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!

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.

Knocking noises going over bumps can be caused by worn sway bar end links. These end links have small ball joints that become loose and rattle. Replacement is the only fix.

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 replace them. It cost me $5,500 from the dealership. The repair shops were about the same price for the replacement.
After 5 years, the cloth top is about ready for replacement.
I cannot recommend this vehicle.
