Known Problems

2.0L engines may become low on engine coolant with no cause found for the coolant loss. Our technicians tell us than in some cases the engine block may require replacement due to porosity.

The thermo contact in the AC compressor can fail, which means the compressor may fail to engage or disengage.

The shaft for the air blend door can fail creating the inability to adjust the AC or heating temperature. The AC or Heat will not maintain the proper temperature.

The Check Engine Light may illuminate because of oxygen sensor failure. There may be no drivability symptoms detected though gas mileage may suffer.

 

The anti-lock brake system (ABS) and/or traction control light may illuminate. This can be caused by corrosion in the (ABS) wire harness connector at the right front wheel speed sensor due to water intrusion.  Corroded connectors should be cleaned or replaced as necessary to correct this concern.

The air blend system in the heating, ventilation and AC (HVAC) system can have problems, which can cause the AC controls to be stiff, or a lack of HVAC control.

The AC evaporator can leak causing poor cooling of the air conditioning. The loss of refrigerant may be hard to diagnose.

The Check Engine Light may come on because the electronic throttle body has failed. Other symptoms include loss of acceleration, a high idle or failure to return to idle, and difficulty starting.

Oil leaks from the timing cover, valve cover, and/or rear main seal may be due to excessive crankcase pressure. An updated PCV (Positive Crankcase Ventilation) kit was released to fix this concern.

The Check Engine Light may illuminate because of air injection pump, and/or check valve failure. There may be no drivability symptoms detected.

If the engine will crank but not start, it may be the fuel pump has failed. Diagnosis may find no fuel pressure when attempting to start the engine.

The exhaust flex pipe can fail causing excessive exhaust noise from the front/center area of the vehicle. The flex pipe is a flexible joint in the exhaust that allows for engine movement.

The third brake light and/or license plate lamp may fail due to wiring damaged from rubbing on the trunk lid handle. Our technicians tell us the repair involves correcting the damaged wiring and isolating the connectors so they do not contact the trunk lid handle.
