My 2018 BMW M6 which cost me almost $90,000 suddenly lost its suspension balance and height. Driving got bouncy, axles lost balance, driving turned hazardous. It was diagnosed that , The Virtual Dynamics Management module was fried and defected. The replacement cost $2,571.40 which Irvine California BMW made the recommended repair. After revisiting and researching the root cause, speaking with BMW certified master technicians, with 50+ years of working on MBW cars said, they never seen this defect nor this module failed before. They shared that this looks like a design flaw, with no recall and no history. I sent a certified letter dated Dec. 22, 2025 to BMW North America CEO Sebastian Mackensen and BMW Global CEO Oliver Zipse. Unfortunately, both did not read the letter. I was told they are too busy with other things, which is appalling. The letter was passed to their customer relations. They shared with me and confirmed that although this defect is rare, they will not reimburse me the cost of the repair since my car is out of warranty. I am aware that the car is out of warranty however they should stand and held accountable to the quality of the module since there are certified technicians shared with me that could have been a design flaw. This is not a wear and tear tear. Even BMW Service acknowledged that fact, especially with the vehicle that has been driven 34,000 miles. I believe this is a Safety issue. Suspension drops, uneven load shifts, and potential next corner could roll. Again, BMW admits it’s rare—meaning they know it happens—yet they won’t cover it. That’s not quality commitment. Based on what they constantly advertise. That’s policy over people.
