NHTSA Complaint #10626583 — 2009 INFINITI G37

ON A COLD SNOWY EVENING WHILE DRIVING ON THE HIGHWAY AT ABOUT 60MPH THE CAR BEGAN TO VIOLENTLY SHAKE, WHEN I TOOK MY FOOT OFF THE GAS PEDAL THE CAR STOPPED SHAKING, WHEN I TRIED TO ACCELERATE THE CAR AGAIN BEGAN TO SHAKE VIOLENTLY. FORTUNATELY I WAS ABOUT 5 MILES AWAY FROM MY DESTINATION AND MANAGED TO DRIVE ABOUT 25 ON A HIGHWAY. AFTER I REACHED MY DESTINATION I POWERED OFF THE CAR AND LET IT SIT FOR ABOUT 5 MINUTES, THEN I POWERED IT ON AGAIN AND TRIED TO ACCELERATE ABOVE 30MPH WHICH CAUSED THE CAR TO SHAKE AGAIN. I ENDED UP GETTING THE CAR TOWED TO THE DEALERSHIP, WHEN I GOT A CALL BACK FROM THE DEALERSHIP THE NEXT DAY, THE MECHANIC SAID THAT THE PROBLEM WAS DUE TO A SOFTWARE ISSUE WITH THE CAR. DURING THE COLD WEATHER THE AIR INTAKE WAS NOT TAKING IN AIR CORRECTLY WHICH WAS CAUSING THE ENGINE TO MISFIRE. I WAS A BIT SKEPTICAL ABOUT WHAT HAPPENED BUT SINCE THEN I HAVE NOT HAD THE ISSUE OCCUR AGAIN. INFINITI SHOULD MAKE THIS INFORMATION KNOWN TO OWNERS EITHER THROUGH A RECALL OR UPDATE THE SOFTWARE DURING ROUTINE MAINTENANCE. *TR
