## What is wrong

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.


## What can happen

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 remedy

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.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.safercar.gov.
