“Purchased used with 83,000 miles. Currently 100,000. The intermittently reports a failure in the passenger restraint system. When examined by a qualified mechanic, there is no indication of an issue with any of the passenger restraint systems.

Dealership has stated there is a recall on similar vehicles during the same year, but not this vehicle even though it uses the same components.”
