MY CAR WAS BUMPED IN THE RIGHT REAR BUMPER IN A PARKING LOT. THE OTHER VEHICLE WAS NOT TRAVELING MORE THAN 3 MPH. IT LEFT A SMALL LINE OF WHITE PAINT ON THE BUMPER BUT THE BUMPER WAS UNDAMAGED. THE BLIND SPOT SENSOR MALFUNCTION LIGHT CAME ON. I TOOK THE CAR TO THE DEALERSHIP FOR REPAIR. THE DEALERSHIP QUOTED $670 FOR THE SENSOR PLUS $300 FOR LABOR. I CONFIRMED THE PRICE OF THE PART WITH MAZDA USA. THIS VEHICLE HAS A SERIOUS DESIGN DEFECT IF IT CAN'T WITHSTAND A 3 MPH IMPART WITHOUT CAUSING $1,000 IN DAMANGE. MAZDA USA IS USING ITS MONOPOLY ON SUPPLYING PARTS TO GOUGE CONSUMERS. THE WHOLESALE COST OF THE PART TO MAZDA CAN'T BE MORE THAN $50. MY ONLY CHOICE IS TO PAY THE OUTRAGEOUS COST OR DRIVE MY VEHICLE WITHOUT ONE OF ITS SAFETY FEATURES.
