RepairPal Expert Overview:
In areas where salt is used on the roads, slush containing road salt can splash through a gap in the fuel tank protector resulting in corrosion of the brake lines. This corrosion may lead to brake fluid leakage resulting in reduced braking performance, increasing the risk of a crash. Dealers will inspect the affected vehicles and leaking brake lines will be replaced. Anti-corrosion rustproofing wax will be applied to all recalled vehicles.

It seems like the Subaru cars don't really need the big repairs until after 100K which is the maximum service contract I could get. Is it worth getting that contract? They want $1,800 for mine.
