My vehicle has had a vibration at highway speeds between 65-75 mph since I purchased it. The vibration is annoying and at times I've had to slow down to reduce the vibration which I feel could become unsafe. The vehicle rides smoother than any other pickup I've ever owned at lower speeds, my expectations are for it to ride the same way at any speed. The vibration seems to be coming from the rear of the truck and can be felt in the seat and floorboard. The problem seems to worsen while traveling on highways with wide sweeping turns. I've taken it to the selling dealership twice, the first time they reported 2 of the tires were bad and were replaced. I took it back a second time for the same issue and was told they could not detect a vibration or find anything which could be causing one. The problem persisted so I took it to a different dealership. They balanced the tires, rotated them and claimed the problem had been resolved. The problem had not been resolved and if anything has gotten worse after the third attempt to correct the issue. I have seen this issue reported by others. I've had the vehicle at servicing dealerships 3 times and 2 separate independent national tire chains and the problem persists.

At speeds between 50 and 70 mph vehicle has excessive vibration that seems to be from the rear of the vehicle. Had tires balanced by a tire shop and problem persisted. Dealership replaced all four tires and wheels and the problem still persists. Informed dealership of tsb sb-16-001-1, which is exactly the problem I have. They informed me they've never heard of the tsb. Similar to other complaints filed and researched concerning rear vibration issues with 2015 Ram trucks.

2015 Ram 1500 sport 4X2 - when traveling on the highway at speeds above 65 mph, the rear end begins to vibrate/shake to the point controlling the vehicle becomes a concern. If you slow down it goes away but then comes right back when going 65 or over again. Vibration is felt in the seat but not the steering wheel or pedals. Was taken to dealership on 9/11 and tires were re-balanced. Dealership stated that fixed the issue when it did not. Going back to dealership on 9/28 to have it looked at again. This has been reported by many and needs to be fixed before someone loses control of their Ram vehicle and crashes. If I were to hit a bump it would be very easy to lose control due to the horrible vibration.

From day one I have had a severe vibration from the rear of my truck at speed above 60 mph it will vibrate the floor board and front seat and center console severely. After many discussions with Ram and the dealer have agreed to replace my good year sra 275-60-20 with a new set of tires same type. To rectify the problem they did so on 8-28-2015 9950 miles it has made no difference. I brought this tsb I found here on NHTSA id number 10056977 service bulletin no. 16-001-14 to thier attention they say they have never heard of that tsb I am very concerned because after some research on my own it seems there are a growing number of 2015 1500's with this same issue. It it needs to be moved to a recall because it could be a hazard waiting to happen and it could be causing other damage to the truck. I am going by the dealer today 8-31-2015 to see what they are going to do now, vehicles today are to expensive to have these type of issues mine has been going on for 10000 miles and no fix in sight this is my 5th attempt to get the problem fixed.

The contact owns a 2015 Dodge Ram 1500. While driving approximately 40 mph, the front driver side axle and other related components completely detached from the vehicle. The failure caused the vehicle to travel out of the lane independently and side swipe another vehicle. The vehicle continued to accelerate and came to a stop as the front driver side collapsed to the ground. The front driver and passenger side tires were positioned inwardly. A police report was filed. The contact sustained injuries to both knees, but medical attention was not required. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 2,000. The VIN was unavailable. Updated 10/06/15 updated 12/13/2017
