Driving back from Paris last week and noticed a slight rattle at low speeds when usually it is silent. I ignored it and carried on. Then, fortunately back in England on the M4, thought I'd got a plastic bag caught under the car, then the alternator light came on - ignored that too - thought battery must be getting flat as that is usually preceded by random warning lights - like the SHAWD which came on next and then the CMBS. Got to my destination and the whole thing died - as I'm sure you clever people know - you can't even engage any of the gears with a flat battery. Crankshaft pulley had broken into its two constituent parts and the plastic bag sound was the belt dragging. AA Relay man brought me home and now waiting for the part to do the Japan to Belgium route to my independent Honda garage in Gloucester. He said he'd seen this occasionally on diesel CR-Vs but never on a petrol engine. I'm at 105,000 miles. Found a recent posting about an Acura RL with a bad crank pulley, so maybe a weak spot?
