Electrical Equipment problems of the 2003 Volvo S60

The grief from this car literally began on the way home from the show room, as the seat belts were not functioning. They required four visits to the service department to correct the problem. The issue of the tires being unsafe became apparent when the car was two weeks old, with under 1000 miles on the odometer front & rear bumpers separate from vehicle , with little or no provocation. Tires self destruct at speeds of 2-4 mph (while parking), if a curb is touched. I'm informed that tires have weak sidewalls & to replace tires (at my expense). Air conditioning required three visits to repair shop & is still not getting the car as cold as it should in hot weather. I should add that I'm also informed that replacement tires will diminish the handling of the car.
