Seems to be a common thing for Aleros. Driving on the highway and trim came off.

Dealer repaired molding that came off while driving. The problem is that it is not covered under any warranty. Unless you want to pay out the @$$, please submit a complaint to www.NHTSA.gov.

My windshield window trimming began to come off. at first it was just loose and i tried to snap it back on. this was a temporary fix. when i began to drive at a reasonable speed it start to hang off and it was noticeable. It finally flew off while i was on the highway.
