The problem
Chrysler (FCA US LLC) is recalling certain 2018 Jeep Wrangler vehicles. The rear under body ladder rail may corrode, possibly reducing the strength of the rear floor pan and causing the left rear seat mount to become loose.
The risk
If the floor pan strength is reduced and/or the rear seat mount becomes loose, the rear seat may detach in a crash, increasing the risk of injury.
The fix
Chrysler will notify owners, and dealers will inspect and, as necessary, coat the interior and exterior of the driver's side rear underbody ladder rail with three-part rust protection. The recall began September 11, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U27.
