2014 Mazda MAZDA5

I bought this vehicle as is, about 2 months past, after driving it home I felt after pressing the Brakes pedal that it is not responding until I press 2 or 3 times. I went bnack to the dealer the next day and made a complain. They sent me to their Mechanic who diagnosed the problem to be the ABS Hydraulic Control Unit Assembly. It is available for inspection upon request. My safety and the safety of my family was put at risk because of the fact that I have to pump the brakes to slow the vehicle. Yes the problem was confirmed by the independent Mechanic recomended by the dealer, with a detailed estimate. No inspection was performed by the manufacturer, police or insurance representatives. The service light was on from the day I bought the vehicle.

The contact owns a 2014 Mazda Mazda5. The contact stated that while driving over a minor bump in the roadway at any rate of speed, the brake pedal would depress to floorboard without warning. The contact stated that the brakes would resume normal operation soon after failure. The contact had taken the vehicle to three separate independent mechanics however, each mechanic was unable to determine the cause of the failure. Neither the dealer nor the manufacturer were made aware of the failure. The vehicle was not yet repaired. The failure mileage was approximately 48,000.

WHEN APPLYING THE BRAKES, THE VEHICLE OFTEN HAS A CLUNKING SOUND AND A SLIGHT / BRIEF HESITATION BEFORE THE BRAKES ENGAGE. THE VEHICLE IS IN MOTION WHEN THIS OCCURS. I'VE HAD THE ISSUE INSPECTED ON MULTIPLE OCCASIONS (4-5 TIMES) AND WAS TOLD THERE IS NOTHING WRONG WITH THE BRAKES. I WAS INFORMED THAT IT IS POSSIBLE THAT IT IS BY DESIGN WHICH IS WHAT LED ME TO SUBMIT THIS REQUEST. THE ISSUE HAPPENS APPROXIMATELY 75-80% OF THE TIME. I DID NOT NOTICE THIS ISSUE WHEN THE VEHICLE WAS PURCHASED (NEW IN JAN, 2015) BUT NOTICED IT APPROXIMATELY 2 YEARS AFTER PURCHASE. SINCE THEN THE ISSUE HAS GRADUALLY INCREASED IN FREQUENCY AND HAPPENS NOT EVERY TIME THE BRAKES ARE USED BUT HAPPENS OFTEN EACH TIME THE VEHICLE IS DRIVEN.THE DATE OF OCCURENCE BELOW DOES NOT APPLY SINCE IT HAPPENS EVERY DAY AND IS STILL OCCURRING. ALSO, THE SPEED AND THE MILEAGE DOESN'T APPLY SINCE IT HAPPENS AT ALL SPEEDS AND HAS HAPPENED REGULARLY SINCE ABOUT 79000 MILES.
