We ought the van as a program with 20,000 miles on it, within the first month the power windows would not work all the time meaning sometimes they work and sometimes they dont. Same thing for the interior lights. In the summer of 2003 the air condition developed a sloe leak that progressed within weeks, we now have no air at all and the part aloe is going to cost $400. In October of 2003 on our way to a high school football game the transmission went out. There was no warning at all, it had not been leaking or acting up in any way it made a thud sound going down the hiway and that was it..no more transmission $4,000 to repair.

There are modules that we keep having trouble with. They lock & unlock doors while driving, lock in ignition key receiver, turn on air bag warning light and disengage them, show "'service engine" light, etc..I am told they control the headlights also. They are a vital part to the car\\'s saftey because they control so many elements of the car. The tranmission has had numerous problem. Wheels spin first and then engine locks in a few seconds later. They tried to repair it twice, then we drove just a few blocks from the dealership and had to bring car back (service records do not show this as an additional service) and had too bring it back again a few days later. Now we are told that they are putting in a new transmission and refuse to consider the car a lemon because a new transmission is being put in. We have lost confidence in the car and consider it unreliable and unsafe. A new transmission only addresses one of the problems. We want out of the vehicle. It is currently in repair now, and we have had a rental car for almost two weeks. Altogether, the car has been in service for about 43 days since we have owned it..just one year!!
