Stripped Threads
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
If internal (mating component) threads or external (fastener) threads appear stripped or galled, replace both fastener and mating component. When tightening, if minimum torque is not reached, internal threads on mating component may have stripped. Remove the fastener to inspect and replace mating component if stripped threads are found.
