Ford had a recall on the brakes. The brakes were services 3 times in relational to this issue. Now again the front end shutters when braking especially at highway speed. The dealer says the pads need to be replaced and the rotors resurfaced .This is the 4th time in 42,000 miles. they will not warranty this on going issue. 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 NHTSA 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)

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. Ford clearly doesn’t understand how to fix it, as the same fix has been recommended every time to the same result. I can’t upload the videos but happy to send for additional support of my the defective vehicle assertion, it helps to show how much of a safety issue this is.

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.

After getting the HVBJB recall, I have had 1 pedal drive mode turn off unexpectedly about once a day. Since I expect my car to start breaking when I am off the accelerator pedal, when 1 pedal drive disables the car will move faster than expected if I am off the accelerator pedal. This could result in running a stop sign or hitting another car due to this unexpected lack of breaking. I do get a warning (while driving) on the dash screen that 1 pedal drive had a fault and was disabled. I have not taken my car into a dealer.

One pedal drive system failure. Had the 22B50 charge port recall done on the 18th of April 24. After leaving the dealer upon approach to a light one mile away, one pedal disengaged during de-acceleration for the light. Warning did come up near the same time. It felt like vehicle was accelerating, but just loss regen. It has since happened daily. sometimes multiple times. Restart the car and it works normal. The recall was to reprogram the BCCM according to the dealer.

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. Fortunately no cars were ahead of me and I was able to quickly slow the vehicle by braking, but I'm alarmed as to what would have happened had this been in traffic.

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. Notices sent out in Fall of 2023 indicating that there was a recall were not sent to us for this vehicle. Similarly, the notice sent in April 2024 informing Mach E owners to schedule appointments at their dealer was not sent to us for this vehicle. Upon contacting Ford, they indicated that this vehicle is not part of this recall. After insisting on speaking to a supervisor, he claimed that it was now a part of the recall but refused to provide me any written acknowledgment of this. When pressed further he then said that our vehicle was not part of the recall because the part was already replaced. When I explained that the part replace was the same defective part he told me to call the dealership or NHTSA because he would do nothing further. He went on to say that there was nothing further he would or could do, nor would it transfer me to anybody at Ford that could address our unique circumstances. Upon calling NHTSA they advised, (amongst other things), that we file a complaint via this portal.

heavy vibration and pulsation from brakes when stopping from 50 mph. Steering wheel jumped out of my hands on a panic stop one time. I would say this is a safety issue that apparently Ford already knows about with service bulletin #22-2023. Ford refuses to make the repair under warranty because they say it's a wear and tear issue-even thought they admit to faulty brake pads. The problem was confirmed by the dealership and they wanted $1300 to fix their defective brake pads.

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. While they have covered the reports thus far, having a vehicle with (now) 30,000 miles on it and multiple issues with the braking system (and it appears to be a systemic issue) is unsafe and causes significant lack of faith in my ability to brake safely. While I was assured by Ford that the brakes work fine and it wasn't unsafe, a jarring vibration in the steering wheel when decelerating in a specific speed range is not safe. The information in the "additional" details is for the latest (now 5th time) this is being addressed.

I was driving on the highway (12) in Mandeville, Louisiana and the car (a 2021 all electric Mustang Mach E with only 13k miles) flashed a 'Stop care safely now' sign and then proceeded to power down within 3 seconds of the message. I exited (luckily I was at my exit) and felt the car lose power on the exit ramp. Three signals came up (battery - yet I was at 100% - then a turtle mode and not sure what the third symbol was) and then the car locked up - went into park, would not move or allow me to put into neutral to pull off a very busy highway ramp. I was forced to a dead stop on the ramp (very dangerous). I put on my hazard lights but cars still pilled up all around me, beeping etc. at high rates of speed. I called 911 and the police came out (took about 10 minutes during which time I had to direct traffic around me - again very dangerous) and asked that I move the car but the car would not move or even go into neutral. A DOTD tow truck towed me to a nearby Winn Dixie and then the roadside assistance towed to the Ford Dealer. The Ford Pass app send me the message attached below that said it was forcing a software update and the car would not be able to be used during this update - while the car was in drive and while I was driving it down a four lane highway! Very unsafe considering the car was connected to WIFI at home and that update could have been done at any time - not while driving. There was no notice prior to this that a software update was needed and we have it set for updates to happen at 1 am. The car relies upon software (not firmware) to run and if that fails, the car just locks up. This car should be recalled. I am lucky no one was injured including me trying to direct traffic on a busy high speed highway ramp. The policeman was very frustrated and made me get out of the car. Then the DOTD driver confirmed it would not budge. Thank God this didn't happen while I was in the middle of a 4 lane highway. It would have been like stopping on a train track.

All of the advanced safety features have stopped working in my Mach E The curse control does not work either the adaptive or the standard. The pre-collision system is not working, lane assit is not working. The absence of these working systems is a danger. Ford knows about this software problem with the software, however they refuse to fix the problem at there expense. The Mach E was designed from the ground up as software driven, the manufacture should be responsible to ensure that the software is up to date.

Stuck Disk Brake: The left rear disc brake was stuck. After releasing the parking brake the car would not move. After two attempts to reverse the brake released. There is a loud thumping sound from the rear wheel. While braking there is a violent vibration coming from the left rear wheel. The car is parked now and will be towed to a Ford Dealer. In the on-line Ford Mach-E forum there are other complaints about brakes being stuck with similar description as above. My car was last driven in wet weather and then parked in a garage. Temperatures at the time were cold but not freezing. The temperature at the time of incident was about 50 degrees Fahrenheit. This seems to be a safety issue.

* On October 16th, 2022, at about 7:00 pm, I was driving my 2021 Ford Mach-E GT when we began to change lanes (we were in the left lane heading East) as the vehicle in front of us slowed down to make a left-hand turn. There was a car behind us and two vehicles in the right lane (two-lane road in each direction) that were a few car lengths behind us as we began to change into that lane. When I turned on my signal and turned the steering wheel, I pressed the gas pedal to accelerate to get around the car in front of me to keep my distance from the vehicles in the lane I was transitioning into. Unfortunately, when I pressed the gas pedal, we experienced complete vehicle failure. I had no steering, brakes, or acceleration. Within a short time (30-45 minutes), we had no power as the lights on the vehicle, and all electrically powered devices and components were entirely out. This made it very difficult to tow the car as it is all-wheel drive, and we could not put it in Neutral to pull the vehicle. As this happened, five cars were in the area, and several had to swerve and fly off the road onto the dirt shoulder. We barely missed the car in front of us, and the car behind us had to lock up its breaks not to hit us. Our car gradually slowed down and cost off the road about 50 yards or so after losing power, as it was very difficult to get the vehicle to steer; it took everything I had to turn the wheel to get it off the road. We put on the emergency blinkers, but the vehicle lights flashed erratically inside and outside the car. We had over a dozen warnings flash on our dashboard about vehicle failure. The speakers in the car were making a thumping sound on their own as the car was flashing headlights, brake lights, and flashers on their own and very sporadically. It was like a disco club in the car as all the lights were flashing on and of at a rapid rate. The other cars stoppe and were very angry at us as the screamed at us that we almost caused an accident.
