WHEELS
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 17 INCH CHROME WHEELS, THE CHROME WHEELS WERE NOT HEAT-TREATED. THESE WHEELS MAY CRACK AT THE LUG-NUT HOLES, WHICH COULD RESULT IN THE LOSS OF THE LUG-NUT TORQUE.
IF THIS CONDITION OCCURS, THE DRIVER MAY EXPERIENCE NOISE AND/OR VIBRATION WHILE DRIVING THE VEHICLE. CONTINUED OPERATION OF THE VEHICLE COULD RESULT IN THE WHEEL SEPARATING FROM THE HUB, INCREASING THE RISK OF A CRASH.
DEALERS WILL INSPECT THE WHEELS TO MAKE SURE THAT ALL THE WHEELS HAVE BEEN HEAT-TREATED. ANY WHEEL THAT HAS NOT BEEN HEAT-TREATED WILL BE REPLACED. OWNER NOTIFICATION BEGAN APRIL 14, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT LINCOLN AT 1-800-521-4140.
