I bought a 2009 pre-owned 4Runner. Shortly after owning it for a few days I noticed the transmission lag at 15mph especially as your turning. It revs high and then goes into gear. Seems like a lot of people have this issue. It's getting really annoying and especially after you spent so much money on a vehicle this should not be a issue. Thought Toyota was a reputable company with good reliability on their vehicles. This should not be a issue. Toyota should have a fix for this if it's CPU related. Not sure if I would buy a Toyota again.
