For what its worth I wanted to put down some observations at my 2K mark with my new Tacoma.
So far...so good, but I've noticed a few things since taking delivery. First, I've noticed sort of a whine when the truck is stationary, but in drive. Usually at an interaction, drive through, etc. Just something I've noticed, not annoying, but as you get used to the truck you tend to notice things.
So far, no issues. In fact I've been very impressed with the mileage. Currently driving about 86% city and 16% highway. Getting nearly 20mpg in town which I think is excellent for a 4L V6.
The truck came with Bridgestone Dueler H/T D840s. These are quiet, ride well, but seem to wear very fast. I'll be curious how many miles I get out of these...and I plan on wearing them out and opting for new wheels as well. Got a few in my "list."
I don't like the "chrome clad wheels" that came with my Sport upgrade package, but that will change.
The truck rides very quiet and smooth. Easily the best riding truck or vehicle I've owned so far. (I've posted a comparison between the 2012 Tacoma and the RTS Honda Ridgeline in previous posts).
I have done a few modifications including new N-Fab side steps, bed mat, etc. Nothing major so far. While I'm not too interested in a lift kit I would like to get a set of bigger tires to fill the space in the wheel wells in the future. The majority of my 'off road' or 'stress' driving will be limited to dirt roads and heavy snow in the winter.
I would like to get some real skid plates for the drive train and differential. Relentless is on my finalist list.
If I do need a lift in the future I'll look to Toytec. They are "local" to me and seem to have a great reputation.
So far there are really no problems with the truck. I'm lucky to have a great local dealer and will take it there for the warranty issues, oil changes, etc. In addition we have a great 4x4 place that will take care of lift kits, new wheels and tires, etc.
As in my comparison post between the 2012 Tacoma and Ridgeline I do wish the Tacoma had the storage space of the Ridge. I do think that's made up in the fact that the Tacoma is a much more capable truck. The V6 of the Tacoma, while less in HP has more torque and seems more responsive.
So far I do love the truck and don't expect any issues in the future. I tend to take great care of my vehicles. The long bed has been a bit of a parking challenge for me, but the rear view camera has been a life saver.
