NHTSA Complaint #11405710 — 2010 CHEVROLET SILVERADO 1500

ENGINE STARTED TICKING NOISE DURING WINTER 2020 AT ABOUT KM 83000. I CHANGED ENGINE OIL. DURING WINTER NO NOISE AT START UP, ONCE THE OPERATING TEMP REACHES 100 * F. TICKING NOISE STARTS. I TOOK IT TO DEALER, TOLD ME LIFTERS, GAVE ME QUOTE FOR CAMSHAFT & LIFTERS, VERY EXPENSIVE. I HEAR THESE ENGINES ARE KNOWN FOR HYDRAULIC LIFTER PROBLEMS. I JUST PARKED THE TRUCK AS WINTER SNOW & COLD. OUT OF WARRANTY. MY MILEAGE IS LOW. I CONTACTED GMCANADA, THEY REFER ME BACK TO DEALER. THEN ANOTHER DEALER TOLD ME GET AC DELCO ENGINE OIL SUPPLEMENT, GM PRODUCT. I USED THIS, NO IMPROVEMENT, MORE NOISE, GOT WORSE. I PARKED THE TRUCK DURING WINTER. PLEASE LOOK IN TO THIS. ENGINE NOISE AT AROUND KM 83000 ? I CHANGE ENGINE OIL & FILTER REGULARLY. QUAKER STATE SYNTHETIC ENGINE OIL, I LIVE IN CANADA. I HAVE FAMILY IN USA.
