Carrier/rack problems of the 2011 Nissan Murano

At approximately 8:30 am on 12/18/17, I was driving on I-70 in denver, CO, going about 60 mph. Weather was a partly cloudy day, 45-50 degrees, road conditions were dry. As I was driving, I suddenly heard a loud pop or explosion, looked in rear view mirror and saw glass flying behind me, coming from my car. I slowed down immediately and exited the highly, pulling into a gas station to see what had happened. I exited the car and looked from the outside and the sunroof had completed shattered, leaving a huge hole. Fortunately, the inside shade was closed so all the glass blew out of the car and not into the interior. There were no other vehicles involved, nor was the police contacted. I had the sunroof replaced at safelite autoglass for a cost of $885. 03. After the repair, it was noted that the interior shade would not open completely and seemed to be off track and the manager at safelite suggested I take it to the dealer. Took the vehicle to anissan dealer, who charged $99. 95 just to look at and diagnose the problem with the shade. Diagnosis was the shattered glass had damaged the track and shade and both would need to be replaced at an estimated cost of $1600. 00 (more detailed diagnosis could be provided after removing the headliner). We declined this repair at this time. So far we have paid out-of-pocket for the repairs at a total of approximately $985. If we choose to repair the shade and track, total cost estimates would be $2,584.

I have noticed on numerous occasions this summer, a crackling sound in lower portion of the front windshield. I actually remember hearing it last summer but it is now more audible. The warm weather must be a factor. I have also experienced problems with my keyless fob, it does not always work and my ignition an rear lift gate sometimes will operate even when the fob is within 3 feet. This has occurred several times over the past 2 months. I took it to Nissan and they could not find the problem. I purchased the car brand new in Aug. 2011. No accidents.

While traveling approx 65 mph on the highway with no trucks or overpasses around my sunroof glass literally exploded! I thought I had a tire blowout until I heard wind coming from the roof and saw bright light from the sunshade crackes. When I opened the visor a crack you could see the glass had exploded upward. I had a large chunk of glass missing from the sunroof. I saw another complaint on nthsa for the same situation and I an very concerned about the safety of the glass. Thank you for you consideration! sara.
