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 Questions
The noise I hear at most all times sounds IDENTICAL to a car horn being muffled by insulation or towels. Seems to be coming from the firewall side of the engine/compartment.
Thanks and sorry for repeat question.
clock time changes every time I start the car; can't control the levels on the heat and air conditioning, miles driven once reset keeps changing once I stop and start car; radio will just bounce from channel to channel without me changing it
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.
Volvo S80 Reviews
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...
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.
I thought buying the new S80 would be a good idea, and I was wrong. I bought the T-6 the first year it came out and had many problems. Check engine light, bulbs that constantly burn out, and oil leaks to name a few. It was a nice car to drive when all was working, but it had too many problems. I heard they fixed many of the problems after a couple years, but stay away from the 1999 model!
