2021 FORD BRONCO SPORT Engine Problems

I've had 3 water pumps replaced first one was right before 36,000 miles, 2 were after the bumper to bumper warranty. Had the rear drive unit replaced for grinding, that was at about 28k miles, torque converter was also replaced at about 35k miles, oil leak from my camshaft carrier gasket, thermostat housing split, battery replaced after a year. This vehicle has been nothing but issue after issue. Each time low coolant, no heat in the vehicle. No warning lamps, nothing to tell me it was low.

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...

The contact owns a 2021 Ford Bronco Sport. The contact stated that after refueling the vehicle, the vehicle failed to start up, with the check engine warning light illuminated. The vehicle was taken to the dealer where the fuel injector was replaced under warranty. The contact then stated that while driving at various speeds, the vehicle jolted forward upon depression of the accelerator pedal. There was no warning light illuminated. The vehicle was taken to the dealer where the contact was informed that the transmission, catalytic converter, and water pump needed to be replaced. The manufacturer was notified of the failure but offered no assistance. The vehicle had not been repaired. The failure mileage was approximately 55,000.

In 2021 i purchased a brand new Bronco Sport Big Bend with the hopes that it will last as long as the previous Bronco models. Unfortunately, 3 years later i took the vehicle to a Ford dealership, and to my surprise the transmission needs to be replaced. Being a vehicle that is regularly driven by my pregnant wife is an issue that Ford needs to be accountable for. There were no engine lights on, the only warning was a noise i noticed when driving the vehicle myself in the highway. I understand that transmission failed throughout the course of the years, but to a 3 year old Ford Bronco Sport is just ridiculous and not safe at all. The vehicle is currently at the dealership, Ford has agreed to pay 5k towards the replacement but i still have to come up with more than 7k to get it fix. If...

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.

On 1/23/24, car was serviced for an electrical fault with the fuel pump control module which was confirmed via a vehicle alert. On 6/12/24, car was serviced for a software update recall. (I believe this was in relation to the fuel injector issue.) On 7/4/24, the car would not start but kept clicking trying to start. White smoke started coming out from under the hood. Panicked, we called the fire department and my niece's husband disconnected the battery so that the car would quit trying to start in an effort to mitigate a full fire. We could smell burning and fuel. The fire department even confirmed something smelled like it had burned but there was no active fire, so they told us to leave the battery disconnected and have it towed. I had the car towed to the dealership for $249. (Of which Ford only reimbursed me $140) My car...

While driving on the highway at 65 mph the vehicle completely shut off. All electrical components stopped working as well. After the recall was “fixed” it still randomly will not turn on. This car is a horrifying death trap and should be recalled completely, this is incredibly unacceptable for use and terrifying to drive. I was lucky there were no other cars around me at the time.

I recently had the recalls addressed (despite having any issues with the vehicle). Days later, I noticed my vehicle would occasionally not detect my key fob. Changed battery without resolution. On 6/27/24, I was driving in rush hour traffic, and stopped with the red light. When the light turned green, I went to drive, and the car shut itself down. Everything shut down. Couldn't even turn on my hazards. While waiting for a tow truck, I received a tip to use the key fob to push the start button, and that actually worked. I took it to Ford, and they returned it 12 days later with updated modules (they stated they couldn't diagnose the issue which is fascinating to me considering the nature of the recalls and all the information I am able to find online). 10 days after having it back, the vehicle hesitated to start and displayed a...

My 2021 Ford Bronco Sport has had its water pump replaced twice. Most recently, in April 2024. In June of 2024, that water pump also failed. My Ford dealer then discovered "catastrophic" damage to the turbo and engine, including a possible cracked engine as the result of the vehicle overheating because of the lack of coolant circulation. This obvious defect in the Ford water pump resulted in a serious safety risk and potential for the engine to completely overheat and catch fire, threatening the occupants inside.

June 2024, I received mail for safety recall notice re: 24S24/NHTSA 24V267. July 16, 2024, went to ford to have it fixed. Ford said everything works good. [XXX] @1450, Me and my son [XXX] old) drove to freeway in [XXX] and my car just suddenly stopped. No electrical power at all. Even the hazard lights doesnt work. Need to call 911 for safety. I was in the middle of the freeway for about 15 mins. Speed limit in the freeway is 65 miles/hr. I was so scared because I have my son with me and anytime somebody might hit our car. I had to call towing and sent to the livermore ford dealership. (Thats where i bought my car). My bronco sport will be paid off this november 2024, now im scared driving in the freeway especially i drove 40 miles one way, going to my work. What if it...

Previous NHTSA ID Number. 11596944. Recall fix was run earlier this month. Car died at stoplight two days ago. Fix run again at dealership. Car died at red light again today. Was able to put car in park. Tried to restart. Multiple flashing warnings. Was able to get hazards on this time. Had car towed back to dealer. They are calling Ford. Second time this happened at busy intersection. This time at interstate on ramp. Bus driver attempting to turn got out of bud and offered to push the car but we could not get it in neutral. Tow driver had towed in a bronco sport right before us with the same issue. Someone is going to be seriously injured. Service guy showed me record of previous error messages. There were about twenty. I have a video of the screens flashing today.

Vehicle experienced complete shut down in the middle of the road while stopped at an intersection. Could not turn on hazard lights or put the car in neutral to move out of traffic. Car made a loud thumping noise when I attempted to restart. Vehicle was towed to dealership where I was initially told the battery just needed to be charged and it was ready to pick up. When I went to the dealership to retrieve my vehicle, it would not start and had the same error messages on screen and made the same loud thumping noise. Vehicle is currently still at the dealership and no answer as to when it will be fixed or what the issue is. Today is day 5 without my vehicle.

In March 0f 2024, while traveling down the highway at 65 mph, vehicle lost power suddenly, engine shut off, and loss of power steering with no warning, no check engine lights, no change in temperature to motor. Vehicle was towed to dealership in which they advised the engine was locked up and later determined the turbo had failed, likely leading to the engine failure. The 2021 Ford Bronco Sport only had 30,000 miles so it is apparent this motor and or turbo has some type of fault. Dealership did not cover under warranty as vehicle had branded title from front bumper damage that did not effect the engine.

I bought my Bronco back in January this year (2024) and everything worked great. Then fast forward the end of May (2024) and my car when I got in it and crunk it up told me my MyKey had been activated. I said what is a MyKey never heard of it before in my life. I did some Google searches and tried to figure out. Once I figured it and couldn't get it off of there myself I took it to a Ford dealership. They told me the MyKey had to have the admin key and they would have to cut one etc and then the labor all together would be 400 dollars. I was floored how did this even happen? Who put the MyKey on here? It restricts the speed which you can go, only allows the radio so high, and you have to be buckled for the radio...

On May 25, 2024 at about 12:30 am, The vehicle suffered a classic recall 24V267000 unexpected and sudden complete loss of engine and electrical power in traffic, going into default park setting with parking brake. The vehicle could not be pushed out of traffic on a busy expressway feeder road at night. Police had to be dispatched to warn oncoming traffic of the stalled vehicle with intermittently working hazard lights. The vehicle had to be towed. Sames Ford McAllen preformed the recall reprogramming on May 31 and released to vehicle. On the first trip AFTER the BCM and PCM recall protocol had been performed the vehicle suffered the exact same failure in traffic on a busy street. The vehicle again was towed to Sames Ford, where it remains today. The recall protocol failed to remedy to serious and dangerous defect.

The contact owns a 2021 Ford Bronco Sport. The contact stated while in reverse(R), there was an abnormally loud sound coming from the rear of the vehicle. The vehicle was taken to the local dealer on several occasions. The contact stated that unknown repairs were performed on the vehicle, but the vehicle was not repaired. The local dealer was unable to determine the cause of the failure. The contact stated that the vehicle remained unrepaired until further repair information was provided. The manufacturer was made aware of the failure. The failure mileage was approximately 9,000.

While idling stopped at a red light the engine suddenly shut down/stalled and the electrical system simultaneously went haywire. Specifically the dashboard alert system rapidly cycled through/flashed warning alerts for the forward collision system, then “out of fuel” then a failure with the antilock brake system. At the same time the computer touch screen went black and indicated “system restart.” The dash alerts kept cycling through the same alerts mentioned above and wouldn’t stop. I tried three different times to restart the vehicle without success. Stranded on a busy roadway, two different vehicles behind us had to take evasive action to avoid hitting us from the rear. The vehicle was towed to the dealer, who has called back to say the engine starts fine now. They will conduct further diagnosis.

I was driving and the car turned off while driving without warning. Luckily I was not in an area of high traffic but if I had been then it would have caused a serious crash. Car would not start again even after being jumped. Had to have towed. Ford told me there were no recalls related to this incident when I called customer service today only to find online other owners have had serious issues similar to this as well.

On Saturday, [XXX], my 2021 Ford Bronco Sport with approx. 33,900 miles completely shutdown and lost all power to engine and accessories while driving the vehicle in traffic. It started making a ticking sound that could not be stopped, it could not be restarted, and no accessories to include hazard lights could be turned on. I had to call the police, as my daughter and I were in the middle of traffic and cars were honking at us and I could not move the vehicle nor signal that it had died. The police arrived and since I was blocking traffic they are required to initiate a tow (which I had to pay $150 for), since they will not risk waiting hours for individual roadside assistance to arrive. The car has been towed to Ourisman Ford in Alexandria, VA, where it still presently remains as their only solution was to recommend...

My son and I slowed at a light to turn right. The vehicle completely shut down in traffic. We couldn’t put the car in neutral. We couldn’t turn the hazard lights on and couldn’t jump the vehicle. Luckily we were going slow traveling approx 10-15mph. Our emergency jump machine eventually worked after about 10 minutes, but the console screen remained blank and we drove straight to the dealer, but on Saturdays they don’t have any actual maintenance. The only thing they said they can do is test the battery. After a search on the internet, this has happened to lots of people. Some 2021 Ford Bronco Sports have been recalled, but mine isn’t listed. My question to Ford is, if this is a known issue why are they risking people’s lives? Again luckily we weren’t on the highway or even busier traffic.

I had driven for about 30 minutes, without turning the car off, I had just picked my fiancé up at the train and was slowing down for a stop sign. The car just stopped completely the lights flashed and powered down and I couldn’t do anything with the drive shift or even get the flashers on. Luckily we were coming to a stop anyway, but for majority of the time I was without flashers lights or anything and it was getting dark. We are in Virginia working and are usually traveling the interstate at the time but happened to do separate modes. I don’t know what could have happened had I been going 70 on the highway at night. I keep trying to start the car and was eventually able to put it in park but wasn’t able to get it into neutral or anything else. After multiple start attempts...

As I was driving with my wife on our way back home, my vehicle flashed every warning light, and my dashboard went dark. I was going about 40–45 mph, the engine was still running, and we made it home, which was only less than 2 miles from my house. As I was driving on my way home, the media console had this message: "vehicle network communication error," but once home, I could not get the SUV to shift into park, and it suddenly shut off on it's own. My 2021 Bronco Sport is still under Ford's manufacturer warranty. I requested a tow from the Ford app to have it delivered to Hacienda Ford Service of Edinburg, Texas, and a payment of $201.09 was required to dispatch a tow service. A couple of days later, I got a call that my SUV was ready, the battery might of been in a...

It shakes, rattles and sound like a ship yard while backing up

On February 5, 2024, the engine of a Bronco Sport shut off while driving and the dashboard lights began flashing with multiple warnings and notifications. The car would not restart and the gear shift was locked, preventing the driver from moving the vehicle out of the road during rush hour traffic. A tow truck was called, but after 30 minutes, the driver was able to restart the car and canceled the tow truck. The car was taken to the dealership on February 6, 2024, but the cause of the incident has not been diagnosed. On February 4, 2024, the driver attempted to start the engine, but the dashboard lights began flashing with multiple warnings and notifications and the engine would not start. The driver called a tow service, who jump-started the battery and informed the driver that the battery was not completely dead. The driver also discovered that the power...

[XXX] Vehicle would not start(not even crank) while parked in the garage. Could not jump start, had to be dragged out of garage(could not put in neutral) and hauled on rollback to Blaise Alexander Ford Lewisburg, Pa. Dealership kept for 4 days and charged battery and could not replicate the problem. [XXX] Vehicle while driving message of Vehicle Connection Error came up on screen and then all gauges blacked out, turned off of road and died, could not restart, could not jump start and would not crank.

Slowing down at a red light, getting into a left hand turning lane there was a "thud" sound and then the car completely shut off. Nothing worked, screens went blank, no hazards, no lights. We were stuck in the middle of the road with no way to even get the car out of the way. Every once in a while the green would come on or an alarm would go off but quickly went back to black. Tow truck was able to jump it to get it on the truck but half way through the ride the engine died once more. There was no warning at all. If this would have happened on the highway, it would have been catastrophic. After learning about this happening to others and hearing that it may happen again, I will not feel safe in this car moving forward: car is a 2021 Bronco Sport,...

Vehicle experienced catastrophic power failure while I was driving. Without warning, the vehicle shut down completely. The engine stopped, the brakes engaged, the dash went black. There was no way to communicate with the vehicle -- no way to engage emergency flashers or even to push it to the side of the road (because the brakes were locked). There was a loud "pulse" sound coming through the speakers -- "thump. . .thump. . .thump. . ." which continued for 5 - 10 minutes. A police officer who stopped to assist noted the rear tail lights were strobing. The "P" on the transmission shifter flashed continually. Over the next 30 minutes, the infotainment screen rebooted twice, but went to black within seconds. The instrument panel rebooted once, but also went black after a few seconds. The car was towed to Kings Ford in Mason/Deerfield Township OH. The service tech reported the...

Car stopped while driving. Couldn’t get the car into neutral to move it out of the road. Would not crank. Leaking oil.

Vehicle started missing at 30-40mph. No lights were on but I took it to the dealership and they determined a new transmission was needed at a cost of $6464.33 plus tax. They indicated it was a known issue but no recall had been issued so I was responsible for the cost. I checked around at other transmission shops and they also said they had been seeing those issues. I looked online and online forums don’t even recommend OEM parts because they will fail.

I was on my way to work and as I approached a 4-way intersection, the auto-stop feature on the vehicle shut the engine off. The vehicle's instrument panel started blinking then went completely black. The vehicle became completely disabled... the hazard lights were only functioning intermittently. I tried to re-start the vehicle without success and was not able to shift to neutral. The vehicle was in the middle of the road, so I called a tow to carry it to the dealership. The dealership was able to replicate the issue and blamed it on a 'dead-cell' battery. The dealership even said that the vehicle did the same thing to them once their booster pack was removed, so a simple jump from another vehicle would not have temporarily solved the issue. Before the incident, the vehicle gave absolutely NO warning or indication that the battery levels were low. I cannot believe...

Engine alternator failed at approximately 50,000 miles. The bearing failed and the pulley ultimately sheared off. We own 5 of these vehicles and 3 of the 5 have had this issue. The water pump also failed.

My 2021 Bronco failed our family on Friday. The Bronco failed to start upon pressing the start and brake pedal. The main console panel started flashing then cycling through all kinds of failure alerts. There was a series loud noises from the engine, the headlights flashed off and on for over 3 minutes and then the engine started smoking. The doors would not open and we were stuck inside while the engine was smoking. That smoke came through the air vents as well. Finally, I was able to get my door open though couldn’t open my son’s rear passenger side door from the outside. He was stuck inside for what seemed like forever. He was able to open it finally and I carried him inside. My son’s legs are paralyzed and he does not walk. My main concern was getting him to a safe place as I was scared to...

Stopped at Red Light on Southbound Groesbeck Hwy & Martin Rd in Warren, MI and engine and all dash lights went out without warning and could not restart car. Was stuck in middle lane of 50 mph traffic with car stuck in gear and no way to push out of traffic. Very dangerous position to be in. Had to call a local tow truck flatbed to puts skids under all four tires to load on flatbed to move car to Crest Ford dealership at a cost of $140.00

Bought 2021 bronco sport in Dec 21. Since my engine has stuttered and started to die. The panel starts falling as if it is sitting off. This is not the auto engine shut off while idling at a light issue. Upon starting the engine you can hear a ticking and on every certain revelation the vehicle will sputter and start to cut off. It has died on 2 occasions in my driveway, but not yet on the road. It will stutter and start to die almost always in idle, especially in park, but it will do it and stay losing power mainly while driving low speeds or when not pressing gas pedal. I received recall and was told part was not available and didn't know when it would be available and have never been told part was available, but miraculously my recall order was closed without parts ever being replaced....

There is an oil leak in a new car?!

When trying to start the vehicle, it would not crank. Instead, all dash indicator lights, interior lights, and exterior lights began flashing. Numerous random error messages began flashing on the dashboard screen. Then a large plume of smoke began coming out from under the hood and there was an acrid burning smell. No flames were visible so the fire department would not respond when called and advised to have it towed. After much difficulty loading onto a tow truck (the parking brake would not disengage--dash indicated a parking brake fault as one of the many errors--so it had to be dragged onto the flatbed tow truck) the vehicle was towed to the local dealership in Dothan, AL. Per the dealership, there was an underhood fire involving the starter and battery. We are unable to inspect the damaged components. They stated they are unable to remedy the smoke smell that has...

The contact owns a 2021 Ford Bronco Sport. The contact stated while at a stop light, the vehicle shut off with several unknown warning lights illuminated. The message "Service Collision Assist" and "System Powering Down" were displayed. After the engine cooled down, the contact was able to restart the vehicle. The vehicle was taken to the dealer who was unable to find a cause for the failure. The contact stated that the failure had reoccurred. The vehicle was not repaired. On another occasion while driving 15 MPH and slowing down, the vehicle lost motive power with several unknown warning lights illuminated. The contact attempted several times to restart the vehicle, but the vehicle would not restart. The contact was able to push the vehicle off the roadway and had the vehicle towed to the dealer. The vehicle was not diagnosed. The manufacturer was contacted and referred the contact to the...

Transmission locked in park while attempting to move off of a traffic light. Brakes locked up, unable to start car. Was stuck in the middle lane on a busy street.

I currently am at 14,000 miles on my2021 Bronco Sport. I have had no issues prior to what happened to me on August 9th. While I was at a light my car went completely black with no warning and I was not able to put on hazard lights or put it in neutral to get off the busy highway. I had to call 911 as cars were zipping up close to mine and I was only able to wave my arms to get them to see my car was unoccupied. I was screamed at, honked at all while frantic trying to explain to the 911 operator that I needed a deputy to come and put his lights on behind my car to prevent an accident. My car sat in the middle of the highway with no warning lights on until a tow truck arrived. We then found out there is...

On 2 occasions, 7/30/23 and 8/13/23, my 2021 Bronco suddenly stopped working with no warning whatsoever. I had no way to put on any Emergency Flashers because there was no power. The same day as the first incident, the car was brought to my local Ford Dealer and they couldn't find any problem. When they inspected it the next morning, it started right up.I had been driving the car for 2 weeks and it happened while I was driving again on 8/13/23. It died the exact same way, with no warning and no way for me to alert other drivers around me. My vehicle is currently at the Ford Service Department and they are trying to find the problem.

The contact owns a 2021 Ford Bronco Sport. The contact stated while driving at an undisclosed speed, the contact stopped at the stop light. When the light turned green, the contact depressed the accelerator pedal, and the vehicle lost motive power and stalled. There was no warning light illuminated. The vehicle was towed to the dealer; however, the vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

I was driving down a city street in Sacramento and the car just suddenly stopped- engine and everything was off. I could not get the car to turn back on. Emergency lights would not come on, it was if the entire electrical system was out. I was in the middle of the road, so needed to put hazards on to warn others and I could not. Cops came to place flares to warn other drivers after 35 minutes. No warning codes or anything to let me know what was happening. Having car towed. 10 minutes before tow truck arrived, vehicle started, so I was able to move it to a safer place. But the car was inoperable for about an hour and a half.

Ford Bronco Sport completely stalled at a traffic intersection nearly causing an accident. All power was off, including lights, doors, and starter. Taking car to dealer on Monday, closed during the weekend.
