2023 Ford Mustang Mach-E RWD

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.

Parking brake fault service required, release parking brake messages when brake is not engaged.

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.

"Parking Brake Fault - Service Now" warning appeared. Parking brakes locked after stopping vehicle. Dealer diagnosed problem as corroded wiring connector to left rear wheel parking brake motor. Vehicle has 41,000 miles. Vehicle was stuck and could not be moved. If this had occurred in traffic situation a crash could have resulted. Charge to repair was $600 because dealer claimed brake parts are a "wear item".

Diag and replace left rear parking brake actuator pigtail. Corrosion and breaking of the wire, causing the parking brake to be stuck. This was a recall on the earlier models (2022), and seems to be an ongoing issue. It is not covered under warranty over 36k miles.

Parking break fault message appeared on the vehicle and the parking break was stuck on, making it impossible to release the break and therefore move the car.

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.

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)

The contact's husband owns a 2023 Ford Mustang Mach E. The contact stated that while her daughter was driving at an undisclosed speed, the vehicle that was in front of the vehicle stopped abruptly. The contact stated that the driver depressed the brake pedal, and the vehicle started decelerating. The contact stated that Automatic Emergency Braking system then engaged, and the vehicle stop decelerating and crashed into the rear end of the other vehicle. The contact stated that the vehicle sustained severe front end damage, but no air bags deployed. No injuries were reported. The other driver exited the vehicle, returned inside the vehicle and drove away from the scene. A police report was filed, but the police report number was not available. The vehicle was able to be driven away from the scene. The vehicle was taken to an autobody repair shop to be repaired. An unknown dealer was notified of the failure, but no assistance was provided. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the incident. The failure mileage was approximately 12,000.

The contact owns a 2023 Ford Mustang Mach E. The contact stated after driving 15 MPH and then attempting to reverse, there was a clunking sound coming from the vehicle while reversing out of the driveway. There were no warning lights illuminated. The contact towed the vehicle to a dealer where it was diagnosed and determined that the brake pads and rotors had delaminated. The dealer informed the contact that the brakes were not covered under warranty. The vehicle was repaired. The manufacturer was made aware of the failure and informed the contact the repair was not covered under warranty. The failure mileage was approximately 11,000.

Was driving on hightway another vehicle was hit by a truck and sent ti my lane. Y hit it almost head on. My vehicle tire and front axle was ripted off. My side or car also damaged. Cas was total loss. No collision light and no air bags deployed

Intermittent issue with the driver seat belt sensor which illuminates the restraints indicator warning light. Message sent in FordPass app says: "The restraints control module has detected a fault with the driver seatbelt buckle sensor circuit" Consultation with the dealership indicated that when the restraints warning light is illuminated the airbags become disabled. However, stopping the vehicle, turning it off, removing and reinserting the seatbelt into the buckle, and starting the vehicle clears the warning light. This is extremely intermittent and replication is difficult.

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.

The contact owns a 2023 Ford Mustang Mach-E. The contact stated while reversing out of the driveway, an abnormal sound was heard coming from the rear of the vehicle. Upon further inspection, the contact noticed that the rear passenger’s side brake pad material had separated and was stuck on the rotor. Additionally, the contact stated that the vehicle was outside in the rain a week before the failure. The vehicle was towed to a local dealer where it was diagnosed that the rear driver’s side and the rear passenger’s side rotors and brake pads needed to be replaced. The vehicle was not yet repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 18,000.

There was a software update released in July that drains the 12 volt battery and locks you out of thr vehicle. The reddit forums are calling it the "lockout glitch". It has to be towed to a dealer in order to even get into the vehicle.

I am locked out of the car despite having keys and phone in hand. When I was in the car it wouldn’t start. Screen was black. I got out of the car to try other doors. When I got back to driver door, the car was locked and I tried all normal modes to get in the car. It is NOT the 12 volt battery. I tried to use the manual jump to get the hood to pop open but it didn’t work. If I had a baby in the car and it was hot out, this could be a life-threatening disaster.

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 recall campaigns needing VIN-specific checks 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.

The dash screen is blank and dead since 2 days. Also i am getting the airbag disabled notification. There is no way to see the odometer and speedometer. Also the dash screens keeps rebooting while driving.

My vehicle has no driver screen. It completely went black. Cannot monitor my speed or check anything on the dash screen.

I just bought mach E. [XXX] I was in car line at Macdonalds to get food for my 14 year old son. The speeded itself to full speed. I luckily had both hands on wheel. I turned car to left away from car in front of me. Luckily I was able to put my foot on brakes and able to stop the car but not before killing couple of plants on curb. I manage to stop car just couple of feet away from building. In process I burst my front left tire and had to tow the car to nearest shop to get tire replacement. I complaint to Ford. Made sure they document everything. They haven't paid any attention to my calls and want me to pick car from dealership without getting into why it happened. Before this happened I noticed at least four times the car speeds up when you press cruise control button even without setting the set up button. Ford is not willing to do anything about it and I am scared to drive that car the way it shot at me and itself speeded while I was in car line.

Whenever it rains the brakes on the ford Mac-E get stuck to the rotor. The car will not move unless you apply pressure to the pedal and accelerate. The car makes a clicking noise and it’s visible damage to the rotor and stoping isn’t smooth.

This vehicle has a one-pedal drive mode that uses regenerative braking to slow / stop the vehicle when you remove your foot from the accelerator pedal. On several occasions, this system has suddenly turned off with an error message displayed on the screen. This means that the braking that I was experiencing at the moment suddenly ceased. This is a dangerous situation that could result in an accident. Ford indicates it is a known issue, but currently does not have a fix for it.

Brakes: The brakes grab hard when coming to a stop and cause a slight jerk. I have reported this issue to the original dealership of purchase; Angela Krause Ford in Alpharetta, GA. It’s been two weeks since I purchased this vehicle brand new and I still have not been able to get it in for repair. Charge Port Door: The charge port door cover came off while I was trying to close it and the clip part that connects the door to the car and locks came off (very cheaply made and other Mach E owners have suffered this same thing shortly after purchase). I can’t drive the vehicle because of the brakes issue and also because with the slightest wing going down the highway the charge port door pops open. I have it secured with a piece of tape currently but that’s still not safe or secure and the door could still fly open.

Brakes grind when coming to a stop at low speed or may not disengage from a stop at low accelerator input. Note auto hold/parking brake feature disabled. Appears to be oxidation and rough surfaces on brake rotors. Car has approximately 2700 miles and has done this since new.

When driving, sometimes a “Drive Mode Unavailable” message comes up on the infotainment. Drive modes in the MachE contribute to deceleration, one pedal driving, and throttle mapping, and switching abruptly from one to another without input from the driver is a safety issue as it can instantaneously change the deceleration or acceleration rate of the vehicle. This is a known bug that’s been around for years and still no fix for it.

The vehicle regularly, and at random times, will drop out of the chosen drive setting and go to the default "Engage" mid-level setting. This changes the driving dynamics, such as pedal pressure required to move the car, and the sensitivity of the steering. If the driver was in "Unbridle", for example, the car will immediately lose speed and steering sensitivity, while if the driver was in "Whisper", the car will lurch forward. This has happened at city speeds, highway speeds, and even while at a stop in a line of cars. The stop is especially dangerous, as 1-pedal drivers would expect the car to be fully stopped, but it still lurches forward towards people or other cars. Temperature of the engine and battery does not seem to be a factor, as this happens in all conditions. It appears to be a dangerous software error.

On Saturday July 15, 2023 my family and I were in the car going grocery shopping. By time I reached the grocery store a warning came up on the screen that stated brake fluid low. When I arrived home I did not have any brakes. The vehicle was towed the dealer where it was purchased. I was told that the brake caliper were faulty and their is only one mechanic that is allowed to work on electric vehicles.

The contact owns a 2023 Ford Mustang Mach E. The contact stated while driving at an undisclosed speed, the brake fluid warning light illuminated. Additionally, the contact stated that the brake pedal floored while depressed, and the vehicle failed to stop immediately. The vehicle was towed to the dealer, who informed the contact that the calipers had failed. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 237.

The car is accelerating by his own, without having the cruise control on and this happened a couple times, mostly after a full stop on a red light, until you don’t make a manual full emergency break it won’t stop. It can cause death if it accelerate it by his own, also couple times the front camera has a fall out and he’s warning the pre collision even no car is in front of you
