Has anyone had problems with their start/stop? I've now had my 2012 6er coupe for 11mo and have started noticing when taking my foot off the brake and it auto-starts back up, it sometimes seems to be very labored. A handful of times after this labored start up, it's even shifted into park... Not great, especially when the light turns green. Is this a known issue? Next time I make it to the dealer, I want to get the update that allows me to turn it off and keep it off for sure.
