2006 Mercury Grand Marquis Problems

Intake Manifold May Crack Leaking Coolant Behind the Alternator

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

Transmission Failure 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.

Throttle Position Sensors May Fail and Cause Engine Performance Problems

The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.

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. If the steering column lower bearing has separated, a retainer clip will be installed.

Additionally, Vehicle owners located where salt is not used who have concerns regarding their steering will have a one-time option to have their vehicles inspected and, if necessary, repaired.
