I actually thought that my winter tires weren't balanced properly.

But now I have summer tires on it and I still have the problem that the steering wheel vibrates at around 80 kph. This is independent of accelerating and the road surface. Simply rolling (out) is enough. This effect takes effect at 75-90 kph. The vibration is strongest at around 82 kph. The vibration also literally “floats” with increasing and decreasing intensity. However, I haven't noticed the effect with speeds above 100 kph.

Please note: It's a harmonic vibration in the steering wheel only, not the whole car is shaking.

I have a workshop appointment in mid-April.

For comparison: My iX1 (30) was built at the beginning of December 2023 (M Sport package, 18" summer and winter tires).

Thanks for pointing me in this direction. Just checked: I don't have that no. 7 on my December 2023 iX1 (Part Number: 31108859733). However, I got the mounting holes.

It says it should dampen 150 Hz vibration.

Do you think this will make a difference regarding my problem?

Update from my workshop appointment today:

Carried out two test drives, one with me, one without me. Problem acknowledged and found abnormal. They decided that they have no clue. An inquiry was made to BMW Munich to coordinate further action. Further instructions are expected from Munich at the end of the week, in the hope of finding out something “between the lines”.

Remarkable: The comparison vehicle from the yard was test driven (not by me). This one does not show this abnormality. However, the production date and equipment were not disclosed to me. So basically, the “state of the art” argument is not valid.

Experiences from other iX1 drivers appreciated...

I have an iX1 but never experienced this vibration. Hope that BMW Munich come back with some fix for you!

I have it at exactly 103-105kmh. It's worse when lifting off the throttle.

Mine is felt more through the body of the car rather than the steering wheel.

Local dealer reported no issue (to be fair, local limits are 100kmh, so they would need to test it on 110kmh limit country highway to test it without speeding).

That kind of shudder is a different one than mine. I am in contact with an Australian driver, who got her drive shafts (front and rear) and motors exchanged. That may have cured the 103-105 km/h shudder felt throughout the car. Her car was not part of the official drive shaft recall.

However, now she feels the steering wheel vibration at around 80 km/h, which I also experience. I don‘t have the whole car shuddering.

My dealer did not come up with a solution. The first thing BMW Munich requested was to update the software. I could image they lowered the power of the heat pump in order to fix one source of vibration. Now I haven‘t heard in a week after it obviously has fixed nothing.

I hope they know what to do next…

Still no solution for the steering wheel vibration at around 80 km/h (50 mph).

They exchanged the rear motor and tested another set or wheels (19" with Pirelli) instead of my 18" with Continental. Nothing helped.

Tires now shall be exchanged to Hankook on my 18" rims. No high expectation since my 18" winter wheel set got the identical problem with vibration with the same kind and intensity.

I must be something else. Munich is involved but obviously has no clue. Dealer test drove a new car from the latest production, same vibrations.

Could someone solve the problem?
