On "reduced" vs "early" lane assist setting, this could very well be the traditional German terminology "precision" (or just BMW cultural "precision"). That is, "reduced" may very well be intended to mean that the system doesn't attempt to correct until lane departure distance is significant. It then corrects somewhat aggressively to get you back on track — the magnitude of this correction is what is being noticed and is disconcerting.
In "early" mode, the system likely corrects quickly, resulting in a smaller magnitude of correction and, thus, less objectionable. They should really have two controls: one for when the system kicks in (as it seems to be now) and one for rate of correction. It's the lack of the latter parameter that seems to be causing the objectionable system behavior. By the way, I am getting some interesting info on the original low temperature steering issue and hope to post a few comments soon ...

I've got a little more info on the cold temperature steering issue at the core of this thread. In summary,
- G05 X5 (and many others) are 100% steering-by-wire, so no matter what assist features are turned off, there is always sensors, actuators, and software between the steering wheel and the road - BMW misjudged the temperature-variable performance of the sensors throughout the steering system; specifically, the part of the system that compensated for temperature-variable steering feel was too aggressive - corrective changes are software-only; the sensors are well characterized and known, hardware (sensors or actuators) will NOT need to be replaced as part of this correction - corrective changes involve extensive testing as well as some element of safety and fuel economy recertification; hence the long time to release update - the update is scheduled for late July 2019

Leave it to BMW for not having their story straight;
I received a call from my service advisor today saying they just got a new software update to correct the cold weather steering issues. My vehicle will apparently be ready by end of day tomorrow if all goes smoothly... Not holding my breath quite yet as this is contrary to the info LexxM3 just posted, and also contrary to the info my SA gave me a couple weeks ago saying late June for the update. I'll update here as soon as I have my vehicle in possession - its been gone for 3 months, so I'm kind of excited! |

Has anyone taken a video of this so that we have documentary evidence of the issue so BMW will not be able to refute it.
I don't receive my car for another three weeks and I hope this is not an issue. |

No compensation Stinkyxy - I don't believe anyone with this issue has gotten any sort of compensation. BMW wanted to downplay the problem as much as possible from my experience.
I'm in Calgary LexxM3 - If I actually get the vehicle back tomorrow, it will be perfect testing conditions as to whether its actually fixed or not since we're forecast for sub zero temps and 10-15cm of snow on Saturday Loaner was an X3 FreddyBMW |

Same problem with two new X5s delivered to me and my wife over the last couple of weeks. I would describe our experience as overly aggressive "steering intervention" with the lane departure system. For example, if I drift close to a line on my left, the assist will activate, overcorrect (oversteer), kicking me toward the right side of my lane. In short time I reach the right line, the system activates again, and kicks me back to the left. My wife feels unsafe. She unchecked the steering intervention option in the lane departure menu. I spent $1,700 on this feature expecting a gentle nudge from the system back to the center of my lane relieving some of the fatigue of long drives. Instead we are experiencing dangerous feeling situations!

Clearly their validation failed to uncover this issue, which is indeed a significant one that increases the risk of driving the vehicle in the very conditions that we bought it for to begin with!

I am now getting "confirmation" that what is "suddenly" available now is a pre-production of the "late July 2019" update for this issue. In "quotes" because ... who the heck really knows except BMW corporate. An initial indication of "late July" release of this safety-critical update versus the now sudden current availability is disconcerting to say the least. It points to invalid info in the entire story as it doesn't make coherent sense per @gpitts comments.

I'm new to the site, not sure if I can post here, but does anyone use a dashcam in their G05? A BMW engineer took a look at my car last month and said all the problems were due to my dashcam...including the steering issues in this this thread.
Since delivery in Dec. 2018. My car spent over 50 days in the shop. And the problems I had were: Transmission malfunction error message; Gear selector error messages; Steering twitch in cold temperature; Driver's assistance system reduced error message; Parking assistance system reduced error message; BC button/instrument cluster/headup display not working 100%. I do not think all the those problems are related to a simple dashcam, that's plugged into a 12v outlet by the cupholders. Specially, it's the same dashcam I used in my 2018 X3m40i. The dash cam I use is Rexing V1P 3rd Gen. Any thoughts? |

Definitely not all related to the dash cam, many on your list of problems are known issues. You have a bad KAFAS camera which I assume they have replaced by now given it has been in the shop so long. If not, they should order one and replace it for you.
The BC button is an issue most/all of us have at times, just do reboot iDrive and that will go away. Last edited by TurtleBoy; 04-29-2019 at 11:02 AM.. Reason: Change "none" to "known" ;) |
