Most Reported Volvo Problem Reports
The electronic throttle module (ETM) has a higher than normal failure rate. There is a possible extended warranty and/or a software upgrade offered by Volvo for this problem.
The fuel pump relay may fail resulting in a "no start" condition, the engine will crank over but will not start and run. Checking for proper fuel pressure would be the first step in diagnosing this concern.
Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.
Coolant leaking from the front of the vehicle is often due to a leaking radiator, which must be replaced.
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
It is not uncommon for the exterior light bulbs to burn out prematurely. No repair option has been reported other than replacing the failed bulb.
The parking brake may be hard to release. Our technicians tell us that adjusting the parking brake cable will generally correct this issue.
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.
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.
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.
Many complaints have been reported regarding Volvo S70 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 fix this issue so if available, the software should be updated before any repairs are made.
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
