06 V8 SE- Engine knock @ 43K miles. Dealer called it "piston slap" and is very lound in the winter time. Had Toyota engineer looked at it back then he said it safety to drive but Toyota will replace the engine if the noise becomes constant or if the engine blown due to related issues even after 60k warranty expired, all being documented and written statement at local dealer. Just have to deal with the knock, which only last about minute or two.Anybody have any problems with their 4runners? Anything from Electrical to the Engine. Post the year and mileage. Curious to see whats common.
almost 222k now
Dealer called it "piston slap" two.
OK, I am impressed. 220,000 miles. I was a little concerned about the V6 engine and it's reliability, but that is good to know one V6 made it that far.
Mines at 236,000, its an '03 v6, still rides smooth and drives strong, minus a few tierod ends and a control arm that is. T4R = unstopable? fingers crossed anyways.
