All 1 Known Issues
On the 2015-2026 BMW M4, both F82 and G82 M4 models can develop rear subframe cracks when subjected to aggressive track use, particularly with sticky tires and aggressive suspension setups. The subframe mounting points and cross-members can crack under the repeated high lateral and longitudinal loads experienced during track driving.
Common Symptoms
- Clunking from rear over bumps
- Rear-end looseness or wandering
- Visible cracks at subframe mounts
- Uneven rear tire wear
- Creaking noises during hard cornering
- Rear alignment won't hold spec
How to Fix
Inspect subframe mounting points and welds regularly if the car sees track use. Reinforce with aftermarket subframe reinforcement plates or weld-in gussets. Severely cracked subframes must be replaced entirely. Upgraded subframe bushings (solid or reinforced) help distribute loads more evenly.
