The car has now on three separate occasions lost power while driving. As I slow down coming to stop or reducing speed car will completely lose power and then struggle to restart. Both occasions were on busy roads. Additionally, when you put fuel in the car it does not turn on right away it smells like fuel is burning and fumes enter into the cabin. When you push start after fueling it struggles to turn car on to drive. There is full accessory power but no power to drive the car even when giving it gas. It requires multiple attempts at starting the vehicle and it will tremble and shake once it starts running and stutters as if about to shut off even when you start driving it. Today it powered down again while driving and we avoided and accident but it is becoming dangerous to drive the vehicle due to its unpredictable shutting down.

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!!

The car caught fire the morning of Dec 11, 2024 while the vehicle's owner was driving their children to school. There are photos and a fire report is being generated. The vehicle's owner and her children could have been killed. Early indications are that the fire was caused by the same faulty engine/exhaust system defect that the owner has been complaining to Ford about for years. It is assumed the fire report will confirm that. For the past two or more years the vehicle has been emitting exhaust fumes into the passenger compartment of the vehicle while driving. This has caused the vehicle's owner and her children to get sick and forced them to drive the vehicle with the windows down at all times even in cold weather. Ford's dealers have confirmed the problem several times, but either could not or refused to fix it. A summary of the vehicle's service history is included below: 35,662 miles Customer states inside of vehicle smells like exhaust. 37,431 miles Inside of vehicle smells like exhaust. 39,856 miles inside of vehicle smells like exhaust. confirmed customers concern found cat warped at mating surface to turbo replacement required. 46,832 miles Fumes getting inside the Cab, seems to be blowing in from vents. Misdiagnosed as blower motor electrical smell and missed broken catalyst. 47,300 miles Customer had car towed into shop stating car was shaking and smelled flumes inside the car. Verified concern that exhaust smell was present in car and loud noise was coming from engine, found catalytic converter had broken at flange to turbo causing exhaust leak. Recommend new catalytic converter, removed and replaced catalytic converter. Low pressure fuel injectors are leaking. Verified customer concern, found fuel seeping out of all 3 low side injectors, recommend injector replacement, remove and replaced all 3 low side fuel injectors, found no other leak at this time. Found injectors were leaking fuel. 47,829 miles Check engine light. Remove and replace purge valve.

The contact owns a 2021 Ford Bronco Sport. The contact stated while driving at an undisclosed speed, the vehicle started losing motive power. A message advising a power train failure was displayed. The driver was able to exit the highway at 15 MPH. The vehicle was driven to a nearby dealer, where the computer was rebooted; however, the failure recurred several times while driving. The vehicle was taken back to the dealer several times, and the transmission was rebuilt. The contact stated that the failure had been recurring while driving.

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 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.

The evaporative emissions system failure involving the purge valve and vapor canister purge valve is a recurrent issue on this car and has been reported by hundreds if not thousand of bronco sport owners. The safety issue that arises from this is that we are emitting more fuel vapors into the atmosphere, not only does this not help with emissions control into the atmosphere, but it decreases fuel efficiency and increases gasoline smell into the vehicles cabin.

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

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 knew i would be having Transmission issues so early in the life of the vehicle, i wouldn't have purchased a new car in the first place. This is definitely a safety hazard and i am sure this is not the only Bronco Sport with a torque converter being faulty, causing the transmission to slip.

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 sat for 2 weeks before Ford service confirmed the fuel injectors needed to be replaced as part of the 22N18 recall, but also said the battery was bad. Prior to this incident, I had 0 issues other than the issue in January. I had no notifications of battery issues in my app, no dimming of lights, etc. I had to pay over $300 to replace the battery so Ford could do "further testing" since I was a month out of the 36 month warranty. I picked up my car on 7/26/24 and when I started it in the bay, I smelled burning and even asked a different employee who confirmed he smelled it, and we were told by the manager that it was "old fuel burning off." He assured me the car was fine. I noticed my car being slow to start and having an odd issue whenever I turned, like a rubbing sound and it still had a burning smell even though I had to pay Ford to replace the cabin air filter. This was all new. Then, 8/18/24, my car again would not start, all the electrical lit up and the brakes were locked up. My car started smoking again under the hood as it kept trying to start. We could hear sounds like it was trying to start. Again, car is being towed to Ford.

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 4wd fault error. Contacted Ford immediately. The next morning, I started the car and the errors were gone, but I still wanted to get it checked out, so headed towards Ford. Stopped for gas on my way, but after filling up the tank, my car wouldn't start again. This time far worse than the first time, as something under the hood starting making a clanking noise, and smoke started coming out from under the hood, and smelled like electrical fire. The noise continued to get louder, and the smoke more violent. Finally cut the battery cable since the car was smoking, at the gas pump, on a busy Saturday, minutes before noon. Very scary situation, especially with kids in the car. We are OK. We are safe. But holy crap!

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.
