Known Problems

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

 

The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.

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 clutch in the torque converter can fail, allowing debris to circulate throughout the automatic transmission.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The AC condenser failed due to contact with road debris and a lack of protection for the condenser.

The anti-theft system may fail causing a no start condition, the security light may illuminate. Our technicians tell us that the ignition switch may need to be replaced to correct this fault.

The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.

The high-pressure power steering lines are known to leak.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

Excess cooling fan noise may be caused buy a faulty cooling fan and fan clutch.

A rough idle may be noted after starting the engine cold, along with illumination of the Check Engine Light with code P050D stored. Our technicians tell us the powertrain control module (PCM) software should be upgraded to correct this concern.

The automatic transmission can develop problems like erratic shifting, rough shifting, or delayed gear engagement. Repairs for many of these problems are outlined in service bulletins.

If you experience a harsh downshift from fourth to third gear, the transmission control module (TCM) software should be checked and updated if necessary before any other repairs are performed.

Several issues occur with the door locks on the Volvo C70 and most are because of the door lock assembly. What happens is that one door will not lock while the other one does. In other cases you will lock the doors and then one of the doors will immediately unlock.

The problem is that the door lock assembly is defective and will need replacement. Replacement of this assembly on the C70 is very difficult and is not recommended by a novice. Getting the door and window aligned properly so that you don't get air or water leaks is very, very difficult.

The intake manifold gasket can develop external engine oil or coolant leaks. In some cases the failed gasket will leak coolant internally. The manifold gasket will need to be replaced to correct this issue.

The automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern.

One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.

Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

The instrument panel and switch backlighting may fail due to a faulty dimmer control module. A failed module will require replacement.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
