Volvo S80 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Volvo S80

Volvo S80 Problems

Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.

Many complaints have been reported regarding Volvo S80 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 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.

Volvo S80 Recalls

A software error within the Central Electronic Module (CEM) will result in the "TPMS Service Required" message appearing after approximately 15 minutes of accumulated driving over 25 mph. The error will prevent the TPMS from warning the driver that a tire needs air. Underinflated tires can result in tire overloading and overheating, which could lead to a blowout and possible crash. Dealers will reprogram the CEM to correct this concern. The Volvo recall number is 256.

A computer software error may prevent the transmission from downshifting, such as shifting from fifth to fourth gear when coasting. This can result in decreased engine RPMs and possible engine stall, increasing the risk of a crash. Dealers will upgrade the software to the transmission control module to correct this concern. The Volvo recall number is 255.

The wire harness under the front seats may not have been secured properly to the seat frame. As a result, when the seats are moved to adjust the seating position, the wire harness may be pulled, causing it to disconnect. In the event of a crash, the front and/or side impact airbags may deploy improperly or not at all, increasing the risk of personal injury. Also, the lap belt pretensioner may not deploy. Dealers will inspect and secure the affected harness as necessary to correct this concern. The Volvo recall number is 250.

Purchased a 2000 Volvo S80 used from a friend of a friend. Sharp-looking car with a generally smooth and comfortable ride. Thanks to meticulous maintenance by the previous owner and myself, the car runs relatively well. Have however experienced problems with exterior trim pieces (side markers, moldings, weather stripping, gas door) breaking or coming loose. These have been generally simple repa...

very nice car I purchased it two yrs. ago at 145,000 miles but recently been having transmission shifting issues. the car seems to not want to shift to second gear rpm just goes up but no acceleration. I had the tranny flushed and filter changed but it still slips. I took it to a transmission shop but they couldn't diagnose the problem because it's intermittent. It slips on the way to the shop ...

Best car I ever had. Had it for 3 years and starts up every time and has a nice smooth ride. Haven't had to put a lot of money in it either.
