I am not sure WHAT component failed. My lights on my dash will not go off. I have done everything I was told to do, ever down to a new Battery. & they will not go off. My car will not go over a certain speed. Before this, there were no problems. No warning lights & it was driving perfectly fine. PLEASE HELP. When I researched this issue, I noticed a million others having the SAME problem. There has to be a recall on these Honda’s. Let alone, just a simple answer as to WHY…

My car starting shutting off on me suddenly while driving. No warning lights. Eventually had it towed to honda. Honda informed me it was the head gasket that blew with only 109,000 miles on the car at the time. My car had the 1.5 turbo engine that is now currently under investigation for this same issue. Ended up having a used motor put in it that cost me $4,000
