While my vehicle was in transit, it experienced a sudden and severe loss of engine power. Simultaneously, multiple malfunction indicator lights (MILs) illuminated on the dashboard, and my vehicle abruptly engaged "limp mode." This drastic restriction of speed and maneuverability while in active traffic created an immediate and severe safety hazard, which nearly resulted in a catastrophic collision. Following the incident, a formal complaint was initiated with Honda customer relations. My own independent research clearly indicates that premature head gasket failure is a well-documented, systemic defect within these specific vehicle models; therefore, a constructive resolution was anticipated. While the initial intake communication appeared promising, the subsequent follow-up was highly unprofessional. The Honda representative who returned my call was dismissive of the safety risks involved, lacked basic professional courtesy, and explicitly stated that the manufacturer would offer no financial assistance or mechanical remediation for this known defect due to a lack of service records. The failure of this component represents both a significant mechanical defect and a severe threat to driver and public safety. This report is being filed to formally document the hazardous nature of this failure in transit, as well as the manufacturer's refusal to address or take accountability for an ongoing, documented issue.

Vehicle caused a SEVERE drivability condition while at highway speeds by sputtering, losing power and auxiliary driver's systems becoming degraded. We were able to drive the vehicle in limp mode to a near service station. They ran diagnostics and determined that there were multiple secondary events affecting the ADAS system. They also checked the battery and determined it was marginally good. We managed to drive the vehicle in degraded mode to our home and we changed the battery the following day. Upon doing so, all affected systems became available again and the vehicle's driveability profile was restored. This behavior is incredibly unsettling and UNSAFE. A vehicle that is so sensitive to electrical fluctuations should have BETTER warning systems that would prevent, or at least advise the driver, that an unsafe condition will occur unless the battery is promptly replaced. This behavior could easily cause an accident if the driver is unprepared to react to the vehicle sudden and unpredictable shutdown of engine power and safety systems. This needs to be investigated and corrective measures need to be promptly proposed to affected vehicle.

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle lost motive power and went into LIMP Mode, and the steering wheel seized. The vehicle was taken to the local dealer, and the failure was initially misdiagnosed. The vehicle was then towed to the dealer a second time, and the dealer discovered that the battery and fuel injectors needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was later diagnosed, and it was determined that a gasket had failed. The vehicle was repaired, but the failure persisted. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 72,281.

Upon recent repairs completed by an Official Honda licensed dealership for the fuel pump due to the related issue of stalling, misfiring, insufficient fuel economy and safety concern. My vehicle has continued to stall, misfire or idle extremely rough. Upon local investigation the error code P0203 and P0303 have populated as the most recent issue. No longer allowing me to drive the vehicle as it remains in limp mode. Previously error codes such as P0304 and P0302 as well as the associated error codes for the Injector Circuits indicating “open” have previously been detected intermittently and now permanently. In previous events within the last 3 months I have been stranded on highways due to the same stalling, misfiring and limp mode issue after I have previously been inspected by a Honda dealership and promised the issues would resolve. Unfortunately driving at respectable highway speeds and even local city limits my safety as well as my child and spouse’ safety have been put at risk due to the sudden deceleration caused by consistent misfires or limp mode effect which can cause me to have a collision with no warning. I have nearly been in 3 accidents due to this persistent issue.

The contact owns a 2019 Honda Accord. The contact stated that while driving at varous speeds the vehicle the had experience acceleration hesitation and the check engine light had illuminated. Later, while driving the engine went into limp mode and over the vehicle speed did not accelerate above 15 MPH. The vehicle was later towed to the local dealer who diagnosed that the fuel injectors were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The manufacturer was notified of the failure and referred the contact to the federal safety agency Hotline. The contact was informed that the VIN was not included in the federal safety agency Campaign Number: ( ). The contact indicated that the vehicle had experienced that same failure listed in the recall. The failure mileage was 135,019

My 17 year old drives this car and has suddenly stalled and gone into limp mode 3 separate times (twice on busy highway) with no warning or codes provided. Most recently the vehicle alerted of overheating. After a couple trips to mechanic it was determined that head gasket is going out. It seems that this is a very common problem with this vehicle and an extreme safety hazard. Especially with young drivers as it sent my daughter into panic and nearly caused accident on initial breakdown.

The vehicle, a 2019 Honda Accord, experienced a catastrophic engine failure (blown head gasket) and entered "Limp Mode" after being operated for approximately 18 months with an unaddressed, high-priority federal safety recall (the federal safety agency 23V‑858). The vehicle currently displays DTCs P0100, P0113, and P023D, which indicate severe air/fuel metering and boost pressure correlation failures. Primary Cause: Consequential Thermal Stress The primary cause is likely thermal degradation of the head gasket resulting from a prolonged "lean-burn" condition. Recall Defect: The recalled fuel pump impeller is known to deform, restricting fuel flow. Lean Condition: A restricted fuel supply causes the engine to run "lean" (too much air, not enough fuel). Lean combustion is significantly hotter than normal combustion. Heat Accumulation: Over 1.5 years of operation with this restricted flow, the engine experienced repeated, excessive thermal cycles that compromised the structural integrity of the head gasket. Limp Mode Trigger: The stored codes (P0100/P0113) show the ECU was struggling to compensate for the erratic fuel/air environment created by the failing pump. Secondary Assessment (The Dealer's Claim): The Service Advisor (Paul) has alleged that aftermarket components and a missing turbo gasket caused the failure. Assessment: While aftermarket parts increase scrutiny, a missing external turbo gasket typically causes an exhaust leak or loss of boost, not an internal head gasket failure. Contradiction: The dealer must provide empirical proof that these parts caused the failure, whereas the federal safety agency recall is a pre-documented, manufacturer-admitted defect known to cause the exact stalling and "limp mode" symptoms the vehicle is currently exhibiting. Conclusion: The most probable cause is manufacturer negligence. By failing to provide a remedy part for 18 months, the manufacturer forced the vehicle to operate under a documented defect that creates the exact high-heat conditions required to cau
