Consumer states that the transmission failed 3 times. The vehicle was taken to a service station and put on the computer, but they couldn't find what was wrong. The intake gasket blew twice allowing water in the engine.
Air conditioner leaks coolant and needs to be repeatedly serviced because air conditioner blows warm air. Air conditioner checked when under warranty 4/1/98 and dealer stated recharged a/c. However, coolant needed to be added 5/28/99, 5/12/00, 4/29/01, 6/9/04 for a total cost of $482. 48. Dye injected and no leak noticed. Leakage occurs over months where dye not detectable.
