NHTSA Complaint #11694992 — 2018 HONDA ACCORD

My 2018 Honda Accord Sport has experienced repeated engine and turbocharger problems related to a likely head gasket failure. For nearly two years, I had to replace the spark plugs every six months without ever getting a check-engine light. When I brought the vehicle to Hardin Honda in Anaheim, the dealer ran a test and said the head gasket was fine at that time. However, the issues continued, and eventually, the head gasket and turbocharger both failed. I can't spent about $4,000 in repairs, and I lost significant time without my vehicle, which affected my ability to work. Additional Details: Honda replaced my fuel pump twice. The first failure caused my engine to go into limp mode on the freeway, which was extremely dangerous and also damaged the turbocharger. Honda replaced the engine computer (ECU) only six months after I purchased the car. When I contacted Honda corporate, they admitted to being aware of this issue but said they would only offer reimbursement if a recall was issued in the future. Safety Concern: The sudden loss of power at highway speeds is a serious safety hazard. This issue appears to be widespread among owners of the 1.5L turbo engines, and many drivers are reporting similar head gasket and turbocharger failures. Requested Action: I am requesting a formal investigation into the 1.5L turbo engine design and related head gasket and turbocharger failures in 2018 Honda Accords. These problems pose a clear safety risk and result in high out-of-pocket repair costs for owners.
