DRIVING THIS CAR IS VERY FUN AND I HAVE ENJOYED THE CAR VERY MUCH BUT JUST LAST WEEK I NOTICED A SMELL LIKE BURNING RUBBER OR OIL, COME TO FIND OUT THE NEXT DAY I WAS DRIPPING OIL ONLY NOT A STEADY DRIP BUT A DRIP ONLY FROM DRIVING, ONCE I STOP AND THE CAR COOLS THE DRIP STOPS. I HAVE RESEARCH AND FOUND THAT THERE COULD BE A PROBLEM WITH SOME BOLTS TO THE OIL FILTER THAT ATTACHES TO THE BLOCK BUT WHEN I CALLED INFINITI THEY DON'T SEE IT NOR WILL THEY LOOK AT THE CAR UNLESS I PAY. THIS ISN'T A SEAL OR GASKET THIS IS A VERY BAD LEAK, MY RESEARC…

ISSUE: PASSENGER SEAT BELT LIGHT CONTINUES TO REMAIN ON AFTER THE PASSENGER IS NO LONGER SITTING ON THE SEAT. ROOT CAUSE FROM DEALER: DEFECTIVE PASSENGER OCCUPANCY SENSOR. ONLY WAY TO TURN OFF THE SEAT BELT LIGHT IS TO EITHER PUT THE PASSENGER SEAT BELT ON OR TURN ON AND OFF THE CAR. I NOTICED WHEN I PURCHASED THE INFINITI 2011 M56 THE SEAT BELT LIGHT WOULD REMAIN ON AFTER A PASSENGER HAS BEEN SITTING ON THE PASSENGER FRONT SEAT AND EXITS THE VEHICLE. THE PASSENGER JUST NEEDS TO SIT ON THE PASSENGER SIDE FOR A FEW MINUTES TO EXHIBIT TH…

4WAS AND STABILITY CONTROL WARNING LIGHTS COME ON WHEN DRIVING OVER ROUGH ASPHALT, OR TURNING RIGHT OR LEFT AND ROAD IS ROUGH. THE REAR OF THE CAR FEELS UNSTABLE AND STEERING WHEEL IS OFF-CENTER. THE LIGHTS ARE ON UNTIL THE CAR IS TURNED OFF. WHEN THE CAR IS TURNED ON AGAIN AND BEFORE THE WARNING SYMBOLS COME BACK ON, THE STEERING WHEEL IS CENTERED AND CAR DRIVES FINE. INFINITI HAS RECOMMENDED REPLACING THE HICAS ACTUATOR. THIS HAS NOT RESOLVED THE PROBLEM FOR INFINITI OWNERS AND ARE THEN RECOMMENDED TO REPLACE THE 4WAS CONTROL BOX. REPLACING T…

WHEN YOU GO TO APPLY THE BRAKE IT OFTEN LOCKS UP AND STOPS IMMEDIATELY. THIS IS AN ISSUE THAT COMES AND GOES. IT ALSO AT THE SAME TIME IT IS STOPPING ABRUPTLY WITHOUT APPLYING THE BRAKE COMPLETELY IT WILL DO THE OPPOSITE AND THE BRAKE WILL DEFLATE ALL THE WAY TO THE FLOOR BEFORE STOPPING. WHILE STOP IT WILL LOSE PRESSURE AND THE BRAKE WILL SLOWLY GO TO THE FLOOR. HAVE TAKEN IT SEVERAL PLACES AND THEY CAN NOT FIX. HAVE HAD ALMOST ALL BRAKE PARTS REPLACED AND OR CHECKED. THIS HAPPENS EVER TIME BRAKES ARE APPLIED FOR A WEEK OR SO THEN GOES A…

I STARTED THE CAR UP AND STARTED TO DRIVE TO WORK ABOUT 3 MILES INTO DRIVING THE CHECK ENGINE LIGHT CAME ON FOLLOWED BY REVS WITH NO POWER OR SPEED GAIN AND THE VEHICLE WAS GIVING ME AROUND 15MPH TO THE POINT WHERE I COULDN'T GAIN MUCH MORE SPEED AND HAD TO PULL OFF THE ROAD. THERE WAS A VOLUNTARY SERVICE CAMPAIGN FOR THE TIMING CHAIN BUT IT HAS SINCE EXPIRED AND NOW I AM STUCK WITH THE REPAIRS.
