 Purchased in Jan. 2016.  After a few weeks I noticed a lag/hesitation when I would try to accelerate, followed by erratic transmission shifting.  I thought it was part of the breaking in process.  The problem got worse.  I called Toyota Corp. and they opened a case file.  A few days later they called and said no recall had been issued on the vehicle so they would take no corrective action.  I had the dealer do several software updates in hopes this would remedy the problems.  All efforts were met with negative results.  My Tacoma was driving so badly I was concerned I could potentially become involved in a traffic crash so it set parked.  On April 1, 2017, I traded in my Tacoma for a 2016 4Runner which runs 100% better than the 35 thousand dollar piece of junk truck that Toyota sold me.  Very Disappointing.
