2004 Volvo C70 Problems

Convertible Tops May Have Problems With Micro-Switches/Potentiometers

The convertible top may have problems with the micro-switches and potentiometers that help control the raising and lowering of the top.

Hard shifting from transmission and other issues

Several complaints have been reported regarding Volvo C70 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

Door Window Regulator May Fail

Door window regulator failures have been reported. These vehicles have a very complex door window mechanism that can be very difficult to adjust properly after installing a new window regulator. This can lead to air leaks, wind noise, and a door that doesn't open or close properly. This is a good time to find an experienced Volvo mechanic!

2004 Volvo C70 Reviews

Love this car. It's a pleasure to drive and has been very reliable. I bought an extended warranty but it turned out to be a waste of money since I only had a $100 repair during the 3 years of warranty.
The convertible is great, but the car does not have a lot of bells and whistles. The interior is pretty plain, and the dashboard is basic. The upgraded sound system is fantastic. Maaintenance has been fine with the exception of the transmission needing to be replace at 69K miles. THis si terrible for a 5 year old car. Volvo, or repair shops, don't repair Volvo transmissions. They only rep...
My daughter bought a 2004 C70 from a co-worker. It ran great for about a year and then the transmission had to be repaired, the ac stopped working, the rag top will no longer open or close, this all happened within about three months. Now the lights aren't working properly. Will never buy another Volvo.
