I am filing this complaint regarding my 2019 Honda Accord equipped with the 1.5L turbocharged engine. The vehicle currently has approximately 190,000 miles. My vehicle has developed a serious engine/drivability problem accompanied by multiple warning lights. The warning lights that have appeared include the Check Engine light, VSA/Traction Control warning, Brake warning, Steering warning, Adaptive Cruise Control (ACC) warning, and Road Departure warning. The diagnostic trouble codes found on the vehicle are: P0300 – Random/Multiple Cylinder Misfire P0302 – Cylinder #2 Misfire P0303 – Cylinder #3 Misfire P219A – Air-Fuel Ratio Variation P0420 – Catalyst System Efficiency Below Threshold I took the vehicle to a Honda dealership for diagnosis. After inspecting the vehicle, the dealership told me that I need a turbocharger. I have never previously replaced the turbocharger on this vehicle. I am concerned that a major turbocharger/engine-related failure on a vehicle equipped with the 1.5L turbo engine, combined with multiple cylinder misfires and an air-fuel ratio variation, could create a significant safety hazard. My concern is not simply the cost of repairing the vehicle. I am concerned about what could happen if the engine suddenly loses power, hesitates, misfires severely, or fails to accelerate while I am driving in traffic or attempting to merge onto a highway. The multiple warning lights are also concerning. When the problem occurs, the vehicle displays warnings involving several systems, including traction control, braking, steering, ACC, and Road Departure. This creates concern that safety and driver-assistance features may be disabled or affected at the same time as the engine problem. The vehicle has approximately 190,000 miles, but I believe mileage alone should not dismiss a potentially recurring safety-related defect, particularly when the vehicle is experiencing multiple engine-related diagnostic codes and the dealership has diagnosed a turbocharg

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.

I was driving on the highway in Michigan, the speed limit is 70 mph. All of a sudden, I noticed that my car acceleration was not working. It ended up my engine misfired and in doing so, I could not go more than 20 mph on the actual highway!!! it was absolutely terrifying, even when I put on my emergency lights, I had to find a place to safely pull aside. I still had to pull out in front of someone to try to get off the exit, so pulling out in front of someone at 20 mph on the highway was petrifying. Once, I finally was able to pull into a safe place. I immediately called my insurance company and Honda about the misfiring of my engine. My car was then towed to a Honda dealership, where technicians diagnosed a blown head gasket caused by coolant leaking into a cylinder. The only warning light was the “check engine” flashing light when I was unable to drive more than 20 mph. My vehicle went limp. The repair required replacement of the head gasket at significant personal expense About $6k +.

I am reporting a premature and dangerous failure of the engine head gasket on my 2019 Honda Accord Sport (1.5L Turbo engine, 68,220 miles). While driving, the vehicle suddenly lost power due to severe engine misfires. Simultaneously, the dashboard experienced a total cascade of safety system failures, illuminating warning lights for the Check Engine Light, Electric Parking Brake, Traction Control (VSA), Road Departure Mitigation, and Adaptive Cruise Control. The vehicle currently in the authorized honda dealer where technicians officially diagnosed a blown head gasket leaking coolant into Cylinder 3. This is a widespread, well-documented manufacturing defect with Honda's 1.5L Turbo engines. I request that the NHTSA launch a formal safety investigation into American Honda for these premature head gasket failures to force a mandatory safety recall.

Complaint Regarding Ongoing Issues After Turbocharger Repair – 2019 Honda Accord I am submitting a complaint regarding ongoing issues with my 2019 Honda Accord after a turbocharger-related repair. The initial diagnostic code associated with the vehicle was P2563 (Turbocharger Boost Control Position Sensor Circuit Range/Performance). After the turbocharger/wastegate repair, my vehicle began displaying multiple system warnings, including: * Emissions System Problem * ACC (Adaptive Cruise Control) warning * Collision Mitigation System warning * Lane Departure/Lane Keeping Assist warning * Electric Power Steering warning * Stability/traction control warnings * TPMS (Tire Pressure Monitoring System) warning After the repair, the vehicle began jerking and experiencing a loss of power. Multiple warning lights appeared. While the warning lights temporarily cleared after a couple of vehicle restarts, they later returned and continue to reoccur. I subsequently took the vehicle to Honda, where I was informed that a sensor required recalibration. Despite having the sensor recalibrated, the issues have continued, and the warning lights continue to return. I am requesting that Honda investigate whether the repair, wiring, sensors, modules, calibration, or the turbocharger system itself may have contributed to these ongoing problems. I have also noticed that many Honda Accord owners are reporting similar turbocharger-related issues and multiple warning lights appearing. This appears to be a very common issue among affected vehicles, and I believe it warrants further investigation to determine if there is a larger underlying problem affecting these vehicles. I am requesting that Honda review this matter, document these concerns, and provide a proper resolution. Thank you for your attention to this matter.

While driving my 2019 Honda Accord Hybrid at highway speed, the engine suddenly suffered catastrophic failure. The engine block ruptured, leaving a large visible hole with internal engine components exposed. Oil was expelled into the engine bay and ignited/burned briefly. This occurred without prior warning at highway speed and created a sudden loss-of-propulsion hazard. The vehicle has approximately 48,500 miles and has had regular on-time maintenance via Honda dealership. No warnings or other symptoms were active prior to engine rupture event. Fire dept & NYS police arrived on scene prior to being towed. The vehicle is currently preserved at Sussex Honda dealer for inspection and awaiting diagnosis.

I was told the best thing to do was report it here. Our son was driving his 2019 Honda Accord and suddenly everything on his dashboard lit up. Was told it is a blown head gasket. We were also told that the shop has had over 81 Accords in with the same issue. They said Honda is trying to sweep it under the rug rather making a recall. We were told this is what they see: The head gasket material between cylinders is very tiny, any minor disturbance will cause coolant to leak into the cylinder. Usually failures are happening between cylinders 2&3 where the material is the thinnest. 2) Honda is really trying to get a lot of power out of this small engine with the inclusion of the turbocharger. Higher octane fuels are needed to prevent premature detonation / knock, especially with forced induction (turbo charger). You can still run the car using 87 octane, but the chances of problems like a blown head gasket happening increase. 3) The head bolts that keep the engine head to the engine block are not strong enough. These bolts are torque to yield at around 50 ft lbs (if that). There have been instances where these bolts don't have enough clamping force to withstand the pre-detonation. This force causes the head to jump and the bolts to stretch. The heat from the combustion in the cylinder is no longer contained, which warps and damages the head gasket over time, leading to its failure. It was suggested to use ARP studs which we were told are a higher quality than the OEM Honda head bolts and have a stronger clamping force. Our son ended up stranded 3 states away with this issue that we then learn is VERY common yet there are no recalls.

In May 2022, the air conditioning condenser on my 2019 Honda Accord Hybrid was replaced due to AC failure. In April 2023, shortly after purchasing the vehicle following a lease buyout, I returned with the same AC issue and was told the condenser may have been defective and it was replaced again. I then took the vehicle to another authorized Honda dealership, where I was told the condenser may not have been replaced previously, and it was replaced again. Dye was added to the AC system at South Motors Honda to identify a leak. Despite this, Largo Honda later charged me again to add dye, stating they could not access the prior dealership’s diagnostic records, even though both are Honda-authorized dealerships. After continued AC failure, two authorized Honda dealerships have now diagnosed the issue as a leaking air conditioning evaporator and documented the failure with video evidence. Loss of air conditioning impacts driver safety by impairing windshield defogging and creating unsafe cabin temperatures, particularly in hot weather. This represents a premature failure of a non-wear component. This issue has persisted since 2022. The manufacturer declined repair assistance despite repeated repairs and dealer-confirmed diagnostics.

This has happened out of the blue and randomly more than once recently. loss of power/no acceleration. once it had no acceleration when taking off from a stopped position, and then again it lost acceleration while driving at a speed of around 50MPH the car would no longer accelerate, had to pull off to the side of the road and turned the car off and let it sit for a few minutes and then restarted the car and it resumed to function normally. there are no codes in the system, no warning lights, this has happened 4 different times now. Honda says they cant do anything if they cant make it repeat the problem when they diagnosis it and if the system doesnt have any active codes in it.

On May 13, 2025, I took my car to the Honda dealership, because all of the lights on the dashboard came on. I was told that the clips on my turbocharger needed to be replaced, and so Honda fixed that $120 (diagnostic fee) $209.99 to fix the issue. I was traveling so they kept the car for a week. I received the car back, and about 2 weeks later, 06/03, the same thing occurred, I was told that the engine air filter needed to be changed, and it caused the lights to go off $32.84. The next day 06/06, the lights went off again. I took my car back to the Honda dealership and they had the car from 06/09 - 09/04. Today they have reached out to say “It took a while to recreate the issue because they are ‘masking each other.’ There is a leak in the head gasket, and the turbocharger is going out.” It would be cheaper to buy a used engine and used turbocharger than to have it rebuilt.” I have spoken with other Honda owners, who have a 2018-2022 Honda accord, that have experience the same issue.
