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. These unexpected breakdowns are not only inconvenient but also pose serious safety risks to myself and others on the road. I am concerned that this issue may not be isolated and could affect other Subaru owners as well. I kindly request your assistance in investigating this matter to ensure that appropriate actions are taken to address this potential defect. Please let me know if you need additional information, such as detailed records of the incidents, repair history, or communication with Subaru regarding the issue. Thank you for your attention to this matter. I appreciate your efforts in ensuring road safety and protecting vehicle owners. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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. FURTHER INSPECTION SHOWED THAT THE CRACK APPEARS TO HAVE STARTED BELOW THE WINDSHIELD WIPER WHERE THE GLASS MEETS THE PLASTIC, A LOCATION WHICH WOULD MAKE IT NEARLY IMPOSSIBLE FOR ANY DEBRIS TO MAKE CONTACT WITH THE WINDSHIELD. THE CRACK HAS NOW SPREAD TO ABOUT 14 INCHES LONG AND NOW RUNNING DIAGONALLY TOWARDS THE PASSENGER SIDE. WEATHER WAS ABOUT 30 AND SUNNY.
