88 miles -- presumed to be test drive miles at the time of purchase: Very rough idle, unbalanced tires. Six multiple-day visits to the dealer to fix the idle problem. Suspect that the service people operated the truck at idle for extended periods while at the dealer for repair. Claimed low fuel rail pressure was the cause of the rough idle. After five visits, the dealer attempted to dismiss the complaint as "not a new vehicle problem", then repaired it after my threat to escalate the problem to Toyota Regional Support.
1,000 miles: Cruise control cable rubbed underhood insulation and chaffed rubber off the cable. The dealer secured the cable and wrapped with cable with electrical tape!
10,000 miles: turn signal module shorts intermittently. Dealer couldn't resolve. Problem still exists.
103,000: Blown head gasket. Fixed free through "silent recall".
150,000: Clutch replaced.
This has been the most reliable and fun vehicle I have ever owned, and I intend to keep it.
I was at first skeptical of the engine, because it was hailed as the worst ever for Toyota, but it still does what I asks it to do.
Up to and after 250,000 miles, I traveled everywhere at 80 plus mph with no complaint from the engine. It still doesn't use oil, and responds well when I push it, which is a frequent event.
Since it reached 50,000 miles, it has had over 300 pounds of extra equipment on/in it including the stock bed liner, a cab high camper shell, and wood from a piano, which was used to construct a sound isolated stereo system in the bed. Added Monroe "MaxAir" shocks (part number MA792, last mated to the 1983 Toyota truck) to raise and level the truck.
After 180,000 miles, gave up on dealer support due to screw ups and their allowing junior techs to service the truck.
Using the original manuals purchased with the new truck, I have maintained this truck somewhat adequately to this point.
