The car hesitates upon acceleration and when it “misses” enough it will flash the engine on the dashboard, and not allow any further acceleration, going into “limp mode”. All the safety controls error on the message center and dashboard warnings all come on, even though it’s only the acceleration/transmission that’s affected. Not sure if it’s fuel injectors or a computer issue, but it’s absolutely dangerous upon entering a highway and hoping to not have system failures, that result in limp mode. I’ve been carrying a 10 mm socket for disconnecting the battery and rebooting the system, when needed. It only helps for a short while.

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

Head gasket needed to be replaced. Coolant leaking into cylinders, sudden loss of motive power / engine misfires while driving. Driving on the highway, and trying to accelerate, there is a hesitation and vibration and also when letting off the gas.

I am reporting a suspected head gasket/engine defect involving my 2018 Honda Accord Sport. My vehicle experienced multiple engine-related problems before ultimately requiring head gasket replacement and cylinder head repair. On July 27, 2024, at approximately 161,480 miles, the turbocharger was replaced. In September 2025, at 207,539 miles, my vehicle was serviced at Joe Morgan Honda, an authorized Honda dealership. During that visit, the Honda technician documented that the cooling system fluid level was low and that no external leaks were found. The technician documented that they suspected the head gasket was causing internal coolant loss over time. I was instructed to monitor the vehicle and was provided an estimate of approximately $4,400 plus tax for head gasket replacement. I specifically asked the Honda service advisor whether the head gasket could be repaired at that time or whether anything could be done to prevent the suspected problem from progressing. I was told there was nothing that could be done at that point other than monitor the vehicle. Within weeks, multiple warning lights illuminated on my dashboard and the vehicle began experiencing significant drivability problems, including hesitation, misfiring, and loss of acceleration. The loss of acceleration was particularly concerning because the vehicle did not respond or accelerate normally while being driven. I took the vehicle to Integrity Automotive on September 25, 2025, at 208,583 miles. The engine was checked, and the ignition coils and spark plugs were replaced. Despite those repairs, the vehicle ultimately required major engine repairs on November 8, 2025, at 210,230 miles. The cylinder head gasket was replaced and the cylinder head was serviced/repaired. The fuel injectors, spark plugs, and serpentine belt were also replaced, and the cooling system and drivability/performance were checked. Only approximately 2,691 miles elapsed between the Honda dealership documenting the suspected i

I own a 2018 Honda Accord LX 1.5T. The vehicle has developed an intermittent hard-start condition after sitting overnight. The engine cranks for approximately 5–6 seconds before starting and runs very rough for the first 2–5 seconds before smoothing out. Warm restarts are normal. While driving, the vehicle hesitates and stumbles during acceleration, is slow to build RPM, and fuel economy has noticeably decreased. During one hard acceleration event, the vehicle lost power and the check engine light flashed. I also observed that if I turn the ignition on and allow the fuel pump to prime for several seconds before starting the engine, the vehicle starts noticeably quicker than if I start it immediately. This makes me concerned that the fuel system may not be maintaining proper fuel pressure after the vehicle sits. Because of the hard starting, hesitation, intermittent loss of power during acceleration, and the improvement after allowing the fuel pump to prime, I am submitting this complaint for investigation because these symptoms could create a safety risk when entering traffic or accelerating.

The contact owns a 2021 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle decelerated and was hesitating while accelerating. The vehicle was taken to the dealer, where the spark plugs were replaced. The contact stated that months later, the vehicle experienced the same issue and was taken back to the dealer, where it was diagnosed with a blown head gasket. Two months later, the spark plugs were replaced again. Another two months later, additional components were repaired. The vehicle had been at the dealer for several months and the technicians were unable to determine the cause of the failure. The low engine oil warning light was illuminated, even though the engine oil level was not low. The dealer was unaware of the cause of the failure and stated that the engine needed to be dissembled for further inspection. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 133,000.

I am reporting a fuel pump module failure that has caused several drivability and safety concerns with my vehicle. Prior to the failure, the vehicle experienced intermittent difficulty starting, extended cranking before the engine would start, and occasional hesitation during acceleration. At times, the engine would lose power unexpectedly while driving, causing reduced performance and creating a potential safety hazard in traffic. The vehicle also experienced rough idling, sputtering, and instances where the engine stalled without warning. In some situations, the vehicle failed to start altogether despite having sufficient fuel in the tank. These symptoms became progressively worse over time and are consistent with a failing fuel pump module. Due to these issues, the vehicle became unreliable for daily transportation and posed a risk of sudden loss of power while operating on public roads. I am requesting that this failure be covered under the applicable fuel pump recall and that any related repairs and expenses be reimbursed or covered accordingly.

Pulled off my street to go to work, and the car engine started hesitating, misfiring and losing power. I turned around and was able to get it to a safe location, but had to have it towed to the dealership. Dealership ran codes said it was a bad injector issue and quoted me $2,600 to replace all 4. My Accord just turned 9 and has had all recommended services done. This is my 4th Honda and have never had any fuel injector issues with prior cars. My car is not showing as part of the recall for this, but it should be because they are defective. If I had not turned around, a semi could have hit me as I was in an industrial area, because the car all of a sudden lost power. This is an extreme safety issue and should be recalled.
