2018 HONDA ACCORD Complaints

On the morning of July 26, 2025, while returning home from a grocery shopping trip, my vehicle experienced a sudden and severe loss of power while traveling on an interstate highway with a posted speed limit of 65 mph. Without warning, the car ceased to accelerate and began to decelerate rapidly. I immediately activated my hazard lights and attempted to locate a safe area to stop. Vehicles traveling behind and alongside me were forced to brake abruptly to avoid a collision. Fortunately, no accident occurred, though the situation clearly presented a significant risk of one. After pulling onto the shoulder, I turned the vehicle off and restarted it. It initially appeared to operate normally, allowing me to resume driving. However, within a few minutes, the loss-of-power incident occurred again. I managed to pull over a second time, restart the vehicle, and continue the approximately 10-minute drive home without further incident. Upon taking the car to my mechanic, I was informed that coolant was present in one of the cylinders, indicating a failed head gasket. The mechanic advised that I bring the vehicle to an authorized Honda dealership for repair. The Honda service department performed diagnostics and confirmed the head gasket failure. The repair cost was $3,758, which I paid in full. Subsequent research revealed that this appears to be a widespread issue affecting certain Honda models manufactured between 2018 and 2022. I discovered numerous consumer complaints online and learned that a class action lawsuit has been filed regarding this exact defect. Based on my understanding, head gasket failures are uncommon—particularly in vehicles with relatively low mileage. My vehicle has approximately 83,000 miles on it. While I am dissatisfied with the substantial financial burden of this repair, my greater concern lies with the serious safety risk posed by the sudden loss of power at highway speeds. I respectfully request that this matter be reviewed.

On August 7, 2025, the automatic braking system alerted with the sign break and then proceeded to stop the car when there was no object or vehicle in front of me. This would have been extremely dangerous. If there was someone behind me this is not the first time this has occurred it has happened several times.

Fuel pump recall. Put in an order with Honda dealer January 2024 for the pump. On February 2025 asked if they submitted the order back in January 2024? They said it was. Now it's August 2025 (20 months since) and waiting. NHTSA says if they failed to fix in a timely manner to make a report online. Is 20 months long enough? Driving with a safety recall. Second making a complaint with the 10 speed auto transmission 2nd to 3rd hard shift and 4th to 3rd hard shift. Putting stress on other components can break mounts, the transmission, axles, ect. could also launch the car into the car in front of you, in heavy (slow bumper to bumper) traffic. Wasted my own money and time draining and filling 5 quarts of honda 2.0 transmission fluid. (Also replaced the trans filter behind the warmer housing) Did not fix the issue. Contacted American Honda and they said It's out of warranty and I need to pay for diagnostic and repairs. (I just bought the car in 2023 at 45k miles. Previous owner must of felt it and should of did something while under warranty.) Honda know this issue from the beginning and hiding the issue to save money. Check the Accord forums online. It's most of us if not all the 18-20 10 speed models. Vehicle is 2018 Accord 2.0 10 speed 50k miles. Plus the normal Phantom braking and lane departure which will automatically steer you off the road, so you have to fight the steering wheel.

I own a 2018 Honda Accord EX-L (VIN#: [XXX]). Shortly after a service visit to a Honda dealer for unrelated maintenance (in Sep. 2024 with an estimated 50,000 miles), the dashboard began showing ‘Supplemental Restraint System Problem – See Dealer’. A dealer quoted $400+ to diagnose and replace what appears to be a common passenger airbag indicator sensor failure, a known issue reported by many 2018 Accord owners. I believe Honda should issue a recall due to the safety risk. I’m filing this as a VOQ complaint for ODI’s review and authorize NHTSA to share my identifying info with Honda if needed. Supporting Documentation and numerous examples of complaints from hundreds of Honda Accord owners relating to this problem: - Numerous drivers of 2018 Honda Accords have reported the identical warning (“Supplemental Restraint System Problem – See Dealer”) along with fault code B002013, intermittent dashboard behavior, and inability of dealers to resolve it consistently. - Honda’s 2024 Campaign 24-050 identifies the seat weight sensor as directly causing SRS warnings and passenger airbag indicator failure - demonstrating this component is known to fail and trigger airbag system alert behavior, even if not yet applied to 2018 model year. - Independent coverage confirms the risk and design defect in seat sensors causing unintended SRS failures, underscoring the safety risk and Honda’s formal acknowledgment of the issue in later models. - Multiple complaints about post-service warning lights that match this scenario (electrical system category), and public news coverage stating Honda is recalling vehicles due to faulty passenger seat sensors that may cause airbag or SRS failures. - 37 official complaints for the 2018 Accord, with no repair by dealer and failure left unresolved. One report (May 12, 2025) describes this exact issue saying the dashboard message randomly popped up and a "dealer wanted $250 diagnostic and $4,000 to repair. - My service quote attached. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION AC

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the vehicle stalled, and several unknown warning lights illuminated. The contact attempted to drive the vehicle off the road, and the engine seized. The contact stated that the failure had occurred while driving on a busy highway. While attempting to restart the vehicle, the vehicle failed to start. The contact stated that due to the failure, the vehicle was almost involved in a crash. The contact stated that drivers were shouting and were very aggressive. The contact was concerned for his safety and considered calling the Police for assistance. The two nearby drivers attempted to jumpstart the vehicle and assisted with pushing the vehicle off the road. The tow truck arrived on the scene and attempted to jumpstart the vehicle, but the vehicle failed to start. The tow truck driver determined that the vehicle failed to start due to a possible fuel pump failure. The vehicle was towed to the dealer. The contact referenced an unknown recall; however, the VIN was not under recall. The contact stated that the vehicle was towed to an independent mechanic and was diagnosed with fuel pump failure. The contact was advised to tow the vehicle to the dealer. The vehicle was towed to the dealer and was repaired; however, the contact was not informed of the cause of the failure until after the repair was completed. The contact requested the diagnostic information and was informed that the failure was fuel pump failure. In addition, the contact stated that an unknown gasket needed to be replaced and there was evidence of a coolant leak. The contact stated that because of the failure the vehicle was towed three times. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 88,630.

While driving my 2018 Honda Accord, the engine began running roughly and the check engine lights and multiple warning lights came on. The vehicle was taken to a Honda dealership for diagnosis. The service department informed me that coolant was leaking into the engine, causing damage to the head gasket and cylinders 2 and 3. They confirmed this issue and recommended either an expensive head gasket/cylinder repair or a full engine replacement. Prior to this failure, I occasionally noticed mild engine hesitation, but no specific warning messages about low coolant or overheating appeared until the check engine light activated. The dealership stated this is not an uncommon issue with this engine. Upon further research, I discovered many other 2018 Accord owners with the same 1.5L turbocharged engine have reported coolant intrusion, cylinder damage, and head gasket failures — often affecting cylinders 2 and 3 specifically. This appears to be a design or manufacturing defect in the engine. This type of failure poses a safety risk due to potential engine misfires, power loss, or stalling while driving. The problem was confirmed by a licensed Honda service center, and I believe this issue should be investigated further for potential recall or manufacturer accountability.
