Supports within the roof liner may be insecurely attached.
As a result, the support may separate from the roof liner and fall into the passenger compartment, increasing the risk of injury during a crash necessitating the deployment of the head airbag.
What to do
Dealers will inspect and repair or replace the roof liner -- as necessary -- free of charge.
Owner notification letters are expected to be mailed July 5, 2021.
