My 2011 Elantra has a slightly rough idle at stop lights. It doesn't happen ever time, and some people probably wouldn't even notice it, but at every few/several stops it idles a bit rough. When I recently had it in to Hyundai service for the ECM update, I asked them to take a look at it. Of couse, they couldn't replicate it at the time, so they couldn't do anything to address it directly. The service manager asked if it happens when the A/C is on or off. While I didn't know the answer at the time, it seems to happen with it both on or off. He did say that the ECM update may address/fix the issue, but unfortunately it didn't. While it's not a big problem, it's a minor annoyance I'd like to get fixed (as I need to enjoy my ride at all times ^_^ ).
Anybody else notice this with their car and, if so, have you done anything about it? Any other suggestions are welcomed - especially from those who understand what causes the car to idle like that.
