What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2025 BMW 430I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
While driving at highway speed on [XXX] 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 XXX. 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

From owner reports, verbatim
We were driving on a local road and saw the car ahead parked at the traffic light. We began to brake from a safe distance. The car began slowing but instead of coming to a full stop, the brake resisted, the car made an odd sound, and instead the car accelerated into the car in front of us. The Tesla in front captured the odd behavior of the vehicle on camera. BMW will perform diagnostics.
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.”
