New BMW owner - this stuff normal?

I am in the second month of owning a CPO 2010 328i sedan. 42K miles. This is my first BMW after many years of Honda and Toyota ownership. I realize it's a very different type of car, so I am still learning! I love the car, it looks and drives great - fast, sure handling. All systems on the car report OK -- But there are little things I wonder about -
1. The car has been back to the dealer once and will be going back again because the rubber moulding that runs along the bottom of the rear window - seals between the rear window and trunk lid - is separating from the window, leaving a large gap. Dealer attempted to repair, separation is now worse -- common complaint?
2. When decelerating to a stop, the car sometimes abruptly and very noticeably downshifts hard into a lower gear (2nd??). I also feel when pulling away from a stop, there is hesitation and a hard shift (a late downshift into first gear??) when i push the accelerator. I tried faster starts, slower starts - it seems the car pulls away smoother if i make a fast start - is this normal?? I see posts about hard 1 - 2 and 2 - 1 shifting, but it appears to affect earlier model 7 series... all that said, i was given a brand new 2013 3281 as a service loaner and it seemed to shift in a pattern similar to mine when put in "Sport" mode ... so is mine shifting as it should?? All other shifts are very smooth and appropriate, so i want to think the transmission is mechanically sound, might have a programming issue?? The hesitation off the line has me a little concerned...

This is the first time I've read about this particular issue. I'm sure others have experienced it but it doesn't seem common enough to have warranted a mention on this forum.

This seems unusual to me. I haven't read many complaints of hard transmission shifts with the 3-series. I have read quite a number for the E53 X5 series. Enough to give me the impression there's an issue with the design of the transmission. Given this I would have it checked out. BMW will probably state they couldn't repeat the issue or that it is normal behavior. But from what you've describe I believe it is abnormal.

I had this happen. They tried at first to just add more adhesive in there and it came out worse in a week or so. The next time they replaced the trim and it has been fine ever since. Mine was pretty new when this happened.

I believe both issues have been discussed, especially the second extensively. Try a 'Search'.

OP try a search for the Adaptive Auto Transmission Reset Procedure. Here is a link: http://www.bimmerfest.com/forums/sho...d.php?t=261285

THANK YOU - very helpful. Helpful for the reset procedure, I'll try it when I get home next week, and for the redirect to very useful posts. Helps me to see what to look for when searching! Thanks again.

AMAZING! I did the *very simple* procedure last night and the car drives even better!! The hesitation is GONE, shifts are smooth and as expected, including down shifts! I see in the other threads the benefits may be only temporary, so we'll see!

THANK YOU!!!
