Mercury Mariner Hybrid Problems

Coolant Pump on Hybrid May Fail and Cause CEL/Engine Shutdown

The hybrid models have a coolant pump that cools control electronics. The pump can fail or spin slowly, which causes a Check Engine Light to illuminate and complete engine shut down.

Check Engine Light With Code P0442, P0456, and/or P1450

The Check Engine Light may illuminate with code P0442, P0456, and/or P1450. These codes are related to the EVAP system. Our technicians tell us that if no EVAP system faults are confirmed, updated software is available for the powertrain control module (PCM) which should correct this concern.

Hard driving conditions may cause rear motor mount to crack

Hard driving conditions, including quick starts from a stop and hard acceleration up hills, can cause the rear motor mount to crack. The broken motor mount needs to be replaced, otherwise damage to the hybrid drive system may result.

Monday, went to open the car, and neither remote would work. The touch pad on the door also would not work. Opened the door with the key, and the motor would start, but could not get out of park. None of the digital/electronic displays worked. Windows nor locks would work. Air conditioner and cruise did. I was able to drive the car by disabling the "Park/Transmission" lock switch. The de...
The break issue posted above is caused by a faulty speed sensor in the cruise control. Mine was under warranty, but it took them maybe 30 minutes. I had this, and the real tailgate release break. Otherwise no tires, no repairs nothing for 110K miles. It is a great car.
My 2008 Mariner 2WD had to have the computer replaced at about 38,000 miles. It's failure caused the car to quit running on the highway, very dangerious. The good news was the hybrid feature allowed me to get to a dealer and it was covered by the 60,000 mile powertrain warrenty. Now at 59,000 mile the AC compressor failed and had to be replaced (not warrenteed) to the tune of $1,100.00. I a...
