I traded in my 2015 Sierra for my 2016 Ram Rebel with 18,000 miles on it. I had big concerns about this expensive air suspension, and added a 125,000 mile bumper to bumper warranty. So, after a few weeks of ownership I went to leave for work and see the front end all the way down. It would not raise back up despite show the "raising" like constantly. Off to the dealer it goes, and I'm told I'll probably not see it for weeks. I just had that bad feeling that this would happen, and damned if it didn't. I have a loaner car, but I'd much rather have my truck. I hope they can fix this thing right and relieve my paranoia that it's going to be a a recurring problem. I hope not, I really like the truck but this has left a bad taste in my mouth for this air suspension..... Sorry, had to rant a little bit...
