My wife's 2021 Ford Bronco Sport has had a complete transmission failure and the vehicle has less than 75,000 miles on it. We're told by Ford that the Powertrain warranty ends after 60,000 miles. This has been a disaster for us as we're paying a note on a vehicle that we cannot drive because it will cost $10-11K to repair. I've never owned a vehicle that has had so many problems in my life.

I was driving home from work one day on a Monday and my vehicle had a bunch of warning notifications pop up such as pre collision assist not available, blind spot assist not available, etc as well as a wrench icon popped up and stayed on stating to service 4wd. I stopped driving my vehicle until I could get it serviced. I then took my vehicle to ford to get it diagnosed on Friday of the same week ford stated they would be able to diagnose it for $150 then repair and labor costs would come after. Well they never looked at my vehicle Friday so they told me to bring it back the next Monday I brought it back they said they would diagnose it a few hours later I received a call stating they “think” it’s my AWD module located under the passenger seat but they would not know if that was the problem until they got under the seat and that would cost me an extra $500 for them to inspect it. From research I have been doing they should have been able to tell me if it was exactly that module or not by plugging a J2534 into the main module and using the FDRS application that all ford dealers use. From more research I have been doing this is a very common problem with 2021 ford broncos concerning the AWD module. The faulty AWD module could be caused from a faulty battery which was a recall on my specific vehicle they stated they tested my battery that day but I’m not sure if they actually did because I tested it at home and it was reading low and I just had that battery replaced by ford in M

At 70K automatic transmission stated to cause jerking motions while in lower speeds when starting to drive from lower speeds. Took car to dealership and i need a new transmission. I have read on Bronco Forum from other Bronco Sport BADLANDS edition, that their transmission has failed too at various mileage, ranging from 30K-66K. Of course this is dangerous if there is a complete failure of transmission. FORD's warranty on power train ends at 36K. The cost is $8700 to replace. transmissions don't die at 70K. according to car experts, transmissions should last 120K-200K. I can't believe there is a recall for some Bronco Sports and not ALL Bronco Sports.

My 2021 Ford Bronco Sport Big Bend 1.5L EcoBoost (VIN: [XXX] ) suffered a turbocharger failure due to oil leakage, which caused overheating and smoke from the engine bay. The vehicle became unsafe to drive due to loss of power and risk of fire from leaking oil near hot engine components. I’ve found numerous reports online of similar failures in other 2021–2022 Bronco Sport 1.5L models, suggesting a possible design or component defect. This issue poses a serious safety concern, as the engine can overheat or lose power suddenly while driving, increasing the risk of crash or fire. Please investigate this matter to determine if a recall or safety campaign should be initiated to address recurring turbocharger and oil leak failures in these vehicles.

!!!ALWAYS GET A SECOND OPINION WITH "TRANSMISSION ISSUES"!!! I will NEVER get a Ford again! I'm updating my previous issue #11688946 I received my 2021 Ford Bronco Sport in early 2023. I noticed a shutter when accelerating from a stop, I took it to the dealership and had the 3rd fuel injector recall completed (still waiting for a remedy to the most recent #25V467). The dealership stated my vehicle should run fine now. The shutter persisted and worsened and a new issue developed, my RPM's would slightly bounce while going at a steady speed. 09/19/2025 BACK TO THE DEALERSHIP I GO!Just for them to "diagnose" the issue I had to pay $165.00. AND they tried to charge me double stating it took them 2hrs. My BS was dropped on less than 2hrs of them calling me. DIAGNOSIS: torque converter. They recommended a flush and fill for $300-$400. 09/25/2025 I bought an OBD-II and plugged in to see if there were any codes. The codes I got make way more sense than a new transmission. -U0140:00-08--BCM missing communication -U1A00:87-08--APIM private communication network malfunction -U2013:01-08-- Switch pack issue Also the EVAP system vapor pressure as well as Oxygen sensor current (B1-S1) is functioning incorrectly and randomly drops below the normal range. My transmission is fine... All they had to do is updated/reset my BCM when they had it as well as perform a "relearn". But they didn't!!! Clearly these are not always transmission issues but service work is what makes dealerships more money

RDU (Rear Drive Unit) is beginning to I think fail and I have read on other forums with other people saying there’s failed and can be a safety risk. They are put at risk if the RDU fails while driving resulting in an accident. I haven’t gone to the dealership yet or let anyone else know. I thought doing a simple fluid change would do but it still persist. I’ve done research to understand what’s wrong. There was no warning lights but shuddering or grinding noise would occur and I believe it appeared a few hundred miles ago then go worse overall.

While driving, the display screen shuts off and both the speedometer and tachometer loose power. The display is off anywhere from 10-30 seconds before it acts like the system is rebooting and the startup screen comes on. Then, after the startup screen has cycled, the display starts working again. This has happened 5 times now in the last week. I have not taken to a dealer yet but am planning on scheduling an appointment as soon as possible. There were no indication prior to the display going blank and it only started recently.

I own a 2021 Ford Bronco Sport that has had repeated premature failures of critical components. At ~52,000 miles the water pump failed and was replaced along with coolant and belts. Less than 21,000 miles later (at ~73,000 miles) the water pump has failed again, with coolant leakage and a burning coolant smell. Ford has issued TSB 23-2104 acknowledging coolant leaks at the water pump/hose connection, yet no recall or extended coverage has been offered. This is not the only issue. My alternator has also failed twice and required multiple replacements in under 4 years of ownership. Having two major components (water pump and alternator) fail repeatedly within such a short period clearly shows a systemic defect, not normal wear and tear. Safety risks: coolant leaks can drip or vaporize onto hot engine components, creating a fire hazard. Alternator failure risks sudden loss of power and stalling in traffic. Both are unacceptable in a vehicle this new. The dealership confirmed the latest water pump diagnosis and quoted over $1,000 in labor alone, placing an unreasonable financial burden on the owner. This is the second water pump and second alternator within 73,000 miles. Ford and its dealers know this is an ongoing issue in Bronco Sports, as confirmed by widespread owner reports and TSBs, but continue to deny responsibility. A recall or customer satisfaction program should be issued to address these repeated failures.

Seeing that the 2021 Does Bronco Sport has had a total of 16 transmission complaints/issues I'll go ahead and add mine. My Bronco sport started shuttering during acceleration as well as the RPM needle slightly bouncing up and down. I brought my Ford into the Ford dealership for a diagnosis, I paid $165 for them to look at it and them later tell me that my torque converter is going out. They recommended a flush and fill to help with the longevity, stating that would be between $300-$400. That's when I asked how much it would cost for them to fix the torque converter they stated between $3,500-$4,000. Really something I did not want to hear especially knowing that we are on our 15th recall but this one has no solution. Still waiting on the answers for recall #25S76 and #25V467.

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.

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.

I am reporting a serious and recurring issue with the catalytic converter on my 2021 Ford Bronco Sport (1.5L EcoBoost), which has resulted in reduced efficiency and partial blockage, causing exhaust gases to enter the cabin and triggering engine code P0171. My safety and the safety of others have been compromised because exhaust fumes, including carbon monoxide, have entered the cabin, which is particularly dangerous as I am currently pregnant. In addition, the engine experiences RPM fluctuations and revs up on its own, sometimes hesitating during acceleration, creating a risk of loss of control or accidents, and reduced engine efficiency contributes to unpredictable vehicle behavior. The problem has been confirmed by a dealership, which diagnosed the catalytic converter inefficiency and provided a $2,000 replacement quote. This issue has been widely reported among other 2021 Bronco Sport owners, indicating a recurring problem. The vehicle has been inspected by the dealership, which ran diagnostics and verified the codes. Prior to the failure, the Check Engine Light illuminated, and I experienced exhaust fumes in the cabin, unusual odors, reduced engine performance, and RPM surges with hesitation during acceleration, first appearing around 80,000. This defect poses not only a serious safety hazard, but also environmental concerns, as the failing catalytic converter increases emissions of harmful gases, including carbon monoxide, hydrocarbons, and nitrogen oxides, contributing

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.

The component is the fuel injector, which is a part of the engine's fuel delivery system. According to the recall notice from Ford, this component has the potential to crack. The component is known to be defective and has been inspected by a Ford dealership service department upon my request and was told there's no solution as of yet by Ford. ​My family's safety, including that of my toddler who is a daily passenger, is at significant risk due to the potential for an underhood fire. The recall notice explicitly states that a crack in the fuel injector could lead to a fuel leak, and "liquid fuel and or fuel vapor that accumulates near a sufficiently hot surface may ignite resulting in an underhood fire, increasing the risk of injury." This places my family at risk every time we operate the vehicle, as the threat of a fire is present with no permanent solution available.

I have 66,310 miles on my 2021 Ford Bronco Sport and recently found out that it needs a new transmission. Their quote for the transmission was $13,000… yes you read that right $13,000!!!! More importantly is the fact that the transmission crapped out at 66,310 miles… The dealership (Stamford Ford) told me there was NOTHING they could do as the warranty expired at 60K miles. After some research online it turns out that FORD BRONCO IS PLAGUED WITH TRANSMISSION ISSUES AND THEY REFUSE TO RECALL THEM. There are literally thousands of complaints from people with the same issue

The contact owns a 2021 Ford Bronco. The contact stated while driving 60 MPH, the vehicle started to lose motive power and was shaking abnormally. The contact depressed the accelerator pedal, and the RPM became elevated; however, the vehicle failed to respond as intended. The contact stated there was no warning light illuminated. The contact was able to exit the high and parked in a parking lot. The contact turned off and restarted the vehicle and became aware that the wrench symbol was displayed. The contact shifted into reverse to exit the parking lot and "Low Power Mode” warning light flashed on the instrument panel. The contact was able to drive the vehicle to a dealer at speeds below 30 MPH. The dealer diagnosed the vehicle and determined that the transmission had failed and needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V158000 (Power Train, Electrical System). The contact had replaced the 12-Volt battery prior to the failure because the battery failed to charge. The contact had the alternator checked by a battery shop and the battery was in operational condition. The manufacturer was informed of the failure and informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 82,000.

Reading these

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
