Rocky ride

Vladimir that sounds like a good plan the car was bought for my wife to replace her rx300 o4 plate she had read all the reviews and having had several lexus vehicles before we just took it as a given that there would be no problems but everything is excellent except the sideways jolt yes it’s quiet in normal level mode yes it takes road humps easier than the older model but it’s not as comfortable we will try another premier can I as what was your problem with the is300 h ? Was it similar with the side to side ride ?

Hello John and Rayaan thank you for the replies yes I agree that the road noise level when driving in normal mode is almost non existent in lower mode it does increse but it was a very firm ride and where you gained on the side to side motion you lost with the thud of the bumps maybe it’s just one of those cars I agree it is excellent in every other way ....my ls 430 also has air suspension agreed it is lower body but it is a. Totally different drive experience. My initial thoughts were its just because the tyres are bigger than the older rx300 we changed it for my thinking was the extra tyre wall would cushion the drive and stop this side to side motion... however if the factory set up is for a stiffer body as Colin has pointed out then maybe it is just something we will have to live with. I am curious John what size wheels do you have are they also 19 inch?

Hello Colin thanks for the advice went for a drive in low mode .....yes a much stiffer ride less side to side motion but you do feel the potholes more. It did seem to be a similar ride to the rx300 but slightly more road noise and more feeling the road undulations through the seat......sounds stupid but I miss the RX300 yes it was noisier and had less gizmos eg HUD Bluetooth and less speakers but it’s definitely a case of you really don’t appreciate what you have until it’s gone thanks steve.

Hello Colin thanks for the reply we have been driving around in normal mode but we will give it a go in low mode having just re read page 322 onwards. I will let you know how it goes.

Thanks Peter well this is why we are confused some say that the higher tyre wall on the 18 inch will cushion the road bumps and others say that the 19 inch will stop the side to side jolt we are confused as the rx450 h is great on speed bumps but it does Want to jolt side to side which we did not notice in the Rx300 to this extent.

Hello I am new to the forum but have had several Lexus vehicles a GS300 was my first my present is a 2002 plate ls430 My wife had an Rx300 Sel 04 plate and she upgraded to a RX45H 13 premium, Now here is the reason why I joined.... the ride in the 04 rx300 was very comfortable however the ride in the Rx450 H premium has what can only be described as an excessive side to side movement even on minor road imperfections. My question to everybody is this because of the increased wheel size to 19 inch where as the o4 plate had 18 inch wheels it’s just that it seems to want to jolt you side to side however going over speed bumps are easier and more cushioned....by the way lexus say the car has no problems mechanically or otherwise..We look forward to your replies.....
