NHTSA Complaint #10825980 — 2012 CHEVROLET SONIC

WHEN I PRESS THE GAS PEDAL THE RPMS SHOOT UP BUT CAR EXCELERATES SLOWLY. IT JERKS HARD WHEN SWITCHING TO ANOTHER GEAR AND TAKES SEVERAL MINUTES TO FINALLY GET TO A SAFE SPEED. SOMETIMES THE CAR STRUGGLES TO GO UPHILL AND HARDLY ABLE TO REVERSE. DEALERSHIP CLEARED MY ENGINE CODES DURING MY LAST OIL CHANGE. CHECK ENGINE LIGHT CAME BACK ON A WEEK LATER, AUTOZONE PULLED 3 CODES (P0700, P0300 AND P0717). CHANGED MY SPARK PLUGS, USED LUCAS OIL/5.25 OZ. FUEL TREATMENT TWICE BUT STILL NO CHANGE. SOMETIMES I CAN SMELL BURNING RUBBER. THIS PROBLEM MAKES IT HARD TO SAFELY MERGE ONTO HIGHWAYS AND GET THROUGH TRAFFIC LIGHTS FAST ENOUGH. NOW AUTOZONE HAS ACCIDENTALLY CLEARED MY CODES SO I CAN'T SEE IF ANY OF THE ABOVE LISTED CODES HAVE BEEN RESOLVED.
