NHTSA Complaint #11686624 — 2018 HONDA ACCORD

I attempted to start my vehicle's engine normally and the engine made a rough cranking sounded and then finally started. The dashboard displayed multiple warning messages immediately after: Emission system problem/avoid heavy acceleration and high speed/see your dealer, tire pressure monitor system problem/check tire pressure/see your dealer, brake system problem/brake performance may be reduced/see your dealer, brake hold system problem/apply brake when stopped/see your dealer, electric power steering system problem/steering assist reduced/see your dealer, vehicle stability assist system problem/reduced traction and handling/see your dealer, hill start assist problem/vehicle may roll upon brake release/see your dealer, adaptive cruise control system problem/see your dealer, collision mitigation braking system problem/see your dealer, road departure mitigation system problem/see your dealer. I was able to carefully drive and drop off the vehicle at the dealership. The dealership conducted an inspection and found "the check engine light was illuminated due to a misfire in cylinder two. The diagnosis has revealed that this is caused by a bad head gasket, which is allowing a small coolant leak into the cylinder. To address this issue, the technician is recommending the replacement of the cylinder head gasket and spark plugs. Additionally, the technician has noted that the fuel injectors are a known failure point and suggest replacing them as well while the work is being performed." Also, the service employee told me verbally that this is a common issue with the Honda 1.5 turbo engines and they see this all the time. I authorized the replacement of the cylinder head gasket and spark plus since the cost was covered under my existing powertrain warranty with Honda. After a week, the vehicle was released to me and working fine. My safety and the safety of others with a similar engine was put at risk due to no prior warning and the impairment of critical safety systems.
