Absolutely Nothing!
This is by far the most reliable vehicle I have ever owned. Knowing it had 132,000 miles already, I knew it had plenty of life still left in it, and I managed to get it for a steal-of-a-deal. I am very happy with my purchase and would recommend this vehicle to anyone looking for a nice looking, capable, reliable SUV. I've even managed to get 22 miles per gallon out of this SUV.
I totally agree! I bought my Runner w/129K on it and I now have 135 w/no problems at all. Also, I too have gotten up to 22mpg.
Most recently, I have hit 147k and its still running great... not a single thing has gone wrong yet! Squeezed in another couple miles per gallon as well...24 mpg. It must finally be broken in! HaHa.
Just hit 170k, still no problems or loss of power. Would still buy another!
