This is the first problem I have had with my E since delivery (Feb '03). I recently had the windshield replaced due to a golf ball sized rock coming off a gravel truck. The glass company did a good job I thought, even removing and replacing my State Park sticker on the new windshield. But about a week later when washing it I found one side of the trim piece on the side of the windshield was loose. I removed it and reattached it securely after several tries. Later when I was going on a trip after about an hour of highway driving, the first since the windshield replacement, it flew off. I was able to retrieve it luckily. After another hour the other side flew off also, it had not been loose as far as I could tell, as I had checked it when I put the fist piece back on. The clips do not appear to be damaged but who knows? Any thoughts on this? is there a good technique for puting these trim pieces back on for good? The glass company doesn't seem to know it. Should I take it to the dealer? Thanks for your input.
