 I purchased a 2.5S Coupe (Precision Grey) and had 2 problems already.  After having it for 5 days, the car would only start after pushing the start button 15+ times (which the service technician claims it's a defective battery - we'll see)  and the a/c compressor has to be replaced (was making a rattling noise).  I've had an altima since it debuted in '92 and had no problems with its previous versions.  I'm hoping that the new coupe doesn't prove me that Nissan is now marketing more on design and failing on overall reliablility.
