“Vehicle started sputtering, then all the engine lights came on. The car felt like it did not want to drive. Took it to the dealer for diagnosis. Dealer reported that the head gasket needed to be replaced. He stated that this is a known issue but that Honda has not issued a recall. The car only has $100,000 miles. Dealer said to call American Honda to see if they would give any "good will" money. They declined.”
