2018 Ford Expedition, 2017–2018 Ford F-150, 2018 Ford Mustang and 1 other model Recall: A roll pin may not have been installed in the transmission, potentially…

The defect

Ford Motor Company (Ford) is recalling certain 2017-2018 Ford F-150 and 2018 Ford Expedition and Mustang and Lincoln Navigator vehicles equipped with 10-speed automatic transmissions. A roll pin may not have been installed in the transmission, potentially causing a loss of the "Park" function.

The risk

Despite the transmission shift lever being placed in 'Park' and the instrument panel display indicating 'Park,' the vehicle may roll away after it has been exited if the parking brake has not been applied, increasing the risk of injury or a crash.

The fix — what to do

Ford will notify owners, and dealers will inspect the transmission to make sure it has the roll pin, installing one if it is missing, free of charge. The recall began on April 13, 2018. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 18S09.

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.
