2018 HONDA ACCORD Complaints

My 2018 Honda Accord Touring with a 1.5L turbocharged engine began experiencing intermittent warning lights and error messages starting around 28,000 miles. I reported these issues to a Honda dealership on some visits however in most cases, the warnings were appearing and disappearing prior to my visit. However the error continued to appeared since then. At approximately 55,000 miles, multiple warning lights and error codes reappeared consistently. I took the vehicle to a Honda dealership for diagnosis and was informed that the issue may involve internal engine damage and that a full engine teardown would be required to determine the cause, at an estimated cost of approximately $2,000, before any actual repair could be identified. Seeking a second opinion, I took the vehicle to a different service location and completed a full tune-up at 63,000 including all standard maintenance expected at that mileage. Less than one week after the tune-up, the same warning lights and error codes returned. I took my car back to the same place where I had the tune-up completed and the same error codes appeared indicating the issue was not related to routine maintenance. I began to research online some common issues with my car, I became aware of a class action lawsuit (Bissell v. American Honda Motor Co., Inc.) describing a known defect in Honda 1.5L turbocharged engines where coolant leaks internally near the cylinder head, causing engine misfires, efficiency warnings, and internal engine damage. The symptoms described in the lawsuit closely match the ongoing issues with my vehicle. The repeated warning lights and potential for engine failure raise safety concerns. The issue has been reproducible and unresolved despite inspection and maintenance.

Head gasket blown at 75500 miles. This appears to be an issue with the 1.5T engine in these cars, as reported several times and at issue in a class action lawsuit Bissell v. Honda.

My 2018 Honda accord had coolant leaking in cylinder 3. Which caused the head gasket to blow. My car stopped on me in the middle of the hwy. I took my car to a shop down here to get fixed he couldn’t get it to run. All dashboard lights are on.

My wife was driving on a highway while taking our grandchildren to day care. The vehicle lost power causing her try ti pull to the side of a main highway. All of the check engine lights went on. We brought the vehicle to Honda and the dealership said they found coolant in the combustion chamber. It needs a head gasket, at a cost of $4800.00. The car has 76,000 miles on it. We understand that there is currently a class action lawsuit for Honda Accords of this year and make. Kindly advise us as to what we can do as this is causing us extreme stress and financial hardship. We need help. Thank you for your assistance. Sincerely, [XXX] and [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting this as a formal and urgent complaint regarding serious safety issues with a vehicle I recently purchased. The trunk opens on its own while I am driving, which creates an immediate safety hazard. In addition, the backup camera is malfunctioning, further increasing the risk when reversing or parking. Shortly after reporting the trunk issue, the radio also stopped working. I have contacted the dealership regarding these concerns, but no corrective action has been taken. Given that this vehicle was recently purchased and involves active safety risks, this lack of response is unacceptable. I am requesting immediate inspection and repair of these issues, as well as written confirmation of how the dealership plans to resolve this matter promptly. Please consider this issue urgent due to the safety risks involved. I look forward to your immediate response.

On Nov 7, 2025, I took my 2018 Honda Accord (VIN: [XXX] ) to "Honda of Gainesville" (Dealer #208034). 1. Recall Negligence: The dealership performed unauthorized repairs on the vehicle's fuel system (alleged fuel injector failure). However, while the vehicle was in their service bay for fuel system work, they failed to perform or even disclose active NHTSA Safety Recall 23V-858 (Fuel Pump), which is open on this specific VIN. The dealership prioritized unauthorized, billable fuel repairs while knowingly releasing the vehicle with a mandatory federal safety defect still present in the fuel system. 2. Safety Coercion: Service Advisor [XXX] used safety fear tactics to coerce the unauthorized work, claiming the vehicle was entering "limp mode" and would become inoperable/dangerous to drive. Independent diagnostic analysis (OBD2) performed after the service revealed ZERO error codes and no history of the claimed failure. The dealership fabricated a safety hazard ("limp mode") to generate revenue while ignoring a real safety hazard (Recall 23V-858). Associated Investigations: A formal complaint regarding the unauthorized repairs has been filed with the Florida Dept. of Agriculture (Case #XXX-XXX).

Emissions and engine light turned on which caused enginue to lose power and stall. Took car to dealership for diagnosis, and two codes related to failed fuel injectors and failed turbocharger. Tech said it is a known failure with this vehicle model, especially with the Honda turbo engine, so much so the warranty was increased from 100,000 miles to 150,000. Unfortunately my car was 15,000 miles over warranty and will be a costly bill. Online research yielded that tech was right, it is a known failure issue with this model but I missed the warranty extension. If this is a known issue by the manufacturer, should this not he a recall issue?

Upwards of a dozen times my Honda Accord will suddenly brake as it believes I am about to have a collision whereas it is typically a shadow. This happens when going under bridges or overpasses, or depending on the glare from the sun. This has happened several times on the highway causing multiple near collisions at high speeds. This is extremely dangerous and requires an adjustment or recall. I have had this part stolen and replaced through a Honda approved repair shop yet the issue persists.

As I was driving myself and child on the interstate 65 mph the vehicle all of a sudden dropped speed and would not accelerate. I drifted the car off the interstate off ramp and pulled into a store parking lot. Luckily, we did not cause an accident or hit anything or anyone. All the lights on car's dashboard blinking some examples are EPS, VSA, Malfunction lamp, Breaking system, check engine light, etc. My car did not show that it was running hot, was not smoking, however would not accelerate. The car had a slight rattle, running bad, shaking slightly; all in all, not working appropriately. No earlier indication that something was wrong just came all of a sudden, no warning at all. Car was brought to Billy Navarre in Lake Charles, LA, where they concluded that head gasket was blown. I had to come out of pocket to fix the head gasket and all of the other problems that it caused. Car milage 84,097, bought brand new in 2018. This is a major safety issue for the public! Multiple people have this same problem. I have documentation on all the work the dealership completed. And I have filed a report to Honda.

I have a 2018 Honda Accord Sport 1.5 The issue started after getting my fuel pump replaced as part of the recall. While driving, all of the dashboard lights came on. Warning messages kept flashing on the dash. This car was driving perfectly fine before the fuel pump was replaced. When the codes are cleared, the car drives perfectly fine. The dashboard lights will periodically turn off but ultimately come back on and as a result, the car goes into limp mode. Coils, sparkplugs, breakers have been switched out and oil levels have been checked. When the car is scanned, the codes are reading a misfire with the coils but, the coils that are allegedly misfiring were JUST replaced. The car jerks while attempting to accelerate, and after a few miles, it goes into limp mode. I have tried every type of repair that has been suggested to me by the mechanic but the issues persist.
