DEALER WILL REPLACE THE DIPSTICK AT NO CHARGE.
Defect
THERE MAY BE A MALFUNCTION OF THE WINDSHIELD WASHER PUMP DUE TO ITS POSITION IN THE ENGINE BAY.
Remedy

Defect
THE EXHAUST GAS RECIRCULATION MANIFOLD CORE PLUGS MAY BECOME DISPLACED RESULTING IN A LOSS OF ENGINE VACUUM AND SUBSEQUENT STALLING. THIS WOULD PRODUCE IMMEDIATE ERRATIC ENGINE OPERATION AND SUBSEQUENT LOSS OF POWER BRAKES AND POWER STEERING ASSIST.
Remedy
DEALER WILL INSTALL A MODIFIED CORE PLUG DEVICE AT NO COST TO OWNER.
