Model Years Affected: 2005, 2006


Corrosion at the fuel tank to body harness may cause the Check Engine Light to illuminate or a crank no start condition. This corrosion issue is most commonly caused by a water leak inside the vehicle. Any damaged wiring or connectors will require replacement.

  • Not sure what mileage was but I kept taking it back to dealer who kept telling me they couldn't reproduce the problem. Then it left me stranded on a busy highway and I had to have it towed. And I was hot they found the problem and replaced fuel tank and all.
