As reliable as they come. Normal maintenance is of course needed but other than replacing the battery, tires, and 10,000 mile oil changes this truck has been incredibly reliable. We regularly towed a 4,500lb. trailer up steep Colorado mountain roads with no problem. Hauled a lot of detritus from a home remodel and put 80,000 miles on in 3 1/2 years without a hitch.
With other automotive companies cutting cost in areas they feel wouldn't be felt or seen by the owner, Toyota continues to make a affordable vehicle that last as long as you want it to. I own a Tacoma and a Tundra and wouldn't think twice about any other automaker.
