2023 FORD MUSTANG MACH E Complaints

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.

After stopping the vehicle to run an errand, the vehicle locked up. The steering wheel would not turn. The vehicle would not shift into any gear. The vehicle was inoperable and I found myself stranded 25 miles from home. The vehicle was towed to our local Ford dealership where it has been for the past two weeks. This failure could just as occurred on the road causing a dangerous situation.
