An issue has surfaced with my car that it turns off while driving. Obviously this is a serious safety hazard and likely to result in an accident. Now that it has happened, it is continuing and frequently happening. I reached out to Subaru as I saw there was a recall for my car's make and model that is causing the same issue. The issue is listed as the federal safety agency CAMPAIGN ID: 19V297000, described as "The engine turning off unexpectedly can increase the risk of a crash. " and affecting many Subarus, including the 2011 legacy. I believe my car is impacted given the behavior it is exhibiting. When I reached out to Subaru, they dismissed it saying it did not apply to my car and they were not willing to investigate. I believe this poses a grave risk to many people given that it will cause an accident and the severity of the defect.
