I was wondering if anyone has an experience with the back side passenger window shattering without a cause? I've spoken to 2 other people who own different years and their windows have just shattered with no cause. My back side passenger window did this in a parking lot. Can anyone advise?

EXACTLY the same shattering happened on our 2005 Yukon XL Denali in our garage (garage door was open at the time); I went by and noticed shards of the darkened glass everywhere. Looked this up and such is not uncommon on all types of vehicles (I remember my tennis partner having rear window glass shattering on a few-month old Honda back in the 1980s.

We were fortunate, had glass coverage on the Yukon's policy as included in its comprehensive, so the glass was replaced at no charge by a local company, have no idea the out of pocket cost would be though. If no insurance, call around and request the CASH price, significantly lower than what the charge auto insurers. In my locale, common for windshield replacement companies to hand $100 cash to owner when insurance covers the repair, have had that done 3 times total.

I'll second Cusser. Any window can break for no reason. Thermal expansion, hidden defect from when it was made, mounting issues, lots of possibilities.

Had this happen with the rear hatch window and front passenger window 2 weeks apart on an 02 Trailblazer, rural area with 100 percent certainty that it wasnt vandalism. Never had it happen with another vehicle

While driving with no traffic so no possibility of anything hitting it the rear passenger window just exploded. I felt a weird pressure increase inside the truck then boom I thought I had been Tboned by a ghost truck. I have less that 9k miles and there was no damage to window so not sure why this happens but it is real!

I have Post #2 in this thread and am adding a thought, as I recently broke the rear window of my 1988 Mazda truck. I was using my lawn tractor to cut weeds on my 2-acre property and noticed the shattered window (window film kept it from making big mess though). A quarter-inch stone had been thrown out from my mower, somehow bounced upward and broke it, see stone on my cross-bed toolbox in photo.

So I think a small stone thrown up by a vehicle could do similar while driving.
