Exploding sunroof

Honda -- Hello! My sunroof also exploded two days ago. The temperature was 55 degrees and I was out in the middle of nowhere in Idaho, miles from any town or house. No one had passed me or come by in many minutes, I was doing 65, and the sunroof just went up like an explosion. It looked like a crown with all the shards sticking up. My Honda dealer said something hit it -- NO, NOTHING HIT IT. It's a 2012 Honda Accord EX. Honda better start owning up to this defect.

I am curious about this as my 2015 also has a sunroof. Luckily it has not shattered!
My Accord was built in Marysville. Could the plant's quality control be inferior at each building location?
I have noticed small quality defects on my wife's CR-V that was made in Mexico.

This 2012 Accord was built in Marysville also. Now that I can see the sunroof glass, it's apparent that the glass is really thin. I'm wondering about glass fatigue from being in the slipstream. No matter, Honda needs to fix this. I'm so disappointed that I'm thinking about going to a Toyota Camry. That's a good car.

Google produced a link to a class action lawsuit for exploding sunroofs. W/I that link is explanation that designs have reduced thickness (lower weight) may be source of problem.

I also found a Wall Street Journal article:


Nothing definitive, but sounds like a design defect. Too many instances of this happening.

good luck

Default Exploding Sunroof

On Aug. 15, 2017, My 2015 Honda Accord Sunroof glass simply explodes for no reason. This is anywhere from $400 to $700 to replace. Not covered by insurance. This needs to be investigated why this keep happening. 😢😢😢😢

I have a 2011 Honda Accord. Was driving on the highway for about 30 min and "bang" - I could hear the air coming through the closed interior sun roof cover. Pulled over and like above, a huge hole in my sunroof! Was not going under an overpass, was not in back of a large truck or other vehicle. Really strange!! And what a pain as 30 min later it started raining!!!

One thing I'm curious about and what seems to be a common denominator reading this thread is that mostly everyone mentioned they had their shade closed in the car when the "explosion" happened. Wonder if it has something to do with it being closed for some reason? Jeez if it was open at the time you could really get injured with glass fragments.
