I bought my 2015 B-class end of November (supposedly just post the no-sale-until-software-updated recall). Fast forward to last week (and 3000 miles), the EV stalls while by wife drives on the expressway. She was able to pull over to the shoulder, but it did shake her up. The car started back up after a few minutes and has been driving fine ever since. I have an appointment with the dealer this week. Anyone knows if there is a specific version of software (with the fix) that I should ask the service center to check and update to?
