I've had my 2009 Accord EXL V6 into the shop 5 times now due to a misfire on cylinder 3 (code P0303). I've had a fuel injector replaced, the engine computer replaced and most recently, the valve seals (which was supposedly the final solution although I experienced the problem yet again). Honda couldn't find anything wrong with my car after the last breakdown and actually gave me my car back with no repairs. I lobbied Honda to repurchase my vehicle but instead I've been left to wait for the next breakdown for Honda to take additional action. I'm disappointed with Honda beyond words. I've heard from dealers of some similar misfire complaints and I wanted to warn potential buyers. Has anyone else experienced this?
