NHTSA Complaint #10937265 — 2011 BUICK REGAL

CHECK ENGINE LIGHT ILLUMINATED AT 82000 MILES. USING THE SCAN TOOL FROM A LOCAL AUTO PARTS STORE, I OBSERVED THAT THE OBD-II CODES WERE P0016 AND P0017. AROUND THE TIME THAT THE CHECK ENGINE LIGHT CAME ON, I NOTICED THAT THE SHIFTING DONE BY THE AUTOMATIC TRANSMISSION SEEMED JERKY, AND THAT THE ENGINE WAS NOISIER THAN USUAL EVEN WHEN IDLING. GENERALLY THE MILES ON THIS CAR ACCUMULATE FROM EQUAL TIME SPENT ON BOTH CITY AND HIGHWAY CONDITIONS. THE ENGINE ROUGH IDLE AND CHOPPY GEAR SHIFTING WERE APPARENT DURING BOTH TYPES OF CONDITIONS. THE CHECK ENGINE LIGHT REMAINED LIT FOR FIVE DAYS BEFORE I TOOK IT TO THE DEALERSHIP FOR DIAGNOSIS. DEALERSHIP DIAGNOSIS SAID "JUMPED TIMING CHAIN FRONT GUIDE CAME APART P0011 P0014 P0016 P0017 SET IN SYSTEM." THE DEALERSHIP REPLACED THE TIMING CHAIN USING A TIME CHAIN KIT, REPLACED THE INTAKE AND EXHAUST ACTUATORS, AND REPLACED THE OIL AND FILTER. THREE DAYS HAVE PASSED SINCE THE REPAIR WAS MADE, AND THE ENGINE SEEMS TO BE OPERATING NORMALLY.
