Bought brand new, ran perfectly. Had side rails, roof rack and trailer hitch installed by the dealer. Since then, a MAJOR loud vibration appears to come from the rear, but also sounds like it could be the engine and the sound is cascading. It isn't at slow speeds, isn't at idle, and once it starts around 40+ mph, even slowing down it remains until you get to about 20mph. Yes I'm trying to get it back to the dealer but am wondering if anyone's heard of this?

 

My 2017 has the factory running boards, factory roof rails and crossbars, and factory trailer hitch which was installed by the dealer, not by the factory. I have no vibrations or noises of any kind.

 

@ponderosajack . I don't think it's related either, just coincidental with post install. It feels more like an engine or drive train vibration, since it is explicitly from 45-55mph...

 

Sounds like drive train, torque converter has been an issue in the GM line and this sounds similar.

 

So it turns out the roof rack I had installed (factory) by the dealer is "not perfectly meant for the d5 even though Land Rover says it is...and the guys that installed it at the dealer didn't handle some of those finer points" :-) Dealer redid it and it was resolved. Here was the sound...and here is the rack.
