“Bought the vehicle and basically parked the car in my garage a/o 23 nov 2020. I travel for work most of the time. Between 3 - 7 dec, the car was used by my ex-husband for two trips to the airport to pick me up/drop off from/for a business trip and for me to drop off the title of my old car. …”
NHTSA complaint #11384667, filed 2020-12, 598 miles“This is an issue we experienced with an exploding sunroof of our new Subaru Outback. We purchased the vehicle on december 22, 2020. Within days of the purchase, on december 27, 2020, the sunroof spontaneously exploded while driving the vehicle. Both the sunroof and interior sunroof covering were closed at the time. The fractured glass was broken outward which leads us to believe this is a vehicle manufacturing defect. We have contacted the dealership where we purchased the vehicle and they referred us to Subaru corporate headquarters.”
