F22 / F23 2 Series (2014 - Current)
The 2 Series coupe is the replacement for the E82/E88 1 series coupe. Production starts in November 2013 on the 228i (N20) and M235i (N55) coupes. Look for them in dealerships in February 2014. The convertible F23 2 series will follow in the fall of 2014.

M235 sunroof spontaneously shattered

The other day I was enjoying a ride on a beautiful cool day (low 60's) with the sunroof up in the tilt position -- cruising along at about 60 mph with no other cars/trucks around me and suddenly heard a loud "BANG" and bits of glass rained down on me and all over the cabin. I'm glad I was alone in the car and thankfully was not hurt. There was no projectile in the car; can't figure out how rock or whatever could be the causal factor as the angle of the tilt was very shallow (maybe a small meteor!) I called the local dealership and immediately drove over. They gave me a loaner and BMW will cover the repair.

A quick google search revealed that, while relatively uncommon, sunroofs do sometimes shatter for reasons that are not clear. Have any of you heard of such a thing with the 2-series? Any ideas as what may have caused this?

I remember some discussion of this back when I had my 3. First I've heard of it on a 2.

M235 sunroof spontaneously shattered

Decades ago the rear windshield in my E30 imploded for no apparent reason. Insurance covered the replacement.

I'm wondering if your moonroof glass is tempered. Tempered glass can withstand a lot of force when the force is relatively perpendicular to the glass. But tempered glass can not withstand any real impact to the edge of the glass. Just curious.

Did you tint your sunroof?

Most tint places out here (Arizona) wont tint the sunroofs for this reason. Lots of back-and-forth out there on the web if it causes issues or not, and it's not just a BMW thing.

No, I did not have it tinted; it comes already tinted from BMW.

Yep, that should be fine then. Apparently that's already "in the glass". The tint films that they put on windows are a no-no for sunroofs. I asked three tint companies in Phoenix if they would do tint on my X3 roof (already lightly tinted from the factory) and all three said they wouldn't as it's too much risk and explained the chance of explosion due to thermal expansion (or something along those lines). Keep in mind we practically live on the sun out here...

Same exact thing happened to me today! Thought I was going nuts. Really hoping this isn't going to be a pain in the ass to fix.

Wow, that's awful. Definitely file a vehicle safety complaint. Glad I ordered mine w/ the Moonroof delete.

December 2017 Consumer Reports has an article on exploding sunroofs.
