Rear passenger door behind the driver side of vehicle will not open up it causes safety issues for passengers and not being able to exit or enter through that door. It is not an electronic problem as the other three doors operate correctly. This vehicle has only 52,000 miles.
Glass in front of the moon roof exploded outward. Corners where collapsed inward. Traveling aprox. 50 mph. Clear sunny day. No traffic in front or behind. My first thought was flat tire. Glass was standing straight up with a 2 in gap in the center. The next one may completely leave the vehicle and cause an accident. Not looking for reimbursement. Paid by insurance. I think there was some sort of pressure on the glass to cause the damage making it a product defect.
WHILE DRIVING APPROXIMATELY 55/MPH ON THE 210 FWY. WEST; I HEARD A JARRING POP/EXPLOSION. I THEN SAW BLACK FLYING DEBRIS ON THE PASSENGER SIDE OF THE CAR. WHEN I ARRIVED AT MY DESTINATION, I SAW THAT THE GLASS FROM THE REAT PART OF THE PANORAMIC ROOF HAD SHATTERED AND SETTLED INTO THE SHADE COVERING. I DID'T SEE ANY DEBRIS ON THE ROAD, OR ANYTHING TOSSED FROM ANOTHER CAR. THE CAUSE OF THE INCIDENT IS UNKNOWN. I DID ADVISE MY INSURANCE CARRIER OF THE INCIEDENT, BUT HAVE NOT YET FILED A CLAIM, AS I AM WAITING TO SEE IF THE DAMAGE IS COVERED UNDER THE CAR'S WARRANTY.
ON 6/29/18, APPROXIMATELY 9:30AM, TEMP 85. GOING SOUTH ON I-25, AT 70MPH, I EXPERIENCED A RAPID EXPLOSION OF MY SUNROOF. IT EXPLODED OUTWARD, ALTHOUGH SOME GLASS CAME INTO THE CABIN. NO ONE WAS INJURED.
