2019 Honda Accord Engine

I have a 2019 Honda Accord sport 1.5T that has a blown head gasket. I took it to the dealer and opened a case with Honda through their good will program, but was recently denied because they claim there was no manufacturer defect after the dealership inspected it. There seems to be a lot of people that are having the same issues with this engine, and there are a couple lawsuits against Honda regarding it. The car was inspected at a Honda dealership and they diagnosed it as a blown head gasket and quoted the repair of $5200. A case was opened with Honda corporate through their Goodwill program, but was recently denied as not a fault of the manufacturer. The car overheated on 10/10/25 while driving, potentially leading to engine damage

My family's 2019 Honda Accord with ~80k miles suddenly had all the warnings lights flashing on the dashboard in early July 2025. The initial diagnostic reader showed a Cylinder 3 misfire. After replacing spark plugs, the warning lights returned after one week; at that time, the ignition coil was replaced but the warning lights returned again after one week of driving. The Honda dealership performed further diagnostics and tests, ultimately reporting that the engine needed fuel injectors replaced AND a head gasket. It is important to mention that when we initially called the dealership's service department to make an appointment, the Service representative that answered the phone immediately recognized this issue, saying that it is a well known issue with Accord 1.5 turbo engines. Honda Corporate has stated that the car is outside of the manufacturer's warranty and that there is no recall. Note that there are class action lawsuits in the US on this matter, as well as lots of online traffic of car owners experiencing this issue with the Honda 1.5T engine. It appears that there is a serious design flaw in the engine.

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (P0300–P030X). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a Technical Service Bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018–2019 Accord models with the 1.5L turbo engine. This should be investigated and addressed as a recall to protect drivers.

Blown head gasket on 1.5T engine. It is a common issue that so many owners of this engine have experienced. It was a safety risk because it happened going at 70mph on the highway, the head gasket blew and it limited the power of the engine. Suddenly, acceleration was no longer possible and the vehicle began limping. I had to drive for several miles at a speed of 35mph (the fastest my car could go no matter how much gas you give it) on the shoulder of the road to take the nearest exit and be somewhere safe. The problem has been confirmed by a certified Honda dealership. It The vehicle has been inspected by the Honda dealership. Symptoms that I have not confirmed to be related to the issue are missing coolant without any leaks. I had to refill the coolant without any visible leaks and there were not any leaks found by independent service center.

Car randomly started misfiring took car to Honda was told the vehicle was low on coolant and needed the head gasket replaced

Vehicle went into limp mode while driving at highway speed Slow down dramatically and after that, it wouldn’t go past 10 mph while driving ended up getting it towed back to my place. The following day had a checked out at a mechanic shop, but they did find was that it had a blown head gasket ended up having to pay more than $7000 to rebuild the engine

Turbo failure on my 2019 and dealer quoted 1900$ to fix. I’ve seen many other owners with this exact problem. My car is at risk of failure

The contact owns a 2019 Honda Accord. The contact stated while driving 20 MPH, the vehicle was hesitating and then lost motive power. The vehicle was taken to the dealer where it was diagnosed that the head gasket was cracked, and there was a cooling leak within the cylinders. The vehicle was repaired. The contact was able to drive the vehicle. The manufacturer was notified of the failure. The failure mileage was 108,000.

I spoke with Josh (Service Manager) on 02/22/2023 after coming back to the dealership after the scar stalled while driving on Interstate 635. Almost getting in an accident and trying to drive the car back to the dealership, the car began bucking once again and wouldn't go pass 40 miles an hour on an interstate where the speed limit reaches 70 MPH. I called and spoke to Mr. Rey, the service advisor an explained I was coming in. I arrived and told him I wanted to speak with the service manager immediately, he informed me to give him a minute. I stated to Josh that this was unacceptable and for me to be a loyal customer to where since I've been in Texas for over two years, my car has been serviced there and I have a complete record to show that. All maintenance has been completed and things that aren't, plans are made with Mr. Rey to complete them at a later time that works for my budget. After talking with him, I was told to wait in the waiting room while he looked a few things. After an hour, Mr Rey, comes and said that Josh had two options. To trade out of my car or pay $1495 to have the head gasket fixed instead of paying $2995.00 before taxes. After going back and speaking with Josh, I explained I shouldn't have to pay that because his guys messed up to where you guys have already had to come out of pocket $1500. If he messed up again, that is your problem not mine so I shouldn't have to pay that. He basically said that we already spent money and not putting more into it but I kept telling him, that it was an issue they caused. You took liability for it already when you paid for the first incident then you come back saying, "oh trade out it"? He stated that was all he could offer, so after I ask Mr Rey to bring my car around and explained to Mr. Rey (Because Josh was becoming disrespectful).

My son was driving and car stalled and wouldn’t accelerate . Engine light came on. He shut the car off and restarted. Thank god it happened in a rural road. No issues after restarting. Two days later engine light came on along with a Christmas tree of everything else. Took it to a friend who put it on his snap-on code reader. He said take it too dealership. Find out it’s a fault head gasket. They want 3700 to fix. The car has 87000 miles on it. I have never seen a head gasket go bad on normal everyday cars. I thought Honda was reliable. I thought wrong.

CAR HAS GONE INTO LIMP MODE TWICE. FIRST TIME WAS WHEN I HAD IT FOR 2 WEEKS. I WAS DRIVING 65MPH AND THE CAR JUST STOPPED IN THE HIGHWAY. I HAD TO GET THE CAR OFF THE ROAD TO KEEP FROM GETTING HIT AND CAUSED SOME UNDERCARRIAGE DAMAGE. THE CAR WAS TOWED. HONDA "FIXED" THE LIMP MODE ISSUE BUT REFUSED TO ACCEPT RESPONSIBILITY FOR ANY OTHER DAMAGE CAUSED BY THE CAR GOING INTO LIMP MODE. LAST MONTH I WAS COMING HOME FROM WORK AT 2:30 AM AND THE CAR WENT INTO LIMP MODE AGAIN. THE CAR WAS TOWED FOR A SECOND TIME TO A DIFFERENT HONDA DEALERSHIP WHERE THEY STATED THERE WAS NO WAY THE FIRST DEALERSHIP FIXED THE CAR. THERE WERE METAL SHAVINGS NOTED THROUGHOUT THE SYSTEM, THE FUEL INJECTOR AND ALL OF THE CYLINDERS HAD TO BE REPLACED. I AM CONCERNED ABOUT THE METAL SHAVING NOTED IN MY OIL AND THROUGHOUT THE SYSTEM CAUSING FURTHER ENGINE DAMAGE AS TIME GOES ON. HONDA HAS ALSO REFUSED TO PAY FOR MY RENTAL CAR DURING THIS PROCESS EVEN THOUGH IT WAS A MANUFACTURING ISSUE. HONDA CUSTOMER SERVICE ON 6/7/19 ALSO STATED THAT IF THE CAR GOES INTO LIMP MODE AGAIN AND I GET HIT, ALL ADDITIONAL DAMAGE CAUSED FROM THE ACCIDENT WILL BE MY RESPONSIBILITY.
