I have a brand new 2003 Mitsubishi Montero Sport with a 3. 0 engine. The cam shaft came apart and the Mitsubishi rep refuse to authorize the repair. This vehicle is still under the new car warranty. Nothing was done to repair my vehicle. The SUV needs a new engine. What happen to customer service?.
