If your Subaru's engine cranks up and switches off by itself, do not be afraid as your car isn't possessed by supernatural forces. What happens is that if the remote starter key fob is dropped, a software glitch could occur and it may randomly transmit an engine start request without pressing the button.

The engine will run for up to 15 minutes, but could continue to start and stop until the petrol tank is emptied or the fob battery goes flat. The danger is that if the vehicle is parked in an enclosed area, there is a risk of carbon monoxide build-up which may cause asphyxiation.

The problem affects the 2010-2013MY Legacy and Outback as well as the 2012-2013MY Impreza fitted with automatic or CVT transmissions. According to Subaru, around 47,000 cars are affected by the recall in the United States. Subaru dealers will replace the fobs free of charge.

This issue with Subaru key fobs also serves as a reminder to all of us to take care of our key fob. Personally, I've left mine in my pocket before and it went into the washing pail. Fortunately, it is still functional.
