What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2024 BMW 540I, 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.

I reserved this vehicle with a deposit on Oct. 26. At the time I was told the vehicle was under recall/stop sale for a brake issue and I would not be able to take delivery until the recall work was performed. On 11/5, I was able to purchase the vehicle after the repair work was done. After leaving the dealership, about a half mile down the road I received a message on the vehicle display which said "Brake fluid level low. Have the problem checked by the nearest service center." The message also advised that I could continue driving the vehicle. I returned to the dealership and the car was inspected for roughly 30 mins. The vehicle was released to me and the message was gone. I was advised that the vehicle probably needed brake fluid from the recall repair. On 11/7, while driving I received the same Brake fluid level low message from the vehicle. I contacted the dealership and drove to the dealership to have the vehicle looked at again. About a mile from the dealership, as I applied the brakes, the vehicle suddenly generated a number of messages including "Brake system malfunction, stop carefully. Do not continue driving". At this point the brake pedal fell to the floor. I was able to stop the vehicle by applying a large amount of force to the brake pedal and was able to get to a nearby parking lot. I was very lucky and I would have been unable to prevent a crash under many circumstances. The braking power was almost completely gone from the vehicle. I returned the vehicle to the dealership and they reversed the transaction. From what I read online, the symptoms I experienced were exactly the same as those who experienced the brake failure which led to the recall. This car was either not fixed correctly or (even worse) the BMW remedy for the recall suffers the same potential problem as the original recall. In the second case, I believe this is a very dangerous situation.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
