“While driving on vacation at approximately 2 hours away from home destination, there was a pop noise that was heard by all. Kept driving and all of a sudden the right side of the spoiler on the rear of the vehicle popped off and was hanging down. Tried to put back on, but would not go. Took it the rest of the way off, continued on our trip. When we returned home, we took it to a body shop, which the guy told us that we were the sixth person that has had this happen to them and they are going to be fixing it for us for a fee. …”

Did notice a creaking sound when opening tailgate early in the day. Looked and did not see any problems.”
