What can fail
Road salt can collect inside the front lower control arms, causing internal rust that thins and may perforate the steel. A severely corroded control arm can fracture, potentially causing loss of vehicle control.
What the fix does
Dealers will inspect the front lower control arms and replace them if needed. If replacement isn't necessary, drainage holes will be added and rust-proofing treatment applied.
