Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“As I was driving down the road (in motion / city street) at 30 miles per hour in my brand new (4 week old / 2200 miles) all electric Ford mach e, the display flashed multiple warning lights that came too quickly to decipher, and then the car went dead. I was able to pull off the road and come to a stop. At this point the car was completely dead. Even the hazard lights wouldn't work which made the situation dangerous since the cars behind me could not tell that there was a problem.”

NHTSA complaint #11415152, filed 2021-05, 2,200 miles

“Unintended acceleration from a stop when pushing accelerator. Has happened 2 times in the last 2 days. I touched the throttle from a stop 2 time and it took off like I put the accelerator to full throttle (which I didn’t). Very dangerous situation in parking lots or around pedestrians. I have scheduled an apt with my local dealer.”

NHTSA complaint #11511215, filed 2023-03

“When stopped at a stoplight, in unbridled mode with one pedal driving engaged, the car surged forward on it's own. The surge forward caused my vehicle to rear-end another vehicle. I would assume the failure was the one pedal driving system and it is available for inspection. The problem has not been reproduced or inspected yet, but we have an appointment for a Ford dealer to evaluate the car. The only warning was the pre collision warning which did go off.”

NHTSA complaint #11610754, filed 2024-08

“Having completed the high voltage junction box recall with the Mach-E a week or so before, I was braking in order to complete a left-turn in one-pedal drive mode (therefore lifting my foot off the accelerator causing the vehicle to slow down). I received a notification as I did so that one pedal drive mode had a fault and was deactivated (this appeared on the screen by the steering wheel). This caused the car to lurch forwards, as it shifted from OPD to standard drive mode. …”

NHTSA complaint #11585092, filed 2024-04

“I have complained several times with Ford Dealers to fix the issues involving my vehicle accelerating on its own. The vehicle within a week will accelerate on its own 4-6 times when exiting a parking spot or my driveway.”
