I used the heck out of the one on my 2011, and never had an issue with it in the 8 years I had it. I haven't heard a lot about this being an "issue", though I have heard one other person that this happened to. It's been a a while back, and I don't remember the year of the truck. I hope it is not an actual "issue", because this new truck sits way higher and we (my wife and I) absolutely depend on them to get us up in this truck.
