2021 Ford Mustang Mach E engine problems

Filed Aug 6, 2026 · Electrical, Engine · NJ

The HVBJB ($3500 + Tax) went on my car. It is out of battery system warranty by 25,000 miles (ended at 100,000 miles, I have 125,000 miles). I called Ford Corporate and they said they "have no current programs" to give me any good will discount on the repair. This is a big, known issue with Mustang Mach-e's There was a recall for this HVBJB part / system on many of the 2021 models, but somehow mine wasn't included in the recall. I cannot afford this repair, and I was hoping the federal safety agency can get involved to get me some financial relief from Ford. There was also a safety issue as this morning when this all happened, the car forced me to stop at an intersection and would not move or restart. The police had to push me through the intersection. It's currently at Chapman Ford in Egg Harbour Townshop, NJ.

While driving my 2021 Ford Mustang Mach-E, the front electric drive unit failed suddenly with no warning signs, warning lights, unusual noises, or any prior indication of a problem. During the failure, multiple fault messages appeared on the instrument cluster, including warnings that disabled adaptive cruise control and indicated the all-wheel-drive system was no longer functioning. The vehicle began to vibrate severely, feeling as though it was driving over rumble strips. As I slowed down, the front of the vehicle became extremely clunky and exhibited abnormal drivetrain behavior. Shortly afterward, the vehicle became undrivable and could no longer be operated under its own power. It had to be towed to a Ford dealership, where I was informed that the front electric drive assembly had failed and required replacement. This is the second time this exact component has failed on the same vehicle. The first front electric drive assembly failed at approximately 33,000 miles and was replaced under warranty. The second failure occurred at approximately 102,000 miles with no warning. I believe this repeated and sudden failure of a critical drivetrain component presents a significant safety concern because it can leave drivers stranded without warning and results in an unexpected loss of propulsion while operating the vehicle in traffic.

On April 19th, I picked up dinner and when I went to leave the parking lot, my vehicle turned on, but did not allow me to move out of park, nor shift into any other gear. I turned the vehicle on and off about ten times to see whether that might allow me to shift into another gear, but to no avail. It was later in the evening, so when I called the Ford customer service line I received an after hours message, and then thereafter I received a call from a Ford customer service center caller saying that they saw I was "stranded" and would send a tow truck to take the vehicle to the nearest Ford mechanic shop. They picked the vehicle up around 11pm in the evening. While the vehicle has had numerous other recalls, (windshield, etc.) I had not received any recall notice related to a battery issue. The dashboard showed a wrench in a car symbol as well as the battery symbol and a note that said "Stop safely now," and "full accessory power active." For the two and a half weeks following, I was not told what was wrong with the vehicle, nor was I provided a courtesy car. When I requested rental coverage, I was informed I would have to call "corporate" in order for them to cover the request, and when I did reach them, I was told that until they diagnosed the vehicle, they could not tell me whether it was my fault or theirs. After weeks of going back and forth, they agreed to cover a Ford rental (that I had to find on my own,) but have still not been given my vehicle as I have been informed that there are program wide software holds on the vehicle that prevent the technician from working on it. My lease ends in another month, and I have not been provided any information as to what my options are, or whether the vehicle will be fixed. I was also informed that I was not eligible for the Ford repurchase program as the vehicle is over the allotted 2 year/24K mile period, but I am extremely frustrated by the lack of care Ford has shown for my safety and ability to get around.

I have complained several times with Ford Dealers to fix the issues involving my vehicle accelerating on its own. The vehicle within a week will accelerate on its own 4-6 times when exiting a parking spot or my driveway.

I have experienced multiple powertrain malfunctions since the original recall for this issue was completed back in 2022. Approximately 4-5 of these warnings were temporary and cleared within a few hours or after a visit to the dealer to diagnose. Most dealer visits yielded nothing as the car had cleared the errors and codes it was throwing. In 2021, I experienced a complete vehicle failure with a "Stop Safely Now" and "High-Voltage Battery Warning", right before the original recall was performed. My most recent malfunction has also caused a complete vehicle failure, exactly like what happened in 2021. I am concerned that these issues will continue and eventually happen while driving, creating a massive safety issue.
