ENGINE
My Honda vehicle experienced a blown head gasket at approximately 123,000 miles, despite being properly maintained according to the manufacturer’s service schedule. This is a known and recurring issue in this engine type, which has been the subject of numerous consumer complaints and a pending class action lawsuit alleging a design defect that causes premature head gasket failure. The engine failed without warning signs such as overheating or coolant loss prior to the incident. I contacted Honda’s customer service and the Goodwill Program, but they declined to assist, stating the vehicle was out of warranty. A head gasket should not fail at this mileage, and this appears to be a widespread safety and reliability issue that may affect other vehicles with the same engine design. I am requesting that NHTSA investigate this pattern of premature head gasket failure in Honda vehicles and take appropriate action to hold Honda accountable for the defect and ensure consumer safety.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I own a 2018 Honda Accord that was subject to a fuel pump recall. The dealership replaced the fuel pump in July 2025 as part of the recall. Shortly after the replacement, all dashboard warning lights illuminated. I took the vehicle in for diagnostic inspection and was informed that the fuel injector and head gasket had failed. The estimated cost of repairs is $5369.69. I believe these failures may be related to the fuel system recall or indicate a broader defect in the vehicle’s engine or fuel components. I am deeply concerned about the safety and reliability of the vehicle, especially since these issues arose immediately after the recall repair. I am currently unable to afford the repair, and I fear the vehicle may pose a risk to myself and others on the road. This situation has caused me significant stress and anxiety. The unexpected financial burden has disrupted my personal and professional life, and I feel unsafe driving a vehicle that may have underlying defects. I am frustrated that a recall repair may have led to even more severe mechanical issues, and I am left without clear support or resolution. I had no choice but to pay for the repairs out of pocket, despite the financial strain. I am seeking guidance on how this cost might be recovered—whether through manufacturer assistance, warranty extension, or further recall action. I respectfully request that NHTSA investigate whether this issue is connected to the existing recall or represents a wider safety defect affecting other vehicles of the same make and model.

I had submitted last year a complaint about my vehicles head gasket being blown. Had to take a loan out to replace it and the turbo . Now a year later the head gasket failed again which shouldn’t have since I’ve been on top of maintenance. My vehicle is a 2018 Honda accord 1.5T .

ENGINE, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
My vehicle is losing power while traveling on the road. All of the system lights are flashing and the gas mileage is ridiculous. It sputters uncontrollably and just stalls out and drops speed really quick. I’m really concerned for my well being. I’ve spent so much money trying to fix these issues and I don’t think it’s fair to me or any other Honda owner to have to be held responsible for something that is clearly a manufacturing issue. Although there was not a crash during this incident, it’s very dangerous and I’m terrified to drive my car but I have no other transportation right now.

3 weeks after having this vehicle, the car started running hot and experiencing all types of jerking problems. I started to do my research on why suddenly the car was running hot, jerking, and other things. I noticed a thread line expressing the EXACT same issues that I was experiencing which were from bad head gaskets. I took my vehicle to the dealership to have this issue checked and verify. I also had an independent mechanic shop evaluate the vehicle as well. Both results were the same. This is a design flaw on the manufacture behalf and I reached out to the Honda Corporate only to be denied assistance with fixing the known issue because it was “out of the date” range for their goodwill claim. This vehicle will run hot and you will have to pull over on the side of the road to allow engine to cool in order for it to operate.

While accelerating car jerks at times. At time car will go in limp mode I’ll have to safely try to get to side of road turn car off. Restart and continue driving. I’ve changed spark plugs, coil packs, turbo, fuel injectors, fuel pump and battery. I continue to put money into my car and nothing helps.

Lost coolant and engine over heated. Inspected by shop and determined that the coolant is leaking into the engine due to head gasket issue. This could cause extreme engineer overheating and cause fire in engine. based on available information from other owners of the accord 1.5T 2018, this is common issue.

The contact owns a 2018 Honda Accord. The contact stated while driving approximately 50-55 MPH, the vehicle was jerking before shutting off. The accelerator pedal was depressed, but the vehicle failed to respond. The contact was able to move over safely. The vehicle was restarted and continued to drive. The ABS, steering, battery, engine, and Lane Departure warning lights were flashing. The vehicle was taken to the local dealer for NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline). The vehicle was repaired, but the failure reoccurred. The vehicle was taken to another local dealer, Shelor Motor Mile (270 Jarrett Dr SE, Christiansburg, VA 24073), who confirmed that the fuel pump had not been serviced. The manufacturer was not contacted. The failure mileage was approximately 101,000. The VIN was not available.

My 2018 Honda Accord Sport has experienced repeated engine and turbocharger problems related to a likely head gasket failure. For nearly two years, I had to replace the spark plugs every six months without ever getting a check-engine light. When I brought the vehicle to Hardin Honda in Anaheim, the dealer ran a test and said the head gasket was fine at that time. However, the issues continued, and eventually, the head gasket and turbocharger both failed. I can't spent about $4,000 in repairs, and I lost significant time without my vehicle, which affected my ability to work. Additional Details: Honda replaced my fuel pump twice. The first failure caused my engine to go into limp mode on the freeway, which was extremely dangerous and also damaged the turbocharger. Honda replaced the engine computer (ECU) only six months after I purchased the car. When I contacted Honda corporate, they admitted to being aware of this issue but said they would only offer reimbursement if a recall was issued in the future. Safety Concern: The sudden loss of power at highway speeds is a serious safety hazard. This issue appears to be widespread among owners of the 1.5L turbo engines, and many drivers are reporting similar head gasket and turbocharger failures. Requested Action: I am requesting a formal investigation into the 1.5L turbo engine design and related head gasket and turbocharger failures in 2018 Honda Accords. These problems pose a clear safety risk and result in high out-of-pocket repair costs for owners.

POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: WARNING
The issue first appeared during my initial test drive before purchase in 2019. The salesman stated it was a low-battery issue from the car sitting on the lot. Since then, the same problem has recurred multiple times. The vehicle displays multiple warning lights — “Electric Powertrain Fault,” Check Engine, EPS, and VSA — with reduced power, jerky acceleration, and temporary loss of throttle response. This poses a safety risk when merging or crossing intersections. Vehicle: 2018 Honda Accord Sport 1.5T, approximately 52,000 miles. Diagnostic codes retrieved include U0401-68 (ECM/Electric Powertrain Communication Failure), U0416-68 (VSA/EPS System Malfunction), and P0302 (Cylinder #2 Misfire). These faults have occurred despite replacement of spark plugs, ignition coils, and fuel injectors (all OEM Honda parts). Dealerships have not been able to permanently correct the issue. The problem appears related to the ECM or communication network between the powertrain and stability systems. The sudden loss of power and unpredictable throttle response during normal driving creates a serious safety hazard.

Head gasket problem. Coolant leaking into cylinder #2, head gasket needs replacing. The car is currently at a Honda dealership & they inspected/ confirmed that this was the issue. They expressed this was a common issue with this car. The first signs of issues happened while driving uphill on the freeway, the car started to “jump” when trying to accelerate. A couple of minutes later, the car would not accelerate while driving & the check engine light turned on. The second time, this happened much quicker. In a span of a couple of seconds, the car “jumped” while driving on the freeway again, and slowed down and would not accelerate, but various lights on the dash turned on this time. This is obviously very dangerous as a car suddenly decelerating while driving can cause the driver and others on the road to crash. There were no warning lights on prior to the first incident.

I have a 2018 Honda accord 1.5t I have always done oil changes and maintenance accordingly. My car went into limp mode over the summer. I brought it to my dealership who said the head gasket was bad and it was going to cost over 5,000$ to fix. This is a known problem on these cars as I have gathered information all over the internet. Honda refuses to do the right thing and have a recall. I do not have the money to replace the head gasket at the hefty dealership level. I have been waiting over 3 months in an attempt of a DIY replacement. The company I have been ordering with has had many issues and I am still without a vehicle. The vehicle only has 138,000 miles
