This has happened multiple times. Start the vehicle and put into drive while the brake pedal is fully depressed and the car will move forward. While it is in motion you can hear what sounds like the anti-lock system activating. You have to pump the brakes as I assume the master cylinder has lost pressure. It does this randomly and is not repeatable. If this ever happens and someone or another car is around it could be a very bad day.

I was driving down the road and several sensor malfunction warnings started to pop up including an antilock brake fault. I was in traffic and needed to slow down but the brake system was non responsive when I applied normal pressure to the brake. I had to attempt braking with all my force before car slowly started to brake. I nearly was in an accident but fortunately was able to pull off to the side until car was able to fully stop.

It has happened several times over last year. When car is put in reverse the brakes barely work and car doesn-€™t stop well. Almost like no power brakes. Once put in drive, the brakes work correctly.

- West Columbia, SC, USA

Rear backup camera incorrectly sensed an obstruction behind vehicle and caused emergency braking with no visible obstruction. We were unable to pull out of the parking spot and had to jump a curb to leave. No further incident has been experienced,

- Centereach, NY, USA

While driving at 70 mph the vehicle experienced the following issues all at once, the power steering shut off, all brake pressure was lost, the pre- collision system was turned off, parking brake engaged(at 70 mph) traction control system turned off, engine light turned on and all of the warning lights on the dash activated. This has happened 3 times and almost killed me twice. Ford has tried to repair this vehicle all three times and still have not corrected the issue. Ford has also refused to replace or buy back the vehicle.

My new 2020 FORD EXPLORER had had on at least 4 occasions, the last being in July 2021 (mileage was approximately 7,280 miles at the time). This problem has only occurred when parked in my garage, I turn on the Explorer with my foot firmly on the brake and put the vehicle in Reverse (with foot still on brake) the vehicle starts reversing with force even though my foot is hard on the brakes. I then push down even harder on brakes. I am fighting to keep the Explorer from roaring out of the garage. Luckily I haven't hit anyone or anything, but had I not reacted as quickly I could easily have caused serious injury. I reported this problem to my local dealer two times, the first about 10 months ago and the second incident was reported to the dealer when I took it in in August 2021 for numerous alerts received in July 2021 for: POWERTRAIN MALFUNCTION/ REDUCED POWER; PRE-COLLISION ASSIST NOT AVAILABLE; HILL START ASSIST WARNING, PRE-COLLISION ASSIST NOT AVAILABLE. The dealer said all the alerts came from one power module which will be fixed this week when the part arrives at the dealer. The dealer also said that the recent Reverse power surge I advised them of is probably related to all of the alerts listed above and that this should take care of the problem. I never received any warnings, messages or other symptoms of this problem - it has always been a shock when it happens.

Vehicle would not start and every warning lamp and alert triggered on the dashboard. Tried remote start which was successful, but vehicle shut off 5 seconds later and the above alerts/warning lamps repeated. Vehicle would not start and just repeated all of the warning lamps/alerts. Waited 20 minutes, car started without issue; however, when put into reverse WITH FOOT ON THE BRAKE the vehicle started to drive backwards WHILE FOOT WAS STILL ON THE BRAKE! No amount of pressure on the brake pedal stopped the vehicle. Had to depress and repress the pedal to stop the vehicle. Rear cameras failed to activate as well. Luckily no one was injured. This is the third time this has happened, the third time I have reported to the NHTSA, and the third time I have reported it to my local dealership without resolve.

There are times when I start the vehicle, or manually release the parking brake, that it simply does not release. The brake pedal becomes rock hard at these times, without its normal travel. If the vehicle is reversing, like leaving my garage, it stops like it hit a brick wall when the brake pedal is touched. The rear brakes are simply locked. It stops so abruptly that it has aggravated lower back pain from previous injuries. I-€™m afraid of getting stranded in traffic, unable to move the vehicle. It did this on dirt and it was just dragging the rear tires. The only solution I have found is to turn off the engine, wait a few seconds, restart the vehicle, hope. I got, in rapid succession: 1. ANTILOCK BRAKE FAULT !!! 2. HILL DESCENT CONTROL FAULT 3. PRE-COLLISION ASSIST NOT AVAILABLE 4. HILL START ASSIST WARNING The service at Mesquite (Nevada) Ford was totally insufficient. I expected them to find and fix the problem, which obviously lies in the anti-lock/parking brake. I was eager to get the vehicle back and find out what was wrong as I-€™ve been afraid to use the manual parking brake for fear it will seize up and not release. When I got the vehicle back (which took a long time and a long story as the mechanic went home sick in the middle of the job with COVID) they said, -€œOh, we reset the error message so everything is fine.-€ Well, it still locks up, sometimes when I have shut the engine off and sometimes when I tried to manually set the parking brake, which I am still avoiding. If it-€™s only my vehicle then there is a dealer problem. If there are more reports, then it-€™s a bigger problem. I don-€™t know where on your site to say this -€" I am shocked by the number of fatalities -€" but not really. Either reduce the speed limits in the west or keep killing people. 80 mph is ridiculous because everyone now runs 90+ mph. We-€™ve come upon two fatal accidents this summer on I-15. The carnage was terrible. Please, please, please slow the traffic.

Same failure as other drivers have reported. Very occasionally, immediately after engaging drive/reverse from a fresh start, parked position, brakes do not work correctly. Very hard wall on break press with very little to no breaking as a result. Vehicle continues to slowly roll in selected direction regardless of break pedal pressure until holding the break and transferring back into park. No error is displayed during this event. So far, 100% of the time, transferring the vehicle back into drive/reverse after having experienced this issue, it does not immediately reproduce. Issue has occurred 3 times in 17,000 miles.

When shifting into drive, vehicle will randomly have a hard brake pedal and vehicle will lurch forward with increased RPM. Use of E-brake or putting transmission in park required to stop movement. Place trans in park and restart of engine and problem gone until next time. Use of reverse, vehicle will suddenly stop and sound as if you hit something. Brake pedal very hard. Have to place trans in park and restart engine. The issue occurs from a stationary condition, in driveway or public parking areas, so this causes concern that this may ultimately result in accident or collision with a structure, another vehicle, or a pedestrian! issue cannot be repeated on demand. It is entirely random and every drive has to be approached with the expectancy that the vehicle will move without normal brakes to stop. There are no alerts to tell us why (or which system) is the issue. This has occurred randomly since buying this Explorer St. Ford service seems surprised and unaware of this issue (and more).

I was backing out of a parking space and I tapped the brake. The car kept going backwards so I pressed it harder. It felt like the brake became concrete and would not go down any further. I pressed harder and it finally went down. I did not receive any error messages.

The most recent and severe incident occurred February 27 2021. I've started my 2020 Ford Explorer St via remote and entered it to move it in order to load the vehicle. The loading the vehicle all in all took about 15 minutes, the whole time, it was idling. I've put the vehicle in reverse, backed out of a spot and started driving forward in the lot I was in at about 10mph. I've attempted to stop the vehicle, but then it was not slowing down properly. I had to use the E-brake button to stop it. It came to an immediate stop. The dash was cycling through numerous warnings; 1. hill descent control fault 2. anti lock brake fault 3. pre collision assist not available 4. hill start assist warning 5. hill descent control fault 6. service advance track system 7. check brake system 8. park brake fault service now I tried testing the brakes, while going forward and backwards, the were weak and inconsistent. Like they were pulsing with full power and then nothing. Restarting the vehicle made all those warnings disappear. Took it to the dealership, which is the 2nd time that is it going in for brake and power train related issues. Few times a months since I've bought it, the only issue I would have, is on startup and immediate movement, the brakes would sometimes bottom out and not be able to stop the vehicle when in gear unless I put it in neutral or pump the brakes. Was told that they do not see any codes, and might be just a weird timing with my start ups. The most recent event on the 27th, was what prompted me to report this. Vehicle was idling for a while and moving with weak or no brakes to stop. That could have resulted in an incident.

I received my 2020 Ford Explorer back from the dealership on 01/23/2021, after it had been at the dealership since 12/22/2020 for an "overheating" issue, which turned out to be a module and sensor issue. While driving last night I received a warning for a "powertrain malfunction". I was able to get home with no issue by driving slowly. I parked the car overnight and checked the status this morning, 01/24/2021, in order to call roadside assistance and let them know what the current issue is. When I started the car I received warnings for "pre-collision assist" not available, "hill descent control" fault, "hill start assist" warning, and "anti-lock brake" fault. I attempted to move the vehicle in my driveway to make it easier to load on a tow truck, and I had almost no braking power. I had to put the vehicle in park to stop it from rolling down my driveway. This will be the third time in a month that the vehicle has to be towed to the dealership for a major issue that has left me stranded. This vehicle has 7,393 miles and was purchased 04/2020.

I was stopped in a parking space with the car running. I put the car in reverse to leave and noticed a car coming so I pushed on the brakes to stop, however the brakes did not engage. I pushed all the way to the floor and the car kept rolling. There was no resistance to the brakes, they felt loose with no resistance. I checked my feet to make sure I was actually pressing the brake and I was. The car was not stopping, and another car was coming behind me, so in order to finally stop I had to put the car into park. I waited a minute and then tried to put the car into drive and the brakes worked. I then put the car in reverse again and the brakes were working. About 30 minutes later I was attempting to turn the car on after leaving a store, and when I pressed the brake and then pushed the start button I received an error message that said to press the brake to start the car. However I was pressing the brake. I took my foot off the brake and then tried again and the car started. So this was a second time in the span of an hour that the car did not recognize the brake was pressed. The car was taken the very next day to the dealership however they did not see a code that had been thrown and they have been unable to replicate the issue.

The vehicle has a 'wake up' noise unlike any other that Ford can show me. Once you open the drivers door, it make an extremely loud metal grinding noise under the hood in the ABS area. After you drive the vehicle and park it, it does it by itself 30 mins later then again once you open up the door again. Also, the break pedal and breaks lock in place at times when going from park to drive or reverse. Not immediately, but once you start to move causing the vehicle to violently jerk. The 'crash warning' for a vehicle stopping short in front of you also goes off by itself without anything at all in front of you causing the alarm to sound and the vehicle to break on its on. This happens a various speeds but especially on the highway. All of these issues have been happening since I purchased the vehicle brand new in may of 2020

The first issue was with the car accelerating without pressing the gas. Rpms would increase and car would sound as if it was accelerating as well, when slowing driving through a parking garage. The car also down shifts and accelerates roughly. It is not smooth when transitioning to acceleration or de acceleration. When braking the car jerks until stopped enough to where our heads jerk. Putting car into gear, to drive from reverse, it lags until it kicks in and jerks hard. When shifting into reverse with the foot firmly on the brake, the vehicle begins to roll backward with my foot still on the brake. When you try to press the brake pedal to get car to stop moving, brake pedal does not depress all the way and does not stop the vehicle from moving. If you attempt to pump the brakes, there is a hard stop that prevents the brake pedal from going all the way to the floor. The only way to stop the vehicle is to put it back into park.

Drivers seat appeared to shift when turning. This has resulted in the plastic trim at bottom of seat to break and come loose from seat while moving. This has occured twice. Additionally we have received error messages on the 4WD while on an extended trip. It dropped us out of cruise controlled an told us to service transmission. Also reverse assist was inactivated as well as cruise. Back up view on screen turned blue. Brakes have also become inactive when starting to back up. (November 15, 2020) these problems are continuing to occur and the dealer has not tried to fix the issue.

- Chapin, SC, USA

When put into gear, brakes would not apply had to press extremely hard both in reverse and forward. Had to put vehicle back in park and turn off. Let reset, turn back on, and brakes started to work normal. Back up camera went to blank blue screen also.

2020 Ford Explorer St with approximately 5,200 miles. Yesterday, I started the vehicle and put it into reverse and it started to roll backwards even though my foot was on the brake. Regardless of how hard I pushed the brake, the car continued to lunge backward until I fully depressed/repressed the brake. With my foot on the brake the vehicle continued to move. This same event occurred a few months ago but when in drive and the vehicle continued to lunge forward despite my foot full pressing the brake as much as possible. I shut off the vehicle, waited a few minutes, and attempted to restart. Restarted without issue. Today, I attempted to start the car and all lights on the dashboard began flashing and the engine failed to turnover. The in-dash display then began beeping, flashing all service/hazard/warning indicators, and cycling through the following error messages: - steering assist fault service required; - see manual (with wrench icon indicating powertrain fault); - front camera fault service required; - service advancetrac; - full accessory power active; - park brake fault service now; - pre-collision assist not available; - check park aid; - reverse brake assist not available see manual; - hill descent control fault; - normal cruise active adaptive braking off; I turned off the vehicle and attempted a few more restarts ranging in intervals from an immediate start/stop, 1 minute, 5 minutes, and 10 minutes without success (same error messages displayed as described above). My next attempt was a few hours later and the vehicle started without error, but did not give any indication that the vehicle had failed to start the previous time and the 'powertrain fault' wrench icon remained lit.
