Hi rt10516, To my way of thinking, Ineos should investigate what is causing this vibration and resonance at certain speeds and rpm. It is being reported enough by forum members to be an issue to many that needs to be further investigated and resolved by Ineos.
It should not be that difficult for Ineos along with BMW and Magna Steyr to pinpoint the cause of this and come up with a solution. A straight 6 is the most balanced engine design in the world, so they have a damm good starting point to start from and get to the the bottom of it.
The expectations in the US market I believe are higher than in many parts of the world as most of us were never exposed to an original Defender, which from everything I have read is a substantial compromise in ride quality and vibration. Coming from an original Defender or even a Jeep, a Grenadier is indeed a refined vehicle, however coming from some of the nice SUV like trucks, SUV's or a New Defender, the Grenadier is not as refined in ride quality as we are all aware and not expecting. We were however not expecting excess vibration and resonance as part of the driving experience. Yes, We in the US are winers and Yes I love Pinot too.
Early on in this forum I posted about excess vibration in one of the Range Rover Sports I owned. Feeling that vibration through the steering wheel quickly went from mild irritation to making it not enjoyable to drive at all. I tracked down the cause, (which I found on the Land Rover Forum), and had my dealer fix it. In this case, Range Rover had decided they no longer needed to install a donut shaped rubber vibration damper and left it off. The dealer thought I was a bit nuts and could not imagine that I knew what I was talking about, however after insisting they install it, they did and it 100% cured the vibration that I was feeling up through the vehicle and steering wheel. What an incredible pure rush of joy driving my vehicle back home from the dealer and for as long as I owned it. It completely transformed the driving experience. If you or INEOS, (are you listening), is interested in reading about this early post and the link to the simple cure, I have posted 2 links to it at the bottom of this post.
I am not saying something as simple as this would cure the vibration and it would likely not fix a resonance, as they may not be related, however perhaps Ineos should start here and investigate installing a simple vibration damper as if that would offset the vibration, it would be a super simple and low cost solution. If not, they need to chase these excess vibrations down and the resonance issue too and come up with solutions to those who are experiencing it. I know if my new Grenadier experiences excess vibration, and Ineos has not found a solution, I will be look at the possibility of installing a vibration damper on my Grenadier as a first step toward solving the issue.
Coming up with a solution to this issue and others that Forum members have found can only help sales and build the brand, something I know Sir Jim Ratcliffe wants or he would not have created this vehicle for himself and the rest of the world. We are all incredibly grateful he has put his time, effort and money behind this incredible vehicle and only want to see it succeed, improve and prosper. DaBull

Hi Ineos, There has been a lot of Grenadier owners experiencing vibrations in the drive train that is felt in the vehicle and through the steering wheel. I owned a Range Rover Sport with the exact same issue and Land Rover was able to cure it by installing a damper that they had left off. They...
