2018 HONDA ACCORD Complaints

Blown head gasket. This appears to be a widespread issue amongst all 10th gen honda accords due to a poorly designed engine by Honda.

Rough downshifting and upshifting in low gears. Will slam into gears 2-3 often seems as though at slower speeds and cause driver and passengers to lurch forward. Will cause very rough acceleration at times and causes a danger in traffic given the speed becomes unpredictable. Transmission does not know what gear to be in. The ATF type 2.0 fluid change following dealer procedure after complaint has done nothing to change this lurching. This is putting me and other drivers at risk because I cannot control my speed when transmission is slamming in between gears. No warning lamps, undetected by cars TCU.

I keep having issues where my car thinks I’m changing lanes and alerts me, when I’m not, and auto-corrects my steering which has led me to actually veer into another lane and fighting the car essentially while driving. I turn the feature off and somehow it just keeps happening. Same with the sensor that auto brakes - there won’t be anything that the car should be braking for and I’ll get the flashing BRAKE text come up on dash and beeping before it completely brakes on its own. These issues and features have been more worrisome and scary than helpful. There are multiple instances

At 144000 miles all vehicle lights came on and vehicle engine would shake and vibrate. Computer said misfire on cylinder three. Changed spark plugs and coil. Problem still persisted. Mechanic recommended replacing fuel injectors so i did. After injectors were replaced all the lights came back on and the car runs worse. I believe its a blown head gasket now and the mechanic is testing the head this week.

Driving in a construction zone. Two lane highway and my car immediately went into limp mode. Left me and my children stranded on the side of the road while semis and cars driving 65 mph went past very close to us. Honda knows these accords have head gasket issues and it is unsafe to be driving them.

I own a 2018 Honda Accord EX-L with a 1.5L turbocharged engine. The vehicle began overheating while idling and at low speeds, cooling down when driving at higher speeds. I brought the vehicle to a Honda dealership where a pressure test confirmed internal coolant loss with no external leaks found. The dealership diagnosed a head gasket failure and recommended replacement at a cost of $8,941. The component that failed is the head gasket on the 1.5L turbocharged engine, allowing coolant to leak internally into the cylinder. My safety was put at risk as the vehicle overheated while in traffic during normal driving conditions, creating a risk of engine failure, loss of power, and potential fire. The problem was confirmed by a certified Honda dealership via cooling system pressure test. A goodwill request has been submitted to American Honda on my behalf. Warning lights appeared on the dashboard twice indicating to turn the vehicle off immediately due to overheating. Symptoms first appeared in April 2026. I am aware of NHTSA TSB MC-10234626-0001 and an active class action lawsuit Bissell v. American Honda Motor Co. Case No. 3:24-cv-02286 addressing this exact defect on this exact engine.

Subject: Formal Complaint – Unresolved Safety Issues Following Recall Service (2018 Honda Accord) I am submitting a formal complaint regarding ongoing and unresolved safety issues with my 2018 Honda Accord, which began during the time frame of a fuel pump recall and have not been properly resolved despite multiple attempts with Honda service departments. Approximately two years ago, my vehicle was subject to a fuel pump recall. During the extended wait period for the replacement part, my vehicle began displaying multiple warning messages and experiencing performance issues. These issues included reduced acceleration and erratic driving behavior. Once the recall repair was completed, I was informed that an additional repair—a battery sensor replacement—was necessary, which cost approximately $800 out of pocket. Despite completing both the recall repair and the recommended sensor replacement, my vehicle has not operated properly since that time. Currently, the vehicle intermittently displays multiple system warnings, including but not limited to: - Emission system problem - Brake system and brake hold system problems - Electric power steering problem (reduced steering assist) - Vehicle stability and traction control warnings - Adaptive cruise control system problem - Collision mitigation braking system problem - Road departure mitigation system problem In addition, the vehicle frequently enters a reduced power or “limp mode,” making it difficult to accelerate safely, particularly at lower speeds. Restarting the vehicle temporarily resolves the issue, but the warnings and performance problems return shortly after. I have brought this vehicle to Honda service departments on multiple occasions. The vehicle was held for extended periods without resolution, and I ultimately had to retrieve it without a clear diagnosis or repair plan. I also contacted American Honda for assistance and did not receive meaningful support.

Infotainment center continually freezes. When it does, backup camera does not work. I have tried software updates but it has gotten worse. It is also very slow to reboot so again, no backup camera during that time.

Apparently, my car has a leaking head gasket. It was confirmed by the Honda Dealership. While driving it will go in limp mode and will no longer accelerate. I have to pull off to the side of the road, turn the car off, and back on just to get to where I'm going. It is causing my car to stutter really bad and we're constantly having to put coolant in it. This is a safety issue and will cost about $7000 to get fixed. The most recent time it did it, I was at a stop sign and starting to go to turn and my car just would no longer accelerate.

I just submitted a complaint but wanted to add that after my car lost all power on a 45mph road and went into limp mode it then was towed to the closest shop. I do have a warranty but when I called Honda they said it wasn't covered The shop I took it to charged me 4100 dollars for a blown head gasket which from researching it looks like this is happening to all 2018 Honda accords This is low mileage and unacceptable , turns out after I called and told Honda they refused to pay because I had already had the shop look for the problem So I had to pay 4100 for an issue Honda clearly knows about This is unfair and Honda needs to fix this issue
