What is wrong

Chrysler (FCA US LLC) is recalling certain 2018-2019 RAM 1500 trucks. The rear differential may have been insufficiently filled, possibly resulting in its failure.

What can happen

If the rear axle assembly fails, it can cause a loss of drive or the rear wheels may lock up. Either scenario increases the risk of a crash.

The remedy

Chrysler will notify owners, and dealers will inspect the rear axle oil level. Rear axles with an insufficient amount of oil will be replaced, free of charge. The recall began September 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U88.

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.
