Hi: So sorry to hear about your family member’s ordeal. Sounds v much like what happened to me. I was in touch with BMW NA and they inspected my car for a couple of weeks and informed me that it was ‘operator error’ that caused the crash and that no malfunction was found in the car. They would not disclose the codes that they had found. I was offered payment of my deductible on the insurance provided I would sign a disclosure for not discussing my case on social media. I am certain they are covering up for some malfunction on these cars. The more cases like yours come forward, the more they will be forced to admit liability.
I hope this helps. A lawyer in LA had a similar mishap that you mentioned. BMW NA had his car for over two months before telling him that there was no malfunction!! |

No way that can be the case with the 8-series as with my size 13 shoe plenty of separation between the break and accelerator pedals. Plus, our floormats are tied down. I'm far from a conspiracy theorist (generally debunk them all) but in this case it does sound like a coverup if a NDA is required to get compensation for at least an insurance deductible. |

I have a 23 X6M and a 23 M8C. Just got them. Both cars do the same thing….
Often, but not always when I start slowly rolling into the garage, and the back tires meet resistance coming in, the engine revs from about 500 to 1500 RPMs. Scares the crap out of me and wife. If I sit there for about 10 seconds with my foot on the brake, and don’t creep forward anymore, it goes back down to 500 and then I continue moving forward… If I was to try and creep forward at 1500 I know I would hit the garage wall as the car moves too quickly. |

I always make a habit of watching the P light come on before releasing the brakes. I just don't that button push to park. I do have issues with collision avoidance falsely triggering from the right side. I don't know if that will ever be fixed. Rob |

I follow the same ‘ritual.’ Always look for the P before releasing brake but on that fateful occasion, the sudden surge as I was approaching the front wall of the parking spot, I jad my foot on the brake and not the accelerator for sure!!

Question does the M850i when you put it into park take like a second and you feel the vehicle disengage into park (a slight movement and sound of rpm drop)? My M8 does this when I am parking slowly and carefully into a tight spot. I place it in park and I feel the car drop into P and the rpm drops just a bit.

Nothing on my end with the M850GC. I park it daily in my garage and always drive slowly as I have a lot of stuff around.

Do you still feel safe driving the car after it was repaired? Mine is getting fixed currently, but I'm not sure I'll ever be able to trust the car with my family in it since it took off on its own. Does anyone have a take on why it mostly appears to be 8 series models having this issue? My theory is that this could be from some kind of fault in the driver assistance features such as the parking assistant or collision avoidance/ braking systems and that these systems are overriding driver input at inappropriate times. However, I would assume all BMW models this age would use the same electronic systems, especially in the higher-end V8 cars. I would think that an X5 M or a M550i or an M8 etc. share most of their driver-aid components and have similar drivetrains, so I wonder why it is mostly happening on the 8 series. Finally, mcscarna, would it be possible for me to get in contact with the lawyer in California that you mentioned? I would like to hear their take on how to handle this. We fear that we will be stuck with this car that nobody feels comfortable driving. |

It's not just the 8 series that has issues. Some other models have had issues with the forward collision mitigation suddenly slamming on the brakes. The issues with my car does not generate any fault codes so the dealership has no idea how to troubleshoot or even fix the issue. They can just throw parts at it and hope that fixes it. I'm actually surprised they cannot audit the sensor logs to show how many times the system is triggering. I keep asking my dealership to escalate the issue with BMW, but they just seem to drag their feet. In a week I will drop my car off for the 4th time and this time I'm just going to say I don't want it back until it is fixed. Rob |

Rob, why don’t you contact BMW NA directly. This is definitely a major safety issue. If they cannot fix the issue, they should cut you a deal on a new car.

I did try emailing BMW Canada, but the people reading the emails didn't seem to understand what I was trying to tell them and they just kept referring me back to the dealership. Edit: emailed BMW again, asking them to be involved since I consider the car faulty. Rob Last edited by Rob_G77; 09-17-2023 at 06:45 PM.. |

I'm in Canada as well.
End of 2000, I bought my first BMW a 2001 740i sport, at that time I think BMW was the only car with navigation. I had a problem with the NAV, was acting weird and the dealer for weeks trying to figure it out the issue but they couldn't! I called BMW Canada, they sent their rep to the dealer, took the car for a quick test drive, came back and asked to have it for few days. The issue was repaired within a week. |

Rob, whey you call this time, ask to meet with their rep to discuss the issue. They will send someone to the dealership.

AFAIK the main difference between the 8 and others is the electrically powered brake-by-wire system. For what people describe here, this might as well be the source of the problem.
So we have brake and accelerate by wire - a recipe for disaster. |
