What sort of problems are you having with your 09 B?
I'm not saying that the problem is fixed but I do think it's getting better. The maintenance problem isn't as bad as it use to be. People blow it way out of proportion.
The truth is people are starting to have problems with Infiniti, Acura, Lexus (japanese luxury brands) more often now and the German brands are starting to become more reliable. Most of the Japanese luxury manufacturers shifted manufacturing over to USA and quality control has gone down alot. I've heard many complains about Infinitis have problems often from friends who have recently purchased them. I've also read of many problems with the Acura cars having bad quality control. In terms of the motors the japanese cars still have great reliability but the electronics aren't exactly as perfect as people say they are.
