2018 Honda Civic: sudden loss of power

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 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 engine gasket failed, leaking coolant into Cylinder 3. This created misfires while the vehicle was driving, leading to unpredictable loss of power while driving. Eventually, the coolant purged unbeknownst to the driver and created overheating conditions while driving which could have led to complete engine failure on the road. This behavior was confirmed and reproduced by an independent shop, WenMac Repair, in Hardin County, Ohio. They replaced the spark plugs and coils, thinking the misfire was not necessarily related to the head gasket. The vehicle was then taken to Honda Development and Manufacturing of America, LLC's official repair center for Honda Associates attached to Honda's Marysville Auto Plant 10/1/25 and diagnosed by a Honda master technician. My fiance and I both directly work for Honda. It is currently having the head gasket replaced at a cost of $2,700.00 plus taxes. The vehicle is still in the shop. The failure was observed on vehicle first around 150,000 miles.

Car threw a p0035 code which indicates a problem with the turbo bypass valve solenoid high voltage/circuit. Car suddenly lost power and had many service lights go off. The check engine light, power steering, brakes, stability, and other lights went on. This prevents my car from going over 40 MPH without feeling like the car is struggling to accelerate. The dealership couldn't reproduce or confirm the issue when I went in for service. The code will disappear and reappear after a few starts ups. I noticed that the 2017 type R has this recall but I'm noticing a lot of other owners having this issue as well.

I have scheduled and attended several appointments to have my fuel pump replaced as per the recall. The only dealership that is within 20 miles of my home (El Paso Honda 1490 Lee Trevino, 79936) keeps refusing to do the replacement. I have expressed that my engine is losing power when going uphill and when driving on I-10. They refuse because the check engine light isn't on. This recall has been in effect since last year and the dealership keeps blaming Honda stating they cannot order the part unless the check engine light is on.

Fuel injectors failed at 60,000 miles. I do have the failed injectors. The driver's safety was put at risk in the case of engine failure or an unexpected loss of power. This is a common problem documented by owners of the 10th generation Civic Si, other 1.5l turbo Hondas, as well as Honda itself. There was an emission light several weeks ago and an engine light a couple of days ago.

Driving on the highway and my check engine light starting to flash. I experienced loss of power and hesitation during acceleration. I got home and scanned my computer and it returned P0304. I then removed the #4 ignition coil and that's when I noticed rust. Seems like the seal on the ignition coil failed and water has been leaking into the #4 cylinder over time.
