2021 Ford Mustang Mach E brakes problems

Filed Oct 3, 2026 · Brakes, Steering · NC · crash

I was involved in a car accident on the XXX I was in the turn lane and a second vehicle hit my driver side, spun me around, and I ended up facing the opposite direction. What occurred next is my safety complaint. The vehicle continued to travel forward and, in fact, accelerated and I was unable to turn or stop in spite of hitting the brake. It caused me to hit a third vehicle and I stopped short of a gas line. There was a recall on this vehicle 22S29. The issue was a functional safety monitor software fault which potentially caused unintended acceleration, unintended deceleration, or unexpected movement I purchased the car in 2023. The recall was dated May of 2022 and was noted on the market valuation report / supplemental information. I was not aware of this recall and I do not believe the issue had been corrected prior to purchase in spite of being told that all recalls had been addressed prior to my purchase. Luckily, nobody was severely injured. I sustained chest wall contusion from the airbag, possibly rib fracture(s) and sternal fracture. My grandson who was [XXX] old was in the backseat and he was not injured luckily but was very traumatized. There were no warning signs. There was a police report but no ticket. The car was totaled so it is not in my possession at this time. The auto dealer that had performed several recall issues for me after my purchase did not have any record that this particular recall had been addressed. I have filed a complaint with Ford as well.

If the pads need to be replaced 4 time in 42,000 mile on a vehicle with regenerative braking there is a obvious issue. I feel this is an on going issue that was never corrected .

I bought a certified pre-owned 2021 Ford Mustang Mach-E GT. The brakes always kind of made a grinding but i figured it was the brake dust on the rotor since the car had sat on the lot for a while. I took the car into Maplecrest Ford in Union, NJ for this issue and they replaced the rear brakes under warranty. Shortly after that I felt a vibrating on the highway, I figured it could be the brakes bedding in. After that it became more persistent and I took the car to the dealer on [XXX] and they told me the front brakes had to be replaced. The car was purchased with 16,500 miles, went to the dealer at 17,000 miles and has 17,500 miles right now. It is impossible to believe that brakes on an EV (where most braking is regenerative) need to be replaced down to the caliper. I read Ford TSB 22-2023: Vibration/Pulsation From Brakes - Brake Pad Material Stuck To Rotor - Built On Or Before 06-Jan-2022 that describes this very issue. Ford essentially notes that pad material will become dislodged and get attached to the rotor. That they're not replacing this under warranty and that they haven't issued a recall for brake pads they've already redesigned because they can break apart is extremely dangerous. There's notes of this happening to cars on Mach-e message boards and Ford is aware because they've issued a TSB: [XXX] (for example). I would strongly encourage the federal safety agency to implore a recall before someone gets hurt. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
