“Check engine light came on, took to my machanic.dignostic read out indicated something to do with air pollution device( he did not know which one) until he looked at the car. Now I have a wrench light on and the car does not want to stay running, smells rich running and will hardly go down the road. Not too long ago I had problems with the door lock system also, was relocking doors after I locked them. I have complained since day one that there was something not right with the electrical system on this car. I think whatever is wrong with the engine now is all tied into everything.”

However, the consumer was informed that windshield wipers, transmission fluid and new tires were needed. Shortly after the visit to the dealer, the consumer purchased new tires from another dealership. …”
