No issues with garage door opener or rain sensing wipers on my '12 Titanium. Work as I would expect them to. Not sure about auto dimming mirror. I'll have to check it tonight.
All those little touches - things like the door handle lock/unlock, three flash lane change, etc - add up. Coupled with the overall quality materials and interior fit and finish (on my car at least), the car feels very upscale for it's size and price.
Would be a shame to go backwards.
