I never noticed that mine is cracked also, until I read this thread. Thanks for bringing it up and keeping us updated. My service guy didn't seemed surprised when I told thim about this. I guess its all over. So, put me in the club...are there any decals?

GM's communication to the dealers in regard to the cracked roof rails.
This message is being issued due to numerous inquiries on the availability of the revised luggage carrier side rails to correct the cracking condition on the front corners. Unfortunately it will be mid May when both the side rails and revised 'A' pillar moldings will be available to correct not only the cracks, but provide a better fit between the two parts. Any side rails replaced with the current stock could crack again, so if a customer agrees, it is best to postpone the repair. I will provide another message with the revised part numbers just as soon as they are available.

Thanks again, f5fstop!

I swear just the other day mine was fine. Tonight while pumping gas I looked again and sure enough on the drivers side it was cracked. Guess I will put some clear Silicone on it until the fix is available...

Guess I'd look into some thin flexible plastic trim at an auto store as a temporary fix if I discover mine cracked. Sometimes you'll be surprised at what you can find at a Pep Boys.

By the way I guess you guys have door guard edge protective strips on your H3s? I just purchased some at a Pep Boys recently. Since my H3 is black the thin strips look like part of the vehicle.

mine is cracked also

I'm also on the cracked list. Oop's that sounds bad.

I hope they make enough replacments?

Good point. I'm going to send my service manager a case of Bud.
