POWER TRAIN
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.

!!!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.

POWER TRAIN
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.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
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.

ELECTRICAL SYSTEM
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.

POWER TRAIN
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.

STEERING, SERVICE BRAKES
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.
