2009 Mercury Grand Marquis Problems

Malfunctioning Headlights

The car had 64600 miles on it and the headlights started going out while driving, which can be very dangerous. The problem is in the Light Control Module which is an expensive part (around $500 to $600 + labor).

Transmission Problems Common Due to Front Pump Failure

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

Engine May Overheat at Idle With AC On

The engine may overheat at idle when the AC is on. A new, upgraded fan motor and resistor may be required to correct this concern.

Dealers will replace the lower intermediate steering shaft and inspect the upper intermediate shaft and steering column lower bearing for damage, they will be repaired or replaced as necessary.
