NHTSA Complaint #10210267 — 2006 NISSAN ALTIMA

I BOUGHT A 2006 NISSAN ALTIMA IN NOVEMBER OF 2005. I HAVE NOW HAD THIS VEHICLE FOR 2 YEARS. I JUST CAME ACROSS 2 RECALLS ONLINE BY ACCIDENT. I WAS NEVER NOTIFIED OF THESE RECALLS AND THEY BOTH APPEAR TO BE VERY SERIOUS. 1- (#06V223000) FROM JUNE 2006 INVOLVING "ENGINE AND ENGINE COOLING" THAT LISTS EXCESSIVE OIL CONSUMPTION AND POSSIBLY ENGINE FIRE AND 2- (06V0046000) FROM FEB. 2006 INVOLVING REAR SUSPENSION AND POSSIBLY A CRACKED BRACKET. I HAVE HAD TO ADD PLENTY OF OIL SINCE BUYING THIS CAR, BUT CANNOT BELIEVE I WAS NEVER NOTIFIED ABOUT A SERIOUS AND POTENTIALLY DANGEROUS SAFETY HAZARD AS THIS, NOT TO MENTION THE DAMAGE IT MUST HAVE ALREADY CAUSED TO THE ENGINE!! WHAT DO I DO NOW AND WHAT CAN BE DONE TO THIS OBVIOUS TERRIBLE SHADY DEALERSHIP AND UNFORGIVABLE MANUFACTURER?? *TR
