While driving with my [XXX] son in the vehicle, the vehicle suddenly shut down completely in the middle of the street at a red light. Nothing was functional and we were unable to move the vehicle out of the street. A tow truck came in 3 hours and towed the vehicle to the dealership. The dealership advised that it was the battery which they replaced. When merging lanes on the interstate with oncoming traffic, the gas accelerator would not accelerate to speed up. I had to step all the way down on it several times until the vehicle was finally able to accelerate. This has also occurred while at a red light and stop sign.

2021 Ford Bronco Sport brakes complaints
Page 2 of 5: complaints 11 to 40 of 128, newest first, as owners wrote them.
While driving, the brake pedal suddenly required extreme pressure to stop the vehicle safely. I pulled over and parked in a parking lot. Upon opening the hood, I heard a hissing sound. During inspection, I found that the brake booster vacuum hose had broken at the check valve connection near the brake fluid reservoir. A temporary fix restored brake assistance. With the resulting significant loss of brake assist, I was forced to apply near full body weight on the brake pedal to slow and stop the vehicle. This could have easily resulted in a serious crash if traffic conditions were different. The issue has not yet been inspected by a dealer or any others, but the vehicle and the failed component are available for inspection upon request. No warning signs, symptoms, or lights were experienced or observed before the hose failure.
Upon starting the vehicle, brakes were extremely hard to press down and barely responded. A great deal of effort was needed to bring the car to a stop at below 5 miles an hour. If I had been driving instead of pulling out of a parking lot, this could have caused a significant accident.
Brake Valve Failure while driving
The brakes make a loud and terrible squeeking noise (moan noise) when driving the vehicle in reverse and braking. There is something terribly wrong and may initiate a problem at a later date when driving forward. Ford is aware of the problem and issued TSB22-2326 in August 2022, revised to 23-2041 in February 2023, revised to 23-2308 in October 2023 and revised again to 25-2143 in April 2025. THEY HAVE SUCCESSFULLY DELAYED THE RECALL FOR THREE YEARS NOW THAT ALL 2021 BRONCO SPORTS ARE OUT OF WARRANTY. This is rediculous and dangerous.
The contact owns a 2021 Ford Bronco Sport. The contact stated that upon reversing the vehicle and depressing the brake pedal, there was an abnormal vibration sound coming from the brakes. There was no warning light illuminated. The vehicle was taken to a local dealer to be diagnosed, and the contact was informed that the rear brake parts were faulty and needed to be cleaned and replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 46,000.
I was driving 70mph on [XXX] in New Jersey when all of a sudden with no prior warning the battery light came on and my vehicle became very hard to control, I felt it shutting down so I immediately pulled to the only shoulder which happened to be on the left. The car shut down and would not start again. A State Trooper said I can not stay on the left shoulder and decided to push my car to the next exit. Since it was an electrical problem my car kept locking up and would not stay in neutral and the steering kept locking as well. I was being pushed on the left shoulder with car speeding past me while my car was locking up which also cause my tires to blow out, I was afraid for my life but the officer continued to push me. This is the second time my vehicle shut down on me leaving me in a dangerous situation, I'm afraid that next time it happens It could cause me to get seriously injured or my life! I had to have it towed to the dealership and I was charged almost $1000 for repairs and 2 weeks later I received a recall letter on this issue for the software.

When reversing the vehicle, the rear breaks will make a whale sound I have video
When I bought my vehicle in 2021. The brakes makes a squeaky noise when backing up. I took to dealer and the mechanic said it was normal his wife have the same car and her Bronco does the same thing. The brakes still makes noise when backing up and it’s year 2025. I’m thinking about going to another brake pad but buying a new vehicle for it to squeak is not right.
Like the other people state. Rear brakes make a moaning noise when backing up. First thing in the morning when trying to back the vehicle out of the garage. I put it in reverse, and it holds like the brakes are sticking. You have to hit the throttle to make the care move and you hear a pop noise like the brakes released. My garage is not on a incline or any kind of slope. We took the car to the dealer and they stated Ford knows about it but there is no fix. You need new brakes and rotors that cost over $800. If Ford knows about it why do I have to pay when they know it's a problem?
I was unaware of any previous recalls before I purchased my Bronco Sport used. There is an active recall that has no remedy for the battery. I am actively having issues with my fuel system. It was inspected more than once. Diagnostics returned zero issues 3 times and no warning lights. I insisted further inspection this time which revealed bad purge valve, charcoal canister full of fuel, coolant leak resulting in water pump replacement needed. No warning lights. No codes, active or stored. Due to the absence of codes, they will not replace my fuel injectors per customer satisfaction program 22N18. Was not ever informed that recalls 22S73, 22S21, and 21C31 were either inspected or completed on my vehicle as it was not ever disclosed to me and the Ford website only state "scheduled maintenance" was performed. I still cannot obtain documentation of those previous service records so that I may be informed on what could have led to the current issues I am having with this vehicle. I have 3 kids I drive around and do not feel safe putting them in it anymore due to official documents issued by Ford that state my car could either lose power in the middle of driving it, or catch on fire due to a cracked fuel injector.
The contact owns a 2021 Ford Bronco Sport. The contact stated that while the vehicle was in reverse(R), there was an abnormal screeching sound coming from the rear brakes while depressing the brake pedal. There was no warning light illuminated. The contact had taken the vehicle to a local dealer and an undisclosed recall repair was performed; however, upon retrieving the vehicle, the failure worsened. The dealer was notified of the failure but offered no additional assistance. The manufacturer was notified of the failure and referred the contact to the NTHSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was unknown.
Rear brakes are noisy, they make a grinding noise. Ever since we got the vehicle . Screens turn black while driving , can control infotainment system Water gets into the vehicle when it rains or when getting car washed
The vehicle has been in the shop since day one with many many problems! The TURBO failed under warranty so they replaced it without doing proper procedures. A few months later the turbo failed again out of warranty but this time cracked the head causing damages I can not afford!! The vehicle is sitting at the dealership not fixed!! I want out of this lemon!!! I tried getting them to buy it back when I took it to the shop three different times due to break issues they could not fix but a Ford representative told me it "had too many miles" I work out of this vehicle and have not been able to work now for three months!! Note...after the first TURBO was replaced I told the dealership the vehicle was loosing antifreeze but all they did was pressure check the radiator. A few months later engine failure due to turbo failure!!
Breaks squeal while in reverse.
While in reverse when you press on the breaks they squeal.
My 2021 Bronco Sport suddenly died on [XXX]. The parking brake engaged unexpectedly, locking all four brakes and resulting in a significant skid mark. An error message flashed: “Park Not Available. Apply Park Brake Before Exiting,” and the park gear light blinked. I turned off the engine again, but the car was dead when I tried to restart it. After getting a jump start, the car turned on. However, the parking brake engaged again shortly after. I was able to drive it off the road. My wife, a research librarian, found that many others have reported issues related to “Sudden Death Syndrome." See below. [XXX] [XXX] ). The car was towed from PA, where we were visiting, to Stanford Ford, where we purchased it on [XXX]. On 11/13, the dealership told us there was a short circuit in the wiring connected to the solenoid and estimated $900.00 for labor. At noon on 11/15, the technician was test-driving the car. By 4:17 PM, I was told it was ready. 5 min. later, they told me it wasn't ready due to another issue. At 11:15am on 11/18, we were informed the issue was a short circuit in the transmission, costing $13,000. How is that possible? The car is only three years old! We've faced many recalls with this car, the last just this past August, but the most dangerous issue is the unexpected engagement of the parking brakes, causing chaotic behavior. Given the number of similar incidents, it's hard to believe there hasn't been a recall. We could have been injured or even killed if we had been driving over 40 mh and driving in heavy traffic, or worse, on the highway.

Brakes Made loud squeaks noise when in reverse. Have taken into dealer multiple times and not fixed. They say an issue with Bronco Sports but my vin does not show on recall. Worried about brake failures or issues that could arise. They replaced front rotors and deglazed pads. Spent 462.19 and problem never fixed.

When I back out of driveway or any parking space, the brakes make a loud moaning noise along with what is almost a grinding noise. It does not matter the time of day, the temperature, or humidity. The car makes the noise every time it is used. This has been an ongoing issue since owning the car in 2021, and it has been to the dealership on three occasions to have the issue looked at. The brakes and brake pads look good and nothing else is visibly wrong. This has been an ongoing issue since shortly after purchase in 2021.

Since the purchase of the Bronco Sport in 2021, I have intermittently taken it in for required service. However, there have been times when I have had to take it in for hearing noise coming from when I make turns, and it sounded like my break pads were making the sound of wear. A recent report did address the break pad concern, and they were replaced. Intuitively something told me to check my fluid levels and the engine air filter, along with the cabin air filter. They both needed replacing, which I did on my own. The mechanic who put on my break asked me questions about the Bronco, I explained to him that I was having issues with take off, and have had to take it in for recalls since make the purchase. He asked me to open the hood. What he found was oil leaking around was oil leaking around my turbo. I was shocked. Because it had not been long since it was serviced. I was told to not drive it too far because there were reports of some Broncos catching on fire. When I would take it in to Town AND Country Ford, where it was purchased, they would tell me that they could not find anything wrong repeatedly, supposedly one of the recalls was fixed. Yet, I still hear the noise when I make turns. Another Ford dealership around the corner from where I live and I decided to take it there to see if I could get different results. No help. They have changed my oil I hope. Then there is Bates Ford in Lebanon, Tennessee. I have taken it there for oil change and informed them of issues. This is the last dealership who inspected the Bronco. They did not tell me about the oil leak. I drive 10 miles to work weekly. 100 miles every other month to visit elderly relatives. So, I have not put too much wear and tear on the Bronco and do not drive it hard. Please, If you are able to help in this area, it is much appreciated. I have 54,000 miles on it
The vehicle was traveling on a major highway when at a red light the car stopped and the auto start/stop engaged and the car turned off. After the car turned off I could not restart it. All power to the car was lost. No lights, radio, nothing. I attempted to put the car in neutral to move it off the highway, however the car is designed in a way it can not simply just be shifted into neutral. I grabbed the owners manual and read I needed to pull the manual park release cable located under the steering wheel. I pull the cable nothing. At this point I’ve called the local police department and they send out 2 officers. They attempt to shift the car into neutral as well, to no luck. I read the electronic parking break needs to be turned off but the car needs power to do this. My car has no power. A man comes with a jumper box and attempts to jump the car when it starts smoking. The battery has full voltage however it’s not transferring power to the car. I have to sit in the middle of a highway for 2 hours until a tow truck can tow my car. In those 2 hours I was at a significant risk of bodily and property damage and also risking harm to the other drivers on the road. Ford has no suggestion how to fix my specific problem. They’ve not taken into account a situation where there is no power to turn off the electronic parking break, to pull the cable and shift the car into neutral. The Ford service department had no idea how to replicate the situation to try and fix it. All I asked Ford for was a way to safely be able to remove my car from the middle of traffic the next time it happens. They have told me they can not help me. The Delaware city police department sent two officers who witnessed the event. Prior to the loss of power there was no warning. $1000 later I had a new starter put in and Ford did some recall work on it. However in my opinion the car is unsafe in the event power is lost again on the road.
When in reverse the rear breaks give off a loud squealing noise. This vehicle has been brought back to the dealership 4 times so far with no solutions we just are told that’s what these vehicles do. Completely unacceptable for ford or any repair shop to say basically it is what it is. There is obviously a defect somewhere within the breaking system/products that ford used. Breaks should not be squealing like that and we shouldn’t have to be responsible to pay for new rear brakes, rotors, pistons and calipers to “see” if that fixes the problem. There are numerous complaints about the same issue and ford doesn’t seem to care and they continue to put out subpar vehicles.
I was exiting a store parking lot when my vehicle died and I lost the steering, hazard lights, ability to put it in neutral. It wouldn’t start, but the radio and air conditioning still was on. When I attempted to start everything would blink.
Vacuum Booster Line Detached (Broke Off) from the Vacuum booster Unit. This happened when I was pulling out onto the road and noticed brake became stiff. Could not get vehicle to stop without forceful pressing of brake. Fortunately I was not in traffic but did have cars behind which had to slow to wait for me to pull over. I could have been rear ended. There was no warning or symptoms of this failure. Dealership had it towed and replaced the vacuum line.The service advisor said this was the first he's seen this in the line of Broncos. I have seen several of the same stories on Bronco Forums. This is a known problem. At barely 40K this should not happen and should be part of the Power Train. I had to pay nearly $450 for the diagnostic, part and repair as it is out of warranty
I was backing out of a parking lot of my employment on the early evening of 8.22.24. I heard the familiar whale moaing noise coming from the rear brakes ( has been in and out of the Ford Shop for to address this know issue; still no permanent solution), I immediately noticed when I went to touch the brake pedal it would not push down. The pedal was stiff and required me to heavily push down to get the vehicle to stop. I noticed a severe grinding noise. Fortunately I was able to turn my car back around and safely park it. I pushed the parking brake button and it was not on and then it would not go off. It finally did after several minutes. A friend who knows cars went back with me to look at what could possibly be wrong. He looked under the hood and found a broken vacuum line. I have pictures. I left the vehicle and went home to research. I found a 2021 Compliance Recall Notice 21C31/the federal safety agency Recall 21V922. I purchased this Bronco Sport used in the fall of 2022 and do not recall knowing of any recalls, including if this specific one was performed on my vehicle . This recall correlates to what happened to my vehicle. It looks like the vacuum booster failed, wore out and caused my automatic brakes to fail. There was no warning lights or indicators that anything was faulty up until the incident. The vehicle has had regular maintenance and has been in to Ford Service to address the most current recalls and TSB's issued since I've had possession. This shook me up . I am so lucky I was not driving at a high speed and in traffic. Things could have been a lot worse. I am deeply concerned about this vehicles safety profile. There seems to be a pattern with this make a model concerning various components including the brakes. I this point I need it fixed so I can look at trading it in for a reliable and safe alternative. I am attaching pictures as well and the recall notice that I found a a Ford Forum from an owner who received this back when the issue originated.
On days when it rains or the weather is slightly cold/dewy, the Ford Bronco seems to make a screech/horn-like sound only when reversing. I found some online forum links (listed below) where other Ford users seem to describe the similar issue we're experiencing. This is the second dealership that we have taken the vehicle to be serviced for the issue, but they have both stated there is nothing they can do because the issue has not been issued as a recall. [XXX] [XXX] [XXX] The first dealership visited for service was: Metro Ford Sales & Service, Inc. Address: 6455 S Western Ave, Chicago, IL 60636 The second dealership visited for service was: Napleton Ford of Oak Lawn Address: Address: 6100 W 95th St, Oak Lawn, IL 60453 The attachment includes the most recent appointment visit. Unfortunately, I cannot provide an invoice at this time because the vehicle is still at the dealership (10 days after taking it in). I visited the dealership yesterday (08/12/2024) where I was informed that the the service technician working on my car is in the hospital. Had I not visited, then I probably would not have known this, and the other service technician I spoke to said they could not share any more details since they were not part of the servicing for my car. Martin Garcia ([email protected]) is supposed to be the middle-man between me and the dealership to help me address the issue, but I have not received information from his end either. When I called the Ford's number using (866) 631-3788 to get a hold of Martin Garcia, someone else assisted and I was told that he would call me tomorrow (08/14/2024) to give him an update on what the dealership shared with me.
