Consumer Description

AT ABOUT 75,000 MILES MY 2016 SONATA LIMITED 2.4L STARTED NEEDING OIL ADDED BETWEEN REGULAR OIL CHANGES (ALL MILEAGE AND MAINTENANCE BY ONE DRIVER). THE VEHICLE IS NOW 85,000 MILES AND I AM ADDING 2 QTS. THERE ARE NO LEAKS FROM THE ENGINE SO IT MUST BE BURNING THROUGH THE EXHAUST, WHICH CAN'T BE GOOD FOR THE EMISSIONS SYSTEM AND ANY FUTURE SMOG CHECK - OR THE ENVIRONMENT. THE DASHBOARD WARNING LIGHTS DO NOT COME ON WHEN THE OIL IS LOW. THIS COULD RESULT IN CATASTROPHIC ENGINE FAILURE. THE VEHICLE ALSO EXPERIENCES ENGINE KNOCKING AND HESITATING WHEN ACCELERATING FROM 30MPH. THIS HAS BEEN A SAFETY ISSUE WHEN MERGING ONTO THE HIGHWAY, WHICH IS ALMOST ALL OF MY DRIVING.
