NHTSA Complaint #10532478 — 2009 INFINITI G37

WHEN ENGINE IS STARTED IT OCCASIONALLY REVS TO 4000-5000 RPM AND REMAINS THERE FOR ABOUT 5-7 SECONDS BEFORE SLOWING DOWN TO A NORMAL IDLE SPEED. THE OCCURRENCES ARE BECOMING MORE FREQUENT. WHEN ACTING NORMALLY, THE ENGINE STARTS AND REVS TO ABOUT 2000 RPM AND THEN SLOWS TO IDLE SPEED IN ABOUT 1-2 SECONDS. THE DANGER OF THE HIGH REVS FOR 5-7 SECONDS IS THAT IF THE DRIVER IS NOT FULLY AWARE OF THE ENGINE'S SPEED, HE COULD SHIFT THE CAR INTO GEAR AND THE CAR WOULD ACCELERATE, PERHAPS HITTING NEARBY CARS, HOUSE, OUT THE GARAGE DOOR, ETC. I HAD SUCH AN INCIDENT AND WAS BARELY ABLE TO HOLD THE CAR IN PLACE WITH FULL FORCE ON THE BRAKES. THE DEALER HAS STATED THAT HE IS UNAWARE OF ANY SERVICE BULLETINS CONCERNING THIS ISSUE, BUT IF I WOULD BRING IT IN, THEY WOULD CHECK THE SETTINGS ON THE ENGINE CONTROL. IN MY OPINION, THIS IS A VERY SERIOUS SITUATION AKIN TO THE TOYOTA UNEXPECTED ACCELERATION PROBLEM AND INFINTI NEEDS TO DEVELOP FIRST AN ACKNOWLEDGMENT OF THE PROBLEM AND THEN A SOLUTION. *TR
