I also have a 2002 Highlander and it has had not ONE SINGLE mechanical problem with it, I have a 2WD V-6 with 95K on it and since I maintain it meticulously I get 22MPG in city and on highway up to 27MPG at 70mph…the best auto I have ever owned.It is outfitted with an auto tranny and the tow package (all heavy duty parts for cooling, suspension, amperage, air, etc…a real deal).
