Given the new platform, it'll be useful for people to post stuff like this, so we can watch for trends.
On my Execuline (Canadian version of SEL Premium), no cracks, but the driver's side blind spot indicator keeps coming on for no reason, but only when it's wet (raining, or recently rained). Luckily it also still comes on when it's supposed to. Not sure if it's a mal-adjusted sensor (if they even can be adjusted), a short somewhere, or might be as simple as a software error.
So far, nothing else of note. For the moment we're gathering data on this glitch, and we'll bring it in at some point. I want to see if I can reproduce the problem with a garden hose spray or something first.
