Yes you really need to check the rear seat cowling when you take off. My finace worked for the dealership that I got it from and a week after I got it I told her it was really hard to get it to snap down and lock. She was like, noway. So she took it off and put it back on and I tool off with afriend of mine and about 1/2 mile down the road I felt something hit me in the back and when I looked back there it went flying into traffic and getting run over by cars. Needless to say she bought me a new one. The moral is to always check it twice, or three or four times.
