2021 FORD MUSTANG MACH E Complaints

After transitioning from i35 south, to Highway 183 towards Austin-Bergstrom International Airport, the auto-pilot (Ford Blue Cruse) fails, the speedometer fails, the battery level indicator fails, the instrument cluster fails, cruse control picks a random speed and struggles to keep it, lane keep assist is erratic at best. This occurs every time, and in both directions, I take my vehicle on that highway. I took a video of it this last time, and offered it to Ford. They recommended I file this report with this agency.

The contact owns a 2021 Ford Mustang Mach-E. The contact received notification of NHTSA Campaign Number: 23V687000 (Electrical System) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

While driving the cluster goes black. It does not show speed. It goes black for about 5 seconds and reboots. this happens about every 15 minutes while driving.

The contact owns a 2021 Ford Mustang March E. The contact stated while driving at various speeds the message "Power Train Failure, Unsafe to Drive" was displayed and the speed was reduced to 55 MPH. The vehicle was taken to the local dealer who diagnosed that the high-voltage battery junction box and PCM were faulty and needed to be replaced. The vehicle was not yet repaired. The contact stated that the vehicle was previously serviced for the same failure on two separate occasions. The manufacturer was notified of the failure, but no assistance was provided. The contact was informed that the VIN was not included in NHTSA Campaign Number: 23V687000 (Electrical System). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 12,000.

Forward collision warning has been coming on over 5 times now along with cruise control not working

Front camera fault and pre-collision assist not available warnings. Car is unable to use cruise control or lane departure assist or warning.

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.

While driving with my 1 year old in the car, there was a car in front of us turning so we slowed down. After it made its turn, the driver (my dad) accelerated to continue on our drive. During the acceleration, we heard a loud noise and the car stopped in the middle of a busy road. The notification came on the dash stating to safely stop because the battery failed. We did not even have a chance to pull over before the car completely stopped and would not move. We were stuck in the middle of a busy road. I called Ford assistance and they sent a tow truck. I had to wait in the freezing weather with my one year old baby for my father to uber home and get his car. There was no other warning prior to the failure. The car is now at Ford where they say they are getting a new battery to replace the failed one. Now i am without a car but more importantly i feared for mine and my childs safety when the car completely stopped in the middle of the road. The vehicle has not been inspected by anyone other than the dealer.

Vehicle in Adaptive cruise will unintentionally accelerate when a motorcycle is lane splitting to the right of the vehicle, causing the vehicle to accelerate towards a slowing or stopped vehicle. This puts me and other motorists at risk of a crash.

There is a software problem which was introduced in a previous OTA which causes drive modes to change. These drive modes are Whisper, Engage, and Unbridle. Each has their own acceleration/throttle response characteristics, as well as steering and suspension feel. You also have the ability to enable one-pedal drive in the drive mode menu. The software bug will randomly throw an error on the main screen that says "Drive Mode Not Available" change your drive mode from Whisper or Unbridle to Engage, affecting the throttle response that can occasionally lead to unintended acceleration. On occasion, it can also lead to disengaging of the one-pedal drive mode at the same time, which can cause the vehicle to not slow down when the foot is lifted off the accelerator. If the driver is unaware that 1PD has become disengaged unintentionally (which cannot be re-engaged without power-cycling the vehicle), it could lead to a crash as the driver is not expecting to use the brake pedal. In a moment's notice situation, it could be deadly. The vehicle has not been inspected, however, this problem has been reported by many other Mustang Mach-E owners. I will link my forum post at the end of this report which has other claims of this fault. The vehicle is available for inspection upon request. It cannot be easily reproduced as it is entirely random. Yesterday (11/8/2023 @ 1:40 EST), I was pulling into a parking spot with concrete posts around it. This time, it happened as I was turning into the spot. I was in Whisper mode this time. I noticed the car SPED UP a bit as I was letting my foot off the accelerator, and I had to slam on the brakes. Sure enough, "Drive Mode Not Available" was up on the screen. I was about 1 inch away from this concrete post. If my reaction time was just a bit slower in hitting the brakes, the vehicle would have crashed itself, relatively outside of my control. https://www.macheforum.com/site/threads/huge-safety-issue-1pd-drive-mode-not-available.31712/
