Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- Rear bumper system on certain vehicles may not have been properly welded during assembly. In the event of a rear end collision, the right side bumper supportor could break loose, damage the fuel tank and allow fuel to leak.
- The fix
- A reinforcement plate will be installed, if necessary, to prevent fuel tank damage. Work will be performed at no cost to owners.
- The problem
- On certain vehicles, porous spots may have developed on the interior surface of the threaded hole for the brake hose during the moulding process. These spots allow brake fluid to seep from the calipers during heavy brake applications.
- The fix
- Both front brake calipers will be inspected for brake fluid seepage and will be replaced, if necessary, without charge.
