I have read quite a few comments on here about the intermittent noise and vibration that happens with these 5th gen Rams. My truck also has the same issue, ever since I bought it. I’ve had it to two dealerships. The service manager even rode with me while it was making that noise, he then took his lead mechanic out for a ride. They had no idea what it could be and just sent me in my way with no explanation. I’ve also had issues with my truck’s brakes making a god-awful screeching noise while backing up. It only happens while backing up and applying the brakes. The service guys told me that this was “normal”. I’ve had several mechanics tell me it’s not normal. They refused to do anything about it. I also have similar intermittent noise everyday that gradually comes in lasts about 10 seconds then drops off. This repeats itself every ten seconds. I was told on the Ram owners Facebook page that it may be caused from an electronic noise cancelling device mounted on the frame. Can anyone confirm this as well as how to fix it? With all these problems, I hope Dodge does something about it.
