2008 INFINITI M45 Steering Problems

WHILE DRIVING EAST (UPHILL) ON I-90 FROM SEATTLE TOWARD SNOQUALMIE PASS, MY CAR SUDDENLY AND UNEXPECTEDLY VEERED INTO THE ADJACENT LANE, LITERALLY TEARING/TURNING THE STEERING WHEEL OUT OF MY HANDS. I PULLED OFF THE FREEWAY TO LET MY HEART RATE SLOW DOWN. ON MY RETURN TRIP, DOWNHILL, THE SAME TERRIFYING EXPERIENCE OCCURRED, NARROWLY AVOIDING A COLLISION WITH A TRUCK. A BIT OF INTERNET RESEARCH REVEALED THAT THIS EXPERIENCE IS CALLED "TRAMLINING" AND THAT MANY INFINITI MODELS/YEARS HAVE BEEN REPORTED TO SUFFER FROM IT. I REPORTED MY EXPERIENCES TO MY LOCAL INFINITI DEALER'S SERVICE MANAGER, BUT HE ACTED BAFFLED BY THE TERM "TRAMLINING" AND TOLD ME, "AFTER ALL, YOU OWN A 45S, A SPORT MODEL." HE CHARGED ME A BUNDLE TO PUT NEW TIRES ON MY CAR, BUT THE TRAMLINING PROBLEM HASN'T GONE AWAY -- ONLY MY MONEY. *TR
