Are transmission problems common on 2004 XC90 models with 6 Cylinder Turbo?

yes the xc90 all have transmission problems. I bought a 2004 just 3 weeks ago. It has 107000 mil. the transmission went out a week after I bought it. I paid 2750.00 to rebuild it. My guy has had it for three week and can not get it fixed.

Yes, these do have automatic transmission failure issues, and if that message is appearing you may be looking at a new transmission.

Yes, they have problems with the transmission and if you pressure the dealer the factory will replace it for free. I did it that way. Good luck.
