2025 Subaru Legacy Reliability Report

Less than 500 miles cabin fills with engine fumes - smells like exhaust/crank case vapors - especially at idle and with outdoor air damper open on HVAC. If you open hood the engine bay smells like gas fumes. Upon inspection looks like passenger side exhaust manifold is leaking with splatter marks on exhaust manifold - fire and health hazard. Subaru corporate in past has been poor to deal with and makes statements like our dealers are independent and we have no control over our dealers when trying to get them to take action. Now I'll have to battle this out and likely with BBB claim. I have Asthma and cannot drive this vehicle with this smell.

I purchased my 2025 Legacy from Brunswick Subaru (Brunswick,OH) on 9/22/25. A few days later, while riding in the passenger seat, the airbag light/icon stayed off. I am a petite female, weighing 100 pounds. I immediately called Brunswick Subaru's service department. The service manager drove me around, and he saw that what I was reporting was true. He said he would order sensors to fix the problem. I was told that the airbags should deploy at 35 pounds from my salesperson and 80 pounds from the service director. The sensors arrived in December, and I made an appointment on 12/30/25 to have them installed. I waited two hours only to learn that they could not be installed since this was a safety issue and Subaru is all about safety. I had to leave my car, and I was provided with a loaner, which was also a 2025 Legacy. The passenger seat's airbag light/icon stayed off when I sat in the passenger seat of the loaner too. I reported this to Mark Harris, a Subaru Advocacy Rep. He told me to sit in the back seat from now on. He also said to put my purse on my lap to add weight, which is highly discouraged in the Legacy's manual. As of today, 1/19/25, my Legacy is still in the service garage at Brunswick, and no one is giving me any answers-not the service manager, John Cross, nor the Subaru Advocate, Mark Harris. I have emailed and called every day since 12/31/25. Because this behavior occurred in two separate 2025 Legacies, it appears to be a system design defect rather than an isolated incident. The owner's manual states that the airbag may not activate for a "small adult", but this term is NOT defined by weight or any objective criteria. As a consumer, I had no way of knowing that an adult my size would not be protected by the front passenger airbag. This lack of disclosure prevented an informed purchase decision. I believe this presents a safety risk because adult occupants may be riding without frontal airbag protection. I request NHTSA review my concerns

The Legacy (my third one) was about a month old and had about 30 miles on the odometer. I had no warning of any problem with the car. On or about 5:45 PM on Oct 22, 2025 I was driving my Subaru Legacy when the engine stalled. I was in the HOV lane of an interstate highway. Multiple times the starter failed to restart the engine. Traffic was blocked in my lane and diverting around me. It was dusk with a misty rain. My wife and I were felt we were at high risk of being rearended at any moment. After about 5-10 minutes, during which we called 911, the engine restarted. Seeing no help from the police available, I judged it was best. to get off the highspeed road. I was able to get off the highway and make it home, about 5 miles away. I have not tried to drive the car ever since this terrifying episode.
