On XXX, I was operating my vehicle heading Pocono PA, on I-80 in [XXX]. At approximately mile point 142.4, the vehicle's onboard Forward Collision Avoidance System (FCAS) suddenly and unexpectedly activated without any obstruction, hazard, or vehicle ahead. The abrupt, automated braking and system intervention caused an immediate loss of vehicle control, forcing the car into a 180-degree spin. The violent shift in momentum caused the vehicle to roll over on the highway before coming to a stop. No other vehicles were involved in the initiation of the crash. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The passenger-side mirror on my Ascent has been damaged and removed since March 2025. I paid for the part on April 8, 2025 and was told it would arrive in a few weeks. As of July 1, 2025, the part has been delayed until August. The mirror is critical for visibility and safe operation. My wife drives this car daily with our infant. Subaru has refused to provide a rental, and the car is unsafe. I’ve contacted Subaru Corporate with no resolution, despite my continued persistence in contacting them through visits to their dealership in Plano, TX and several emails.

The heated seats do not heat. They are luke warm and you can barely feel any heat. I took the vehicle to my local Subaru dealer and they determined there was no issue. Was told the seats are not suppose to get hot. So what is the point of heated seats then? There are several online groups for Subaru where owner discuss issues with their vehicles and give advice. There are many customers who are complaining about the same thing. (Seat being luke warm). Then there are other customers who say their seats get super hot on the same model vehicle. I contacted Subaru of America, told them about the issue and the complaints in the online groups about the issue. They only advised me to go to a different dealer and be retested. Obviously in certain vehicles the heated seats are defective because some people say they are super hot and some say they barely get warm. I just can't get anyone at Subaru to admin there is an issue and take corrective action. I am ok with you inspecting the vehicle. no warming lights on indicating a problem. The vehicle was bought new October 2023 and the seats have always been this way. I feel that the seats are defective in some manner and that alone is a safety risk. All that energy that is suppose to be heating the seats and isn't has to be going somewhere and could lead to a fire or electrical shock.
