On Oct. 6, 2020, while driving North on I-95 in Virginia, nearing Exit 133, our sun roof suddenly and spontaneously exploded outward. We were traveling at about 50-60 MPH and slowing to leave the highway at Exit 133. Our car is a 2020 Mazda CX-5, purchased in July 2020. We have less than 4,000 miles on the car. There is NO evidence that our car was struck by any object that might have caused the sun roof to explode outward. There are no other scratches or dents on our virtually brand new car. Because the sun shade was closed, no shattered glass entered our vehicle. We were fortunate to have not lost control of our vehicle and crashed. The spontaneous sun roof explosion was very loud and it shook the car causing a momentary loss of control. This is probably a Mazda defect.
