2021 FORD MUSTANG MACH E Steering Problems

The car steering oscillated right and left similar to a 2022 recall description.

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...

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...

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.

I am filing this complaint regarding the potential failure of the High Voltage Battery Junction Box. There have been many failures reported on the forums some experiencing multiple failures. Ford provided a software update that supposedly predicts an impending failure reducing available propulsion power. I do not feel comfortable driving a vehicle with a ticking time bomb. Losing propulsion power while driving at highway speeds could result in a serious safety senerio. I would like to see Ford provide a real fix.

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...

Erratic behavior when semi-autonomous Blue Cruise engaged. Fault may be due to failures/malfunctions in side view mirror camera modules.

On May 14, 2022, I stopped twice on a 120 mile trip to recharge my Mach E at a level 3 DC charger. Upon completing each charge, the ring around the charging port turned red and I received a default message. I plugged my car into my home level 2 charger and the car completely locked down and I was unable to reenter the car. I have since learned that this is the classic sign of a HVBJB failure. The dealerships updated the car's programming but did not replace the HVBJB. The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contactors that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice for my vehicle 22s41. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only after damage has occurred, and...

Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only after damage has occurred, and can result in sudden loss of propulsion power at highway speed, loss of power steering, and power brakes... and failure of other 12v systems due to failure to charge the 12v battery properly after contactors are damaged. Less catastrophic results can include failure to start; which can 'strand' driver's and passengers in remote areas, bad weather conditions, as well as cause loss of use for weeks due to delays in replacement parts and local Dealerships needing equipment and training to effect removal/replacement of faulty unit with a...

My vehicle was built with under-specked high voltage battery joint assembly bracket. The failure of this connection has caused many incidents whereby the car cannot start, or suddenly stops while driving. The part is either not to original specification or was not designed correctly. In either case, providing a SW fix to simply limit the voltage does not actually prevent or correct the problem. As this fix has rolled out, there are numerous reports of the issue still happening. This is because the fix doesn't fix the original condition, it only serves to limit the scope going forward. But if the part has been in use for 2 years as mine is, then the damage has already occurred and the fix will not prevent my issue. The appropriate fix for the problem is a replacement HVBJB, which Ford is only installing AFTER the incident occurs. This is totally unacceptable and...

While legally passing a car on a 2-lane highway, at over 50+ mph, the car lost motive power and began to shut down leaving me with no power facing on coming traffic. I had no choice but to force other cars to slow down behind me, causing another hazard, in order to get to the side of the road. I could have been killed in an oncoming car collision.
