 This car has been in service for back up camera failure, intake manifold failure, improper reattachment of a gas line by the service staff (scary) and today the engine light went on for some sort of electronic engine failure yet to be determined.  I have only owned the car for 24 months but am ready to sell and buy something I can count on.  In addition, there are many features that are missing that are offered by many luxury competitors such as homelink and the ability to set power seat positions for each driver.  The nav system is awesome and you can link your calendar to send it to the car for appointments.  However, the cool tech does not make up for the poor reliability.  It does not even come close.
