2018 HONDA ACCORD Complaints

This vehicle was built terrible. It had a blown head gasket at 86,000 miles. The head was warped. My valve guides and seals were compromised and leaking into the combustion chamber. I need a full head resurfacing job with new gaskets all around. New injectors and new valve cover gasket and everything around. This car has a design flaw and needs to be recalled for mediocre heads life. It almost caused me to get crashed from the back from a semi truck because the car decided to lose complete power while on the road. The cars recalls have been addressed but this whole issue with the faulty heads needs to be addressed. My vehicle is in the shop now and I will have to pay a little over $4,000 now. It's a hazard on the road when you get near to 90,000 miles.

Scanned for codes. Found P0303, P0299, and P2243 stored. Found coolant entering cylinder 3. Found excessive play in the waste gate rod and found A/F sensor is not responding. Needs head gasket. Vehicle starts up and runs rough. All alerts on alerts on dash on cust states check engine light on. Honda sensing alerts on.

Took in my vehicle to Rock Honda in Fontana at 125,000 miles for a second fuel pump recall. Two years ago my car stalled on me as I was driving on the freeway, it immediately decelerated from 65 MPH to 40 MPH, this happened before I had the first fuel pump recall fixed. Did the second fuel pump recall, and days later my car again began to decelerate from 50 MPH to 5 MPH. Brought it into the dealer and they told me my head gasket was blown.

About a week ago my all my dash lights came on dash. Doing some research I found there was a safety recall on my vehicle that I did not know about. I scheduled an appointment with Honda to get it replaced, they informed me that the fuel injectors needed to replaced and were causing misfires. They claim this is not directly correlated to the recall but I believe that it is

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the vehicle stalled and shuddered. The contact stated that several unknown warning lights were intermittently illuminated. The failure had occurred on several occasions. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the spark plugs, and air filters needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 35,000.

The collision mitigation braking system is engaging while I’m driving with no obstructions in front of me. The car slows down completely while I’m on the highway almost coming to a complete stop. This has happened numerous times since Dec 2024. I took it into Honda and they did absolutely nothing besides charge me over $500 for diagnostic fees and told me to get an oem battery and bring it back to be inspected again.

Subject: Safety Complaint – Premature Head Gasket Failure in 2018 Honda Accord Hybrid (VIN: [XXX] ) Dear NHTSA Representative, I am submitting this letter as a formal complaint regarding a serious and premature mechanical failure in my 2018 Honda Accord Hybrid (VIN: [XXX] ). At approximately 96,000 miles, the head gasket failed, resulting in major engine problems and potentially unsafe vehicle performance. I am the original owner of this vehicle and have maintained it consistently in line with Honda’s recommended service intervals. The engine has never been overheated or misused, yet the head gasket has failed much earlier than expected for a modern vehicle, especially a hybrid model. After researching online, I have found multiple reports of similar issues involving 2018 Honda Accord models experiencing premature head gasket failure, many of them under or near 100,000 miles. I am concerned that this may point to a widespread defect that could compromise the reliability and safety of these vehicles. A sudden head gasket failure can cause the engine to overheat, lose power, or even stall — all of which present potential risks to the driver and passengers, especially at highway speeds. I respectfully request that the NHTSA investigate this issue further to determine whether a safety-related defect exists and if a recall or manufacturer action should be issued. Thank you for your attention to this matter. Please feel free to contact me if any additional information is needed to support the investigation. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Warning lights come all across the dash stating to see the dealer. I have taken it to the dealership and the issue is the fuel injector that causes the warning lights to go off and on at random. I still have a warranty of my car and was told the warranty does not cover that part. This is happening to a lot of honda accords but there is no recall for it. There is a safety issue for driving because they stay on and then go off and come back on again. This is unfortunate and unacceptable from Honda as a whole. I bought the car in May 2024 and the warning lights came on a week later and have been ever since off and on.

My vehicle is experiencing engine hesitation and it's getting worse every day I drive my car. This is a known side effect of the Honda Safety Recall notice I originally received in February of 2024. I received initial notification of a safety recall for my Honda vehicle in February of 2024 and it stated the safety issues of a possible faulty fuel pump modular. The letter expressed that they have no available parts but were working on getting them. I then received a 2nd letter regarding the fuel pump in May of 2024 and that parts were limited so they were focusing on customers who were experiencing side effect/safety issues with their car. I then received a 3rd letter in November of 2024 stating parts were ready and I just needed to contact my local Honda dealership to have my fuel pump modular replaced free of charge. I have called my dealership on at least two different occasions and have also taken my car in to Honda since then for general maintenance (oil change) and I keep being told they do not have the parts. The last time I spoke with them, I keep getting told that they do not have the parts. I am also always told they will probably call me in a couple weeks when they have the part but I never received that phone call from them. I can never seem to get a straight answer from them and am always told another excuse as to why my car and my family's safety is not important enough for them. I've even been told some of those replacement fuel pumps are needed for their newer cars.
