I just did a software update for my 2025 M3 and all settings were lost. Most of this is a customer inconvenience, but brake auto hold was turned off so imagine my surprise when I took my foot off the brake and my car rolled forward. Thankfully I was paying attention or there could have been an accident. I rely on auto hold to keep my car stopped even when my foot is off the brake.

The lane departure warning in my 2025 BMW M3 is in the form of a vibration alert in the steering wheel. However, even when the vibration alert level is set to the highest, most intense level, it is barely noticeable, and is virtually indistinguishable from ordinary road vibration felt in the steering wheel. I took this to the dealer and was told this is normal. This cannot be normal, and it could easily cause a crash because the driver is probably not going to feel the vibration alert. I have posted about this on bimmerpost and others have complained of the same issue with their BMW M3 cars: [XXX] Assuming this is normal as the dealer claims, or even if it's just a limited problem in some 2025 M3 cars, it is a safety issue because the point of the lane departure warning is to alert the driver that he is drifting into the next lane. I believe this matter needs to be investigated and perhaps a recall is needed. Also, I believe the BMW M4 is essentially the same car as the M3, so if the problem exists in many M3 cars, it probably also exists in many M4 cars. This would be a safety hazard that could result in preventable serious injuries or even deaths. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
