NHTSA Complaint #11670460 — 2018 CHEVROLET SILVERADO 1500

My 2018 Chevrolet Silverado with a 6.2 engine suffered a Connecting Rod Bearing failure causing the engine to seize/lock up. The engine components are available for inspection. The engine seized/locked up and could have caused a crash. The vehicle is at my mechanics shop right now and will remain there until it is repaired. The vehicle has been inspected by my mechanic but no one else. The engine had developed a "tick" at idle and while driving. My mechanic found a bent pushrod in the engine and then found the engine suffered a camshaft lifter failure. He replaced all the pushrods, camshaft lifters, and the camshaft. It had been repaired and had been driven for a test drive. There were no warnings the engine was going to to fail. The engine just locked up without warning. The engine was removed from the pickup and was then disassembled and found to have had a connecting rod bearing failure on cylinder 7 and cylinder 8.
