2018 HONDA ACCORD Complaints

The Acoustic Vehicle Alert System (AVAS) stopped emitting sound for no apparent reason. On June 2nd, I took it to Honda service center, they said the speaker behind the front bumper needed to be replaced. I paid $699.56, only to discover that the AVAS still didn't work. I took it back, they said the accoustic unit needed to be replaced. I paid $707.57. On June 18th, they called me to pick up the car; I asked if the sound was working, they said the sound was there but it wasn't as audible as in other comparable cars. When I drove the car, I found a parking lot and drove below to 25 miles, even when the car was put in EV mode, I personally could not hear any noticeable sound even with the window open. I had contacted American Honda, and reported the issue, especially that the service centers didn't seem to know how to fix the issue. I requested from American Honda that they dispatch an egineer or provide the Honda service centers with directiond how to fix. Nothing happened. I'm not convinced that the AVAS was fixed. The design is faulty and many cars risk to be grounded because of that. The worse part was that the Honda service centers are not able to fix the issue. I just wasted $1,407.13 (plus the Uber rides) for nothing. Also, I don't understand why they held the car from June 2 until June 18th, and when I asked about the status, no meaningful update was given. This issue is likely to occur again with thounsands of hybrid cars.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? I purchased my 2018 Honda Accord in 2024, and in 2025, I experienced significant issues with the vehicle. During my visits to both Honda of Southaven and Honda of Tupelo, they indicated that the head gasket might be the problem, which is a known issue with this model. I believe the malfunction is related to this component, and I can confirm that it is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The issues with my vehicle have directly endangered my safety and the safety of my children. While driving, the car started jerking unexpectedly and then cut off entirely on the highway, which could have resulted in a severe accident. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I have visited Honda of Southaven and Honda of Tupelo over three times reporting these problems. Both dealerships acknowledged the issue, with one dealership stating it was likely the head gasket, which they mentioned seeing frequently with Honda vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? I have not had an inspection by the manufacturer or police. However, I have had my vehicle inspected by two authorized Honda dealerships, where they diagnosed the problem. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, before the failure, there were multiple warning lights on the dashboard, which indicated that something was wrong with the vehicle. These symptoms began appearing shortly after I purchased the car in 2024, and they escalated over time leading up to my visits to the dealerships in 2025.

Had in tank fuel pump replaced as recall stated. After 1 year went bad again. Honda refused to cover the repair. My car stalled on the interstate in traffic running around 50 to 60 mph.

The Body Control Module of my 2018 Accord has failed. At 70,000 miles on my vehicle the door locks began to be unresponsive. At 100,000 Miles all door locks were unresponsive to the door control and fob control. The only way to secure my vehicle is to manually lock all doors and use the key within my fob to unlock the drivers door and then manually unlock all other doors. Ed Martin Honda in Indianapolis inspected the vehicle and determined the the Body Control Module would need to be replaced to make the Door locks work. There were known issues with the Body Control Module as there was an active recall for the software of the system. I completed the recalls software update at the time it was issued but this seems to be a continued problem.

On June 24th, 2026, I received a warning for "Supplemental Restraint System Problem". The airbag Dash indicator illuminated on the dash. The issue is intermittent and the warning has appeared on five separate occasions since. The message had went away when the vehicle has been turned off and has not appear every time the car is running. It does appear mid-travel on occasion. The issue is consistent with the passenger airbag sensor failure description recall that is associated with other VIN Numbers for the 2028 Accord but my VIN is not listed in the recall.

The contact owns a 2018 Honda Accord. The contact stated that while the vehicle was parked, the brakes intermittently failed to engage while the brake pedal was depressed. Several unknown warning lights were illuminated. The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 104,000.

I purchased the car in November 2025 from Carvana. By December, all the dashboard lights came on and no one can locate the problem. The car still runs but not to its optimum performance.

1. Head gasket and turbo system 2. I was driving on the highway at 55mph and the front end of the car started to shake so I pulled over to inspect the car as best I could. 3. The Honda dealer did a diagnostic for my AC $450 and $200 for the hazard lights. I was told my AC needed to be charged and then the prices to replace my head gasket, turbo and coolant flush for a total of 10k. 4. All of the warning light came on in the vehicle as I was driving and my AC started to blow warm air June 29, 2026.

My Engine is overheating, cannot drive the car at all. There is Coolant loss and leaking into the cylinder. It is Rough running and misfires: no matter when I start the Honda whether a fold start or not it is chunky and wants to give out. There is Loss of power which makes my car feel sluggish and is very dangerous as I’m driving myself, children and family on the freeways of St. Louis. I have never had any other issue and maintained the maintenance on the car. Honda dealership wants 6k to start fixing it. Could be more after they get into it.

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.
