“My headlights stopped working and after I replaced the bulbs, the problem persisted. After further diagnostics, it was determined that my car had a corroded relay junction. It ended up costing almost $2000 to repair. I heard from the mechanic and reports on line that other people have been having the same issue for this make and model so I thought it would be worth reporting.”
