Consumer Description

I WISH TO FILE A COMPLAINT ABOUT A BRAKE FLUID LEAK FROM THE MASTER CYLINDER INTO THE VACUUM BOOSTER. ON THIS DATE, THE BRAKE WARNING LIGHT TURNED ON. I INSPECTED THE MASTER CYLINDER AND NOTICED THAT FLUID WAS AT THE MINIMUM LEVEL. I PURCHASED BRAKE FLUID AND FILLED THE RESERVOIR. WHEN I TOOK THE CAR IN FOR A ROUTINE OIL CHANGE TODAY (JANUARY 5, 2012, I TOLD THE DEALER WHAT I HAD DONE. THEY INSPECTED THE CAR AND FOUND THE MASTER CYLINDER WAS LEAKING BRAKE FLUID INTO THE VACUUM BOOSTER DUE TO A FAULTY O-RING. THE WORK WAS COVERED BY MY WARRANTY. HOWEVER, BECAUSE IT IS UNUSUAL FOR A MASTER CYLINDER TO FAIL WITH SO FEW MILES ON THE CAR, I CHECKED ON THE INTERNET AND FOUND THAT A NUMBER OF OTHER ALTIMA OWNERS HAVE EXPERIENCED THIS PROBLEM, AND I AM CONCERNED THAT THERE MAY BE A SAFETY ISSUE BREWING. I UNDERSTAND THAT THE NHTSA IN MAY 2011 WAS PLANNING TO INVESTIGATE SIMILAR PROBLEMS IN 2007-08 ALTIMAS. IT APPEARS THE PROBLEM MAY BE IN 2009 ATIMAS ALSO. *TR
