The contact owns a 2012 Infiniti G37. The contact stated while starting the vehicle, the vehicle burst into flames in the front area of the vehicle. As a result, the front of the vehicle was severely burned and two parked vehicles nearby were damaged due to the fire. The fire department was able to extinguish the fire on all the vehicles. The contact did not suffer any injuries. A police report was filed. The vehicle was not diagnosed. The manufacturer was not notified of the failure. The failure mileage was unknown.

THE COOLING SYSTEM IN THIS VEHICLE HAS A TWO PART PERFORMED HOSE THAT CONNECTS THE ENGINE COOLING SYSTEM TO THE CABIN HEAT EXCHANGER. THE TWO PARTS ARE CONNECTED WITH A PLASTIC JUNCTION WITH TWO SPRING CLAMPS. THIS VEHICLE HAS APPROX 85K MILES AND STILL HAS THE ORIGINAL COOLANT. THIS JUNCTION DISINTEGRATED. IT APPEARS TO NOT BE COMPATIBLE WITH THE COOLANT. IT DELAMINATED AND SHEARED. LUCKILY IT BROKE WHILE STOPPED IN THE GARAGE. IF IT HAD HAPPENED AT HIGH SPEED IT WOULD HAVE SPEWED THE COOLANT AT THE REAR OF THE ENGINE, AND AT LEAST SOME OF IT WOULD HAVE GONE TO THE WINDSHIELD, OBSTRUCTING THE VIEW. I HAVE SAVED THE DISINTEGRATED PART.*DT*JB

THE VEHICLE WAS IN MOTION AND WOULD NOT ENTER 3RD OR 4TH GEAR. WHEN I BROUGHT IT INTO THE RETAILER THEY SAID I NEEDED TRANSMISSION VALVE BODY REPLACED AT A COST OF $3000. THE CAR ONLY HAS 55,000 MILES ON IT. WHAT WOULD CAUSE THIS?

STOPPED AT A TRAFFIC LIGHT. CAR IN DRIVE & FOOT ON BRAKE PEDAL. ENGINE SUDDENLY REVS UP TO OVER 3000 RMP AND CAR WANTS TO LUNGE FORWARD.VERY DIFFICULT TO HOLD CAR FROM LUNGING INTO CAR IN FRONT.
