2024 Lincoln Navigator tire problems

[FlightBlue24]

Any luck with all the troubleshooting steps mentioned in this forum?
At this point, I’m exhausted from brainstorming the issue on my own. What’s more frustrating is the dealership’s lack of effort to dig deeper and properly diagnose what could be causing this persistent vibration.
Now I’m also noticing rough idling (which was present since day 1 but getting more noticeable), which opens up a wide range of possibilities - vacuum seals or worn/bad engine mounts to the dreaded camshaft problem that plagued prior models.

It makes me wonder if these vibrations are just a continuation of the same underlying engine issues seen in earlier versions.

One word...Michelin!

Michelin! Roadforce balance!

I have the rough idle here and there on my 23 with 5k miles and wondering if this could be from a dying battery or something in electrical system?

Asking as when I detail my car, I have the doors open with the interior and door lights disabled and after about an hour I get a low battery warning from the app telling me to trickle charge it.

If those door activated lights are off what would be drawing on the battery?

I read on this forum from another user that it could be the wireless charger even though I've never used it or that some sort of electrical calibration/ reset needs to be done to stop it.

I just picked up my 24 Nav Reserve today since they couldn’t deliver it until the camera recall was addressed.

I immediately noticed the vibrations on the highway. It seems to start around 65 mph and gradually increases until it becomes extremely noticeable around 78 mph. The vibrations are enough to shake the driver side mirror to the point of distraction and it visually vibrates your arm via the steering wheel. Seeing as I was driving it home from out of state, I couldn’t take it back to the dealer and be stuck there, so I called them and informed them of the issue and planning to make an appointment with a local dealer. My sales rep mentioned the potential flat spots from sitting around for over a year (was manufactured August 2024). After reading this forum, I’m guessing I have the same issue. I do have the upgraded machined 22s.

Vehicle is great otherwise, but the vibration is going to be a problem if they can’t resolve it.

Sounds like no one’s had luck yet with a permanent fix?

So, I went ahead and bought new tires from the dealership to address the sidewall issue — Nitto Terra Grappler 3 (285/50/22). These are considered among the best tires for road force balancing, and my Road Force numbers were in the single digits. Unfortunately, the vibrations actually amplified tenfold. Now the tires are sitting in the shed, waiting to be sold off, since the dealership won’t consider taking them back even with restocking fee.
One thing I’ve learned from this experience is that the total unsprung weight of the tires and wheels is likely the cause of the vibrations. As others have suggested, switching to 20-inch wheels can reduce unsprung weight and improve ride quality. I also used an OBDII diagnostic tool to check damper current and damper solenoid resistance, which seem to be less responsive with heavier tires leading to vibrations.

Switching to flow-forged 20" wheels saved me about 20lb per wheel and made the truck ride much better. That said, I didn't have vibration with the stock 22" wheels either (I still use them in winter). So just changing wheels is unlikely to solve your problem. Look for loose/worn suspension components and wheel hubs. Unbalanced brake rotors is another typically overlooked cause of vibration.

I purchased a 2024 Navigator L in may of this year and had the vibration from 70 and above from day one. I was told to drive it 3 or 4000 miles to see if the tires work itself out bur that didnt help. Then they replaced with michelins which was worst, I had the wheels road force balanced by a professional tire shop after that and it was back to the same way the vibration was with the pirelli tires. The vibration is unbearable, after about 15 to 20 mins drive it makes the joints in my hand hurt. I took it back to the dealer on September 23rd and it is still there 2 weeks after with no resolution. They have tried new tires again, replacing the hubs and they said they disconnected the drive shaft, which I don't understand how they can test it for vibration after it's disconnected. I'm just reaching the point where I don't know what else to do with this 100k vehicle.

I’m really thinking it has to do with body control module/electrical system/camera calibration. I tried to testing for alternator which should show voltage above 13.8V per Lincoln specs, mine was at 13.5 consistently with all the electrical systems off, then I revved up the engine to 2000rpm, NO CHANGE. I asked dealer to check alternator, turns out he only checked for codes which I know were not there and said everything is fine.
1 possibility is if alternator is failing or belts are loose, it can lead to misfires of spark plugs and cause vibrations at different speeds/throttle response.
May be older navigators or the ones with no vibrations can check the voltage draw and compare numbers.

Is this the system that uses a camera to look ahead at the road surface and adjust the shock absorbers to improve the ride?

Misfire vibrations are totally different.

I know the vibrations for my 2024 Navigator is not an engine misfire... it is definitely speed sensitive and likely caused by combined tire/wheel/driveline issues.

Correct adaptive suspension with road preview. I tried resetting the module with the help of disconnecting battery.
What I have is the vibration which is present while idling especially when the AC is on and it continues to recur randomly at different speeds.
I’ve seen previous models having issues with torque converter where the plate separating torque converter was in contact with engine due to defective plates. I’m going for independent transmission repair shop to figure that part out.

Is there a chance the Adaptive Suspension with Road Preview can be malfunctioning at 50 times per second or 1000 times per second or whatever speed it adjusts the ride and cause what could be perceived as a vibration? Can the cameras/radar be paused, blinded, taped over, fuse pulled, to fully disable the system and then test drive??

The system is way too complex, it takes input from tire pressure, suspension solenoid resistance, body roll, throttle response and finally cameras. Im thinking of pulling fuse but then Im concerned if that would mess up the other connected modules.

Maybe just unplug each shock absorber unit so the system cannot actually influence the ride??
