2024 Lincoln Navigator tire problems

I can't imagine "unplugging" the shock absorbers would work without wreaking havoc to the vehicle in terms of warnings and whatever system defaults may be in place.

For those who may not understand the working theory behind these types of shock absorbers, here is an AI clip...

Magnetic fluid shock absorbers, also known as magnetorheological dampers, use a special fluid that changes its viscosity in response to a magnetic field. When an electric current is applied, the magnetic particles in the fluid align, thickening it and allowing the shock absorber to adjust its stiffness almost instantly, improving ride comfort and handling.

Unplugging them in theory would likely leave the shock absorbers in a 'soft' state as the whole design theory relies on 'stiffening' the shocks on demand by magnetic force to the fluid inside the shock and depending upon the particular design, possibly affecting any variable valving inside the shock.

I don't think Navigators use magnetorheological dampers; GM vehicles (and whoever they licence them to) do though, and it's a superior design. I have two other vehicles with electronically adjustable shock absorbers, and in one of them disconnecting makes them soft, while in the other, conversely, stiff. So it's hard to say off the cuff.

In any case, vibration that appears at a certain speed is extremely unlikely to be related to shock absorbers. Testing that would be a wasted effort.

It would be great if there is a way to turn off/disable/stop the forward looking cameras or sensors from seeing the approaching road surface and therefore adjusting the ride (if that could cause the "vibration").

I cannot imagine how that system could cause vibration. But, if you insist, putting some masking tape over the camera should do the trick, I gather...

Have a 23 Navigator, was going crazy when i got it in April of 24. I've done all of the above Wheel alignment Etc. Its still a crap drive. Vibrates on any road and engine jerks upon lowering gears and slowing down. Seams like the dealers know about it and they just take it in and "address it" to make you feel good. Its a beautiful car its a shame it cant live up to its purpose "Luxury & Comfort". I learnt to live with it. Eyeing the Escalade next. Hope Lincoln actually reads these forums and addresses this.

I’ve tapped the cameras and no change was noticed on highway speed months ago. I removed Body control module fuse to see if that shuts down the whole system. To my surprise, the system keeps on operating normally with no fault codes and no change in the vibrations. Quite strange.
Interestingly body control module share common fuse with image processing module. There were no errors or problems with image processing at all with the fuse removed. Possible someone messed up the wiring, lol. That will be laughable if turns out that case.
To rule out transmission issue, I’ve had the vehicle run in Neutral at 70mph, no change was noticed.
The rough idling is definitely related to turning on the AC
my next target is the lug nuts, wheel bearing since every time I had independent road force balance, the pattern of vibration shifts from higher speeds to lower speeds and vice versa.

Can't buy a Navigator, can't buy an Escalade or Yukon with the 6.2 engine crankshaft failure, dont want an Expedition......
What a sorry state of affairs.

Seriously?

Planet Lincoln has had my car for a month and is trying to sell me on new tires, which I'm quite certain won't fix the issue. They are trying to blame it on my gravel roads. Been driving SUVs for 25 years (two previous Navs included: 20018 and 2021) on these roads and am beyond frustrated that's what they are blaming it on. Even claiming "we haven't heard of this." Really, because this thread alone has 5 Planet Lincoln customers on it. Has anyone moved forward with the Class Action Lawsuit? We would like more information on being included, if so.
