2011 TOYOTA TACOMA Engine Problems

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

2011 TOYOTA TACOMA EXPERIENCES SPARK KNOCK (DETONATION). SAME SYMTOMS AS IN T-SB-0044-14. ALSO, THE 2011 ENGINE IS THE SAME ENGINE THAT IS IN THE 2012 VEHICLE COVERED BY T-SB-0044-14. SO WHY IS THE 2011 MODEL NOT COVERED BY T-SB-0044-14? I PURCHASED THE VEHICLE THROUGH THE CERTIFIED USED VEHICLE PROGRAM AT THE LOCAL DEALER IN JANUARY 2014.

THE VEHICLE'S ENGINE MAKES A STRONG GURGLING SOUND, LOSES POWER AND RUNS SLUGGISH AT TIMES. TOYOTA CLAIMS THAT THE VEHICLE IS RUNNING THE WAY IT WAS DESIGNED. I HAVE TAKEN THE VEHICLE BACK TO THE DEALERSHIP TO HAVE IT FIXED, BUT THEY CLAIM THAT THE COMPUTER IS UNABLE TO FIND ANY DEFECTS, THEREFORE THEY CLAIM THERE IS NOTHING WRONG WITH THE VEHICLE. I HAVE REQUESTED A TOYOTA ENGINEER TO INSPECT MY VEHICLE BUT IT HAS BEEN TWO YEARS LATER, AND I STILL HAVEN'T HEARD FROM TOYOTA. THEY ALSO CLAIM THAT THE VEHICLE WAS ALREADY INSPECTED BY A SPECIALIST (ENGINEER), BUT IT'S A LIE, I HAVE ZERO DOCUMENTATION STATING SO. PLEASE HELP ME. *TR
