HA I love it when this service tech posts here acting like they're REALLY going to help.

I have the same problem with my 09 as well, my car is an automatic though. It's the funniest thing, it'll stop working for the duration of the time the car is on, then on the next or next few starts, it'll work like normal. It works more times then not, but still it's annoying as hell.

How long has it been happening for you? It seems like it just started for me around 6 months ago.
