Startlingly loud pop when driving at 70mph on interstate. Pulled off to check tires in thick morning rush hour traffic and did not notice sunroof had shattered until some miles later when I continued to hear gravel rolling around on top of my car. A large chunk of window had flown off the back, apparently. Fortunately, screen was closed. And, the cars behind me were not effected. I do not recall anything hitting the sunroof nor was I behind any trucks that may have had loose rocks. Cost to repair is $935!!, all out of pocket since my deductible is $1000. This should not have happened! Volvo service tells me this happened to another car recently!!
