No, I don't think so. There are some issues that carry on over model year changes, but there are different views on that. Some people have failed window regulators every year or so, and have replaced them all, some more than once. Some believe that BMW window regulators are very weak. Myself, I have never experienced a failed window regulator in any of my last 5 (recent) BMWs. Maybe it is because I was taught when I was young to never slam the door, particularly when the window was all the way down and not supported by the tracks.

Others think that the oil separator valve is a poor design. I have never had a problem with it. Trouble is, it doesn't deal well with many short trips and the condensate never burning off. So people who have those driving conditions have repeat failures. Others (including me) who make sure that the engine gets hot enough to burn off the condensate have never had an oil separator failure. I did get a buildup of condensate once, so I did an early hot oil change. It's called preventative maintenance. And, that was in a 318 with a four cylinder, it didn't produce much heat.

You can slag any manufacturer if you want to, they are not that different, but they generally address the problems that cost them money and customers. They don't change their design principles because people want to use the vehicles for other than how they were designed.

Maybe you could clarify what you meant by carrying on with the same problems through subsequent models.

PS: fixed your post.
