Loud engine rattling noise on startup of 3.6L v6 then check engine light came on. Carl Black GM Buick dealer replaced valve actuator solenoid, but engine still making the rattling noise on startup. Danger of timing chain and valve phasers not synchronizing causing valve interference with pistons and engine damage and failure in high speed traffic on Atlanta GA freeways and 2 lane side roads.

MAKES A BAD RATTLING NOISE AT FIRST START UP. PROBABLY THE TIMING CHAIN. *TR

I HAVE A P0420 CODE ON MY 2014 BUICK ENCLAVE FOR ABOUT A YEAR NOW. ALMOST EVERYTHING RELATED TO ENGINE PERFORMANCE WAS REPLACED BECAUSE NO ONE COULD BELIEVE THAT THE CATALYTIC CONVERTER WENT BAD - EVEN AT THE DEALERSHIP - ON A 4 YEAR OLD CAR WHERE THE AFTERMARKET CATALYTIC CONVERTER HAS A 5 YEAR WARRANTY. I SPENT OVER $2,000 SO FAR REPLACING ONE THING AFTER ANOTHER AT THE DEALERSHIP'S ADVICE BECAUSE THEY DID NOT EVEN KNOW THE REASON FOR THE FAULT. NOW I KNOW IT IS THE CATALYTIC CONVERTER BECAUSE THE EXHAUST STARTED SMELLING BAD WHENEVER THE CAR IS RUNNING. GM/BUICK SHOULD INVESTIGATE WHY ITS CATALYTIC CONVERTERS ARE FAILING AND FORK THE BILL ON FIXING IT.
