ELECTRICAL SYSTEM, ENGINE
Husbands Ford Bronco sport has had a constant smell of exhaust that fills the interior of the vehicle since purchased. Dealer said there was a “recall and fixed the problem”. It only lasted 2 days until it began again. My husband gets lightheaded and dizzy while driving and has to stop and roll his windows down. He almost passed out while driving home with our children. Dealership says “this is a common problem and Ford doesn’t have enough parts at the moment to fix it and it will be around 2-3 months until they do.” Also, the car has suddenly stopped while driving or won’t start back up. It has to sit for a day or so and then it will start. Tried replacing the battery and it didn’t work. We’ve had to leave it sitting in random parking lots several times.

POWER TRAIN
This is a correction and expansion to complaint #11650564. My 2021 Ford Bronco Sport has now experienced complete transmission failure at approx. 86,000 miles, following earlier rear differential (RDU) failure at 60,600 miles. Both major drivetrain components failed well before expected lifespan under normal, mostly interstate driving. The vehicle has never been off-roaded. Transmission symptoms include shuddering, fluttering, failure to engage park, and severe gear engagement issues. Critically, the vehicle would power forward while placed in neutral — it was not rolling. The wheels received torque while in neutral, which should not happen. Reverse gear would also engage forward motion, and drive would fail to engage at all unless I toggled 4WD low. Park would not hold the vehicle, requiring the parking brake to prevent movement. One serious safety incident occurred when stop-start activated at a red light and the car failed to re-engage drive, leaving me stranded in live traffic. In another case, reverse engaged late and suddenly surged backward near a building. I scanned the vehicle using FORScan and found a code for stuck solenoid A (failure to engage park). I asked the dealer to check the valve body — they refused, claiming the transmission was “shot” without verifying the issue. Ford issued SSM 49930, internally on Aug 5 2022 acknowledging these behaviors in this transmission. These are not just mechanical issues — they are dangerous. I respectfully request NHTSA investigate the 8F35 transmission used in the 2021 Bronco Sport.

POWER TRAIN, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
Purchased the Bronco Sport brand new in September 2021. Almost from the outset, the vehicle has been a nightmare. We just purchased our third battery. The vehicle died at an intersection and had to be towed to the dealership. They replaced the battery but it again failed. We have experienced numerous electrical issues with the vehicle as well as with the brakes and the power train. We have had the shift system fault notification come on several times. We took it in to the dealership who made some repairs and the notification went away for awhile. However, most recently, we were driving the vehicle down the interstate when it suddenly would not accelerate. We were very lucky to be able to maneuver the vehicle onto the shoulder. After a few minutes, the vehicle started and we were able to drive it home very slowly on side roads. We took the Bronco Sport to the dealership again and notified them of the multiple trips we had made there to fix this code issue. The dealership did a diagnostic and had a transmission specialist look at the car. The conclusion was that we needed a brand new transmission to the tune of $11K. Additionally, the dealership stated that we likely had rear differential issues as well - the subject of one of the many recalls on this lemon of a vehicle. We have not had the diagnostic performed as we are waiting on Ford to let us know if they will buy back the vehicle. Again, we purchased the car new and it has about 80K miles on it. There is no discernible reason for the transmission to fail on a car this new which has primarily been driven to and from work. A quick Google and social media search shows this is a pervasive problem with the 2021 Bronco Sport - many owners are experiencing electrical, power train and transmission issues. NHTSA needs to investigate this matter before someone is seriously injured or killed because of the failure of Ford in manufacturing the 2021 Bronco Sport.

SEAT BELTS, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
Ford has a battery that corrodes while driving and can shut off car. This is dangerous. On top of that, they had to extend warranty on drivers seat belt and fuel injector but will only allow those to be replaced once they break. My car is unsafe to drive. Imagine, car shuts off and seat belt breaks. This is dangerous.

UNKNOWN OR OTHER
The vehicle sometimes ran a little rough while idle at drive thru. Then week later the push start did not work... engine turned over but not start. After 6 times it finally started and ran good on way home. Later that week, kept having traffic lights in town turn red... constant slow so stop and go. Vehicle started sputtering and stalled out in the highway and died in middle of road and would not start. Had to let it sit several minutes and it finally started. We immediately turned around and went home. Made appointment at dealership. Tried to start vehicle to drop off for appointment but would not start. Had towed in. They claim fuel pump replacement required. Drove home and ran ok. Next day power inconsistent and runs rough at start and slow speed with one push start did not work. Reporting since my spouse is in a wheelchair and can not walk. This vehicle is only one we have that my spouse can get in due to disability and I am seriously concerned if vehicle stalls out on public highway again it is likely to result in an accident and he gets seriously hurt. Never had a vehicle I felt unsafe to have my family be in before and do not think it is safe for this vehicle be on the highway.

The water pump has been replaced twice already and the water pump needs to be replaced again at 105,000 miles. This will be the fourth water pump this vehicle has. The originally came with, two replacements, and now the one that it needs because it is leaking like the previous three. The turbo charger failed and was burning oil. That was replaced. A month later it is back at the dealership being replaced again

My car broke down and couldn’t start. Leaving me stranded 6 hours away from my house. I had to stay in a hotel and get my car fixed the next day. It was a temporary fix because there is no solution for the problem. I had to pay for a new battery because there is not a fix for the problem.

FUEL/PROPULSION SYSTEM
Purge valve went bad, it was causing the vehicle to try to stall and dropping down to very low rim, always happened after fueling and would sometimes hesitate to go when accelerator was pushed. I had it stall on my trying to pull on to [XXX] in Florida from an exit. That could have been very bad. And I've noticed way too many other people online and in forums having the same concern. Do to safety concerns i paid to have mine replaced but do not feel like it should have already went out this soon. The date i included below is for the last incident, this issues started over a year ago and has slowly gotten worse. I did mention this back then to my service dept but was told it just probably hadn't built up enough pressure in the tank yet after fueling.
