BMW 320i xDrive braking issue with noise due to low pads and rusted, scratched discs on BMW 320i xDrive

Some BMW 320i xDrive owners report experiencing braking issues, including noise from rust buildup on the rotors after the vehicle has been parked for extended periods. This grinding or scraping noise often indicates surface corrosion on the discs. Additionally, worn brake pads are a common cause of braking noise, and the appearance of a brake pad warning message on the iDrive screen signals the need for attention. Owners are advised to ensure that wheels rotate freely and to inspect brake pads for any sticking issues that could exacerbate noise problems. Furthermore, many owners have noted the importance of responding to brake warning lights on the dashboard, which can indicate low brake fluid or worn components; ignoring these warnings may lead to serious safety risks. Lastly, some owners should be aware of a recall affecting over 50,000 BMW vehicles due to a software issue that may compromise braking assist, highlighting the importance of staying informed about recalls to ensure vehicle safety.
