2021 Ford Bronco Sport Powertrain (other) Problems

The vehicle's entire powertrain and transmission system failed completely. The vehicle will not turn on, will not start, and the electronic rotary gear shifter is physically locked out, refusing to shift into Park or Neutral. The transmission assembly component is currently available for physical inspection upon request. The sudden loss of powertrain and electrical control module communication caused an immediate loss of motive power, stalling the vehicle and leaving it completely stranded and un-drivable. The physical lockout of the shifter mechanism prevents rolling or shifting the asset safely, creating an immediate rollaway or crash hazard if stranded on an active roadway. The car was also jerking vilolently in the middle of an intersection almost causing an accident where we would’ve been rear ended. Yes. The failure was formally diagnosed and confirmed by an authorized dealership, Jim Taylor Ford in [XXX], under Repair Order (RO) #XXX. The component has been physically inspected and diagnosed by the certified technicians at Jim Taylor Ford dealership, who confirmed a total internal failure. They have ordered an entire replacement transmission assembly under Ford Part Number LX6Z-7000-F and Fluid XT-12-QULV. Symptoms and warning signs began showing around XXX, starting with minor shift jerking then eventually turning into violent jerking within a few days. The vehicle suffered from electrical system degradation and complete module power loss, which directly aligns with the known failure symptoms of Ford's active Powertrain Control Module (PCM) and battery safety recalls (such as Campaign 24S24). Ford Corporate was contacted but is refusing to cover this catastrophic mechanical destruction under the safety recall mandate due to the vehicle's mileage (118,365 miles), despite the physical damage being explicitly caused by the unaddressed manufacturer safety defect.

I had recalls for body control module and power train control module calibration updates. i took it to my ford dealership on august 12th, 2026 they had it done with within the day i picked it up. within a week after (i don’t drive my car much just to work mostly) i had an error come up on my dash saying the powertrain control had failed and i was unable to put my car in park. i immediately called the dealership they asked me to bring it back in. they ended up giving me a loaner vehicle and was with out my car for 2 weeks before I called and asked for an update. they said they were so sorry the transmission was compromised and i was going to have to pay $11,500 for a new one. I had never had issues with my transmission before bringing it in for my recalls to be addressed. i am still without my car and figuring out what to do next.

Car is failing to pick up speed and shuttering around 20mph to 60mph. Took it to the dealer and they said it’s the transmission. Im currently in talks with dealership about a goodwill repair. I’m at approx 65000 miles and warranty ended at 60000. I previously contacted Ford dealership to complain about the issue before the warranty was up. I was told I would have to pay $149 for a diagnostic on the vehicle so I took it to my repairman and no codes came up. He changed the spark plugs and still it shuttered. So I took it to the dealership and that’s when they told me they think it’s the transmission. There are serveral complaints about this and communications from the manufacturer especially about the shutter and no codes I complained about this when I first bought the car and was told nothing was found. I take care of my vehicle. It’s inspected every year and oil changes and maintenance are done on schedule. I don’t take it to the Ford garage because it is very expensive and a I have a mechanic that I trust. A car with this many miles that is maintained should not need a new transmission and I feel that I my goodwill was paying good money for a car that is not safe to drive. They told me I would have to pay for repairs until I mentioned a goodwill offer. I could see it the car had been driven off road or had a ton of miles but neither of those is true. They gave the car back to me until I hear back from the dealership. They never told me not to drive it. It’s been a week since they diagnosed it. After researching there are several complaints and communications from the manufacturer about this. I can only pray that they will handle this appropriately.

My 2021 Ford Bronco Sport is subject to Ford Safety Recall 25S76 / NHTSA Recall 25V467 concerning cracked fuel injectors that may leak fuel and create an under-hood fire risk. This recall was issued in July 2025. Approximately 14 months later, Ford still has not made the final repair available for my vehicle. I had Ford’s interim PCM software update performed by an authorized Ford dealer on December 12, 2025. My repair order specifically identifies the work as “Campaign number: 25S76 POWERTRAIN CONTROL MODULE PCM SOFTWARE UPDATE.” The replacement parts necessary for the final remedy have never been installed on my vehicle. Ford has repeatedly moved the anticipated availability date for the final remedy. I was previously told September 2026. On September 4, 2026, after spending approximately an hour on the telephone with Ford, I was told it could now be October. I am also concerned about the information Ford is providing to owners through its own app. Despite the fact that the final recall remedy has not been performed on my vehicle, the Ford app currently displays a green checkmark and states “0 active recalls.” There is also no unresolved recall shown in my alert history. This creates the impression that my vehicle has no outstanding safety recall even though Ford confirmed to me that the permanent remedy has not been completed and the required replacement parts are still unavailable. I am concerned both about the approximately 14-month delay in providing a final remedy for a defect involving potential fuel leakage and fire, and about Ford’s consumer-facing system representing that there are zero active recalls after completion of only the interim software update. I am requesting that NHTSA review Ford’s continuing delay in providing the final remedy for Recall 25V467/25S76 and the manner in which Ford is communicating the recall status to owners who have completed the interim software update but have not received the final remedy.

When making a slower turn mainly when turning to the right or backing up to the right the RS rear wheel is intermittently locking upor dragging and letting loose multiple times in a row. It does it turning to the left but not as bad. This issue causes the vehicle to not want to drive correctly or want to move especially when at an intersection turning right so I have to give it excessive gas to get it going, this issue also is making it very dangerous when pulling out when on a busier road or highway . I had my Laporte, Indiana Ford dealership check it out and they agree with me on the issue it's having, they said it's the drive internals in the rear end are bad possibly due to a faulty vent tube that lets water and dirt into the rear end causing the fluid to get contaminated, Ford knows about this issue and has a update vent tube. So I'm having to pay For the repairs myself $3000.00 and the dealership said it may take a month to get the parts, I asked them what will happen if I keep driving my vehicle till/if/or whenever it gets fixed their response was it will get worse and eventually detonate and destroy itself. While pulling out onto a busy road that isn't remotely safe! This issue started about two weeks ago around the second week of July 2026 and appears to be getting progressly worse, no warning lights at all came on it started speraticly but is constant now.

The vehicle failed to shift back into Drive after being placed in Park, rendering it inoperable. As a result, the vehicle had to be pushed out of a busy driveway and towed to a local repair shop. The local repair shop was unable to diagnose or repair the issue because the required diagnostic equipment is specific to Ford vehicles and was not available to them. The shop advised that the transmission may have failed. After researching the issue, transmission failure has been reported as a known concern affecting early-model Ford Bronco Sport vehicles. Because the local shop could not complete the repair, the vehicle had to be towed a second time to the nearest Ford dealership. The Ford dealership confirmed a transmission failure and determined that the transmission required replacement. The dealership replaced the transmission at a total cost of $10,971.48. At the time of failure, the vehicle had fewer than 75,000 miles on the odometer. Given the relatively low mileage and the significant cost of repair, a complete transmission failure under normal operating conditions raises serious concerns regarding the reliability and durability of this component. The Ford dealership's description of the diagnosis, repairs performed, and parts replaced is provided below. 7000: *TRANSMISSION REPAIRS TRANSMISSION DIAGNOSIS (NOT SHIFTING PROPERLY, LEAKS, OTHER) - C/S: TRANS SEEMS TO NO GO INTO GEARS, WAS AT ANOTHER SHOP WHO COULD NOT REPAIR, ADVISE ON NEEDED REPAIRS PLEASE WENT FOR TEST DRIVE - VERIFIED CONCERN. PULLED VEHICLE INTO SERVICE BAY. SCANNED CODES - FOUND P07E1 UNABLE TO ENGAGE NEUTRAL. CHECKED OIL LEVEL AND CONDITION - WAS FULL BUT HAD CLUTCH AND METAL DEBRIS PRESENT. RECOMMEND TRANS REPLACEMENT.

In January of 2026, I took my 2021 Ford bronco sport Outer Banks to the dealership because my car had a wrench light come on and it went into limp mode. Supposedly it was fixed and now it is April 2026 and my car went into limp mode again, it would not shift in the park and would not start and now the dealership is telling me that there’s transmission issues but from what I’ve read, there is clearly been a lot of transmission issues in these vehicles.

I have 130,000 miles on my 2021 Ford Bronco sport. With no warning I'm unable to put vehicle in gear. I attempt to put the car into drive, then reverse and it will not go. The gear gets stuck in park, but unable to park, The car instructs me to intiated emergency park with many warning lights appearing. when driving it jerks , make grinding noises, and I even lost momentum. Ford said the help line states they have attempted to fix the codes and replace the parts on the inside of the transmission and no luck. Ford recommends a new transmission. I believe the 2021 Bronco sport have a faulty transmission and replacing with another will result with the same issue due to the transmission being a close system it isn't preventable. Many other owners have experienced this very same safety issue and Ford should address ot and be responsible.

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.
