## What is wrong

Ford Motor Company \(Ford\) is recalling certain 2020 Lincoln Aviator and Ford Explorer vehicles.  The rear lower control arm \(RLCA\) bolts that attach the rear lower control arms to the wheel knuckles may not have been heat\-treated, which could cause them to break.


## What can happen

Broken RLCA bolts can cause a loss of steering control, and increase the risk of a crash.


## The remedy

Ford will notify owners, and dealers will replace both RLCA bolts, free of charge.  The recall began on April 2, 2021.  Owners may contact Ford customer service at 1\-866\-436\-7332.  Ford's number for this recall is 21S11.
