Component failure is the radio not coming on, reading audio off, no matter pressing audio on. Component failure is the radio loading and never comes on. Issue with AIPM communication issues with radio. Screen sometimes doesn’t come on or locks up. Major issue. Dealership worked on it but having issues figuring it out. Similar to recent recall for 2021 ford bronco but it doesn’t include the sport.

Catastrophic engine failure. Sudden. Started my car in the morning. Engine was running rough. Drove about 1/2 mile, engine continued to get worse. Returned home. decided to get engine codes checked. Check engine lights did not come on until this incident. Couldn't keep engine running. Kept trying to restart. Heard weird noise in engine and engine seized. Car had 62,800 miles on it, just over the 5 yr/60,000 warranty. Had the car towed to local Ford dealership. They verified that the engine was seized and that I needed a new engine. They found a lot of coolant in the engine oil along with a lot of metal flakes in the oil. They called it a catastrophic failure and speculated that it could be piston or valve destruction. They did not tear down the engine to determine the cause. They wanted an additional 2,000 to do that. (I kept the old seized engine). This failure could leave the owner stranded and in a very unsafe situation. I don't know what this failure would do to the drivability of the vehicle in traffic or on the highway.

If my car can burn up because of this issue, why isn't a replacement part available? Is Ford going to wait till it burns? Seems to me if the problem is known you'd rather fix it than pay out lawsuits.

Mar 3, 2026Transmission & drivetrain

dragging, grinding, or rubbing noises from the rear of a 2021 Bronco Sport during low-speed turns are a known issue commonly associated with a faulty rear drive unit (RDU), often appearing around 40k-60k miles. This problem, sometimes described as a, shutter or chattering, is often tied to contaminated fluid caused by a defective or improperly designed vent hose that allows debris to enter the system.

Mar 2, 2026Transmission & drivetrain

The transmission failed to shift out of a forward gear when selected. Reverse was selected and the vehicle moved forward into a dangerous situation. It resisted stopping as the brakes were applied. There is no "key" to shut off. I was forced to vigorously apply the brakes to avoid a collision with a train. The car is undriveable. The dealer inspection and an independent inspection confirmed that the transmission was failing in a manner that they were both aware of. Replacement cost has proven to be prohibitive. Numerous warning lamps began to illuminate as the problem was discovered.

On 2/19/26 the Vehicle would not go in reverse. This is the second time the vehicle has failed to reverse. The vehicle was towed and fixed by don chalmers ford the first time this happened. Now they stated the vehicle was one day past warranty and would not tow/fix issue. I dropped the vehicle at dc ford on Friday 2/20. Today they called and said they think it is the same issue that was fixed with the transmission and would charge 6-8 thousand to fix it. More if we wanted a new transmission. I have read several reports from other consumers that the ford 2021 bronco sport has transmission issues. This vehicle has also had several recalls that I have had fixed by ford. All maintenance has been performed by ford as well. This is an unsafe vehicle and ford has failed to insure its costumers are safe and treated fairly.

Feb 11, 2026EngineFuel systemCrash

This vehicle is subject to NHTSA Recall 25V467 involving potential fuel injector cracking and risk of fuel leaking onto the engine, creating a fire hazard. The recall status shows “Remedy Not Yet Available,” leaving the defect unresolved. While driving, the vehicle suddenly displayed an engine overheating warning and immediately entered limp mode, causing abrupt loss of power. The vehicle decelerated unexpectedly and was not able to maintain normal driving speed. This created a dangerous situation in active traffic and required a safety tow. The sudden power reduction could have resulted in a rear-end collision or loss of vehicle control. There were no prior overheating warnings immediately before this incident. The failure occurred abruptly. A warning message appeared at the time of the event, followed by limp mode activation. The vehicle had to be towed to a dealership for inspection. Given that the open recall involves fuel injector cracking and potential fuel accumulation near hot engine components, there is concern that the unresolved recall condition may be related to engine overheating and loss of power. The vehicle remains under an active fire-risk recall, yet no repair remedy is available. Owners are left operating vehicles with a known safety defect and no corrective action timeline. The defect has not been remedied because parts are not available. The vehicle was inspected by a dealership after the overheating event. The primary safety concern is the combination of an open fire-risk recall and a sudden overheating/limp mode event causing abrupt power loss in traffic, creating a serious risk of injury. Due to this open recall with no available remedy, the vehicle cannot be listed or rented on a peer-to-peer vehicle sharing platform, resulting in loss of legitimate income. The vehicle was previously eligible for use, but is now restricted solely because the safety recall remains unresolved without a repair solution. Owners are financially impacted.

Since my car hit 40000 miles it has had nothing but issues. I've had it in the shop at least 10 times. My brakes went out while driving with my [XXX] old, I've had loss of power, smell of exhaust in the cabin for the last 3 months and dealership says it can't be fixed, yesterday I had complete engine failure while on the freeway. Stalled and wouldn't start back up for 5 min. The dealership has never fully fixed anything but has only updated the computer system. I feel very unsafe in this vehicle. We still owe on this vehicle so trading it in is not an option since its not even worth the down payment I put down. It has a fuel injector recall that can't be fixed yet due to not having the parts available. What are we suppose to do if we can't drive the vehicle and can't buy a new one.

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.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ford Bronco Sport Early Release verdict →
