Erratic tapping noise at idle. Increasingly become more noticeable regardless of operating temperature. Suspected failing valve lash adjuster. Took to selling dealer. Engine teardown revealed debris in engine. Lash adjuster/s loose and pounding into socket on head. Multiple parts preplaced including short block with pistons & crankshaft, heads, cams, valves, lash adjusters, cam phasers and solenoids for VVT, oil pump, Vacuum Pump, etc... -

Over $20K worth of repair work under warranty. Demanded buyback with NCDS claim but Toyota stepped up and completed in deadline - sold to another non Toyota dealer same day as pickup disclosing all work done - not my comfort level to keep a $35K vehicle purchased new that had to be bolted back together like this in such low mileage - why Toyota did not just replace the whole engine assembly is beyond me but I'm sure it was cost and timeline of getting parts I'd assume.
