I called Continental and they set up a file #4143053155 and told me to take it to the dealer for inspection. I took it back to Van Horn In Lomira WI for that inspection on 12/9/22.

The tires are Continental Pro Contract tx P225/R65/17.”

How we read this (methodology)

How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2021 Ford Bronco Sport draws about 111.5 complaints per year on the road, ranking 1 of 4 among the Ford Bronco Sport model years we have ingested (1 = most complaints per year on road).
