2023 Ford Mustang Mach E Owner Complaints

There was a message " Motor coolant over temperature '' popped up on 05/21/2026. Sent the car to Ford dealership for diagnosing it .Found out there was a big hole on the Motor casing . Told them, there was a crash on 04/14/2026. After diagnosing ,they did not know what caused the issue. We resubmitted the case to AAA insurance company for the sub-claim, they told me that the issue was not related to the previous crash . On the ford side, Car warranty did not cover the replacement of motor case and the repair cost. But it is really the quality issue of the part ( the casing of the motor)made by the Ford company.

Vehicle in question had problems since day. One computer was affected was never fixed. Many problems ended up in agency for repairs a total of 9 1/2 months and I’ve only have a three year lease on the vehicle and have not been able to use it fully because of electrical and further issues. Litigation found with my attorneys and Ford attorneys, that the vehicle had multiple problems and was issued by a judge, repayment and penalties.

While I was driving the brakes did not work. I had to slam on the brakes in order to stop the car. The back portion of the car then skid. The following warnings were sent to the phone and appeared on the dashboard as well. There were more on the dashboard but since I was driving I focused on trying to maneuver the car and not reading the dashboard. Not knowing what happened I continued to drive to duplicate the issue. The brakes were consistently only working when slamming on the brakes (and skidding). There was no traffic, allowing us to rely on driving slow speeds and letting the car to come to natural stops. We took it to the dealership immediately who were unable to duplicate. They diagnosed it as a network overload and attempted to release the car back to us. Currently working with a Ford Advocate as a Network Overload will shut our brakes off again. It's just a matter of when. Which is why they can't duplicate it. They can't predict when the Ford Network that communicates to the MachE braking mechanism will overload again.

The vehicle parking brake engaged as expected when parked, but would not disengage. Vehicle became inoperable and required a tow to the Ford Dealership. Ford confirmed the cause of the issue was related to a wiring fault, similar to the 2021 and 2022 model years which resulted in Ford issuing Customer Satisfaction Program 22P31. In addition, this failure caused the brake booster module to fail preventing the parking brake from engaging correctly after the wiring was repaired.

After parking the vehicle, when returning to the vehicle the parking brake would not disengage. The computer reported Parking Brake Fault Service Immediately. Vehicle was not able to be moved and required a tow to the shop as a result. The vehicle is currently being serviced, but speaking with the dealership this is somewhat of a known issue. There were no symptoms or warning signs prior to this. The only potential safety issue about this could have been if the vehicle was parked in an unsafe area and unable to be moved.

I was backing out of a parking spot in a strip mall, when I changed the gear to Drive, and moved forward by a foot. I felt a bump, as I appeared to have hit some obstruction on the left underside of the vehicle (likely a low curb/island). After that, I lost control of the vehicle - the car accelerated very hard, and I tried to stop the car, but it was not responding to my brake input. I crashed into a stationary vehicle, which deflected my car to a storefront wall. The total distance travelled from when the sudden acceleration started to the crash against the wall, was probably 20 - 30 feet (and not in a straight line). But the impact was severe enough to have deployed the air bags and the car is considered totalled. Besides the sudden acceleration which did not happen on my input, and the inability of the car to stop based on my brake input, neither did the Forward Collision Warning go off, nor did the Automatic Emergency Braking turn on, to prevent the crash.

Electronic parking brake failure after Massachusetts snow storms and salt. Car is currently at dealership so yes it’s available for inspection at Sentry Ford Medford MA. Yes it’s been reproduced. I was lucky it did not fail engaged so I was able to drive it. Early production 2023 but ford did not recall this model year. Same problem as csp 22p31. Ford currently is not covering this repair even just 500 miles over factory warranty even though all model years around it have the recall. As for the automatic emergency braking it may stop you very short, and hitting the pedal does not override the braking system. Car jerks and seems confused in this situation. I keep turning it off, but the car keeps putting it back on against my wishes. Extremely concerning as it should stay off.

Vehicle: 2023 Ford Mustang Mach-E (leased) The issue involves the cruise control system and steering wheel control layout (human-machine interface). Cruise control is unintentionally activated when attempting to use the turn signal due to the placement of the cruise control buttons. The vehicle is available for inspection upon request. On two separate occasions while using one-pedal driving, unintended cruise control activation caused sudden acceleration during low-speed turning maneuvers. The first incident occurred while signaling to turn into a parking spot. The second occurred while entering a left-turn pocket. In both cases, the unexpected acceleration created an immediate risk of collision with surrounding vehicles and required sudden panic braking to avoid an accident. The issue has occurred multiple times during normal driving but has not yet been formally reproduced or confirmed by a dealer or independent service center, and the vehicle has not yet been inspected by the manufacturer or other parties regarding this issue. No warning lamps, alerts, or messages appeared prior to the unintended acceleration. Cruise control engaged without driver intent and without advance warning.

Description of Incident: On August 3, 2025, while driving my 2023 Ford Mustang Mach-E, smoke began rising from the front of the vehicle. Within moments, flames erupted. I pulled over and evacuated. The fire quickly engulfed the cabin, resulting in a total loss. Component/System Involved: UNKNOWN. Based on the location and nature of the fire, a failure in the high-voltage battery system or related electrical components is suspected. Documentation and photos are available upon request. Safety Risk: This posed a serious threat to my safety and others on the road. Had it occurred in traffic or at higher speeds, the outcome could have been far worse. Reproduction/Confirmation: The issue has not been reproduced. The fire was investigated by my insurance company and the local fire department. Ford was notified and took possession of the vehicle on August 5. Inspection History: Ford left the vehicle uncovered outdoors for over two months. In October, they sent an engineer who spent 15–30 minutes walking around the car without opening or moving anything. Based solely on this brief visual inspection, Ford claimed the fire was caused by an “outside source” but provided no supporting evidence. I have fire report and police reports. Warning Signs: No warning lamps, error messages, or unusual behavior occurred prior to the fire. The drive was uneventful until smoke appeared. The vehicle had charged normally the day before. Assessment: UNKNOWN. The cause remains undetermined. Ford’s investigation lacked transparency and rigor. Given the growing number of EV fire reports, this incident deserves further scrutiny to protect other consumers.

Dear NHTSA Team, I am writing to urgently raise concern and seek answers regarding what appears to be a systemic safety issue affecting vehicles equipped with Advanced Driver Assistance Systems (ADAS) and self-driving technologies. I have personally experienced repeated and dangerous incidents of phantom braking, overcorrection, and loss of control while driving a 2019 Toyota Prius. The car suddenly brakes, swerves, or pulls sharply when it detects shadows, road inclinations, or mild curves — making it unsafe to drive, especially at highway speeds. These events occur without any driver error. To make things worse, this issue is not limited to one brand or vehicle. Over the past year, I have driven and rented multiple cars from different brands and models through rental companies, and many of them presented the exact same unsafe behavior — unpredictable braking, steering correction, and traction instability. This clearly indicates that the issue is industry-wide, not isolated to a single manufacturer. I have been a professional rideshare driver for over five years, completing more than 500,000 miles without a single accident or ticket. Since October 2023, these vehicle behaviors have made it nearly impossible for me to continue working safely. This situation has destroyed my livelihood — I am now three months behind on rent, my mental health has been severely impacted, and I am facing homelessness for the second time in two years. All of this has happened because of unsafe technology that drivers cannot fully disable, even when it is clearly malfunctioning. I respectfully ask NHTSA: Why are automakers allowed to release and maintain these unsafe systems on public roads? Why do drivers not have the right to safely disable malfunctioning ADAS or self-driving features, like any other electronic system that can be shut down in an emergency? When will NHTSA take meaningful action to stop these dangerous practices before more lives are affected?

I’m writing this message out of frustration, exhaustion, and genuine concern for public safety. Over the past months, I’ve been renting and driving multiple cars from different brands and models — Toyota, Subaru, Nissan, and now a 2023 Ford Mustang Mach-E — and all of them show the same dangerous behavior: •sudden phantom braking for no reason, •traction control malfunctioning, throwing the car from side to side, •unstable handling, especially on highways or during light rain. This is not an isolated case — it’s happening across several brands and systems, which makes me question what is really going on. Why are drivers being forced to deal with unreliable technology that clearly isn’t ready for real-world conditions? Are these systems being tested using real drivers as data sources to “teach” self-driving cars how to handle special situations? Because that’s what it feels like — we are being used without consent, forced to correct constant software mistakes that could cost lives. This situation has destroyed my professional and financial stability. I work as a rideshare driver (Uber and Lyft), and passengers have reported me as “unsafe” because the car suddenly brakes or moves erratically — something completely out of my control. I’ve lost access to stable work, fell behind on my car payments, and ended up returning my own vehicle because of all the expenses and stress trying to fix something that was never broken in the first place. And I have to ask: Why did NHTSA approve a regulation that prevents drivers from fully turning off these driver assistance systems? In what world does it make sense for a safety-critical technology to have no emergency off switch? In any other context — like electricity — we have breakers to stop the system when it becomes unsafe. Cars should be no different. I’ve lost almost everything I worked for because of this. Please, take this seriously. People’s lives, jobs, and mental health are being destroyed by this technology.

I’ve had this situation happen at least 2 to 3 times but specifically I’ll talk about the most recent. I was reversing out of my parking spot approximately 20 feet or so to where I can turn around and circle around the parking lot and exit. When I switched over to drive the vehicle accelerated rapidly unprompted. I was able to stop it by using the break, but I can also see how this could be a significant safety issue.

My car displayed a warning that the pre-collision assist was not available. This caused all of the safety features not to work (collision warning; lane departure warning; parking collision warning etc.) The car has been in and out of the dealership since Aug. 6th to repair this but Ford has not corrected the problem. We have not been told what is wrong with the car or any estimation on if or when it will be repaired. I requested the service documents for all of the records of when my car has been in the shop for this issue. I received the document but it has incorrect and missing information which causes me to be concerned that the issue is not being address but instead my car is being held with no efforts of a remedy. My car has not operated correctly for almost 2 months but the only service recorded was a replacement of a coaxial cable which did not fix the car.

Upon vehicle startup, the speedometer does not show on the instrument cluster (completely digital readout, analog readout not possible). In its place is the EV's remaining battery % with absolutely no way to access the speedometer and know the speed of the vehicle. This places the driver, other drivers, pedestrians, anyone else on the road at risk of excessive vehicle speed. There is no warning, error messages, or other symptoms prior to the issue happening. The only way rectify the issue is to fully restart the vehicle. However, this is not always a guaranteed fix, and the problem may persist between starts up. The issue does not occur during every start up event and is intermittent with a sudden onset (had the vehicle for 1.5 years at this point). The issue has occurred 3x in the last 2 weeks now. This issue appears to happen to other drivers of the same make / model and varying model years according to several other sources: (link 1) [XXX] (link 2) [XXX] (link 3) [XXX] (link 4) [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
