Just throwing it out there: My 2013 LR4 from day one had vibration coming in at certain speeds, mostly above 50 or so and it would get really worse as you'd go up to freeway speeds, with vibration coming in thru the steering wheel that you could feel in your forearms
Had the alignment done and the wheels balanced multiple times to no avail. I/dealership(s) were still trying to figure out but then by accident I ended up reading a section in the Handbook about the flat spots in the tires caused by the vehicle parked for long times with low tire inflation. It was like a light bulb went on. The handbook also said that the flat spot would go away after several hundred miles, etc.
Sure enough, the vibration started to diminish, and after a few hundred miles, it was completely gone.
The flat spot could have been caused by the car parked at the dealership lot or during shipping with very low inflation.
I have noticed that if it is really hot out and the car is parked in the sun for a day or or even several hours, and I'd start driving again, I would feel similar vibration for a few miles/time and then it would go away. And this is with the correct tire pressures
This truck is just one heavy beast
