While into a road trip from Florida to Tennessee on I-75 the sunroof spontaneously exploded. The interior sunshade was closed. Otherwise the glass shards would have entered the interior. The glass most likely would have caused cut injuries to the driver (my wife) and I. Also, it may well have caused her to lose control of the vehicle resulting in a very serious accident while driving at 75 mph. My insurance company classified it as vehicle mechanical failure and not covered by my insurance. They indicated this has happen to other vehicles including Lexus. The replacement cost for glass and labor was $1,087.75
