2017 Infiniti QX50 Body & Structure Problems

SENSOR ON MY HANDLE AND THE KEY QUIT WORKING OVER THIS PAST YEAR MY CAR HAS BEEN AT THE SERVICE DEPARTMENT FOR DAYS AND WEEKS AT A TIME FOR THE SAME ISSUE DEALERSHIP HAS CHECK ALL SETTING THEY HAVE CHANGED THE BATTER THREE TIMES IN THE CAR AND TWICE IN THEY HAVE CHANGED THE BATTERY IN THE REMOTE , I'M NOW TOLD THAT THEY JUST CHANGED THE DOOR HANDLE AND WAS TOLD THERE IS NOTHING THEY CAN DO ABOUT IT, AND WAS ASKED TO PICK UP THE CAR , I STRESSED THAT I WILL BE OUT OF WARRANTY AND I DON'T WANT TO HAVE THIS SAME PROBLEM HEN ITS EXPIRED OR TRANSFER OR SELL TO SOMEONE ELSE TO INHERIT THIS ISSUE. PLEASE NOTE ,THE PUSH BUTTON ON THE HANDLE DO NOT WORK ON THE PASSENGER SIDE, AND THE PUSH BUTTON DO NOT WORK ON THE HANDLE ON THE DRIVER SIDE THIS WOULD HAPPEN RANDOMLY EACH TIME I HAVE TAKEN MY CAR QX50 TO THE DEALER FOR SERVICE ATTENTION I WAS TOLD THEY WILL NEED TO SEE THE ISSUE SO I PROVIDED THEM WITH THE VIDEO , THIS LAST TIME THEY SEEN IT THEMSELVES AND DECIDED TO HOLD ONTO THE FOR FURTHER RESEARCH , THIS IS WHEN I WAS ASKED TO PICK UP THE CAR IN ITS CONDITION. THEY CANNOT SAY WHY HANDLE SENSOR AND LOCK QUIT WORKING EVEN AFTER RUNNING DIAGNOSTICS. MY GUESS IS THAT SINCE BOTH SIDES AREN'T WORKING, IT IS UNLIKELY THAT THE PROBLEM IS WITH THE SENSOR AS BOTH SIDES WOULD HAVE HAD TO FAIL AT THE SAME TIME EACH TIME. *LN*JB
