2023 Ford Mustang Mach E Driver assistance Problems

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.

Upon hitting moderate bumps the Front Camera faults causing the collision Assist to malfunction suddenly turning off any other driving assists , even if already active such as Cruise Control, lane keeping and departure. There are many examples of the same issues happening on dedicated forums to the Mach E. TSB 23-2155 was issued but are not covered on models that are or of warranty.

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.

Incident

Feb 16, 2026

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.

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.

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)

While using ford Blue cruise I have found a major major safety flaw. While using blue cruise hands free driving over a major bridge in the middle of the day the car swerved a very hard left. Almost forcing me off the bridge. I believe the shadows that were cast on the bridge made the cars system malfunction. The incident has happened twice now and also someone else who has the same car in another state on a similar style brige with similar shadows while using blue cruise said the same thing has happened to them.

I have a 2023 Mach e premium on lease.  
I drive using single pedal mode. 
Three days ago I pulled into a parking spot in front of a restaurant in a plaza. When I took my foot off the accelerator the car came to a complete stop (as it should have ) … about a half a second later, before I could put the transmission into park, the vehicle went full throttle and jolted forward up over the curb onto the plaza sidewalk and crashed into a full brick column. I slammed on the breaks as fast as I could, but if the brick column was not there, we would have crashed into the restaurant. There is damage to the front drivers side of the vehicle. The airbags did not deploy. The beeping sensors never went off. Honestly, the experience scared the crap out of me. We’re lucky no one was injured. 
Ford has the car at the dealership now. 
they told me that something seems to have malfunctioned. They told me that the car should have deployed the airbags, the sensors should have went off, a deceleration stamp should be logged in the vehicle data and it should be telling ford that the car experienced a collision. None of that happened. 
needless to say, they are now telling me that because they can’t mimic the problem, Ford is instructing them to return the vehicle to me. 
they have nothing to repair, and are not taking ownership for the damage. I honestly don’t want to take the car back. 
my wife isn’t comfortable driving it anymore as she feels it’s a safety risk.

The Mach-E alert systems does not alert the driver if there's a pedestrian close by. The alert system alerts for vehicles only not pedestrians. I would like to see the car have same alert sensitivity for pedestrians as it does for vehicles. Also, when changing lanes lights on the side mirrors have warnings that a vehicle is close by. Ford should add an audible warning like beeping or ringing sound along with the lighted icons on mirrors.

A software glitch is causing lag in the instrument panel which displays the speed and turn indicators. Both are experiencing 'lag' or 'skipping', so the speedometer is not updating in real-time and regularly displays inaccurate speed information. To elaborate, as I accelerate, the indicated speed jumps with the worst experienced so far being 28mph to 60mph. The car will do the same decelerating. The turn indicators/hazard light indicators are also lagging and not displaying correctly. The Ford dealership was not able to resolve the issue after resetting several systems and attempting a software update.

It is far too easy to accidentally hit and activate cruise control button on the steering wheel when turning. If your thumb brushes up against the button the car can continue moving when you expect it to be slowing down either coasting or staying at the same speed when using 1-pedal driving. This could easily cause an accident when coming up to a turn and someone is crossing the street or similar situation.

While driving the 2023 Ford MachE in 1 Peddle mode Friday 12 July 2024. I had to suddenly brake due to a car cutting of the car in front of me to make an illegal turn. I applied the brakes (HARD) and my car came to a complete stop. Just as I was breathing a sigh of relief, and waiting for the still parked car in front of me to move. On I released my foot of the brake (the car should have held in place). However, warning lights sensors started beeping going crazy as the car lunged forward. It caused me to hit the car in front of me. The lunge was so forceful that for a moment I thought another car had rear-ended me and pushed me into the stopped car in front of me. I did not have time to see all of the alerts flashing on the dash as they were flashing as the car was propelled forward. The other car did not sustain any damage. However my car car did. While waiting on the Police to come make a report I did use the in car engineer feedback and recorded a message notifying Ford that my car had lunged forward. On Monday 15 July I called the Ford BEV team to tell them what happened. Was advised to take it to a dealership to be checked out. The dealership ran diagnostics and updated the car via a technical service bulletin. 24-2187 issued on 07 June 2024. Prior to me taking my car to the dealership I also came to your website and there were no active recalls and no mention of this bulletin. The bulletin address the 1 pedal drive fault. I was not aware of this TSB. I have documented over 50 posts related to this error and fail.
