What can fail
The battery cable to the alternator is routed incorrectly and not tightened enough. It can rub against the power steering line, wearing through its insulation and causing an electrical short.
What the fix does
The dealer will inspect the cable for damage and replace it if needed. The cable routing will be corrected, a clip added to secure it, and the alternator attachment will be tightened to specification.
