Got a 2020 CX-5 purchased new 06/2020 with 1800 miles on it. Drove it several miles to dinner this evening. After dinner wife got in and put foot on brake, did not touch start button. Mazda logo in middle of dash flashed and dials spun forward and backward. Car started fine. There was no indication of low battery voltage. I don't think this is related to the dead battery problem resulting from the sneak circuit from the lift gate anomaly. Any idea what could be wrong?
