2018 Honda Accord Fuel system Problems

SUPPLEMENTAL DATA FOR ACTIVE ODI CASE #XXX. P1: SYSTEMIC SAFETY RECALL FALSIFICATION (NHTSA 23V-858) This submission supplements active ODI Case #XXX against Honda of Manhasset (Facility #XXX). On XXX, the facility certified Fuel Pump Safety Recall 23V-858 as fully completed to claim warranty credits. Vehicle dashcam recordings irrefutably prove the technician never opened the hood, never disconnected the 12V battery (mandatory safety step to release fuel pressure), and never stood in front of the car. When confronted on XXX with video evidence, advisor [XXX] manually altered the invoice to "Not Performed", falsely blaming a system error/lack of stock, despite parts records proving the recall kit arrived XXX. System admin then issued a corrective invoice "Reprint #1" stating "RECALL NOT PERFORM. PART NOT IN STOCK", dynamic-reopening the VIN nationally to evade corporate detection. This constitutes severe corporate fraud. P2: COMPRESSED ADAS SOFTWARE TOLERANCES AND PROCEDURAL OMISSION The secondary fraud involves an unneeded quote of $1,237.19 and illegal $233.55 diagnostic fee under false pretense of a "bent radar bracket". Independent engineering audit disproved hardware failure, establishing true 0.00° baseline. Technical root cause of DTC P2583-76 was the recall update, migrating the car from the factory 2018 software layout—which possessed a permissive vertical threshold up to ±3.0°—directly to hyper-strict Program ID: 36802-TVA-A190, restricting the window to an unyielding 0.0°±0.1°. Due to suspension settling over 259,258 km, the radar had a natural deviation of -2.25°, which A190 flagged, disabling ACC. On XXX, the Shop Foreman confessed technicians willfully skip physical radar re-centering protocols because they "take too much time". After manual adjustment back to 0.00°, a 19km road test dynamically cleared DTC [XXX] per Honda Bulletin 21-068. Subpoena dealer records for ID A190.

The car hesitates upon acceleration and when it “misses” enough it will flash the engine on the dashboard, and not allow any further acceleration, going into “limp mode”. All the safety controls error on the message center and dashboard warnings all come on, even though it’s only the acceleration/transmission that’s affected. Not sure if it’s fuel injectors or a computer issue, but it’s absolutely dangerous upon entering a highway and hoping to not have system failures, that result in limp mode. I’ve been carrying a 10 mm socket for disconnecting the battery and rebooting the system, when needed. It only helps for a short while.

Reporting fraudulent safety recall compliance & hazardous repair by Honda of Manhasset (Invoice #317524). 1. Recall 23V-858 (Fuel Pump): Dealership registered recall as completed & Service Manager verbally insisted it was done. However, my vehicle's continuous dashcam footage proves fuel pump replacement was NEVER performed. Faced with video evidence, the advisor admitted work wasn't done because the part was out of stock, claiming a "billing error." Invoice reprint says "RECALL NOT PERFORMED, PART NOT IN STOCK" yet they initially processed it, leaving an immediate engine stall risk. 2. Software Campaign & Radar Failure (Service Bulletin 21-068): Dealership performed mandatory Honda Sensing update for Millimeter Wave Radar, wiping old calibration parameters. Per Bulletin 21-068 (Pg 3), the repair is NOT complete until the radar is re-calibrated & the warning light disappears. Instead of performing the radar aiming, the technician left safety systems locked with DTC P2583-76. I authorized a $215 diagnostic fee, but despite having the scanner connected during the update, the technician failed to follow Honda's official troubleshooting protocol to resolve the code and finish the calibration, returning the vehicle with disabled emergency braking features. 3. False Physical Diagnosis: Staff verbally claimed the radar bracket was "bent" to blame a prior impact. Challenged for physical proof, they admitted performing NO physical inspection, stating they "assumed" it was bent solely because the scanner showed P2583-76. This is a blatant lie to cover up their failure to follow factory troubleshooting workflow for this specific DTC, which dictates aiming the radar, not fabricating physical damage to justify leaving the safety repair incomplete.

In May of 2024, We got a recall letter for an inoperable fuel pump from Honda Automobile Division, & we did not get a replacement. They were short on supply, & those who experienced symptoms as engine light and may have rough engine starts were the priorities. We didn’t get a follow up after 60 days when we received the letter. Now my 2018 Accord has an engine light on, and the car starts up roughly.

Incident

Jul 11, 2026

While driving on a bridge at under 20 mph, the vehicle's head gasket failed, causing the engine to overheat and coolant to leak from within the engine. The vehicle threw diagnostic trouble code P2601 and immediately entered "limp mode," severely cutting engine power and vehicle speed. Because this happened on a bridge with no shoulder to safely pull over, the sudden loss of power created a serious safety hazard — the vehicle could not maintain a safe speed or keep pace with surrounding traffic, increasing the risk of being struck by other vehicles. The vehicle was taken to a Tampa Honda (11000 N Florida Ave), where the failure was confirmed to be a blown head gasket that allowed coolant to leak into the engine cylinders. The head gasket and related components were replaced at a cost of approximately $5,000 to restore the vehicle to safe operating condition. The failed component is no longer available for inspection in its failed state, as replacement was required to make the vehicle drivable. No dealer, manufacturer representative, police officer, or insurance adjuster has inspected the vehicle; only at Tampa Honda facility that performed the repair diagnosed and confirmed the head gasket failure. Prior to this incident, no warning lamps or symptoms were noted — the P2601 code and limp mode activation occurred simultaneously with the sudden overheating and coolant loss, with no advance warning. This failure is consistent with a widely reported defect pattern among Honda vehicles with similar engines, where the head gasket fails prematurely and allows coolant to enter the cylinders. Honda has not issued a recall or acknowledged a manufacturing defect despite numerous consumer reports describing the same failure mode.

I purchased my 2018 Honda Accord Sport from CarMax on January 16, 2026, and I have had several serious problems with the vehicle since purchasing it. Every warning light on the dashboard has come on, my radar system will not stay calibrated, and I have been told that my fuel injectors need to be replaced. In addition, the relay module was already broken when I received the vehicle, which causes the interior lights in my car not to work properly. These issues have caused serious concerns about my safety and the safety of others because I cannot depend on the vehicle’s safety systems or know when another component may fail. The vehicle and affected components are available for inspection upon request. I have attempted to get these problems addressed, but I have not been able to get a satisfactory resolution. The issues have been identified/diagnosed, and I am seeking further inspection to determine the full extent of the problems. I have not had the vehicle inspected by the police or an insurance representative, but I am trying to get the manufacturer/dealer involved so these issues can be properly documented and addressed. I am especially concerned because I have only had this vehicle since January 16, 2026, and I have already put a significant amount of money into it while still owing a substantial amount on the loan. I was also informed that the vehicle could potentially be considered a total loss within the next couple of months. I do not believe it is reasonable for me to be left responsible for a vehicle that I recently purchased from CarMax and that has developed or revealed so many serious problems. I am requesting assistance in determining whether these issues can be properly repaired, whether the vehicle is safe and reliable to drive, and what options are available to me for a resolution given the amount of money I have already invested and the remaining balance on my vehicle loan.

In September 2025, all dashboard lights came on while driving down the road. I immediately pulled over and turned the car off. When turning the car back on, all lights remained on and I drove to the nearest repair shop, where at this time it was beginning to run hot. I was told at this point that the head gasket had blown and this would need to be replaced. I replaced the head gasket for $4100.00. After that, in October 2025, I had to replace the fuel injectors and coil packs. In February 2026, driving down the road, the car was not running hot but all lights came on the dash again and it went into limp mode. The car had to be towed to a repair shop where it was stated that coil packs needed to be changed again. In August 2026, the turbo had to be replaced, resulting in an additional $2500.00

At approximately 44,000 miles, multiple warning lights illuminated on the dashboard of my 2018 Honda Accord (1.5L turbocharged engine), including brake system, electric power steering, and driver-assistance/collision-mitigation warnings, accompanied by a rough start and an engine misfire. I took the vehicle to an authorized Honda dealer, which performed a diagnostic scan and a borescope inspection. The dealer confirmed engine coolant leaking internally into cylinder 3, a confirmed cylinder 3 misfire (code P0303), and a low coolant reservoir, and advised that the vehicle was not safe to drive. The diagnostic scan also returned fault codes across multiple safety systems, including ABS/VSA stability control, electric power steering, the electric brake booster (low-voltage power circuit fault), and the driver-assistance/collision-mitigation system. This is a head gasket failure allowing coolant to enter the cylinders — a failure mode widely reported on this engine — and it occurred at low mileage, creating a risk of engine misfire, stalling, and loss of power. No crash, fire, or injury has occurred. The dealer's repair order documenting these findings is available on request. I have reported this to the Honda corporate, and they are not responding and stalling the delivery or any update on the case. It has been 3 weeks, and it is causing prolonged inconvience and safety issue to me and my family

My Accord reported multiple warnings at engine start up (check engine light, warnings about cruise control, etc.), and the engine ran rougher than normal. I immediately drove to a Honda dealer for service. The Honda dealer, Checkered Flag Honda of Norfolk, Virginia, diagnosed a blown head gasket in cylinder 2, which allowed all coolant to drain into the engine. They also indicated that fuel injectors and spark plugs were compromised and required replacement. The vehicle has approximately 75,000 miles, has received regular maintenance, and was operated in normal driving conditions.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? I purchased my 2018 Honda Accord in 2024, and in 2025, I experienced significant issues with the vehicle. During my visits to both Honda of Southaven and Honda of Tupelo, they indicated that the head gasket might be the problem, which is a known issue with this model. I believe the malfunction is related to this component, and I can confirm that it is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The issues with my vehicle have directly endangered my safety and the safety of my children. While driving, the car started jerking unexpectedly and then cut off entirely on the highway, which could have resulted in a severe accident. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I have visited Honda of Southaven and Honda of Tupelo over three times reporting these problems. Both dealerships acknowledged the issue, with one dealership stating it was likely the head gasket, which they mentioned seeing frequently with Honda vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? I have not had an inspection by the manufacturer or police. However, I have had my vehicle inspected by two authorized Honda dealerships, where they diagnosed the problem. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, before the failure, there were multiple warning lights on the dashboard, which indicated that something was wrong with the vehicle. These symptoms began appearing shortly after I purchased the car in 2024, and they escalated over time leading up to my visits to the dealerships in 2025.

I own a 2018 Honda Accord LX 1.5T. The vehicle has developed an intermittent hard-start condition after sitting overnight. The engine cranks for approximately 5–6 seconds before starting and runs very rough for the first 2–5 seconds before smoothing out. Warm restarts are normal. While driving, the vehicle hesitates and stumbles during acceleration, is slow to build RPM, and fuel economy has noticeably decreased. During one hard acceleration event, the vehicle lost power and the check engine light flashed. I also observed that if I turn the ignition on and allow the fuel pump to prime for several seconds before starting the engine, the vehicle starts noticeably quicker than if I start it immediately. This makes me concerned that the fuel system may not be maintaining proper fuel pressure after the vehicle sits. Because of the hard starting, hesitation, intermittent loss of power during acceleration, and the improvement after allowing the fuel pump to prime, I am submitting this complaint for investigation because these symptoms could create a safety risk when entering traffic or accelerating.

A loss of power while driving on the freeway created a dangerous situation and nearly caused an accident. The issue was diagnosed by the Honda dealer as a misfire of the 3rd cylinder due to a head gasket failure and a fuel injector issue. No other symptoms were detected as this appeared suddenly at the worst possible time.

At 157000 miles I am being forced to replace my fuel injectors and a blown head gasket on my 2018 Honda Accord. As I am sure you are aware, this is an ongoing issue with this model specifically, and yet no recalls have been issued. Please understand that this was a sudden failure as I had no signs there was an engine issue before being forced into limp mode while driving on the freeway. I also had my mother in the car when all of a sudden, my car could not go above 25 mph while in traffic. Thankfully we could pull over safely and were not hurt or killed. All the lights/warning messages on the dash became illuminated before finally settling on an “emissions problem.” All other warning symbols remained lit. My thermostat started to rise dangerously high especially while idling. I cannot stress how terrifying or dangerous this was. After a diagnostic last week at a Honda dealership, I was told I have a cylinder 3 misfire and that after they pressurized the system, they found a coolant leak which is due to the head gasket. I was also told my fuel injectors (which were just replaced in Sept. 2025) are already in need of replacement as well, but that I would only be charged parts for this repair as it would be included with the labor of having to tear down the engine. Despite this, I was still provided an estimate with the full cost of the fuel injectors as well at nearly $1600. My grand total for these repairs came to $6895. I was told at most it would be $6300 – not that that is much of a discount on an issue that should have been recalled. Again, this is a known design flaw and NOT a result of my neglect.
