What owners say about the vehicle speed control
Verbatim from NHTSA complaints, newest first
“The contact owns a 2021 Ford Mustang Mach-E. While the contact's daughter was driving at an undisclosed speed, the vehicle independently accelerated. The brake pedal was depressed; however, the vehicle failed to stop as intended. No warning lights were illuminated. The contact stated that the failure occurred while the vehicle was being parked in the residence driveway. The vehicle crashed into the right side of the residence before coming to a stop. The air bags did not deploy. The contact stated that the right side of the garage was damaged. No injuries were sustained. The contact stated that the failure was a known failure with the vehicle. The contact stated that an unknown recall with a similar failure was completed in 2022. The vehicle was towed to a local tow yard. The vehicle was deemed a total loss by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.”
“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…”
“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.”
“Was driving and suddenly all errors started popping up Hill start assist warning 1 pedal driving unavailable Pre collision assist not available Antilock brake fault, etc Lost braking power, steering got stiff, accelerated suddenly.”
“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.”
