2003 Lincoln LS Problems

Service power steering fluid regularly

Even though the manufacturer does not call for regular servicing, our technicians recommend servicing the power steering fluid regularly.

Rough Idle and/or Engine Stalling Condition

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

Overheating Due to Damaged Water Pump

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.

17" Chrome Wheels May Loosen and Fall Off

17" chrome wheels may not have been properly heat treated. These wheels may crack at the lug nut holes, which could result in loosening of the lug nuts. The driver may experience vibration and/or abnormal noise while driving. Continued operation of the vehicle could result in the wheel failing off, increasing the risk of a crash. Dealers will inspect the wheels and replace those without proper heat treating. The Ford recall number is 03S01.

I recieved a 03 ls from a customer to do an easy tune-up. but after looking into it found most all easy items changed by previous owner and it still will not drive down road. This is the 3rd ls I have seen like this with a MAJOR problem and hope people stay away from them.
