 This is my first Taco.  I had fairly high expectations given what I had read.  I tested both the four and six engines, decided on the six because 1 mpg was worth it to get power.  After having owned it for six months (4,500 miles) I would probably not buy it again.  The first issue was a rattle in the door.  Five trips to the dealer eventually fixed it (along with replacing a door panel and some additional foam going in the A pillar).  A couple of more rattles have made themselves known, but not yet annoying, or I am just dreading the trips to fix them, not sure.  The second issue is the engine/transmission.  I have three issues.  1. the MPG is OK in the city and lousy on the freeway.  My most recent trip was about 800 miles, pulled 22 mpg.  Not loaded or towing and stayed pretty much within speed limits and I have a tonneau cover on the bed.  This brings me to problem 2., the transmission.  I have had the TSB performed to deal with hesitation between park and drive (works), the transmission was also down about 20 ounces of fluid.  The transmission still downshifts very poorly, with a very untotyota like "clunk" when coming to stop and going from third to second or second to first.  The transmission can best be described as nervous and unsettled as it hunts to find gears going up and down small grades, hills, etc.  In the previously mentioned trip, it was continually downshifting one to two gears going up hills and grades, with the tach going from just under two thousand rpm to over 3,000.  This brings me to 3., the engine.  It is very smooth, but mileage is just awful.  The engine feels very under powered going up hills and grades unless it drops all the way down to third or fourth gear.  Some one likened it to shifting up in an manual gear too soon, it "lugs" and that is a great way to describe it.  Even on a flat road, you are going to have to mash it to keep with traffic.  I am going to take it back to the dealer regarding the poor mpg, maybe a different one, and see if they can correct it.  But again, would probably not but it again, and would certainly not recommend to anyone.  What a complete disappointment.I traded the Tacoma in.  The unhappy power train was just too much in a daily driver.  It was very useful, and I miss that every day, but that old saying about never buying a vehicle in it's first year (and 2016 was the first year for the V 6 power train in the Taco), stay away from it.  When Toyota works the bugs out, I will look at it again, if I can afford it.
