RepairPal has identified the most common problems for 25 Volvo models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
There have been problems with the climate control system not working at times. Volvo has made a Software upgrade for the AC control module is available that can correct certain climate control system faults.
Problems with the audio system have been reported. There are software upgrades available that will address certain issues. Problems unrelated to software issues will require standard repair procedures.
The convertible top may have problems with the micro-switches and potentiometers that help control the raising and lowering of the top.
It's quite common for the the fuel pump to fail, causing a no start condition. The engine will crank over but it will not start.
To verify this the fuel pressure and electrical power to the fuel pump should be checked. If the pump is getting power and there's no pressure, replace the pump. If it isn't getting power, check the fuel pump relay circuit.
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
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 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 right front engine mount wears out prematurely, causing engine vibration at idle.
The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.
Other symptoms may include an illuminated Check Engine and transmission shift light. and the speedometer may stop working as well.
Note: The brake system will operate normally however during a panic stop the Anti Lock Brakes will not work and the wheels may lock-up, causing a lack of vehicle control under these situations.
The automatic transmission may develop shifting problems and/or the Check Engine Light may illuminate due to internal component failure and/or software issues. It is always best to be sure the transmission control module has the latest software installed when any major transmission repair is performed.
