“The plastic oil filter housing was leaking oil onto my exhaust I had to quit driving it because of fear of a FIRE, SO MY QUESTION IS : IF YOU HAVE OIL RUNNING DOWN AND DRIPPING OF YOUR EXHAUST AND YOU GUYS WONT RECALL IT BECAUSE YOU SAY ITS NOT A SAFETY ISSUE? YOU GUYS ARE NUTS, THE MANUFACTURE SHOULD BE MADE TO MAN UP AND FIX THIS PROBLEM INSTEAD OF LEAVING THE CONSUMER STUCK WITH A PROBLEM THAT THEY CREATED AND AN EMPTY WALLET AS WELL, SIMPLY NOT FAIR MANY PEOPLE HAVE BEEN STUCK WITH THIS PROBLEM TO DEAL WITH WITHOUT ANY HELP FROM THE ENGINEERS THAT CAUSED IT, MAN UP AND MAKE EM TAKE RESPONSIBILITY IF NOT THEN WHY DOES THE NHTSA EVEN EXIST AT ALL”
