I was involved in a car accident on the [redacted] 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.

Significant vibration in the steering wheel when braking between 40-50 mph. It was reported to the dealer and "fixed" but just had it "fixed" for the 4th time. The vibration in the steering wheel is alarming and disconcerting to say the least. No warning lamps or other indications were present any of the times this has been experienced. After each "fix" the timeframe/mileage between occurrences has reduced. The last 3 times, the dealer had the car for over a week to allow them to perform a "comprehensive" fix. If you do a search on vehicle dashboards, this is an issue with many other 2021 mach-e vehicles. Ford continues to pretend like this is limited to my vehicle. …
This is a follow up to ODI 11510437 that was filed via the phone in 2/2023 related to now NHTSA Recall 23V687. The vehicle in question experienced exactly the issue described in the recall notice. Our incident was part of the NHTSA investigation. The vehicle had its high voltage battery junction box replaced in +/- March 2023, but the new box was the same design as the old box that is poorly engineered.

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 [redacted] 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. …
My car has repeatedly had to have rotors replaced due to warping. Between 12,000 and 36,000 miles I've had 7 pairs of rotors replaced. After exceeding 50 mph, when braking I decided violent steering wheel vibrations between 43-35 MPH when braking normally. I have service records and video to back up my claim. Ford is calling this "normal wear and tear" however no other 2021 mach-es vehicles in my geographic area have had this issue, in fact none have had to have rotors replaced at all. This is a serious safety issue, occurring approximately every 3,000 miles. This points to a defective vehicle, Ford refuses to cover the repairs now that the vehicle has passed 36,000 miles despite having a verified service record of 7 rotor replacements. The date below is for the most recent issue, it has been going on for a year and a half. …
I had my MME in to the local Ford dealership for recent work concerning Ford Recall 23S56 (HVBJB). This work was completed along with numerous other software updates needed as indicated by dealership service department. Shortly after getting car back a "1Pedal Drive Fault - Press Brake Pedal To Reduce Speed" warning message was displayed on the instrument panel and the one pedal function quit working. This feature reset it self after the car was parked overnight. Yesterday while driving over many miles this same warning message appeared to happen again and the one pedal feature quit. This happened while vehicle was traveling in an active school zone very near a crosswalk being used by students. This could have been a very bad situation if not quickly going from one pedal braking to two pedal braking which is needed to stop the car.
