They all have problems, no matter what you buy, some problems are worse than others, however, when the problems are happening to you and your truck it makes it much worse!
I have a 13 longhorn....love it.....but it's had and having it's problems. Air Suspension will sometimes raise on it's own OR will not raise/lower when the button is pressed, even though it's says it is on the dash. It had a rattle on the passenger side, took it back to the dealer to find out it had a broken body mount they figured it arrived that way from factory, the rear view mirror does "sag" at first I thought it was imagination but no it really does move on it's own and the truck is going into the shop again tomorrow because the right rear signal light seems to work sometimes and not other times so it is being looked at by the dealers electrical mechanic
With all that being said.....I love my truck! It rides like a dream, handles great, tows the camper great (with good fuel mileage towing)
Anyone that is having problems and not getting service....I hope things change for you because, unfortunately, you never know when you buy a new (or second hand) vehicle what you are getting
