My XC-90 has had very unusual problems, so the dealer informs me. One month out of warranty, the rear bearings needed to be replaced. The headlight covers are pitted and dis colored. The wheel nuts had to be replaced twice. The first time for rust the second time for wear???? The very last repair and most upsetting was for a new infotainment module. The problem began when the radio began looking like a disco. The lights began flashing and periodically the radio would shut off and the display would go blank. I can live without the radio, but when this problem corrupted the Air bag system to the point it might not work, I had to have it fixed at a cost of$1350.00 Volvo would do nothing
Larger rear wheel bearings to handle the load of this vehicle. They seem to be too small to handle the load. Better chrome plating on the wheel bolts, to eliminate the rust and stroger bolts to reduce the wear. Lastly,a Heat sink for the module as the heat generated caused the module to fail.
