Its been a long time since I commented on this topic (2 1/2 years actually) but I've been keeping tabs on it regularly. Luckily I was able to dump my 2014 in April 2015 for a new Ram. I owned two of these trucks and both were vibrators. One of our company trucks is a 2015 and its a vibrator. Hell I've rode in quite a few of these trucks and they all had vibration issues. Anybody that says that this is a small problem that only affects a few of these trucks is crazy. Anytime I run across someone talking about buying one of these trucks I always do my best to talk them out of it. The size of this thread has probably doubled since my last comment on here which is totally ridiculous. I owned several of the NBS and NNBS trucks and granted they weren't perfect but at least the problems were minor and easily fixed. Good luck
