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 ??.
