We own a 2020 Subaru Ascent we purchased brand new. A few weeks ago we noticed a faint gasoline smell while at a red light. I thought it was a one time occurrence but it has been happening now every time the vehicle is at idle or stopped.

While driving on the freeway, your check engine light came on and all safety features (lane departure warning and back-over prevention) shut down without warning. You were able to reach a Subaru dealer, where they discovered a recall on the engine. However, when you contacted the manufacturer about the recall, they stated it only applied to the previous owner and refused to help you with the repair. The dealer never disclosed this pending recall when you purchased the vehicle.
