NHTSA Complaint #10651541 — 2008 TOYOTA TUNDRA

2008 TOYOTA TUNDRA TRUCK WITH 5.7L ENGINE. VEHICLE HAS A LOUD KNOCKING NOISE THAT SEEMS TO BE A VALVE TRAIN NOISE WHEN TRUCK IS ACCELERATING AFTER SLOWING DOWN, UNDER LOAD OR TOWING A TRAILER. TOOK TRUCK TO THE DEALER MULTIPLE TIMES SO FAR , WITH FEEDBACK RANGING FROM CAN'T HEAR ANYTHING TO THIS IS A NORMAL NOISE OF THE ENGINE. I HAVE READ MANY POSTINGS ONLINE ABOUT THIS ISSUE BUT DEALER DOES NOT RECOGNIZE THE PROBLEM AND INSISTS CONDITION IS NORMAL. THIS SEEMS TO BE A POOR DESIGN OR POOR QUALITY THAT TOYOTA NEEDS TO ADDRESS. I OWN SEVERAL TOYOTAS AND IT SEEMS QUALITY STANDARDS ARE REALLY DROPPING LATELY. PERHAPS IT IS TIME TO MOVE AWAY FROM TOYOTA BRAND. THIS ENGINE SITUATION COULD BE VERY DANGEROUS ISSUE IF A PART INSIDE OF THE ENGINE BREAKS OFF AND CAUSE THE ENGINE TO SHUT DOWN, LEADING TO LOSS OF BRAKING AND STEERING CAPABILITIES. *TR
