What Happened
The receiver audio module is a computer chip that helps your car alert you to safety features like seat belt reminders. In some cases, this chip in your 2019-2022 3-Series or 4-Series vehicles might not work properly, meaning you won't hear the usual seat belt warning sound.
Risk if Unfixed
If the warning sound doesn't go off, you won't be alerted to buckle up, which increases the risk of injury in a crash. This is a serious issue that affects your safety on the road.
Free Fix
Your authorized BMW dealer will update the receiver audio module software for free. This update will ensure your seat belt warning sound works correctly, and it's a quick and easy fix.
