2018 HONDA ACCORD Complaints

Transmission keeps malfunctioning from 1-2 and 2-3 gear shifts. Mainly prominent on the 2-3 gear shift having issues. Severe transmission jerk and sometimes slams into the next gear. This has been happening since I bought the car at 52k miles and it is currently at 62k miles. It can be available for inspection upon request. It also jerks on downshift. The transmission fluid has been drained and filled with Honda genuine atf 2.0 but the issue still persists after the service. The vehicle has not been inspected by the manufacturer. It has put my safety at risk because in low speed traffic my speed is unpredictable and I am worried of hitting a car in front of me. It is also an issue for vehicles behind me as well because the vehicle cannot find the gear and doesn't accelerate properly. When it slams into the next gear it seems to be a severe safety hazard for me and my passengers.

The vehicle experienced a catastrophic engine malfunction resulting in a no-start condition. The vehicle is currently inoperable and is available for inspection upon request. The engine failure caused the vehicle to lose power and become unreliable, creating a risk of breakdown while driving, which could have resulted in being stranded in traffic or an unsafe location and posed a risk to my personal safety and the safety of others. Yes. An independent repair facility confirmed the vehicle would not start and diagnosed the engine as failed. The vehicle was subsequently towed to another facility, where the condition was again documented. The vehicle has been inspected by independent repair facilities. The extended warranty company, Route 66, reviewed the claim and denied coverage based on their assessment. No inspection by the manufacturer or law enforcement has occurred. Prior to the failure, the vehicle exhibited warning indicators and operational issues, including overheating symptoms. These issues worsened over time and ultimately resulted in complete engine failure and a no-start condition.

Tachometer/speedometer screen completely black or dark. It will show the Honda logo and make sound. But once I’m driving or once the car is started it doesn’t show any rpm’s or the menu for miles, safety information or anything on that screen.

The vehicle experienced a rough idle and white smoke blowing out the exhaust on a cold startup. It did have coolant loss over a period of time with no visible leaks. I waited until I got a check engine code that revealed a misfire in cylinder 4. Upon further diagnostic testing it was revealed that the head gasket was blown between cylinders 3 and 4. I paid for the repair out of pocket only to see that this is a very common issue with the 1.5 turbo engine.

When I was accelerating the vehicle on 12/21/2025, a flashing check engine light came on, and the car started driving very roughly immediately, with an intense vibration. I noticed a lack of engine power, but the hybrid motor and battery kept me going for roughly 1 mile until they were depleted, after which I was unable to accelerate the vehicle. At that time, the car continued to decelerate, no matter how much I depressed the accelerator. I was able to safely pull over and turn the car off. I let it sit for one minute before turning it on again, at which point it behaved normally. I drove very cautiously to my destination, making sure to accelerate very gradually. This sudden lack of power put myself and others on the road at risk, as it was very sudden with no prior symptoms/warning lights, and I had no recourse besides pulling over as soon as possible. Over the next few days, I researched the problem online, and owners of Honda Accords from that generation (10th generation, model years 2018-2022) reported head gasket failure on all engines Honda offered the 10th generation Accord, including the 1.5 turbo, 2.0 turbo, and 2.0 hybrid engines. This problem is also reported on a slew of other Honda vehicles from roughly that time period. I brought it to Motor Werks Honda in Barrington, IL on 12/24/2025. After they completed their analysis, they determined it was a failed headgasket.

The A/C condenser on my Honda failed and leaked out all of the refrigerant, which subsequently caused the A/C compressor and related components to fail. This issue is well-documented, and Honda has issued an extended warranty specifically for the condenser due to its known defect. My vehicle was inspected by an authorized Honda dealership, and they confirmed that the condenser failed and that the resulting loss of refrigerant caused the compressor to generate metal shavings. These metal particles can circulate through the HVAC system, potentially entering the cabin and posing a health risk to the driver and passengers. Despite the clear causal relationship and the dealership’s findings, Honda is refusing to replace the failed compressor and associated components, even though the failure originated from a part they acknowledge as defective and have extended warranty coverage for. There were no warning lights, messages, or symptoms prior to the failure. The A/C system stopped functioning without any advance indication, leaving me without proper ventilation and climate control. This defect raises both mechanical reliability concerns and potential health and safety risks due to metal contamination within the HVAC system. I am requesting that NHTSA investigate this issue further, as Honda’s refusal to cover the full scope of damage caused by their known defective condenser leaves consumers exposed to unnecessary safety hazards and significant repair costs.

Blown head gasket at around 91,500 miles even though car have been kept up with oil change around 5,000k mile. It is currently in the mechanic shop as of 1/12/2025 awaiting repairs (parts are being order as we speak). So, probably can't have it inspected if requested unless it is soon. The random/early head gasket getting blown with not such high miles would have been devasting if I was driving on the highway. Since, it would cause the engine to over heat as the coolant is leaking into the engine piston and some case could cause lost of power on the highway. This problem seem to be quite common or expected as talking to the dealer and they were aware that a portion of these 1.5l turbo engine head gasket are getting blown. The vehicle or component has been inspected by an independent service center. I got misfire detected on cylinder 3 on 12/17/2025. I replace the sparks plug and it ran fine till 1/10/2026 when all of a sudden I can see the temperature gauge climbing. I stop driving the car that day on 1/10/2026. I check the coolant overflow reservoir on 1/11/2026 and found it strange that it was almost empty. I decide to take it to the mechanic on 1/12/2026 because I didn't see leaks anywhere and that was when they found the head gasket has failed and was slowly dripping coolant into the cylinder.

Head gasket failed after car was fully serviced at authorized Honda dealer.It is a common issue with the 1.5t Honda engine.

Blown Head Gasket, Coolant (possibly oil) leaking into combustion chamber. Confirmed by Honda of Kenner after getting Diagnostic. Car suddenly shook and temperature of car rose, misfires occurred shortly after with a flashing check engine light

My 2018 Honda experienced a catastrophic engine failure (blown head gasket) at only 30,012 miles. A head gasket is not a wear item and should not fail at such low mileage. I previously reported related symptoms during dealer service visits in July 2024 and August 2025, including signs consistent with cooling or engine performance issues, prior to the complete failure. The vehicle has been properly maintained, has not been abused or modified, and shows no signs of neglect. Honda has denied goodwill assistance solely due to vehicle age, despite the extremely low mileage and premature nature of the failure. This appears to be a durability defect resulting in premature engine failure well below expected service life.
