A broken vacuum hose near the power steering pump deteriorates and can cause a rough idle and the Check Engine Light to illuminate

The AC evaporator is prone to leaking, causing the air conditioning system to lose refrigerant and stop blowing cold air.

The MAF sensor is prone to failure and will turn on the Check Engine Light when it fails.

One or both of the front wheel bearings may fail resulting in a rumbling noise from the front wheel area when driving over 25 mph.

 

There are several common complaints regarding Volvo V70 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation to name a few.

If the issue is minor, a transmission software update may address this. If available, the software should be updated before any repairs are made. After a software update or repair, the shift adaptation needs to be reset. A good quality Volvo repair shop will know how to perform this task.

There are several technical service bulletins (TSB's) available from Volvo that address these shifting issues and they should be consulted by the repair shop during the automatic transmission diagnostic process.

Regular servicing of the transmission fluid can help with preventing transmission failure, but not in all cases. Follow the suggested fluid replacement interval recommended by Volvo. You will find this in your owners manual, or find it here>>

The anti-lock brake system (ABS) warning light and/or other dash warning lights may illuminate due to a failed ABS Control Module. Replacement of the failed module is generally required to correct this concern.

The anti-lock brake system (ABS) warning light and/or other dash warning lights may illuminate due to a failed ABS Control Module. Replacement of the failed module is generally required to correct this concern.

The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

The front control arm bushings wear out, resulting in alignment issues and squeaking and/or knocking noises from the front end. Worn bushings will require replacement.

One or more door lock assembly may fail and cause door locking/unlocking problems.

The Electronic Throttle Module (ETM) has a higher than normal failure rate. Volvo has extended the warranty on some of the ETMs to 10 years/200,000 miles

The secondary air pump may fail causing the check engine light to illuminate. The cause is often a failure of the air pump check valve that contaminates the air pump with exhaust gas/moisture.

When braking at highway speeds or when descending hills, a rumbling or vibration felt throughout the vehicle can be from the rear brake rotors. Replacement of the rear pads and rotors is the fix, and make sure that the shop installs the special cut-out shims available from Volvo to help prevent this in the future.

A refrigerant leak may develop from the AC evaporator causing the AC to blow warm air. Verifying failure of this component is difficult. A good shop will use leak detection dye to verify a failing evaporator.

An abnormal vibration maybe noted due to a worn upper and/or right front engine mount. Replacing all worn mounts may be necessary to correct this concern.
