I have recently noticed that the car feels a bit odd when cruising at motorway speeds. It's quite hard to explain but it just feels like I am been moved from side to side in the cabin when the car is on a flat straight road. Steering wheel isn't moving left to right either.

Anyone experienced anything similar / have any ideas?

I got this as well on the motorway.
I put it down to ruts in the surface as it only happened to me on the inside lane. RRS HSE Dynamic SDV6 2014

Exactly same for me Current - 2020 Range Rover Sport P400e
Gone - 2014 Range Rover Sport HSE SDV6
Gone - 2017 Audi A8 Sport
Gone - 2007 Range Rover Sport HSE TDV8 - Great car.

Must just be something I only notice from time to time then. Hopefully it’s normal, or we all have broken cars!

definitely truck ruts in the slow lane....next time you get this vague feeling move to the second lane and i'll guarantee the drive will improve..

Thanks! I will give it a go. Will be pleased if it’s nothing. Guessing the track is just wide enough to get pulled between the ruts

Haven't had this in the Range Rover but definitely when I had my Omega a few years ago, you could actually see the grooves in the road where HGVs had worn the surface away.
