Vehicle: 2021 Ford Mustang Mach-E Component: Image Processing Module A (IPMA) / Front Camera / Forward Collision Avoidance System The IPMA and front camera system have failed, disabling Pre-Collision Assist, AEB, forward collision warning, and adaptive cruise control while driving. The vehicle is available for inspection upon request. Warning messages "Front Camera Fault Service Required" and "Pre-Collision Assist Not Available" first appeared August 24, 2022 and have recurred consistently over nearly four years. No accident, physical damage, or obstruction was present at any occurrence. This failure puts safety at risk by silently disabling AEB and forward collision warning during normal driving — systems a driver may depend on in an emergency braking situation with no advance notice they are unavailable. The problem was confirmed by a Ford dealership in February 2026. Their repair order documents: "RAN IPMA SELF TEST AND FOUND DTC SET U3000-49... HARDWARE TEST FAILED... FOUND TSB RELATED REC REPLACE MODULE." The dealer contacted Ford, who authorized 50% off the module replacement only, characterizing it as a "loyal customer discount" rather than a warranty or goodwill repair. I declined to pay for the fix. the federal safety agency Campaign 11028164 (superseding TSB 25-2156) covers this exact failure. Ford's own TSB acknowledges the defect and the dealer confirmed it applies to my vehicle, yet owners are being quoted up to $8,000 for a known safety system failure. I'm requesting the federal safety agency investigate whether this warrants a recall. First occurrence: August 24, 2022 (mileage not recorded) Service visit: February 17-18, 2026 at 80,029 miles Current mileage: 83,988 Attachments: photos of both fault messages, dealer invoice

When in cruise control, any speed, car suddenly accelerates This happens while driving, or sometimes after stopping and then resuming previous set speed. For example I was driving in cruise control at 38 mph, when the car suddenly sped to 50mph. Or when on a highway, driving at 55mph, the car suddenly accelerated to 70mph. Started about 3 weeks ago.

A KNOWN faulty camera problem for 100s of Ford EVs. Starts off as very intermediate warnings until it stops working all together. This problem doesn't allow you to use cruise control and a host of other standard safety features. This should be a recall, I can't imagine someone getting hurt or worse because ford isn't getting ahead of this thing.

Front camera stopped working after a long period of working intermittently (started to happen after passing warranty at 30,000 miles). Without that camera many safety features are disabled, like a front collision warning, lane departure, cruise control with adoptive speed, emergency breaking. The cable and processor issue was confirmed by Ford dealership service.

The car is frequently but intermittently reporting a failure with the front camera: "Front camera fault Service required". When this happens, the adaptive cruise control and other ADAS are disabled, which is a safety hazard while driving the car, especially at highway speeds. This issue began very infrequently in March 2024 and now happens on the majority of trips when driving the vehicle. I took the car to a Ford service center for repair. They did a software update on the car and told me that they were sure that the update would fix the issue. The front camera fault re-occurred within a week after having the software update done.

Received intermittent warnings that the front collision warning system, cruise control and front camera were not working. The problem I think began after having my roof/windshield removed/reglued under recall. It was intermittent and I could not tell if software updates were resolving the problem, but then the problem became permanent at which time my car was out of warranty. Which does not seem fair since the problem began during the warranty period,. likely as a result of the windshield recall.

Received a front camera fault warning in the car. The fault disables the safety feature of pre-collision-collision assist. Had an independent service center check it out, they let me know there is a TSB from ford. Waiting for the a scheduled appointment.
