What Happened
The rear sub-frame in your vehicle is a critical part that helps keep your car stable. In some 2015-2017 M3 and M4 models, the bolts that hold it in place may have been reused during a previous repair, which can cause them to loosen over time.
Risk if Unfixed
If the bolts on your rear sub-frame come loose while driving, it could affect how your car handles, making it harder to steer and increasing the risk of a crash.
Free Fix
Your BMW dealer will replace the sub-frame bolts with new ones, at no cost to you. You should schedule this repair as soon as possible to ensure your car's safety and handling.
