At least 5 different mechanics, including a Toyota dealer, cannot figure out why there is a smell of raw gas in the car when it idles.
Over $7000 worth of repairs made in the past two years (transmission, front end, various engine issues).
This is my wife's car and she has driven it since new. I have also driven my 2003 Trailblazer since new, and it has been trouble free over the same mileage.
Did she get regular oil changes and service the engine with preventative maintenance? Because it sounds like you didn't have any problems until around 160k miles... and without proper maintenance any car will give you problems after that many miles, regardless of the make and model.
