I have had issues dating back to when I first got the car with rough idling and it turning off while idling. Most recently about 2 weeks ago experienced inability to turn the car on after fueling with gas. Rough idling and turning off while idling were also associated with gas filling. I took this car to Ford dealership multiple times. Check engine light came on associated with EVAP leak code. Ford dealership unable to diagnosis. I took to an independent mechanic who diagnosed in 10 minutes it is an EVAP purge valve malfunction and that likely this had been defective for some time. I reported this to ford and they refuse to compensate for this. I have seen multiple reports online of same issue with other ford bronco sport dealers. This failure seems abnormally premature and defective design. Concerning it results in loss of power of the vehicle as well.

Continue to have major safety concerns over this car. Had new issue of car not starting after refueling. Brought it in to dealership on Friday 9/25 and check engine light indicated EVAP problem code. Dealership at first refused to evaluate EVAP telling me was not related. Then then found a clogged hose but did not repair the EVAP and on 09/28 my check engine light came back on again. I called dealership and ford corporate still with no plan as they say they will not cover repair or rental. This is in light of having had the car turn off spontaneously while driving as recent as December. I am very concerned this may be linked to fuel injector recall which has no remedy and do not feel safe driving this car.

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.
