HAD a 2008 tacoma with the 2.7L 4 cylinder engine and 5 speed manual trany. If you parked it on any amount of hill/grade it would slowly lurch thru the compression strokes of each cylinder and move along down the hill.
So took it to the dealer we bought it at, they did leak down and compression test which matched the compression test I did before taking it to them.
At the dealer, with shop forman in the truck with me, we parked on a slight hill, and sure enough we started to lurch along slow but sure. Then we parked at top of curb, let engine compression hold the truck or prevent it from moving too much off the top of the curb, instead the truck rolled off the curb and started across the parking lot lurching along thru the compression strokes. The only way to avoid hitting the building 20 yards away was to put on the brakes. We tried it with the truck in 1st and reverse gear, same result. We tested a new tacoma off the dealer lot, same engine/trany, had no problems.
End result was the leakage/compression figures were in the lowest 10% of the "acceptable" range". Toyota's response was "within factory specs" and they included the tidbit from the owners manual that says to "always use the parking brake when vehicle is left unattended". Maybe factory specs but I consider the truck a lemon.
I have a old beat up Nissan Sentra with 302,000 miles on the car, and 110,000 miles on a cheapie rebuild (rings, valve job w/o new guides, rod bearings, and timing chain) that does not move when parked on a hill in gear with no park brake.
So I sold the truck, had only 19,000 miles on it, and won't buy another one. MY wife says no more toyotas.
I always buy manual trany, guess I have to park all new cars on slight hills from now to see if the engine compression is any good. Never expected it to come to this.
