Subject
The driver’s side rear under body ladder rail on about 100 of the above vehicles may have been built with reduced corrosion protection which may, in certain circumstances, eventually result in a loose left rear seat mount or reduced strength of the rear floor pan due to premature corrosion. A loose left rear seat mount or reduced strength of the rear floor pan due to corrosion could, during a vehicle crash, allow two of the six attachment fasteners for the left rear seat to not be retained to the floor pan and/or the left rear floor pan structural frame member to buckle, which may increase the risk of injury.
Repair
Inspect the left side (driver’s side) rear longitudinal under body ladder rail date code marking. If repair is needed, the interior and exterior of the left side rear under body ladder rail will be coated with three-part rust protection, or if deemed unrepairable, the vehicle will be repurchased.
