The motor in my 2013 Subaru XV cuts out when I stop. Sometimes it's only for a few seconds, other times it will stay off until I take my foot off the brake. Is this a fault with the car?
The XV is equipped with an idle-stop function, which is designed to reduce fuel consumption. The engine cuts out when you come to a stop, and starts again when you accelerate off again. It's hard to say for sure from your description, but it would appear that the system is working correctly. If you're not sure it is, take the car back to your Subaru dealer and have it checked.
