2018 Honda Civic fuel system problems

Filed Nov 2, 2026 · Electrical, Fuel system · CA

My 2018 Honda Civic LX continues to experience serious safety and drivability issues after the fuel pump recall repair was completed by a Honda dealership. The vehicle intermittently shuts off while stopped, including at drive-throughs and stoplights. When pressing the accelerator, it sometimes hesitates or fails to respond, with the RPMs not increasing as expected. It may then suddenly jerk or surge forward. I have also experienced hesitation and struggling when turning after coming to a stop. During these incidents, dashboard warning lights have illuminated, including the check-engine, electric power steering, traction control/stability, and brake system lights. These issues put my safety and the safety of others at risk because the vehicle can unexpectedly lose power in traffic, fail to accelerate when needed, or suddenly surge forward. This creates a collision risk for surrounding vehicles and pedestrians, especially at intersections and in stop-and-go traffic. The fuel pump recall repair was completed, but the symptoms have continued. The dealership has not resolved the problem. Whether the malfunction was reproduced or confirmed during inspection is UNKNOWN. The exact failed component is UNKNOWN. The fuel delivery system, fuel pump, throttle body, accelerator control system, engine management system, and related electrical components may require investigation. The vehicle and components should be available for inspection upon request. Some symptoms existed before the recall repair and have continued afterward. I am requesting an investigation into whether the recall repair adequately addressed the safety issue or whether an additional defect remains.

My 1.5L turbo had the error message "Emissions System Problem" appear on the dash. When I went to AutoZone for them to run their diagnostic, it threw error code P219E which is indicative of a sticking-open fuel injector-pushing raw fuel through the engine and venting toxic vapors directly into my climate control system. Premature fuel injector failure is a known issue on Honda's 1.5L engines, but they have failed to address the issue related to the fuel injectors for these vehicles, presenting a serious safety hazard for drivers of their vehicles.

My vehicle is currently experiencing severe performance defects that directly mimic the documented failures associated with the defective, improperly molded fuel pump impellers. Specifically, I have experienced the following symptoms: Engine Stalling: The vehicle has lost engine power or stalled unexpectedly while in motion, creating an immediate and severe traffic hazard. Hard Starting / No-Start Condition: The engine frequently takes multiple crank cycles to start or fails to start entirely, despite a fully functional and recently tested 12V battery.Erratic Power Delivery: I have noticed severe engine hesitation and a loss of acceleration power while driving at highway speeds.I understand that American Honda has recalled over one million vehicles globally for this exact Denso fuel pump defect. Despite my vehicle exhibiting all classic symptoms of a failing, low-density fuel pump impeller, my specific VIN is currently not showing as "active" or "eligible" on the manufacturer's lookup tool.Because a sudden loss of engine power while driving significantly increases the risk of a crash or injury, this represents a critical safety issue. I request that American Honda corporate reviews this data, coordinates a diagnostic review with an authorized dealership without a diagnostic fee liability to myself, and covers the complete cost of a replacement fuel pump assembly under the safety recall countermeasure guidelines.Thank you for your immediate attention to this safety hazard.

The contact owns a 2018 Honda Civic. The contact stated that the fuel pump was surging, and the vehicle was jerking while idling or while driving at undisclosed speeds. The contact stated that the vehicle stalled. The Check Engine warning light was illuminated. The contact stated that the failure was associated with the federal safety agency Campaign Number: 23V858000 (Fuel System, Gasoline), which was previously repaired. The vehicle was taken to the local dealer, where an unknown diagnosis was provided. The vehicle was repaired, but the failure reoccurred. The manufacturer was contacted and opened an investigation. The failure mileage was approximately 104,661.

The contact owns a 2018 Honda Civic. The contact stated that while driving the vehicle at an undisclosed speed, the vehicle jerked forward roughly and stalled. A check engine warning light illuminated on the instrument cluster. The vehicle was taken to a dealership, where technicians diagnosed the issue and replaced an evaporative emissions (EVAP) sensor. Despite this repair, the symptoms persisted and the vehicle continues to experience rough jerking and stalling, but the waring light no longer illuminates. The contact referenced the federal safety agency Campaign Number: 20V314000 (Fuel System, Gasoline) however, the VIN was not included in the recall repair. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 105,007.

After Honda Safety Recall 24‑027 (“Replace the fuel pump motor”) was performed on my 2018 Honda Civic Si at an authorized Honda dealership, the vehicle began exhibiting fuel‑system‑related issues that did not exist prior to the recall work. Within one day of the initial recall repair, the vehicle developed hard‑start/extended‑crank behavior. The dealership later reported they had pinched an O‑ring during the recall work and replaced it. Next, I detected a fuel odor. After multiple refueling cycles to isolate the source, I reported the issue, and the dealership replaced an unspecified seal. Approximately one week after that repair, the vehicle developed a rich‑running condition and illuminated the check engine light with DTC P0172. On 2026‑03‑27, the dealership diagnosed the issue as failed fuel injectors and recommended replacement of all injectors, the fuel joint pipe, and associated seals. Their testing showed: EVAP system functioning normally; no induction leaks; MAF swap produced no change; fuel rail pressure at idle ~500 psi; and cylinders 1, 2, and 4 running rich relative to cylinder 3. Because the fuel system was disassembled multiple times immediately before the onset of the rich condition, and because the dealership acknowledged that contamination during recall work could plausibly cause injector malfunction, I am concerned that the post‑recall defect may be related to the recall procedure or subsequent rework. The dealership's alternative rationale was that fuel injector failures are so common on this platform that the failure was coincidental. That would imply the need for a fuel injection system recall. I am submitting this complaint because the vehicle developed fuel‑system performance and emissions issues only after the recall repair and subsequent rework, and the root cause remains uncertain. I request that the federal safety agency document this case and evaluate whether the recall procedure or related components may contribute to downstream fuel‑system failures.

We got notified of the recall by mail in early 2024. We called the Honda dealership in our locality, First Texas Honda (3400 Steck Ave, Austin, TX 78757) about it and they said the parts weren't available yet, and was estimated to be ready by Fall 2024. In July 2024, we were driving on a highway and the accelerator stalled as we reached 80 mph, with the check engine light flashing. Cars around us had to swoosh left and right to avoid colliding with our stalled car. By extreme luck we were able to use the car's momentum to safely exit the highway. Upon restarting the car, power was restored and the check engine light didn't illuminate again. There was slight shuddering in low gears. We made an appointment at the same First Texas Honda mentioned above to fix the problem, but after inspection they insisted that the problem was caused by loose battery cable unrelated to the fuel pump recall. Charged us $225 for the inspection and denied to replace the recalled part. Their predatory practice should be illegal and we are so disappointed in the system.
