My 2011 GT with 17,000 miles on it just failed an emissions test. Has anyone else had problems with this? The guy at the facility asked if I'd had it in storage - no - I drive it at least once a week. I'm bringing it to the dealer tomorrow but just wanted to hear thoughts. Thanks.

Don't they tell you what part failed or do they just let you guess? A very low battery could cause a not ready for test issue.

Apparently the tester wasn't able to find about four different things he was looking for. I'll go get the paperwork later and let you know.

Do you have a custom tune?

Most common problem is sensors that are turned off in a custom tune, such as the rear O2 sensors

How recently had the battery been disconnected or dead?

Also, did you drive it far enough before you stopped at the Inspection Station?

drive it for a full week and then go back for a retest

What Bert said.
Is the car tuned?
I had an issue with my car going OBD-ready on the O2 sensors and the cats, the tuner did a revision and I was ready later that day.
