Most reported Volvo problems
The steering wheel module (SWM) stops working, this affects the turn signals, horn, cruise control, and audio buttons on the steering wheel.
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.
The transmission overdrive relay often fails, preventing the transmission from shifting into overdrive
Many complaints have been reported regarding Volvo XC70 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation all together to name a few.
If the issue is minor, a transmission software update may address this issue so 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: http://bit.ly/Volvo_Owners_Manuals
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.
One or more door lock assembly may fail and cause door locking/unlocking problems.
There have been reports of premature rear brake pad wear. Our technicians recommend to inspect brake pads at each tire rotation interval.
Oil leaks from the all-wheel drive differential housing have been reported.
The turbocharger return pipe seal may develop an oil leak. The leak can begin very small, but will eventually progress into a large leak. Our technicians recommend having this repaired at first signs of leakage.
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.
Coolant leaking from the front of the vehicle is often due to a leaking radiator, which must be replaced.
