NHTSA Complaint #11485484 — 2014 BMW R 1200 GS

Rear drive shaft universal joint failed causing the motorcycle to lose power to the rear wheel. If I had been in a turn when the motorcycle lost power, I could have lost control of the vehicle, and my passenger and myself may have crashed and been harmed or died. Per BMW: There have been a mounting number of instances where condensation within the hollow swingarm unit has caused corrosion to accumulate on the drive shaft and/o rear u-joint, creating issues that can include loss of power to the rear wheel. BMW has now a Service Action SA 0033130000, to correct the condensation. No inspection other than by me mechanic. No warning lamps or messages prior to the failure. Symptoms prior to the failure were a strange vibrating sensation and hum emitting from the rear of the bike. This began 2 days prior to the joint failure. I believe condensation in the swing arm caused the corrosion that led to the failure of the drive shaft rear universal joint.
