Mass Air Flow Sensor problems of the 2012 Subaru Forester

The contact owns a 2012 Subaru Forester. While traveling approximately 60 mph, the vehicle lost all power without warning. The contact was able to coast the vehicle to the shoulder of the roadway. The vehicle was towed to an independent mechanic where it was diagnosed that the mass air flow sensor and battery failed. There was also too much fuel in the system. The vehicle was repaired. The manufacturer was not made aware of the failure. The VIN was invalid. The failure mileage was 65,235.

Which driving on the interstate at rush hour at 65 mph. . . With absolutely no warning or warning light my car stalled. When this happened the steeling went out along with the breaks and all power. I sat in the fast lane of traffic unable to safely exit my car for almost and hour until help arrived. I took the car to the dealership neil huffman in louisville ky where I purchased the car new 4 years ago. I was told the mass airflow sensor had failed. I was also told that they had no idea why this happened at 65 mph with no warning. I paid the 403. 00 repair and contact Subaru USA due to my concerns. Although I called several times and was on hold each time for up to 10 min and also emailed. . Still not response. This seems to be a major safety concern. I no longer feel safe in the car. . And plan to purchase a new car soon. . But am concerned someone else will be my car and be in danger.
