RepairPal has identified the most common problems for 16 Mercury models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.
The exhaust manifold often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold. A ticking type noise may be noted most noticeable when the engine is cold.
Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.
It is not uncommon for the intake manifold and/or valve cover gaskets to develop a coolant or oil leak. Leakage from the intake manifold may result in coolant in the engine oil. Coolant mixing with the engine oil severally impacts the lubrication ability of the oil. Internal engine may result if this condition is not repaired promptly.
The rear window wiper may not fully contact the rear window. To fix, replacement of both the wiper blade and wiper arm is necessary.
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.
The instrument cluster (IC) may reset to its default settings when the ignition is turned off. Our technicians tell us revised IC programing is available which should correct this concern.
The transmission oil cooler may develop a leak, which will require replacement to repair.
The electric trunk latch solenoid can get stuck in the open position making it so the trunk will not latch closed. The diagnosing technician should verify correct electrical connection at the solenoid and check for correct cable routing. The trunk latch most commonly will need to be replaced.
Sludge build up in the throttle body can cause a poor engine idle, stalling, and/or hesitation. The correction is to install a new idle air control valve spacer kit to prevent the sludge build up, set the base idle, and clean the throttle body.
Fitment and abrasion of wheel covers to the wheels can cause the wheel covers to make a ticking and / or clicking noise. Lubricating the back side of the wheel covers where they mate to the wheels should correct this problem.
Faulty material in manufacturing could cause the inside door pull handle to break. Both handles should be replaced.
Fitment and deterioration of weatherstripping on mating surfaces of the convertible top can cause water to leak in the interior. The contour of the roof can also contribute to the leak problems. Foam can be added to bolster the contact points where leaks occur and / or the weatherstrips can be replaced where they are deformed.
If the vehicle hesitates or idles roughly after being parked for twenty to thirty minutes, with the engine still warmed to normal operating temperature, you may need to reprogram the PCM (powertrain control module) with new calibration.
