RepairPal has identified the most common problems with the Ford as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
An engine knocking noise coming from the lower end during acceleration is common and could be caused by worn or damaged engine bearings.
The tachometer sensor may fail; if the tachometer needle jumps around and the transmission has harsh shifts or does not upshift, this sensor should be checked. This sensor is mounted in a cover at the front of the motor.
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.
Engine misfire could be caused by worn or broken motor mounts that raise the motor on one side while the vehicle is accelerating. The stress on the engine control wiring harness can cause breaks in the injector or sensor wires, which then causes drivability concerns such as poor fuel economy and engine misfires.
Bad motor mounts can cause the motor to move excessively, which pulls on the MAP sensor vacumn hose every time you step on the gas pedal. This either weakens the hose so it collapses (causing low vacuum flow) or pulls the vacuum hose that connects the intake manifold to the MAP sensor completely off of the sensor. When the hose is disconnected from the MAP sensor, a full rich condition will result.
Automatic transmission failure is higher than normal in this model. Small metal pieces may be found at the bottom of the transmission oil pan when the transmission is serviced.
