2018 HONDA ACCORD Complaints

I was slowing down to pull into a parking spot at my office and suddenly the car accelerated, jumped the concrete barrier and crashed into the brick wall. The car continued to actively crash into the wall, so I put it in reverse and it accelerated backward with such force that it crashed into the rear of the car on the other side of the parking lot and then spun around 180 degrees and crashed into the side of that same car. My car was terrifyingly out of control. There was a woman in another car who had just parked and luckily she remained in her car because if she'd gotten out my car could have hit her. I don't know if this is related, but I regularly used the brake hold function and pressed the button to turn it off as I was parking. My perception is that the car suddenly accelerated when I depressed the brake hold button to turn it off. I have the parking lot security camera footage that clearly shows I was braking when the car suddenly accelerated and went out of control. I had 3 hard collisions and the airbag didn't deploy. Luckily I only had some neck and back pain and wasn't seriously injured. My car and the other car were totaled. I'm incredibly disappointed that Honda didn't call me back in time to be able to inspect the car. The insurance company pressured me to settle and turn over title. I'm very angry that the insurance company says I'm at fault because I need to stay in control of my vehicle at all times, but how could I have done that when the car suddenly went out of control? Now I'm going to have to pay higher insurance rates for something that I couldn't control.

The contact owns a 2018 Honda Accord. The contact stated that while depressing the accelerator pedal from a complete stop, the vehicle lunged forward. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors and spark plugs had failed and needed to be replaced. The contact stated that the failure recurred approximately 5 years later while accelerating from a complete stop at a stoplight, and the vehicle failed to accelerate at the intended speed. The vehicle was towed to the dealer, where it was diagnosed that the transmission sensor had failed. The vehicle was repaired; however, the failure recurred while attempting to leave a parking lot. The contact stated that the failure remained persistent and was recurring more frequently. The vehicle was taken to another dealer, Carson Honda(1435 E 223rd St, Carson, CA 90745), who performed a dual-clutch transmission check, but no failure was found. Additionally, the dealer diagnosed that there was excessive misfiring on cylinder #3 due to a head gasket leak. The dealer determined that the head gasket kit, the spark plugs, and the fuel injectors needed to be replaced, and an oil change needed to be performed. The vehicle was not repaired. The contact stated that the vehicle had become inoperable. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was unknown.

I am submitting this complaint to report a potential safety-related defect in the 1.5L turbocharged engine used in the 2018 Honda Accord. My vehicle experienced a sudden and severe head gasket failure that appears to be related to a known design flaw affecting a significant number of Honda 1.5T engines. Many owners are reporting the same. Vehicle Information: Owner: [XXX] VIN: [XXX] Mileage at failure: 127,000 miles Location: [XXX] Phone: [XXX] or [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Several system warnings. Dealership diagnostic "bad fuel injectors" Vehicle has 62,735 miles.

The problem I am having with my vehicle Honda accord 2018 is with the head gasket. I was on the highway and as I was driving suddenly all the signs came on the display and gave a warning that my vehicle is overheating and it came down to 20mph while I was on the highway. This was very risky to me and the other vehicle around me.

Car has lost power or gone into "limp mode" while driving on multiple occasions. Car was never listed under the fuel pump recall but had all associated symptoms & problems. Had to have fuel pumps replaced in December 2023 due to car not starting because of faulty fuel pumps. Car has been properly maintenced since purchased brand new in February 2018. currently around 121,000 miles. Car overheated this past summer, Coolant seems to be leaking somewhere as just filled with coolant month ago and needed to refill with about quarter to refill to correct amount. Oil also seems to be having slow leakage problem somewhere within the engine as there is excessive oil on drip pan. Had all 4 spark plugs changed in March of 2025. Car has been going into limp mode and looses power for few seconds to minutes sometimes, almost causing multiple accidents while driving on highways. Pull over to shut off and give few minutes to restart and able to resume driving No warnings before this occurs. Randomly all dashboard lights light up 2 weeks ago and put car into limp mode, was driving on highway at high rate of speed (65mph) safety was compromised several times while this occurs. Engine seems create knocking sounds to known due to oil dilution problem. Cold weather seems to affect issues to onset more often. Also been having stalled or rough start ups in colder weather or when engine is not warmed up. Researching these issues seems to be that 2018 Honda Accords had known head gasket failure. This should become a class action lawsuit and also a recall

After having fuel pump replaced by recall at random times dashboard will light up with all system lights, car will go into limp mode and loose power for a few seconds and then I am able to resume driving. Extremely scary as there is no warning. This has happened both on the freeway at high rates of speed and on neighborhood roadways. Safety has been compromised several times and Honda dealer is not able to reproduce the issue, retrieve any warning codes or offer any assistance. This has randomly been occurring for several months. When not having this exact issue car runs with no other issues.

Engine knock caused by oil dilution which is known manufacturing issues with my model of car.

I was driving in my car cut off in the middle of the highway. I was able to coast to side of the road. I took my car to the Honda accord dealership after that and was told it was my head gasket. After that repair, my car cut off once again. I took it back to Honda and was told that I now needed to replace the turbo charger which I’m unable to pay for after paying several thousands of dollar for the head gasket.

The problem I am having with my vehicle Honda accord 2018 is with the head gasket. I was on the highway and as I was driving suddenly all the signs came on the display and gave a warning that my vehicle is overheating and it came down to 20mph while I was on the highway. This was very risky to me and the other vehicle around me. Then when I took it to the dealership to diagnose they said it is a head gasket failure. The repairs they have recommended are very expensive and after researching this problem it shows this is a very common problem Honda vehicles are having. This is a manufacture problem which they should have a recall on hence with such expensive repair and I only have 93K miles on my vehicle. I always thought Hondas were the best vehicle going long term and as I am first time owner and this being my first vehical brand new I am very disappointed with the problem I have been facing with my vehicle.
