Honda Civic check engine light comes on

Filed Nov 9, 2026 · Engine · TX

The cylinder head gasket on this 2016 Honda Civic Touring suffered an internal failure and breach, leading to progressive coolant loss, engine overheating, sudden rough idling, check engine warning lamps, and vehicle misfires while driving. The sudden loss of power and risk of engine stalling created an immediate safety hazard while operating in traffic on public roadways. The vehicle is currently held and available for inspection at an authorized dealership, where the service center confirmed a catastrophic internal head gasket breach. The failure caused extensive coolant intrusion and fluid emulsification inside the crankcase, which completely destroyed the motor's internal lubrication and subsequently starved the turbocharger bearings, causing the turbocharger to malfunction as well. This component failure matches the exact systemic defect parameters detailed under Honda Service Bulletin 26-099.

While traveling on the highway at approximately 55–60 mph, my vehicle suddenly began shaking and progressively losing engine power and speed. The check-engine light started flashing rapidly, followed by multiple dashboard warnings involving the braking system, power steering, vehicle stability control, collision mitigation, and other safety systems. Despite pressing the accelerator, the vehicle continued losing power and slowing down. The engine remained running, but the vehicle could not maintain highway speed.

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.
