Recently my 2011 Ford F-150 rear window popped and shattered after turning on my rear window defroster. There was fog on my windows, maybe 40 degrees out, I was parked and within 2 minutes the passenger side window panel popped and shattered.Ford tells me it's not their problem, I have to pay to replace entire rear window, and rear seats have to be removed to install. Not a happy customer!!!

And what ?

Call your insurance company and file a claim.

We have seen DOZENS of them...FORD should be aware by now....

Are you a LEAKPRO because you cause leaks or stop leaks or use the bathroom a lot?

Tempered glass, whether commercial/residential glazed windows, shower doors or automotive glass part can spontaneously burst. Various reasons that are hard to confirm after the fact. Replace said part and move on.

Rick is right about tempered being tempermental as it by nature is put under stress when created, it's in a constant state of compression. I am curious though. These panes are independent from one another, however they are energized by the same power source that heats the elements on the glass. I have seen heater grids in the past go short to ground be the root cause of tempered detonation. Even if you cover the cost of replacement, I would still insist that Ford run a diagnostic on your electrical system to see if a short exists.

Is this a regional issue? We do tons of pickup trucks and have never come across this. Other than that I'd second the diagnostic suggestion. It would truly suck for it to happen twice due to an electrical issue.
