2018 HONDA ACCORD Complaints

2018–2022 Accord models with 1.5L turbocharged engines are experiencing premature head gasket failures. Honda is facing class-action lawsuits regarding these engines, and there are known Technical Service Bulletins (TSBs) for issues like cylinder misfires. Full injectors .

I am reporting a failed remedy for Recall 24-009 (23V-858). Following the fuel pump recall, my 2018 Accord stalled in traffic on March 21. On March 24 upon starting my vehicle all warning lights were illuminated on the dashboard, Millennium Honda admitted the O-ring was misinstalled. This error triggered codes P0172/P0176 less than twenty-four hours later. The dealer is forcing me to pay $425 for damage caused by their botched recall repair.

The contact owns a 2018 Honda Accord. The contact stated that the engine overheated while parked, with the message "Engine Temperature too High - Do not Drive - Allow Engine to Cool Down" was displayed. The vehicle was taken to two independent mechanics, where the spark plugs and battery were replaced, however, the failure persisted. The vehicle was then taken to a local dealer, where it was diagnosed with head gasket failure. The manufacturer was notified of the failure. The approximate failure mileage was 96,500.

I started driving this vehicle and all of a sudden it started slowing down, and would not go up to speed. I had it fixed, the car started skipping, making a jerking movement while driving. I made an appointment with Tameron Honda of Birmingham on 3/26/26. As soon as I pulled up to Honda dealership the engine light was on. The company was trying to bill me 6100 dollars for fixing the car. I do not have that amount on hand and I need my car. I had to drive my car away from the dealership while it was in idle mode state into traffic the car moved so slowly that I could have wrecked. The dealership did not do their due diligence by going off of the vin number and making sure that the customer is safe with their brand. I was told that they did a full inspection at the dealership. I have been scared to drive this vehicle since the issue keeps happening.

Failing head gasket - cars stalls. Coolant reservoir goes empty. Check engine light go on.

Head gasket blown, apparently this has been a known problem with Honda, which they are refusing to repair, noting mine did not come from a specific factory. [XXX] 2018 ACCORD 1.5 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As soon as I got to work and put it in park I got a message on the dashboard saying “Engine Temperature Too Hot. Do Not Drive. Allow Engine To Cool”. No other warning signs were shown before this. I looked up on google what maybe it meant and to my findings it mentioned gasket and all I noticed recent complaints and claims filed with 2018 Honda accords for a known issue with these Honda accord sport 2018 models for blows gaskets.

I owned a 2018 Honda Accord,i got it new from the dealership so im the only owner of this vehicle. my headlights keep building condensations prematurely causing them to fail . I have already replaced multple headlights because of this . also when the bulbs go out honda made it where the bulbs can not be replaced at all. these headlights cost close to $1000 each plus 500 in labor to installed. theres should be a recall for this as its costing me soo much money . I hoping we must hold accountability to its highest level so consumer dont have suffer like this. Thank you so much for reading!

Almost all of the 1.5T engines (L15BE) are having head gasket issue where the gasket slowly fails over time resulting in slow coolant loss and at one point sudden overheating causing block and head warping die to design flaw ( groove in between the cylinders resulting in lack of effective and enough surface area for the head gasket to seal the combustion chambers). It has been confirmed by Honda techs and by average 100k to 140k, all engines are failing and the dealers are raking up $ 6k to 9k charge for each change or even having to need new engines half the time. This process of slow leak results in sudden loss of power at highway speeds or acceleration and causing extreme danger of getting hit and having accidents. Took vehicle to mechanic and confirmed coolant leak inside cylinder 4 and 3.

I own a 2018 Honda Accord equipped with Collision Mitigation Braking System (CMBS). The vehicle has experienced multiple instances of false collision warnings and phantom braking. The issue occasionally occurs when approaching overhead interstate signs. In most cases, the system flashes brake warnings briefly and then clears. However, on one occasion during rainy conditions a few years ago, the vehicle unexpectedly applied the brakes at highway speed with no obstacle present. The vehicle has undergone multiple camera calibrations (this may have also included the radar), but the problem persists. This creates a serious safety hazard, particularly at highway speeds where sudden braking could result in a rear-end collision. The issue appears to be related to false object detection by the ADAS system, potentially involving radar or sensor misinterpretation.
