Knocking noise coming from engine. Chirp noise coming from camshaft, and coils. Cylinder 7 misfiring, metal found in oil. I took my car to the Dealer because of vibration. Replaced 4 tires, balanced and aligned front end, that did not fix the problem. I took it back to the dealer balanced again and repaired valve stem, that still did not fix the vibration. I took the vehicle to 2 other places, balanced the tires again, replaced rear brakes, rotors, shocks still did not fix the vibration. Took the vehicle back to the dealer again, they road force balanced the tires, that still did not fix the problem. I returned home and the next day started the vehicle and heard a bad noise. Towed it to the Dealer they diagnosed engine failure with no warning.
