I've had my truck for a little over a month. I'm loving it (for the most part). However, my truck has had some vibration at highway speeds. I'm on vacation, and before leaving, I dropped my truck off at the dealer. It has about 1300mi on it, and I had done a test ride with the service manager a couple weeks ago. At that time he noted that on torque lockup it started up. They texted me today and say that it is going to need a new torque converter! They went to order the part and found they had one in stock. So, hopefully upon my return, it will have been replaced and the problem resolved. Crossing my fingers.
