2018 HONDA ACCORD Complaints

Upon commuting to work, the car failed to accelerate causing the car to almost suddenly stop while driving; at the same time of the failure warning lights and beeping occurred. No warnings prior to failure. By God’s grace, I was not yet on the expressway and avoided what would have been a horrible accident jeopardizing not only my life but the lives of anyone that would have been behind me. The gasket failed (cylinder #3) and is available for inspection upon request. It was a significant safety issue as the failure occurred without warning causing the car to stop no warning. Yes, the dealer has confirmed the failure and I was quoted a $5800 repair cost in spite of a owning a lifetime power train warranty. No, the vehicle or component has not been inspected by the manufacturer, police, or insurance. I did place a call to American Honda and we were given a case #15822812 (but this case has since been closed without action.) No warnings occurred before the failure. (Beeping and messages occurred at the time of failure.) Had the failure occurred at a high rate of speed, on an expressway, loss of life could have occurred and no one would know what caused the accident since cars are usually towed away and declared “totaled.” Fortunately, I was on a road of 35mph but in just a few more minutes would have been at a speed of 65mph. There is a further safety concern that the dealer admits that there is a known problem with the OEM component but plans to continue to replace with the same product. Note: this car has a superior care record and only 110,000 miles which means the failure is likely to occur again with the same parts. Internet searches are confirming this is a known product failure with no recall.

The contact owns a 2018 Honda Accord. The contact stated that upon starting the vehicle, various warning lights were illuminated. The contact stated that the Lane Departure, Lane Keep Assist, ACC, and Blind Spot Detection warning lights remained illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and the contact was informed that the malfunction or warning lights were a result of the camera being faulty and that the camera needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 105,000.

The paint on our 2018 Honda Accord is fading and the clear coat is no longer on the car on the areas of the hood, trunk and roof at this point. The roof is having issues with the paint peeling and rusting in all four corners. We have reached out to our Honda dealership and did not receive any help with this issue. This car is great shape inside and out except the paint issue. The paint should last longer and it should not be rusting. We do not want the rust to continue as it will soon damage our car.

Check Engine Lights Turned On and Turned Off all advance features on car because of a faulty fuel injector which is the stock fuel injectors that were designed by Honda

Car has 60,675 miles with a blown head gasket. Prior to blown head gasket vehicle was brought to Honda in April 2025 for overheating, rough start and leaking coolant and was told fuel pump had a recall so it was changed, Honda did the recall repairs, performed oil change and checked everything else and released the car in working order but a week later after adding 175 miles more to the car it started overheating and had a rough start, the car was immediately brought back to Honda and they said it was a blown head gasket, the car was driven home that same day and left in the driveway undriven until September 3rd 2025 when it was towed to a different Honda dealership where it was confirmed to be blown head gasket and the cost is estimated at $6800 to repair. The car has had all recall issues addressed as well as all service and oil changes done to the vehicle, the car is driven for leisure and never in an unsafe or harmful way that could damage a head gasket.

While trying to accelerate the car loses power. This has happened many times. The Honda dealership has said the system is on back order and they will call me when it’s available. It’s been months. The “jerks”a few times then the check engine light comes on then the car loses power. The dashboard lights are brake system, emission system, electric power steering, hill assist and ACC system problem.

Head gasket between cylinders 2 and 3 blown, despite regular maintenance being completed by Honda dealerships. This issue has caused vehicle to go into "limp mode" while on the highway leading to safety concerns. This problem has been confirmed by not only a Honda dealer repair shop but also an independent repair shop and owners. There were not warning prior to the failure. Per the dealership, this is not something that could be caught during regular maintenance and inspections.
