- Summary
- Some vehicles may exhibit water leaking into the passenger compartment from the rear door through the bottom of the service hole behind the rear door trim during rain or when washing the vehicle. This is caused by one of the following: Since the material of the seal rubber is not resistant to surfactants, the rubber deteriorates when the vehicle is washed and allows water to penetrate into the seal rubber of the service hole cover. The lower tabs of the service hole cover may not have been completely engaged at the factory. To eliminate this concern, the service-hole cover has been modified. NOTE: It is a tentative change.
Owners of these vehicles have filed 12 complaints in the body category.
