Attention to details and the simplification of the control system.

A good example is a friend of mine whom I convinced to buy an X5 over the Acura MDX is having problem with AC control.
This is a vehicle that is barely two weeks old, and the AC control stopped functioning yesterday. I feel really bad because I know he would have gone with the MDX if not for the role I played, and that is embarrassing. I spent almost 30 minutes trying to get it to work without success.
He had to drive his old civic to work today because it is extremely hot here.

So, attention to details, and simplifying those controls will reduce some of the issues.
