2005 Volvo XC90 T6 AWD L6-2.9L Bi-turbo B6294T from North America
A nice SUV plagued by mechanical issues
Leaking Sunroof at 15,000 miles.
1st Transmission at 36,000 miles.
2nd Transmission at 50,000 miles.
Engine Mount at 40,000 miles.
Steering Rack and sway bar endlinks at 55,000 miles.
Several interior plastic parts have been replaced because they have cracked or broken.
The XC90 is a relatively safe and comfortable vehicle that is plagued by poor design choices.
The exterior flows smoothly and is typical design scheme of Volvo P2 based vehicles.
The interior look standard, however the controls are laid out well and are easy to reach. Interior plastics are of poor quality and they break easily under normal use.
Mechanically this vehicle is a disaster. While the Twin Turbo Inline six is a solid engine, the transmission it is mated to was a poor choice. Volvo decided to use a General Motors 4 speed automatic (4T65AWD). This transmission has proven troublesome, regularly failing in many units due to a combination of poor quality parts, excessive vehicle weight, and all wheel drive equipment being fitted onto a transmission designed for front wheel drive use only.
The rack and pinion seems to be a trouble spot as well, wearing prematurely and resulting in a noticeable 'clunk,' especially when turning while in reverse gear (i.e. backing out of your driveway in the morning).
Would you buy another car from this manufacturer? No

We have a 2005 model and have had very similar problems. Now with 96k of miles on it I'm worried about what will be next. My biggest concern is the twin turbo... has anyone had any problems with the twin turbo, and if so what is the cost?

All the transmissions on the twin-turbo 2.9 T6 model sold from 2003-2005 will fail from 40000 to 70000 miles. Replacement transmissions last even less, less than 50000 miles. These transmissions were not designed for the twin turbo engine. Even female drivers who drive their cars very gently had their transmission failed at less than 70000 miles.
