Driving along at normal highway speeds and the emission management indicator light started blinking. Took vehicle to Honda dealership for inspection and found out that there was a software update needed for the fuel management control systems as Honda was getting multiple complaints of early spark plug fouling due to incorrect management of the eco drive state. We found out that we had lost 4 out of 6 cylinders due to the spark plugs being fouled. This could have been a serious safety issue and could have caused a major accident on a interstate highway had all the cylinders been lost at one time. Was traveling with wife and 2 kids at time of incident. To me there should be a recall for 2010 Honda Pilot as this is a known problem through Honda. The software update was still covered under warranty but the replacement of the plugs was not as they are considered a normal wear and tear item even though they lasted for less than half of the expected life of a spark plug.
