2021 Ford Explorer Brakes Problems

I am reporting a safety concern involving a delayed transmission gear engagement and delayed rearview camera activation. Intermittently, when shifting the vehicle from Park into Reverse or Drive, there is a noticeable delay before the transmission actually engages the selected gear. During this delay, the rearview camera also fails to activate immediately. Because there is no immediate indication that the requested gear has engaged, I have experienced situations where I believed the vehicle was in Reverse or Drive, but it remained in the previous state for several seconds. In some instances, the transmission engages unexpectedly after the delay, causing the vehicle to move in a direction different from what I anticipated. For example, after selecting Reverse, the vehicle may hesitate before moving, or after changing between Reverse and Drive, the delayed engagement can result in the vehicle moving in the previously engaged direction before finally shifting into the selected gear. This creates a significant safety hazard, particularly when parking, backing out of driveways, or maneuvering in areas with pedestrians or other vehicles. The delayed rearview camera activation further increases the risk because it prevents the driver from immediately seeing behind the vehicle while attempting to reverse. The issue occurs intermittently and without warning, making it difficult to predict. I am concerned that this condition could lead to a crash, property damage, or injury if the vehicle moves unexpectedly due to the delayed gear engagement. I request that NHTSA investigate this issue to determine whether it is related to a transmission, electronic shift control, or software defect affecting the safe operation of the vehicle.

While I drive my vehicle down the road the car all of a sudden sounds like you throw it in park, it screeches and grinds in the front and will not let you push the gas pedal down even when on the highway. This causes sever risk to the people around me as well as my children who drive in this car… ford has an open recall for this which my vehicle falls under year and build wise. But does not correlate with my vin #

While applying brakes coming to a stop light, the vehicle gave a message stating service brakes. The brakes still felt normal. Then after a few minutes, the brakes felt like they suddenly stopped working and then the rear tires started locking up and releasing. The frong brakes felt like they were not working at all. Stopping distance approximately tripled and not really any way to adjust braking pressure. Releasing the pedal would give a 2ish second delay before the brakes would reapply upon hitting the pedal again, and withing 1 second would lock up the rear brakes again, starting the cycle over again. Took approximately 3 applications to fully stop in a safe manner. Luckily I was already driving slow due to the warning and was able stop before hitting the car in front. Was driving approximately 30 mph when this happened. Under normal circumstances and driving distances this would have not been possible. The car was taken to the Ford. They determined there was internal failure in the Electronic Brake Booster. The fix was to replace the full assembly (EBB, ABS, etc), and flush the brake fluid. Along with diagnostics of the issue, the cost was $4,100.87 to fix. Since replacing the EBB assembly, the problem has gone away. There were no other indictions of an issue before this happened. I know other Explorer years, and other models that use this same component have been recalled for similar issues as well, and think there is a issue with this module as well.

Hi, i am concerned about the safety of my vehicle. i brought it to the attention of ford motor company and an authorized dealer that i am getting a parking brake warning on my dashboard. the authorized dealer inspected it, and said that the braking system is contaminated due to liquid spilling from the damaged cupholders. i communicated to them, that 1. the cupholders are clearly not strong enough to be placed over a critical component of the vehicle such as a braking system. 2. i think that this is a design flaw as there are normally drips and spills from having liquid in your car, especially in the designated place for it (cupholders). I should not be held liable for the repair to the braking system. they insisted this should be for my account, and if i decided not to fix it, it could lead to the entire braking system malfunctioning while the car is in motion or at a stand still. I am noting this with the department of transportation for investigation hopefully prior to an incident/accident taking place and the risk of a fatality, i have communicated to the dealer but they feel they have no accountability for this. while this may seem to be a cosmetic issue "just a cupholder", it is directly over a critical system of the car, and based on research i have done, i am not the only one with a broken cupholder in my ford explorer.

Part 573 Safety Recall Report 23V-675 The recall that is has been applied causes safety issues with the car when driving forward or in reverse. When putting the car into park the parking break auto applies. Now that is great however.. When putting the car into reverse or drive it does not release until the accelerator is applied. Now the problem is that the electric parking brake is delayed vs the acceleration causing the car to jerk forward or in reverse when the accelerator is applied. It acts like your trying to do a burn out holding down the break and it releases. This is not safe. A worker at the dealer almost rear ended a power pole in the parking lot because of this. My suggestion is to have the electric parking brake disengaged automatically when the car is put into drive or reverse. This will keep the protection of the electronic parking break being applied while in park and allowing smooth transition back to drive and reverse. Why has this issue been brushed under the rug..

All of the ADAS along with the brakes of my vehicle fail. The dealership failed to inform me of the recalls prior to purchase. The dealership in town shows all of the parts in stock in their parts department but claim not to have any parts available. When I called, I was given the runaround then sent to a voicemail. When I showed up to the dealership they stated they can only order certain amount of parts and I wasn’t on the list yet was told over the phone I was placed on the list on May 22 2024.

I hope this letter finds you well. I am writing to you regarding a persistent issue I have been experiencing with my 2021 Ford Explorer For some time now, I have noticed a loud sound when braking and when navigating obstacles such as speed bumps or when entering and exiting the ramp of my parking lot. Concerned about this situation, I took my vehicle to the service department at your dealership, where I was informed that there was a recall to replace a part related to this issue. I appreciate that you have identified and committed to addressing this problem through the recall. However, I am concerned that despite more than one or two months having passed since my initial visit, I have still not received any notification regarding the availability of the necessary part for the repair. This delay has been particularly frustrating as the problem persists and even seems to have worsened over time. The loud sound when braking and navigating obstacles is becoming increasingly pronounced, significantly affecting the driving experience and my safety on the road. I understand that manufacturing and distribution processes can be complicated, but I need an urgent solution to this problem. As a loyal customer of your dealership, I trust that you will take the necessary steps to resolve this situation quickly and effectively. Since my vehicle is my primary means of transportation, I strongly request that you expedite the repair process and keep me informed of any developments related to the recall and the availability of the necessary part. I look forward to receiving a prompt response and a satisfactory solution to this problem. I appreciate your attention and prompt action in addressing this matter.

On July 1, 2023, I had the vehicle parked on an incline with a trailer attached to the vehicle. The vehicle was in Park and the Parking Brake was set. As I attempted to unload the trailer, the vehicle started to move and rolled down the incline. I was on the trailer and was moving with the vehicle, I could have been injured but fortunately the vehicle rolled into a pile of topsoil before it could pick up too much speed. However, both the vehicle and trailer were damaged My safety was put at risk as the vehicle was moving without anyone in it. This occurred in my driveway but could have happened on a busy street. I still own the vehicle and it is available for inspection. There were no indications, warning lamps, etc. that would have notified me of the impending failure. I contacted Ford and they have been of little help. It took them 2-1/2 months to get me scheduled to have one of their field service engineers to inspect the vehicle. I was not allowed to talk to the field service engineer and that person did not attempt to duplicate the conditions which caused the failure. The report from Ford to me said they inspected the vehicle on a lift. They said they could not find a problem and said they will take no further action. They have been extremely uncooperative and do not seem the least concerned about the safety of the vehicle. I am concerned that the problem will recur and cause significant damage or injury so I take precautions whenever I park it.

I had a reputable after market brake system installed on my 2021 Ford Explorer ST at Holman Ford in Turnersville,NJ a couple years back. Since this time I have taken back the vehicle for my brakes being too spongy. I explained to the dealership that the brakes needed to be bleed again. The technician did not and adjusted the actuator on the brakes. Last year around the same time I had almost complete brake failure. This was do to the brakes having air in the lines and leaking from a fitting. The same concern I had from the beginning. The dealership fixed the problem and also added the parking brake software due to my vehicle only having one rear bolt in the subframe. Since this time, I have received numerous parking brake fault codes on my instrument cluster. The parking brake also disengages violently to the point where my vehicle lunges forward. It wasn’t until several days ago that my 2021 Explorer went back to the dealership for the parking brake issue and then saying my parking brake actuator broke apart. I have had nothing but issues with my brakes installed by the dealer and now I’m experiencing an issue caused from the software update.

After receiving a Ford issued recall for a potential rear axle bolt fracture, the dealer reprogrammed the PCM per Ford's reported repair solution. After this PCM update, the vehicle would randomly slam to a complete stop while driving. It happened several times with 3 different drivers (myself, my wife, and my son), each happening at 30-35 mph or less. It was usually preceeded by an audible clicking sound, but not always. We took the vehicle to the dealership several times, but they said they were not able to reproduce the issue, and continually returned the vehicle to us despite our grave concern for high risk of crash and injury. We even contacted Ford's customer service and legal departments several times, who ultimately refused to allow us to continue using a loaner vehicle and demanded that we return the loaner and retake possession of our Explorer because they said they had not received any other similar complaints, and their field engineer could not reproduce the issue and cleared the vehicle as safe, although Ford was never able to supply us with service records proving the repairs they purported despite our repeated inquiries. Ultimately, the issue happened again, and slammed while driving down a hill at about 40-50 mph, but this time the slamming was immediately followed by seemingly disengaging the drivetrain and causing the vehicle to roll downhill with no ability to accelerate, ultimately causing me to roll into a utility pole. Ford has since repurchased the vehicle, but given the severe safety risk associated with this issue and Ford's poor handling of our situation, I wanted others and the NHTSA to be aware in case other similar issues are reported in a effort to protect others from potential injury, especially in light of the increasing number if PCM-related issues and recalls reported against Ford...one of which was a PCM recall pertaining to our reported issue, but was not issued until after our repurchase was complete.

The contact owns a 2021 Ford Explorer. The contact stated that he recently had a manufacturer recall performed on the vehicle for Ford Customer Satisfaction Program Number 22N06 (Rear Axle Bolt Replacement). The contact stated that the dealer re-programed the E-brake to engage automatically when the vehicle was placed in park(P). The contact stated while reversing out of his driveway the vehicle would not move. The contact had been instructed to tap on the accelerator to release the E-brake. The contact stated that the RPM was raised to approximately 2,000 RPM, and only then would the high RPM release the E-brake; however, the vehicle would lurch into motion at approximately 10 MPH. The contact stated that the E-brake warning light was illuminated and then switched off once the E-brake was disengaged. The contact stated that the failure was more pronounced while reversing on a slope. The contact stated that the failure recurred while placing the vehicle in drive(D) however, the vehicle lurched and jumped forward. The contact stated that the motion was not as aggressive as while the vehicle was in reverse(R). The contact had taken the vehicle back to the local dealer where it had been reprogrammed. The contact was advised that all that could be done was to reprogram the E-brake. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 23,000.

While in a driveway at a decline (approximately 5% grade), I placed the vehicle in park and set the emergency brake; when I decompressed the brake to turn the vehicle off it took off sliding down the street. A coworker was with me and was about to get out at the time as well. Fortunately I was able to gain control before I hit the mailbox in front of us and no one or thing was injured This was the second time this happened; however, the first time the emergency brake was not set. Also, starting at 23k miles, I am repeatedly getting a "Auto Hold system fault" error every few days. This occurs sometimes at startup and sometimes while driving and the Auto Hold will not work when it comes up. However, if I stop and restart the vehicle, it will go away and work. I am not sure these are related.

Vibration: First use of the day, at about 35 MPH vehicle exhibits vibration throughout, especially around 40-41mph. Felt in steering wheel, seat, and with a loud rumble often heard. Has been since car was new. Has a vibration in rear view mirror at highway speeds. Goes away after driving for 15 miles or so, and at least a half hour. Returns after vehicle cools off. Cruise control: Adaptive cruise sometimes causes extreme braking at highway speeds for no reason. This happened while driving past a vehicle on Alligator alley causing all my passengers to comment, even though I had not touched the brake. Happened again 10/28 on 75 coming down from Sarasota. Braking: ABS engages on dry roads, especially when turning, for example into a driveway, but it cold be just a normal stop for a traffic light. The brakes also “grab” when coming to final stop, causing the car to stop suddenly
