NHTSA Complaint #11432413 — 2016 BMW R1200 RS

Motorcycle Engine Control Unit (ECU) is experiencing control logic faults and forces the engine into low power "Limp Mode" operation. In my case, several of these events occurred at ~18,000-miles (May 2020) and the servicing could find no mechanical or electrical problem. The manufacturer recommended re-programming of ECU. At 27,000 (July 2021) the same control logic faults (21F961 & 21F971) occurred again. Additional fault events and limp mode operation have occurred since. The transition to Limp Mode may protect the engine, but the rapid loss of engine power when traveling on multi-lane highways places the motorcyclist at extreme risk of being rear-ended by following traffic. In addition, in many areas, there is minimal berm.
