The vehicle was parked in my parking garage and rolled away causing a collision. There were no warning lights indicating an issue. The vehicle is currently sitting at a shop awaiting warranty paperwork for a transmission replacement that was done last year.

The car caught fire the morning of Dec 11, 2024 while the vehicle's owner was driving their children to school. There are photos and a fire report is being generated. The vehicle's owner and her children could have been killed. Early indications are that the fire was caused by the same faulty engine/exhaust system defect that the owner has been complaining to Ford about for years. It is assumed the fire report will confirm that. For the past two or more years the vehicle has been emitting exhaust fumes into the passenger compartment of the vehicle while driving. This has caused the vehicle's owner and her children to get sick and forced them to drive the vehicle with the windows down at all times even in cold weather. Ford's dealers have confirmed the problem several times, but either could not or refused to fix it.

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 Later Release verdict →
