“On january 7, 2020 at approximately 8am, I was driving my car which had been warmed up and driving for approximately 15-20 minutes when my windshield spontaneously cracked on the drivers side about 8 inches off center. There was no vehicle in front of me at the time and no visible or audible debris that could have struck the windshield. The crack was about 8 inches long and ran vertically up the windshield. …”

NHTSA complaint #11470429, filed 2022-06“Dear NHTSA Team, I am writing to report a recurring and distressing issue with my Subaru Legacy 2021 which I believe raises significant safety concerns. Since purchasing the vehicle, I have experienced consistent problems with the battery. Despite replacing the battery five times, the vehicle has repeatedly stopped functioning, including a recent incident where it stalled in the middle of the road. This required me to call law enforcement and a towing service, adding considerable mental and financial stress. …”
NHTSA complaint #11632889, filed 2024-12“After shifting my car into reverse, I slowly started removing my foot from the brake pedal. At this time, the car started rapidly accelerating backwards so I put pressure back on the brake pedal to stop the car. When doing so, the ABS light came on my dashboard, I heard a griding sound like the car was still trying to accelerate, and there was a loud constant beep. I was able to shift the car into neutral and then into park to stop the car and then turned the car off. I contacted the dealership about the issue, but have not yet been able to further investigate or bring it into the dealership.”
NHTSA complaint #11588661, filed 2024-05“The trunk does not stay open leading to sudden closing on body and head for anyone trying to use the trunk. Leading to a concussion and multiple injuries.
