I am filing this complaint regarding my 2019 Honda Accord equipped with the 1.5L turbocharged engine. The vehicle currently has approximately 190,000 miles. My vehicle has developed a serious engine/drivability problem accompanied by multiple warning lights. The warning lights that have appeared include the Check Engine light, VSA/Traction Control warning, Brake warning, Steering warning, Adaptive Cruise Control (ACC) warning, and Road Departure warning. The diagnostic trouble codes found on the vehicle are: P0300 – Random/Multiple Cylinder Misfire P0302 – Cylinder #2 Misfire P0303 – Cylinder #3 Misfire P219A – Air-Fuel Ratio Variation P0420 – Catalyst System Efficiency Below Threshold I took the vehicle to a Honda dealership for diagnosis. After inspecting the vehicle, the dealership told me that I need a turbocharger. I have never previously replaced the turbocharger on this vehicle. I am concerned that a major turbocharger/engine-related failure on a vehicle equipped with the 1.5L turbo engine, combined with multiple cylinder misfires and an air-fuel ratio variation, could create a significant safety hazard. My concern is not simply the cost of repairing the vehicle. I am concerned about what could happen if the engine suddenly loses power, hesitates, misfires severely, or fails to accelerate while I am driving in traffic or attempting to merge onto a highway. The multiple warning lights are also concerning. When the problem occurs, the vehicle displays warnings involving several systems, including traction control, braking, steering, ACC, and Road Departure. This creates concern that safety and driver-assistance features may be disabled or affected at the same time as the engine problem. The vehicle has approximately 190,000 miles, but I believe mileage alone should not dismiss a potentially recurring safety-related defect, particularly when the vehicle is experiencing multiple engine-related diagnostic codes and the dealership has diagnosed a turbocharg

My vehicle’s fuel delivery system failed after a recall repair. The in-tank fuel pump was replaced under recall by the dealer, even though I had no drivability complaints, no warning lights, and a full inspection that day confirmed no issues with my vehicle. Immediately after the recall pump replacement, the vehicle developed drivability problems including sputtering, hesitation, and failure to start.On one occasion, the underside of the car overheated and exhaust fumes, including carbon monoxide, entered the cabin. The interior filled with heat and fumes, I became lightheaded, dizzy, and shaky, and nearly lost consciousness while driving. My dog, who was with me, vomited and panted heavily from the exposure. I had to pull over and exit the vehicle immediately. This incident occurred only after the recall pump was replaced and points to faulty installation or malfunction of the recall component, which disrupted the fuel system and caused improper combustion and exhaust handling. On another occasion, the vehicle stalled in the middle of an intersection, leaving me at serious risk of being hit by cross traffic. The car now shows a high-pressure fuel pump fault. Although the in-tank pump and the high-pressure pump are in different locations, they are part of the same system: the in-tank pump supplies steady fuel volume and pressure directly to the high-pressure pump. If the in-tank pump is defective, mis-installed, or inconsistent, it causes the high-pressure pump to fail. This made my vehicle unsafe to operate, placing me, my passengers, and other drivers at risk. The problem has been confirmed by the dealership, which documented a high-pressure fuel pump fault, and reviewed by Honda Corporate. Components and service records are available for inspection. There were no warning lamps, messages, or drivability issues prior to the recall service, all symptoms appeared immediately afterward.

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (P0300–P030X). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a Technical Service Bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018–2019 Accord models with the 1.5L turbo engine. This should be investigated and addressed as a recall to protect drivers.
