Engine Misfire Light
 I have owned this vehicle since August of 2009 and during the first 2000 miles the engine misfire light went on and the manual instructed to immediately go to a service center before damage to the catalytic converter occurs.  I was told that it was not a problem and that the light just needed to be reset.  Then at 4200 miles it went on again and the engine reduced the power so that the car would barely start.  It is now back in the shop for repairs.  When this car performs it is perfect.  However, I am sincerely disappointed with the reliability of this car. Let's face it, being able  to rely on a car to take you where you need to go is the only really necessary feature.
