We bought our Highlander four years ago and have loved it til now. It seems there are a batch of Toyota 6cyl engines with bad valve seals. Toyota was repairing these engines until 2010. They absolve themselves after a vehicle is 8 years old. We bought our Highlander in 2010 with only 87000mi. It now has 133000mi. Now in the last six months the engine consumes large quantities of oil. The symptom of these engines with bad seals is they consume oil when driven at highway speeds. A service mgr at the local Toyota dealer
confirmed this valve seal problem when I described the pattern of oil consumption, a $2700. repair at the dealer if it is still repairable! the six seals cost $6 each!

We bought our 2002 dark green 4 cyl Highlander new, and it now has 353,800 miles on it!
We have replaced the catalytic converters, A/C knob, and just recently, the timing chain. The car still looks great inside and out.
When (if!) it ever dies, I'll buy another one. We have always owned Toyotas because they are so dependable and low-maintenance, but this is the best one ever.
