The Adaptive Cruise Control will arbitrarily reduce speed for no apparent reason. This has happened on several instances. Sometimes the vehicle just slows down and other times the brakes are suddenly applied. The vehicle speed has been suddenly reduced by 20 MPH on a busy 65MPH road in rush hour. No accident occurred. Vehicle was in service just this past month. All updates were entered and several flaws were corrected. Problem has continued up to and including this morning. No warning lamps or collision avoidance alarms were triggered.

There is a front camera default which is causing the following to not work. Adaptive cruise control Blue Cruise Auto High Beams Lane keeping assistance pre collision warning with auto braking
I repeatedly get two error messages, front camera fault and pre collision assist unavailable. It happened randomly until it finally went out completely. I've spoken to many other owners who are having the same problem and it seems that there is not fix. This causes the cruise control and lane keeping assist to become unavailable. Myself and many other owners have attempted to get this issue resolved multiple times and it seems that there isn't a fix and the manufacturer is not speaking out about it. My car is currently at the repair shop for it's 3rd visit to resolve this same issue. The dealership is unaware of how to resolve it and are waiting for Ford to find a resolution. This has been an issue since April and the repairs attempts started when the camera went completely out in May. This is a big safety issue if the care can not pick up the threat of a front collision. With the pre collision assist unavailable it something were to happen while driving, the emergency brake system will not activate. I feel that this issue should be addressed.
Ford has recently released a software update that causes Front Camera Faults when going over bumpy roads and across multiple conditions. This causes the Blue Cruise cruise control system to suddenly stop working when driving at highway speeds. When coupled with One Pedal driving, this could cause brakes to slam on while driving at highway speeds. Additionally, forward emergency breaking does not work until this fault resets (after ~1-2 minutes typically). This happens constantly when driving and causes safety hazards.
Two problems on multiple separate occasions occurred. 1st problem - more than twenty (20) times car had suddenly accelerated or slowed down while driving with cruise control. This supposedly should have been resolved with an update that was downloaded around a month ago. Nothing changed, car still accelerates or slows down randomly. 2nd problem - occurred at least five times. Car suddenly loosing power while entering the traffic including entering highway. Drivetrain malfunction warning was displayed on dashboard after last lost of power when entering intersection. After latest incident on September 13th car is being repaired at the dealership.
The hands-free steering control Does not give a loud warning or much notice as it shuts off quickly as it did to me as I switched from southbound 805 to southbound 163 in San Diego. The hands-free steering veered off of the 163 entrance ramp towards the crash barrels and I was barely able to get control and avoid a crash. About 5 miles further down the road as it was going hands-free on 163 underneath interstate 8 and there is a curve to the left but my vehicle kept going straight and I barely missed other cars in the next lane as the hands-free steering suddenly stopped with no loud notice. Luckily, I was paying very good attention which is hard to do when you’re talking to other people in the car and driving hands-free. I had less than two seconds notification to take full control and avoid a wreck. My brother was a passenger as I was taking him to the airport. In the past I have been qualified as a professional racecar driver and I have a masters in mechanical engineering and have much experience with electronics as I produce electric vehicles . I also owned a Tesla model three for a couple years and the autonomous driving was scary on it at times. My wife would not let me put it on autonomous as these vehicles are back-and-forth in their lane so much that passengers get scared. I am selling my 2021 mustang Mach-E before it kills me. I love the car and the handling and acceleration but after the dealer installed this hands-free, I am scared. The two incidents today and several other minor ones before tells me there’s a lot of development still needing to be done before these hands-free and autonomous devices are allowed on even Controlled access freeways.
When placed in drive the car takes off on its own without the acceleration pedal being touched. The passenger locks only work with key fob unlock button being pressed and the passenger side doesn't recognize the Fob for easy entry. The adaptive cruise control warning comes on constantly. The handas free parking never worked since i got the car in July 2021.
On approximately March 20, 2022, I was driving my Mach E vehicle. I pulled into a driveway and parked my vehicle. Upon exiting my vehicle, my vehicle began accelerating forward up the inclined driveway. It then struck a parked vehicle and came to a stop. The car accelerated uninetentionally which is in alignment with the current recall. Additionally, the advanced emergency braking did not work as the brakes did not deploy and the car only went back to rest after I re-entered the car post-accident.
While parking in a garage the vehicle unexpectedly accelerated and ran into a wall. Anyone in or around the car may have been seriously ignored. The issues has happened twice but can not be reproduced by me. There we no indicators that the event was about to take place There is a recall for this on the vehicle type but not for the date of my manufacturing.
No clear sound or indication when BlueCruise disengages leading to unexpected behavior.
If any of the passengers are unbuckled and the seat chime is on the car does not have an audible forward collision or pedestrian warning alert sound.
While driving on thruway, it began to snow.. One. by one the safety sensors reported failure due to being blocked. Even basic criosese control stopped working. As conditions cleared none of the sensors recovered. I pulled off at an exit to clear any remaining snow that may have been blocking the sensors. The sensors were already clear, yet still reported. being blocked. I pulled into a car wash and. had the car washed and dried to make sure that every sensor was unobstructed. All of the sensors were still in a failure state. Not one sensor recovered. I had to turn off the car and restart to clear the sensor failures. This is a big problem when driving on a long trip. Every time it snows and a sensor fails, I have to exit the thruway and find a place to pull over and restart the car. In instances where roads are wet, cars ahead spray road mud and block the sensors. This happens constantly in upstate NY. Every few miles when the sensors is blocked the car will lose cruise control and most of the safety features. The only way to recover is pull off of the road to restart the car. It happened, several times on 50 mile drive. It's unnerving when it does. When weather conditions are poor, I want to get to my destination safely, without extra driving caused by exiting to restart and merging back on the thruway multiple times. Any other modern vehicle that I have driven will clear a sensor failure when the condition no longer exists, without restarting the car. The Mach-E refuses to clear sensors unless it's restarted. I do believe this compromises the safety of the driver and passengers by causing unnecessary extra driving with multiple instances of stopping and restarting while road conditions are ready poor.
When I start up the car, and the temperature is below 50 degrees, the "pre-collision assist" is not available, the "park aid" malfunctions and the "blind spot detection with cross traffic" is inoperative....the alerts are on the dash, and come as alerts to my phone. The car can still be driven. My car has been at the "service" department at the dealership since march 16, and I have no word on when it will be returned. This has happened 2/26, 2/27, 3/2, 3/4, 3/5, 3/6,3/7,3/10 and 3/12. And, twice, while driving at warmer temps., the "front collision alert" has suddenly appeared on the dash, and there is nothing in front of me.
