Less than a month after replacing my original windshield (small chip developed into a 15 inch vertical crack from just under the drivers side wiper) - while driving on the 91 Freeway in Corona, CA - a small piece of debris hit the upper passenger side. By the sound of the impact I didn't think much about it - then noticed a dime size star chip! I freaked! Within five days (after sitting in the sun for an afternoon) a crack has appeared - about 18 inches horizontal across to the mid point of the windshield. My insurance does not cover glass breakage - so it looks like another out of pocket trip to the dealer.

I am beginning to think that smart (MB) may be using a poor quality of glass material in the smart windshields. To save weight? Other reasons?

I have owned many MB's and BMW's in the last 30 years - experienced many debris hits to windshields from mild sounding to startling and have replaced only one windshield due to cracking - on a car with over 140 thousand miles! Never on a car with only 8000 miles on the odometer.

Does anyone else think that the quality of the glass in smart windshields is less than it should be? Sorry to say - but if the windshield cracks a third time - it might be time to rethink owning a smart.

An inconsiderate,wanabee Arizona cowboy in a pickup with on/off highway tires, without mudflaps,stoned my windshield... Luckily , I have full glass coverage as the OEM windshield alone is $373....The position and slant of the windshield suggests this will not be the last time...FULL GLASS COVERAGE FOR SMART OWNERS IS SMART....

My windshield was hit by a rock on the left-hand edge in Arizona last summer, and by the time I got back to Chicago, the crack was a quarter of the way across the width of the pane just below driver's eye level. At least the insurance company recognized that this was a special type of installation, and approved it going to the dealer, but, it still cost me a hefty deductible. But, at least my bill was only $750 total, not the amount Max got hit with! The wierdest thing was that -- since they needed to keep the car overnight-- they gave me a Mercedes sedan loaner for the day. It felt like a big, smooth-sailing boat after little smartie on all those bumpy, pot-holed Chicago roads! Anyhow, good luck with yours--hope the last time WAS the last time for this problem.

I caught a rock in the center of my windshield on I-40 about two weeks ago and it was not the sound of the rock that shocked me..........it was the bill. Try $874.00!

I had something hit my window from a semi about 3 weeks ago, upper passenger side......LOUD! Scared me.

Think I saw your original window post so I have kept looking at the roof, the part between the roof and glass but no mark, no crack. Still surprised I did not have damage. Sorry to hear about your second crack...........not sure what to think about the glass because we have opposite situations.

I don't think it is the smart-it is the 91 FWY. I have had several vehicles badly damaged from road debris on the 91 from OC to Riverside. My SUV lost two windshields-one to a truck wheel chock that bounced off from underneath the trailer of an 18 wheeler, and another from a chunk of pavement. The 91 FWY seems to be worst than most in SoCal for flying major debris.

You also have to remember that the glass in the smart is a little more vertical than the windshield of most other cars, and would be more prone to taking a direct hit from something, which would much easier cause a crack than a glancing blow.
