2018 Honda Accord Complaints

ENGINE,FUEL/PROPULSION SYSTEM — Filed 07/22/2026

My Accord reported multiple warnings at engine start up (check engine light, warnings about cruise control, etc.), and the engine ran rougher than normal. I immediately drove to a Honda dealer for service. The Honda dealer, Checkered Flag Honda of Norfolk, Virginia, diagnosed a blown head gasket in cylinder 2, which allowed all coolant to drain into the engine. They also indicated that fuel injectors and spark plugs were compromised and required replacement. The vehicle has approximately 75,000 miles, has received regular maintenance, and was operated in normal driving conditions.

Blown head gasket at ~94k miles. Cost over $7k to replace with a used engine and Honda offered zero reimbursement assistance. This is a major problem on the 10th generation engines.

At approximately 159,000 miles, my vehicle exhibited multiple dashboard warning lights simultaneously including ABS, VSA, EPS, TPMS, brake, ACC, CMBS, and RDM warnings along with engine misfire codes. Borescope inspection confirmed coolant intrusion into cylinder 1. Cylinders 2, 3, and 4 were dry. Diagnosis confirmed head gasket failure consistent with the known design defect in the 1.5L turbocharged i-VTEC engine related to inadequate head bolt clamping force versus boost pressure. This failure is the subject of active class action litigation (Bissell v. American Honda Motor Co., Case 3:24-cv-02286-AJB-MMP). Vehicle requires full head gasket replacement at my own expense estimated at $900+. No recall has been issued despite widespread reports of identical failures across 2018-2022 Honda Accord 1.5T vehicles.

I bought this car used and I've only had it two months and the head gasket has blown. I didn't know the 10th generation had bad gaskets and turbos i found that out after I purchased the car. Literally everyone i know now that had one the gasket or turbo went out. Not only that it was a recall on my fuel pump no one told me about until I added it to my insurance and they told me. Yes Honda dealership fixed it for free now it needs to be a recall on these turbos and head gaskets. It's not fair. I wouldn't recommend Honda to no one now and they say Honda last a lifetime. Thats not true quit making the 10th generation and take it off the market.

What component or system failed or malfunctioned, and is it available for inspection upon request? I own a 2018 Honda Accord with approximately 132,000 miles. Shortly after my vehicle was serviced for the fuel pump recall, multiple warning lights and system failure messages appeared simultaneously. The affected systems include Road Departure Mitigation, Emission System, Adaptive Cruise Control, Auto High Beam, Collision Mitigation Braking System, Electric Power Steering, Vehicle Stability Assist, Tire Pressure Monitoring System, Hill Start Assist, and the Air Bag System. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The failure of multiple safety and driver-assistance systems has created a significant safety risk. My vehicle is currently operating in limp mode, resulting in reduced performance and making it difficult to drive safely in traffic. The loss or malfunction of systems such as collision mitigation braking, power steering, vehicle stability assist, adaptive cruise control, and air bag monitoring increases the risk of an accident and could jeopardize the safety of both vehicle occupants and other motorists. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. I took the vehicle to a Honda dealership for diagnostic testing after the warning lights appeared. The dealer confirmed that multiple systems were reporting faults. I was advised that numerous components would need to be replaced at a substantial cost. Prior to the fuel pump recall service, I had not experienced any of these issues and the vehicle operated normally. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by a Honda dealership for diagnostic purposes. To my knowledge, it has not been inspected by Honda corporate, law enforcement, or insurance representatives. Were there any warning lamps, mes

When going 55 mph car started leaching back and forth aggressively followed by loss of engine power. Car decelerated to a max of 20 mph and would not accelerate past that. This caused the potential of getting rear ended in traffic. When I took it to the mechanic, they told me that my first cylinder was misfiring and that my fuel injector was the issue. A warning light only came on after the car decelerated to a low speed.

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.

FORWARD COLLISION AVOIDANCE — Filed 05/26/2026

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.

AIR BAGS — Filed 06/24/2026

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.
