I bought this truck in May 2011, hoping it would be a reliable and economical vehicle for me to keep for a long time, eventually becoming my #2 vehicle. Ever since I got it, I haven't been happy with the way the engine idles. It sometimes revs fast, and sometimes wavers up and down. I also dislike the way the transmission shifts. It can sometimes be harsh and/or wait too long to shift. As of now, 3 of my automatic door lock mechanisms have quit working. The A/C blower is noisy, and will occasionally stop working. (If you kick it, it will work again.) I hate the way the brakes make a "clunk" sound the first time you hit them after going in reverse. Other than that, I've enjoyed it.
I bought my Tacoma used in 2011 with about 25,000 miles on it. I drove it for 3 years and 55,000 miles. I never had any kind of trouble with the engine or drive train, as far as reliability. It never broke down. My complaint was the truck always revved a little high while at idle. Also, the shifting was always weird. At low speed it would stay in low gear too long and rev high before shifting. Under load, the engine would knock. 3 of the 4 automatic door locks eventually quit working. The compass/thermo stopped working. The A/C fan would intermittantly stop working. Car was totaled in an accident in 2014, and I replaced it with a full-sized truck for towing.
I bought this truck second-hand to tow a 23' trailer, weighing 5500 pounds loaded. The truck is underpowered for what I'm asking it to do, but gets the job done. Just don't expect to win any drag races. The Sport package handles extremely well for a 4wd live rear axle truck, and is stable towing even with P rated tires. *Update* - upgraded to LT tires. Towing more stable and the effect of the stiffer, heavier tires on handling is barely noticeable. My only real beef is with the 6 speed manual gearbox. It is the slowest, clumsiest tranny I've ever encountered. Forget quickly flicking through the gears - each shift is a two-stage affair with a forced pause at neutral. And it's not just my truck - I drove several examples, and they are all the same. It's a pity, because it is fun to drive otherwise.
Yes I do expect a million miles out of this truck. I bought it just before I retired from the Army. I used it in the field transporting troops and gear, daily driving around town, and hauling a lot of gear across the country. I change my own oil every 5K miles(Toyota filter & Mobil 1). I've added a K&N air filter and a tri-fold toneau cover. Took a trip up to New Mexico and checked the mileage. I got 24.8 mpg. This included highway & city driving as well as a lot of hills. The truck is very comfortable for cross country trips. In addition to changing my own oil, I change my own spark plugs. Maintenance on this truck is easy due in part to accessibility. It also has tons of great storage!
I purchased my 2008 Tacoma 4x4 intending to keep it a long time as they are supposedly known for reliability. Mechanically, the truck was fine and had no issues. I liked the truck and enjoyed driving it. Fuel mileage was OK with an average of 17 to 18 mixed city and highway driving. On the highway, it would get 20mpg if you stay under 70mph. I recently got rid of the truck as the frame was rusting excessively. I have never driven it on a salted road and I did not park it anywhere near the coast. Toyota's rep was extremely condescending and absolutely refused to do anything. No treatment, no coating, NOTHING! Check toyota frame rust issues and realize the problem still exists in '08.
