“CRANK HUB SPUN TIMING SPROCKET CAUSING VALVES TO IMPACT PISTON AND CATASTROPHIC ENGINE FAILURE. QUOTED MORE THAN $10K OUT OF POCKET TO REPAIR. THIS IS CAUSED DUE TO POOR CRANK HUB DESIGN. CAR COMPANIES HAVE BEEN USING KEYED CRANKHUBS FOR GENERATIONS BUT BMW DECIDED TO NOT USED A KEYED HUB.. THIS IS VERY NEGLIGENT CONSIDERING HOW MANY OF THESE VEHICLES HAVE ENGINE FAILURE DUE TO THIS.”
