My daughter was involved in a single vehicle mishap where she jumped a curb at approximately 15 to 20 mph, blew out three tires, and damaged the right passenger front bumper as well as the right and left front quarter panels. The right front tire is bent inward and the left front is bent outward. Through all of this, the driver's side airbag never deployed. I had to guesstimate the mileage below at 53k as I don't have it with me where I am filing this report.
