NHTSA Complaint #10502862 — 2012 TOYOTA TACOMA

3-5-2013 TACOMA 2012 TRD 4X4 AUTOMATIC NEW, I NOTICED A VIBRATION ON ACCELERATION IN 1ST GEAR THROUGH 2ND GEAR IN THE FIRST FEW DAYS OF PURCHASE. HOWEVER, BECAUSE OF MY JOB TRAVEL AND JUST BEING LAZY I NEVER DISCUSSED THIS ISSUE UNTIL RECENTLY. THE 1ST TIME I BROUGHT IT TO MY DEALER WAS 31 JAN 2013 13,433 MI. THE DEALER ACKNOWLEDGED THE VIBRATION AND SAID TOYOTA WILL ATTEMPT TO FIX THIS PROBLEM WITH A THREE TIER FIX. 1. THEY ORDERED ENGINE MOUNTS PER TSB. 2. FEB 2013 I BROUGHT THE VEHICLE BACK THEY INSTALLED THE MOUNTS, DID NOT FIX THE PROBLEM. AS PART OF THIS TIER FIX, WHILE IN FOR REPAIR THEY ALSO REPLACED REAR SPRING ASSY. RIGHT & LEFT AND THE FINAL STEP 3. REPLACING STEERING WHEEL DAMPER SHA PER TSB. THE DEALER SAID ALL THIS DID NOT HELP. 28 FEB 2013 14,325 MI, I RETURNED AFTER PUTTING MORE MILES ON THIS TROUBLED VEHICLE. THIS TIME THEY REMOVED THE DRIVE SHAFT AND DROVE THE VEHICLE IN 4WD AND VIBRATION GONE. THEY INSTALLED A DRIVE SHAFT FROM A NEW TACOMA 2013 AND THE VIBRATION RETURNED. THEY SAID THEY CREATED A TAS CASE #. THE ( PRODUCT ENGINEER) ?? SAID THIS VIBRATION IS NORMAL AND CANNOT BE FIXED AT THIS TIME AND IS UNDER REVIEW. I MUST SAY THAT MY DEALERSHIP HAS BEEN VERY ACCOMMODATING KUDOS-KUDOS. I FEEL THAT ANY VIBRATION IN THE DRIVE TRAIN OF ANY VEHICLE CANNOT BE CONSIDERED NORMAL. THIS PROBLEM HAS BEEN WITH TOYOTA FOR A WHILE SO IT SEEMS AND I ASK WHY, WHY,WHY. TOYOTA KNOWS THE ABOVE FIXES DO NOT FIX THE PROBLEM IN ANY WAY. SO WHY ARE THEY STILL DOING IT ??
