the Ford company would not allow me to leave without rotating the tires. They told me that new tires are soft and not good quality really, they are for selling the car so they are soft rubber. They also told me i had to drive fast because its a muscle car and it would squatt upon going fast making the tires contact the road more even. After getting new, more premium tires and driving another 25,000 miles and the same thing happened at my 50,000 mile service, I started investigating and other year models have this same problem (years 15-23). I am in a situation where I have to put aftermarket parts on my car and potentially void my warranties and pay out of my own pocket. I have had an alignment 4 times and they say it is within specs but at the same time they say I do not have any camber adjustment left to prevent this problem. Ford makes an adjustable cam plate that is 410$ and another 480$ labor plus tax is almost a thousand dollars. Plus another realignment. This is not fair for a new car. I had to research myself and it was most definitely a safety concern. If I hadn't went right on time, I could have had a blow out. My tires have been properly rotated, and not driven in some bad way. It is also an environmental problem because I am throwing away perfectly good tires that are worn thru on the insides

WHEELS 2024-08-22 · NHTSA 11610255

After owning the car for 3 years and putting a little under 50K miles on the vehicle, I have had to change my tires twice now because the inner tread would go bald after 20k miles or so. I had to alignment checked and the dealership said it was within spec. I have kept up with the tire rotations as well and the suspension and shocks are working as well. I believe the problem is that the camber/toe in and toe out specs are too wide that it allows for the tires to wear unevenly.
