The contact owns a 2015 Infiniti QX50. The contact stated while driving at an undisclosed speed, there was an abnormal sound coming from underneath the vehicle. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The vehicle was then taken to an independent mechanic, who confirmed the diagnosis. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 46,000.
TL* THE CONTACT OWNS A 2015 INFINITI QX50. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE AUTO DIMMING FEATURE WAS FRACTURED CAUSING IT TO BE VERY DIFFICULT TO SEE AT NIGHT. THE FAILURE OCCURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE AUTO DIMMING SWITCH NEEDED TO REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE OCCURRED MULTIPLE TIMES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 78. THE VIN WAS NOT AVAILABLE.
THE CAR STARTED NORMALLY AND AFTER DRIVING ABOUT A QUARTER OF A MILE I WAS SUDDENLY COASTING WITHOUT POWER. THE ENGINE JUST QUIT. WITHOUT POWER STEERING AND BRAKES I WAS STILL ABLE TO GUIDE IT TO THE CURB AND COME TO A SAFE STOP. WHAT I ATTEMPTED TO RESTART THE CAR IT ACTED AS IF THE BATTERY DIDN'T HAVE ENOUGH POWER TO TURN OVER THE ENGINE, ALTHOUGH LIGHTS, HORN AND RADIO STILL WORKED FINE. THE CAR WAS TOWED TO THE DEALER WHERE I BOUGHT IT AND AFTER WEEK OF UNSUCCESSFUL TROUBLESHOOTING THE INFINITI REPS GOT INVOLVED. WHEN THE OIL PAN WAS REMOVED THEY FOUND NUMEROUS PIECES OF METAL OF VARYING SIZES AS IF SOMETHING IN THE ENGINE HAD DISINTEGRATED. IF THEY KNOW WHAT CAUSED IT THEY HAVEN;T TOLD ME, AND I SINCE I HAD LEASED IT JUST TWO WEEKS PRIOR I'VE ASKED FOR A NEW VEHICLE RATHER THAN TO HAVE THE ENGINE IN THIS ONE REPLACED. AS OF TODAY, NEARLY 2 WEEKS AFTER THE INCIDENT, I AM STILL AWAITING A DECISION. LUCKILY I WAS ON A SIDE STREET WHEN THIS OCCURRED. HAD IT HAPPENED MINUTES LATER I WOULD HAVE BEEN ON A HIGH SPEED MULTI-LANE INTERSTATE HIGHWAY AND THE RESULTS COULD HAVE BEEN CATASTROPHIC. *TR
