2024 FORD MUSTANG MACH E Complaints

Vehicle has a bearing noise in the front. Now vehicle has door fault, transmission not in park, auto hold fault and hill assist not available when driving the car. The car will engage parking brake randomly and when the brakes are wet the brakes will not engage for up to 50 feet. The car has become extremely unsafe and unpredictable. Ford’s road side assistance keeps delaying any tow and finally had to cancel the tow as I have to work. Need help badly with this!

Purchased new 2024 Ford Mach E on 03/31/25. Had 15 miles when purchased. On 04/10/25 at 185 miles on odometer, car experienced 2 malfunctions, Powertrain and High Voltage. This placed the car at alternating restricted speed of 5-12 mph on a highway. Towed vehicle to dealership same day as unsafe to drive. On 04/18/25, dealership technician cleared the Diagnostic Trouble Codes and stated that they were unable to recreate error condition, therefore wanted to release the car as is with no recommended fix. The technician called it an "intermittent" Trouble code.

The HVBJB failed on my 2024 Ford Mustang Mach-e. I first noticed a dashboard warning regarding a powertrain malfunction when I tried to start the car about a half-hour after we returned home from an approximately 170-mile drive five days ago. The warning said it was a powertrain malfunction and to get service soon. The car started an hour later and I was able to drive it to the Ford Service center where I bought the new car only last June. There they diagnosed the problem with this language: "HV JUNCTION BOX - FOUND P0AA1:68 AND P0AA1:00 TO BE HARD SET AND THE TO BE IN LIMP MODE. NEED TO REPLACE HV JUNCTION BOX ( 414-03A PPT P4 ) AND RETEST ALL MODULES. WILL NEED MORE TIME AFTER REPAIR TO TEST ALL SYSTEM. MEY NEED TO TAKE APART HV BATTERY AGIAN..." The service people told me that they need to keep the car for two weeks to replace the part and conduct follow-up tests. I know that the failed component has been the subject of two past recalls (2022, 2023) of the 2020-2022 model years for the Mach-e. The first recall resulted in Ford's attempt at a software fix, while the second required replacing the HVBJB in cars in which the software fix proved insufficient, presumably because the part had already been damaged before the fix and later failed under heat stress. Based on my experience this week it seems clear that neither recall resulted in Ford fixing the underlying problem with the part. Importantly, Ford says the part is subject to failure from overheating when drivers too often use high speed chargers (DC) or too often employ maximum acceleration. This admission contradicts Ford's own marketing of the car, which emphasizes its sportiness and fast acceleration, and its compatibility (with an adapter) with Tesla's large national network of superchargers. So the nature of the failing part is apparently wholly incompatible with what attracts many buyers to the car. Can NHTSA require Ford to make the necessary engineering fix to the part?

What component or system failed or malfunctioned, and is it available for inspection upon request? The high-voltage battery system and powertrain system both failed. The vehicle went into limp mode, showing alerts for “Powertrain Malfunction / Reduced Power” and a “High-Voltage Battery Warning.” The vehicle is available for inspection if requested. How was your safety or the safety of others put at risk? The incident occurred while driving on the freeway at 75–77 mph, which significantly increased the risk of a crash. The sudden loss of power in heavy traffic was dangerous and could have led to a collision. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The issue has been documented through the Ford app and in-vehicle warning messages, and I am in the process of waiting for a diagnostic to be completed by the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Waiting for dealer to look at it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, immediately before and during the failure, the vehicle and the Ford app displayed messages indicating a powertrain malfunction/reduced power, along with a high-voltage battery warning alert. Additional description: While driving on the freeway at approximately 75–77 mph, the vehicle suddenly entered limp mode with a dramatic reduction in speed and power. Warning lights for a powertrain malfunction and high-voltage battery appeared. This created an unsafe situation in high-speed traffic. The vehicle had approximately 1,459 miles at the time of the incident. This also happened on my 2022 ford mustang Mach E 8 other times.

The contact owns a 2024 Ford Mustang Mach E. The contact purchased a Nivion Tesla charger adapter and received notification of NHTSA Campaign Number: 25E001000 (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 dealer was not contacted. The manufacturer was contacted; however, the contact was only able to leave a message and had not yet received a response. The contact had not experienced a failure. Parts distribution disconnect.

New car making 65-75 db loud constant clunking noises when turning steering at stopped. 1st dealer visit, it said it’s normal because they have other of same model making same noises. 2nd visit, dealer said it’s noises from brake binding and it’s normal and showed me another car of same model making same noises. Problem is not resolved. When brake pedal is pressed, there shouldn’t be binding on new car. Binding means brake pad is slightly touching the rotor when brake pedal is released. When pressed, pads should firmly grip the rotor. Not gripping firmly means the caliper is pushing the pad against the rotor. Uneven brake pad shouldn’t be causing it either since it brand new. And it’s not brake bedding-in either. It’s now at 1944 miles. Brake binding is what the dealer say but could potentially be suspension problem and there are more of this model making same noises. No waning light. There were 3 times when it pulled to one side when driving straight. I have videos of the clunking when turning steering.

Turned car on, dashboard read 2 errors of "rear cross traffic sensors fault" and "blind spot monitoring fault". They cleared, drove the car, while driving the dashboard and infotainment went dark. Drivetrain and brakes still functioning but without speedometer and state of charge. Was able to turn around and go back home. Attempted reboot, so far nothing has fixed it.

Was driving when the driver instrument display went blank and is no longer functioning. This display shows speed of vehicle and other status information, such as battery level, range and cruise control status. There has been a software update remotely installed today, which may be a coincidence.

I bought my vehicle in late June and in mid august, we notice the body started becoming rough to touch. It went from smooth and sleek black body to rough and spotty.

While driving the vehicle electrical console started flashing then lost power and stopped dead in the road. The battery was reading between 70% to 80% prior with a range of over 250 miles still available. Due to complete lack of any power the car could not be moved or placed into neutral for towing. It caused a traffic situation blocking 2 lanes of traffic for approximately 4 hours waiting for roadside assistance for jump start and towing. EV's cannot be towed like a regular car and not having access to the electronics made the car like a brick. Eventually I was able to attain assistance with a jump start that was able to provide enough power to drive onto the back of a tow truck and to the Ford dealership. Roadside assistance noted the 12-volt battery at the front of the vehicle was bulging and potentially overheated creating a potential explosion hazard and lack of electrical support to the main vehicle.
