Owner reports

Selected complaints filed with NHTSA by 2022 Ford Mustang Mach E owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2022 Ford Mustang. The contact stated while pulling into a parking spot at approximately 2 MPH and had not yet placed the vehicle in park, the vehicle had an unintended acceleration. The contact stated no warning light was illuminated. The vehicle crashed into a light post, ran over the post, and crashed into a back of a building. The vehicle had damage to the hood, grill and bumper and also to the undercarriage. The contact said he had not suffered any injuries. The police were on the scene and filed a report. The contact had the vehicle towed to a collision repair shop. The vehicle had not been diagnosed by a dealer or independent mechanic. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 22V333000 (Vehicle Speed Control, Power Train). The manufacturer had been informed of the failure. …

The contact owns a 2022 Ford Mustang Mach-E. The contact stated that while driving at an undisclosed speed, the vehicle became inoperable and the vehicle stalled, and the gear shifter was inoperable. The contact exited the vehicle and was unable to re-enter the vehicle because the doors were locked and failed to unlock. The messages "Service Now" and "Battery Management" were displayed on the instrument panel. The pre-collision sensor warning light and several other unknown warning lights were illuminated. The failure had occurred on several occasions. The vehicle was towed to the residence, and the batteries were replaced. The contact researched the issue and became aware of an unknown recall; however, the VIN was not included. The vehicle was taken to a dealer, where it was determined that the battery management system needed to be reset. …

Car was stopped at the top of a hill. Driver put the car in park and exited to talk to a security guard to raise a security barrier. Car began to roll down a hill and didn't stop until it hit a metal security gate 250 yards away. Car was totaled as result of collision with gate. No one was hurt. It would appear that the transmission/engine did not stay in park and began to roll and that none of the other safety features stopped the car. There were no passengers in the car at the time of the accident and no airbags went off.

On November 18, 2022 my vehicle's High Voltage Battery Junction Box (HVBJB) failed. Ford replaced this part with an "upgraded" version of this part and I received my car back on November 28th. Shortly thereafter, the NHTSA issued a recall, the solution for which was a software update that my car received. On October 10, 2023 my vehicle's HVBJB failed once again (the newer upgraded part). Coincidentally, while my car was in the shop, the NHTSA issued a second recall for this issue, indicating that Ford would be recalling the physical HVBJB. Shortly after this recall, my recall was marked as complete because I received the upgraded version of the part once again. …

My vehicle dash displayed "vehicle not in park" multiple times immediately after I put it in the drive position. At times I could push the "ok" prompt and proceed to drive but when I slowed or. stopped at intersections it would occur again and sometimes it applied the park brake without any action on my part. Around the same time I started getting "door module fault" or "door lock fault" warnings. It's been at a dealer over a month so I don't recall the exact wording now. The dealer diagnosed the vehicle and determined the door module fault made the vehicle think it was moving with the door open and replaced it. After the repair they're now saying it's unsafe to operate because while in their custody it's automatically applying the brake and displaying a "shift indicator module fault" that also requires replacement. …

I have a 2022 Mustang Mach-E GT and have now experienced two (2) High Voltage Battery Junction Box (HVJB) failures. First failure was in July 2023 when the vehicle had approximately 12,000 miles. I received the stop safely now message. Vehicle codes displayed via the Ford app showed a High Voltage Battery Warning and Power train Malfunction / Reduced Power warnings. I have now received this same failure and warnings again. The car currently has 54,000 miles and I was just advised by my dealer that the HVJB has failed a second time. My concern is that the replacement voltage boxes are nothing more than a Band-aid for the problem and not a permanent solution. As I prepare to receive by 3rd HVJB, I feel this is nothing more than a temporary fix until I receive another Stop Safely Now message while operating my vehicle. Please look into the HVJB failure rate for these vehicles. …

I was driving on the freeway when out of nowhere the vehicle alerted me to "Stop safely now". I no longer had any power and could not accelerate. I was doing 70 MPG in the middle lane and had to switch to the right lane, then to the shoulder of a busy interstate. This was extremely dangerous as I was losing speed quickly, and luckily had no one to my right side. If there was traffic I would have been at risk with anyone to my right also at risk. Once I was on the shoulder I tried to restart the vehicle with no success, eventually it just completely lost all power. This vehicle is full electric and had 76% charge at the time of the incident with 23,642 miles. I am very dissatisfied with how unreliable this vehicle was by just turning off in the middle of the road. The worst part was Ford roadside assistance took over 5 hours to get the vehicle towed to the dealership. …

File against: Ford Motor Company Vehicle: 2022 Ford Mustang Mach-E VIN: [redacted] Safety Complaint While driving, the vehicle unexpectedly slowed down, lost power, and became inoperable, creating a serious safety hazard. I was able to pull over safely, but the sudden loss of motive power occurred during active roadway conditions. Dealer diagnosis identified a wiring harness connector failure affecting communication between vehicle control modules. After the repair, the same issue reoccurred within one to two days, again causing loss of power. The vehicle is currently back at the dealership, and the underlying defect has not yet been permanently resolved. This recurring electrical failure represents a loss-of-motive-power safety risk that may indicate a broader wiring harness defect affecting vehicle reliability and safety. Thanks and Regards

While driving on Route 1 and attempting to pass another motorist, a flashing red "STOP SAFELY NOW" lit on my dashboard, along with multiple warnings of a "powertrain failure". Thankfully I was near my house and was able to get home. But the FordPass App is saying that I had a high-voltage power malfunction and will need to tow the car to my local dealership. Now I am being told that the high-voltage junction box has failed and needs to be replaced (consistent with Ford Recall notice 23S56). Unfortunately, Ford hasn't produced a replacement part, and after speaking with multiple dealerships, I have been told that an updated replacement part may not be available until Q1 2024 (Or between 6-18 weeks from now). Those of us who purchased these vehicles now have $65K+ paperweights. Ford should buy back these cars, fix them, then resell them through local dealerships. …

At highway speeds, the power brakes failed. In order to slow the car down, the brakes pedal had to be modulated with extreme force, upwards of 100 pounds of pressure on the brake pedal. As this happened, the car raised 4 Active Alerts - Powertrain Malfunction / Reduced Power - Antilock Brake Fault - Hill Start Assist Warning - Pre-Collision Assist Not Available. It took a lot of force and distance to bring the car safely to a stop. After 20 minutes we restarted the car and it began to operate normally. The car was brought to a nearby dealer immediately, however, the dealership is unable to diagnose nor replicate the problem. ***We were extremely lucky there were no cars immediately in front of us, and that we have an extreme amount of room to stop. Had we been driving in traffic, there would have been an extremely high likelihood of an accident with injury.
