Yesterday on my way home a warning came on my display "Check Active Air Flap System." This is a system Hyundai used to deflect air flow at high speed to optimize fuel economy. From reading different forums last night, it seemed more common than it should be and when I took it to the dealership this morning, his expression was about the same. If this is an issue Hyundai should issue a recall and correct the problem.

Update from May 12, 2014: Dealer stated that AAF system failure was due to damage to front bumper from impact causing AAF to be knocked off track. The damage they are referring to happened over 6 months ago. $250 later, the AAF was cleaned, greased, re-aligned and replace. It is my belief that the service to repair should be covered under warranty and a better system installed in future models.

Update from May 12, 2014: Dealer stated "DTC P1235 AAF system fail. Found damage to front bumper from impact causing AAF to be knocked off track (see photo). Removed bumper and AAF and cleaned air flap guides and reassembled AAF." The damage he was referring to was a scrap from a curb that happened over 6 months ago and some chips from rocks from the roadway. If minor, everyday driving conditions are going to cause the AAF to jump off the guides, 1) it should be covered under warranty, 2) it should be reevaluated and reengineered to hold up better.
