NHTSA Complaint #10794786 — 2011 NISSAN QUEST

3.5 L MOTOR HAS UNUSUALLY HIGH OIL CONSUMPTION AND PINGING WAS NOTICED YEARS AGO WHEN VEHICLE WAS BROUGHT IN FOR RECALL AND NOTIFIED SERVICE ADVISERS BUT THEY PAID NO ATTENTION TO IT SAYING NOTHING COULD BE FOUND. THERE IS NO OIL PRESSURE GAUGE TO ALERT DRIVER OF LOW OIL PRESSURE. CHECK ENGINE ICON COMES ON BUT DOESN'T ALERT DRIVER AS TO WHAT THE PROBLEM IS. VEHICLE IN QUESTION WAS TAKEN IN FOR OIL CHANGE MONTHS AGO AND WAS TOLD THERE WAS VERY LITTLE OIL BUT THERE WERE NO WARNINGS DETECTED AND THERE ARE NO KNOWN OIL LEAKS. CHECKED OIL LEVEL WHEN THE CHECK ENGINE ICON CAME ON AGAIN AND TOPPED OFF OIL LEVEL TO SAFE AMOUNT AND THE NEXT DAY IT CAME BACK ON AGAIN WITH NO WARNING SIGNS OF A VERY UNSAFE OIL LEVEL(OIL WAS NOT PRESENT ON THE DIPSTICK). MILEAGE FOR VEHICLE IS AROUND 70K+. ONCE AGAIN PINGING WAS NOTICED AND NOTHING WAS DONE ABOUT IT FROM THE DEALERSHIP SAYING THAT THEY COULD NOT DETECT ANY PINGING AND NO KNOWN OIL LEAKS WERE FOUND WITH NO VISUAL EVIDENCE DETECTED.
