Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Purchased a Ford Bronco Sport brand new in 2021. I received a recall notice for my bronco sport last July. I took my vehicle to the Ford dealership and they told me there was no remedy available. The recall states that my vehicle could catch on fire and crash at any time while I’m driving it. Ford still does not have a remedy almost a year later and they don’t know when they will have one. They don’t have parts even though my VIN number is affected. Ford expects me to risk my life and the life of my passengers, who happen to be my grandsons, by driving this vehicle on a daily basis. At any time, my car can catch on fire because of the fuel injector recall. I filed a claim with the Ford buyback program, but was denied because my vehicle warranty has expired. The recall didn’t even come out until after my warranty had expired. Recall info: Campaign 25S76/25V467
There has been a NHTSA recall for AWD module on 2021 and some newer Bronco sports. The letter in reference to this problem dates 4/9/2021 to include only certain VIN at the time based on manufacturing sites. I feel there has been an underestimation of vehicles/parts affected on this recall based on the fact that it included very limited vehicles only 4 month into production. There have been several more known to be experiencing this same exact issues as evidenced by many reviews online by bronco sport owners experiencing the same problem. Specifically detailing the triggering of same codes (mentioned in this letter) leading to faulty AWD module diagnosis and replacement at the owners cost. I have reached out to Ford North America to file a claim and have been told my VIN is not included, without even comparing with specific part serial number. In addition, I have found the part #LX6Z-7P238-AANP as replacement referred in the letter has now recently been replaced with a newer more expensive version with a different name and part number M1PZ*7P238*C. I also find it significant that the old part is still for sale at a now discounted price on ford OEM website as of today. I believe this indicates there are known problems with this original part causing need for an updated replacement. Given this evidence l, I feel it is only fair that Ford acknowledges vehicles with the same problem/part are experiencing these issues and be willing to extend the recall. I have reached out to North American Ford and have a claim #Cxh-07823745-c2n6y4. In hopes that they will do what’s right for this customer and replace at no charge, aware that it is defective. My vehicle is currently at the dealership and I am hoping for a fair resolution. Thank you for your time and attention.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
My transmission is surging at low speeds all the way from takeoff to about 60mph. No engine or transmission codes.
ENGINE SPUTTERING BETWEEN 1ST AND 2ND GEAR. RECALL IS STILL NOT RESOLVED REGARDING COMPUTER UPDATE AT THIS TIME AND DEALERSHIP SAID NO CODE NO REPAIR FOR OVER A YEAR. NOW I MUST REPLACE THE TRANSMISSION. FORD HAS KNOWN ABOUT THE ISSUE MANY TSB ISSUED FOR THE POWERTRAIN ISSUE.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The bronco sport was being driven, suddenly an gasoline odor was slightly noticed, it was almost dismissed because the intersection the vehicle was currently at has 4 gas stations. The SUV suddenly turned off, alerts popped up on the screen and smoke began to rise from underneath the hood. As the vehicle was exited, the gas odor was noticeable and flames began to shoot from the engine bay. Within a minute the flames had engulfed the whole front end of the vehicle into the interior.
The contact owns a 2021 Ford Bronco Sport. The contact stated that the check engine warning light illuminated. There was an abnormal odor of exhaust fumes inside the vehicle. Initially, the driver thought it emerged from other vehicles; however, a passenger smelled exhaust fumes, became sick, and vomited once the driver pulled over. The Ford mobile app failed to display any failure codes. The contact related the failure to NHTSA Campaign Number: 25V467000 (Fuel System, Gasoline). The vehicle was taken to a local dealer, where diagnostic trouble codes for the engine were cleared. The fuel vapor was purged, and the valve was replaced; however, the failure recurred. The vehicle was then taken to an independent mechanic shop, where it was diagnosed that the catalytic converter was fractured. The catalytic converter was replaced, and the fuel injector was serviced. The manufacturer was not contacted. The failure mileage was approximately 67,830.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The contact owns a 2021 Ford Bronco Sport. The contact stated that the daughter had reported that while in a parking lot, the brakes unintendedly engaged, and then the vehicle suddenly accelerated. The driver immediately applied the brakes to stop the vehicle. The contact was able to duplicate the failure while attempting to park the vehicle. The messages "Power Train Malfunction" and "Reduced Power" were displayed, the power train warning light illuminated, and the parking brake warning light flashed continuously. The vehicle was being towed to the dealer. The vehicle was not yet diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was 108,236.
The front and rear brake system has repeatedly malfunctioned across at least 7 dealer visits since 2022 on my 2021 Ford Bronco Sport (VIN: [XXX] ). Brake squealing and grinding (particularly in reverse at low speeds) have persisted despite multiple repair attempts. Ford's own SSM 52515 acknowledges engineering was working on a fix and that rotor resurfacing is "not a guaranteed fix." TSB 23-2308 was performed in March 2024 (caliper bushings/guide pins replaced). In June 2024 a dealer verbally confirmed a brake recall was coming in Oct/Nov 2024 and that rotors would be covered — that recall never materialized. Front brake pads were replaced under Recall 21C31 in September 2022 at ~8,797 miles. Front pads and rotors required full replacement again in April 2025 at ~28,833 miles — just 20,000 miles later and well below the typical 50,000–70,000 mile service life — at my out-of-pocket cost of $747. Rear brakes were documented as "in the red" in January 2026 at ~38,000 miles. The vehicle is currently at a Ford dealership. In August 2024, one dealer attributed the issue to driving habits despite Ford's own TSBs acknowledging the defect. Brake wear across both axles is abnormally premature for a [XXX] vehicle. Across brake-related and recall visits the vehicle has been out of service for approximately 30 days. Relevant: TSB 23-2308, TSB 25-2143, SSM 52515 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased the 2021 Ford Bronco Sport in August of 2025. There were issues after about a week with all kinds of messages of components not working cycling through constantly on the display. The electric brake would engage on its own while parked and had to be shut off before I could go forwards after starting the vehicle. I took it to the dealership where I bought it and after a few days they said it was a batter issue and replaced it at no cost to me. It worked okay for a short time and then I had the same issues and now added to those were it wouldn't start for at least 15 minutes and several tries. Cruise Control could not be used and the turn signals would not work while all of the messages were displaying. The windshield wipers would only work at the highest setting and the rear wipers would not work at all. I took it to another Ford Dealership and they said it was an electrical wiring issue that they found. The High Speed Cam wiring is what they found a break in and they fixed it and cleared the codes. I paid $450 for this repair. Just 4 days later the issues have returned. Messages about components not working, this time the right turn signal would not shut off. I am concerned about the safety issues while driving with my turn signal stuck on. I called the same Ford dealership and they can get it in on Friday so that I can have a loaner car. I just don't feel safe driving the Bronco. I don't have the money to loose on trying to trade it in with these issue. Help!!!!

There is a load moaning sound when backing the vehicle up or making a turn which significantly effects steering and stoping. Ford dealership said that tires were not rubbing body and tie rods were ok. This ford bronco sport only has 25K miles on it and never taken off road. Ford said to live with the sound until it bothered us? They said that it didn't need brakes but a new brake job could possibly fix problem? Independent repair shop said that it wasn't a brake issue but didn't know what the problem was. This load sound must be a defect for this vehicle because others on the web have expressed the same problem but ford has not put out a recall as of this date.
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
Vehicle would not start on two occasions, both times the vehicle was jumped and started. On the third occasion the car would not start, the electrical panel flashed all the warning lights and the dashboard continually flashed on and off. It was towed to the Ford Dealership in Oxford, MS in December 2024. The dealership looked over the car, no other issues and advised that this was likely a recall and recommended a battery replacement which I did. I paid $202.65 for the repairs and in February I received a notice for 12 Volt battery recall but no instructions were provided to seek reimbursement nor was there any recall fix given (time was Q2 2025). The instrumental panel upon attempting to the start the vehicle would light up but the engine would not turn over, all warning lights would come on. Yes the vehicle is available for inspection.

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
Rear Belt Monitor Fault continues to be an issue. We received this warning light and supposedly had this repaired in October of 2024. The dealership replaced the rear seat belt buckle and reset the codes. This worked for a while but now is happening again. Additionally, we are receiving an airbag warning related to the rear belt monitor. When driving even short distances the warning light appears on screen maybe 5 or 6 times. If a seat belt is disconnected there is no audible warning alert or light to let the driver know that it is not in use. I believe this may be a faulty restraint control module rather than an actual seat belt issue. This is definitely a safety issue regarding restraints and airbags. I've heard of this issue in several Bronco sports, and Mavericks.

My passenger seat heater caught on fire, it was very scary but I was able to put it out with sugar after I pulled over and figured out where the smell was coming from. I took it to my dealer for an inspection but I feel as though they were just trying to cover their side of everything and said “the seat heater did not cause the fire unfortunately”. I am currently in contact with ford and my insurance company. My insurance so far just says they need to investigate more but also that my claim is closed so I’m honestly just at a loss and confused about that and will be reaching out to them again soon. There was no warning at all and I’m glad I caught it when I did because I had glasses cleaner in my passenger side door that is very flammable.

Tires & wheels
Reports naming tires, wheels, hubs, or the tire-pressure monitoring system.
From owner reports, verbatim
At 21,000 miles on Bronco I purchased as new, I received an alert on the dash for low pressure on all 4 tires. I stopped the car and all 4 have bulges in the same place. I called Continental and they set up a file #4143053155 and told me to take it to the dealer for inspection. I took it back to Van Horn In Lomira WI for that inspection on 12/9/22. They took pictures and sent them to Continental who tells me that this is normal for tires to have bulges in the side. I am very concerned if the tires are actually safe to drive on. The tires are Continental Pro Contract tx P225/R65/17.
