What 2025 BMW 430i owners say
Electrical system
On 8/7/2025, I pulled into my driveway very slowly, I didn't have my foot on gas as I just went to our dumpster, and pressed the brake, I through the car was off, and went to exit, instead the car suddenly accelerated i tried to break, but the car didn't stop and smashed into my garage. It is at the dealership, Wesley chapel BMW, they sent me a message that it won't be ready today because there is recall and an issue but they have not told me what it is. I was researching and i saw what's called "sudden unintended acceleration."
While driving at highway speed on [redacted] I went to put my windows up. Without touching anything else my seat moved backward and I was unable to reach either pedal. Fortunately I was able to maneuver to a point where I was able to regain vehicle control. Obviously this was a life threatening situation which could have been disastrous. There was no auto correction by the vehicle. This was reported to BMW of Barrington , IL and serviced on [redacted]. No specific explanation has been provided. This is just one of many issues with this vehicle that appear to be related, and escalating in severity. I can't determine how they are related, if at all. I don't trust the safety of this vehicle and am not convinced BMW to date has performed a complete root cause analyses from the date the vehicle was put in service. I have requested BMW replace this vehicle.
