NHTSA Complaint #10897785 — 2007 LEXUS RX350

I PURCHASED A USED 2007 LEXUS RX 350 FROM CARMAX IN SEPTEMBER OF 2014. THE CAR HAS BEEN AT THE LEXUS DEALERSHIP 4 TIMES ALREADY FOR RATTLE IN BACK OF CAR, IGNITION SWITCH REPLACEMENT, OXYGEN SENSOR REPLACEMENT AND 80,000 MILE SERVICE. THIS MONTH (AUGUST 2016) THE CARE BEGAN TO MAKE A RATTLE JUST AFTER STARTING THE ENGINE. UPON CONTACTING MY LOCAL LEXUS DEALERSHIP, I WAS TOLD THAT THE SOUND I AM HEARING IS THE VVT GEAR WHICH WILL NEED REPLACING. THE ESTIMATE GIVEN TO ME WAS $4K. WHAT MAKES THIS EVEN MORE INTERESTING IS THAT MY HUSBAND OWNS A 2009 TOYOTA HIGHLANDER. HIS VEHICLE MAKES THE EXACT SAME NOISE UPON STARTING THE ENGINE. HE TOO WAS TOLD THAT HE NEEDED THE VVT GEAR REPLACED FOR A COST OF $6K WHICH WAS ONLY THE LABOR PORTION. AFTER READING COMPLAINTS WITH THE 2007 LEXUS RX 350 AND KNOWING THAT LEXUS ISSUED A RECALL ON CERTAIN 2008 LEXUS MODELS FOR THIS VERY ISSUE TELLS ME THAT A NEW RECALL SHOULD BE MADE BEFORE SOMEONE IS INJURED OR DEATH OCCURS. VERY DISAPPOINTED IN LEXUS.
