“I bought this car January 2021. In June 2021, the smallest pebble cracked my windshield while I was driving on the freeway. Yesterday, 3/28/22, I was driving home from work like usual and my sunroof spontaneously exploded and completely shattered. Yep, you read that right. Don’t believe me? Search up: Subaru exploded sunroof on Google. Thank god I had the sunroof shade closed or else the glass would’ve fallen all over me. …”

“On two incidents randomly and without warning the car failed to accelerate while driving in traffic on an open road and I had to coast to safety and put in park, then drive, then travel less than five miles home. Both times I immediately scheduled service with suburu with appointments about a week out. The car drove without incident while awaiting service. Service failed to replicate the problem, diagnose or remedy it after having the car a week and I was told“vehicle is operating properly at that time”. …”

“Sunroof exploded outward, the majority of the glass was blown away. The sunshade was open. The temperature was 56 degrees. I was traveling north on I 15 in Davis Couty, Utah. I was not injured, there were no other occupants. I drove to Subaru dealer, they said they have seen this before, only one case. It was inspected by service dealer and deemed safe to drive with sunshade closed. There were no warnings, the sunroof is used infrequently. There were no other objects on the roof.”

“Problem 1)Had my '21 Sport for 7 days. Started stalling few times when shifting from P to R while on a slight incline (dash lights up like in Acc mode) after driving it for about 30 min before and then turning it off to go inside of the store, etc. after about 2-5 minutes of idling, the car engine stopped like I was in auto stop, but didn’t kick back on when I shift gears to reverse or when I applied gas. But then I hit the on/off button and engine turns over just fine. …”
