2009 Mercury Mariner Hybrid Problems
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.
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.
