How many of you still have lane assist correction still turned on? I have it set to vibration warning only. The physical steering correction is too intrusive.

I have mine on and it doesn’t wander. I only had that issue for about 2 days and blame my self for it, I needed to get used to the sensitive steering.
I also installed spacers the next day. Not sure if that helped.

Agreed with other sentiment, its twitchy as hell and you need to provide frequent steering input. Adds to the experience.

First day it was wandering but as soon as i turned off lane assist (steering wheel intervention) it was perfectly fine.

It’s those absolute shite contis. Surprisingly Stiff/high spring rate sidewall tires that like to tramline. I changed them after a few weeks to 265/295 pirellis. Slightly softer sidewall but less tramlining. I don’t think the guys with Michelin’s have the same issue. I should add the contis are Very hard compound.

Also had a couple F90s; better overall rack. Slightly smaller steering ratio in the x3m. Main issue is Bmws LKA is not as refined as other (Jdm) manuf IMHO.

even when it’s off I never liked addl “dead weight” that it adds to the steering. Perhaps the system is designed for autobahn speeds. It feels worse on this chassis with its smaller rack and higher CG imho. I miss the M5 only because everything else feels slower after getting out of it. X3M downshifts smoother overall for an 8MT

I have same but have the issue. I strongly believe it depends on road surface. Any imperfections are readily apparent. Good smooth road, no issues. Any variation and it's pulling here and there. Primarily an issue with lumpy or troughed roads for me.

depends what you are used to, the new electronic steering sucks compared to the old hydrualic systems.

For those who already commented that this is happening. Is it under heavy acceleration and at what speeds? Under 100mph or over?
I only have the 19"RFT and I noticed this too but after break in and I was a little concerned.

Not sure that's it. My X3MC is the hardest modern vehicle I have driven to keep centered, other than my JL Wrangler, which has a entirely different steering/axle setup.

For me, it's at a steady highway speeds cruise (65mph+) - normal driving.

Wrong forum. We're talking about X3M which doesn't have 19s or RFT and has different suspension and steering.

Hasn't been an issue for us. Mine @~7500 miles with Michelins 33/38, or my wife's @ 3400 miles with Contis 33/38. Usually Sport/Sport/Sport settings. And this has been through all types of roads. I will say when I made the trip to SC for M School, I believe going through ATL there were some Interstate portions with grooved surfaces where I felt the tracking IIRC, but that was to be expected.

As long as you're sure the alignment is correct, and tire pressures are confirmed manually with the TPMS, and you've tried Sport/Sport+ steering on those roads, suspect it may a road surface interaction rather than a primary X3MC issue. See how it plays out on a variety of routes and give us some feedback.

Same issue here, but with regular X3 with standard Michelin's RFTs, under 1000 miles still.

Feels like there's no center spot at all, and constant corrections needed on any speed. Initially I thought it's alignment, brought to a dealer, they checked said OK, but never gave any specs, suspect they just get a lot of such complains and don't want to bring BMW another lawsuit.

I haven't had any issues with you. Have you guys tried that new Istep upgrade that is said to improve this?

Look at the PSA thread in this forum. That update does help a lot. It's a dealer performed update. It greatly improves a lot about the car, one of those things is the lane keeping assist.

I am unable to find. Can you please reference. I am not aware of a software update specifically to address the issue you guys have stated.

It was literally the top post in this forum...it's been there for like 3 weeks or so.

PSA: Those with a 2020 on older software get a update https://www.bimmerpost.com/forums/sh....php?t=1808564

I think he was looking for proof that the update addressed his specific concern. I think I read that BMW doesn't publish exactly what the software update does so you will have to rely on owners' reports.
