    My 2012 increasingly frequently makes a single beep when driving, typically when turning and occasionally when braking, but I can see no other pattern. No warning lights or messages. Just a single beep. I did try searching the forums, but most "beep" posts relate to multiple beeps, including when in reverse. This is just a single, random (but increasingly frequent) beer. TIA

    I can't help to point out that you have a problem with an "increasingly frequent beer". Perhaps if you keep drinking that beer, you won't be bothered by the beep any longer :)

    Seriously, I am as stumped as you are. I see some posts that mention a beep if the hatch isn't closed properly. That could cause an intermittent. beep if the hatch isn't just right.. My 2013 has issues with the hatch not closing correctly, when my Uber passengers don't close it hard enough. I don't recall any beeps, just a light on the dash.

    Just a guess... A loose or failing door-open plunger switch might open (or close) when the body flexes under load (turning, stopping, accelerating).

    My guess: A wheel speed sensor going bad or developing a loose connection.......triggering an ABS "alarm"......but the associated light doesn't stay on long enough to see.

    I wonder if reading the fault codes will show something stored ?
