THE LEXUS NX 300 F SPORT HAS BEEN AN EXTREMELY FRIGHTENING EXPERIENCE. THE COLLUSION SYSTEM HAS PLACE MY FAMILY AS WELL AS MYSELF IN IMMEDIATE DANGER TO THE POINT THAT I DO NOT OPERATE THE VEHICLE. THE VEHICLE HAS BRAKED UNEXPECTEDLY ON THE HIGHWAY AND ON BACK ROADS WITH NO ONE IN FRONT OF ME. IT HAS ALMOST CAUSED NUMEROUS ACCIDENTS . WE HAVE HAD THIS LEASE FOR ONE YEAR AND 9 MONTHS AND THE PROBLEM STARTED AT 15,000 MILES AND HAS HAPPENED MORE THAN 7 TIMES MOST IMPORTANTLY IN INCLEMENT WEATHER WHICH COULD HAVE CAUSE A PILE UP ON THE HIGHWAY. WE HAVE SPOKEN TO OUR DESIGNATED LEXUS DEALERSHIP EACH TIME AND BECAUSE THEY CAN NOT DUPLICATE THE ISSUE DURING THEIR DIAGNOSTIC TESTING THEY CONTINUE TO PUSH US AWAY. WE HAVE ALSO REACHED OUT TO THE GENERAL SALES MANAGER AND DUE TO A FAULTY CAR THAT WE WERE GIVEN THEY HAVE BEEN EXTREMELY UNPROFESSIONAL. MY HUSBAND AND I ALSO REACHED OUT TO LEXUS CORPORATE AND THEY STATE THAT ON THE SERVICE DOCUMENTATION NOT ONCE HAVE THEY STATED THAT DIAGNOSTIC TESTING HAS BEEN IMPLEMENTED, WHICH SHOWS THE REGARD FOR OUR SAFETY IS NOT A PRIORITY . MY HUSBAND AND I HAVE TRIED TO WORK THIS ISSUE OUT IN HOUSE, BUT NOW WE HAVE DECIDED TO EXERCISE OUR CONSUMER RIGHTS AS A CUSTOMER. WE ARE EXTREMELY DISSATISFIED AND THIS CAR NEEDS TO BE TAKEN OF THE ROAD AS OUR LIVES HAVE BEEN IN DANGER AND THE VEHICLE IS TRULY UNSAFE.
