2019 Honda Accord: check engine light

Filed Oct 13, 2026 · Electrical, Engine · TX

Air conditioning failure: The A/C was blowing warm air on the first day of ownership. • Cooling system failure: The vehicle subsequently experienced overheating issues and left me stranded. • Coolant loss and radiator leak: All Star Honda identified a leaking radiator and found the cooling system out of coolant. • Failed thermostat: A failed thermostat was identified during the diagnostic and repair process. • Stop-leak substance found in the cooling system: Stop-leak material was observed in the cooling system. I have concerns about why it was present and not disclosed initially • Water pump and cooling-system repairs: Repairs included work on the thermostat and water pump, followed by radiator replacement and a coolant flush. • Continued overheating concerns: Despite repairs, I continued experiencing overheating alerts. • Engine performance problems: The vehicle experienced a loss of power, with a reported inability to maintain speeds above approximately 60 mph during one incident. • Check-engine warning: A prior repair-order history documented a blinking malfunction indicator light during a driving incident. • Diagnostic trouble codes: Codes P2601 and P272D were subsequently reported. • Potential head-gasket concerns: The possibility of a head-gasket problem has been raised during the ongoing dispute. Honda has referenced a multi-model cylinder-head-gasket warranty extension, but I have not received approval for coverage on my vehicle. • Warranty denial: Honda corporate has declined to approve the requested warranty coverage. Despite the repeated problems, diagnostic visits, and repair attempts, I am still dealing with the consequences of purchasing a vehicle that has not provided the reliable transportation I paid for. I have spent time and money trying to get answers, and I have been left facing the financial burden of a vehicle that I cannot confidently depend on. I am sharing this timeline because consumers deserve trans

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

Vehicle started sputtering, then all the engine lights came on. The car felt like it did not want to drive. Took it to the dealer for diagnosis. Dealer reported that the head gasket needed to be replaced. He stated that this is a known issue but that Honda has not issued a recall. The car only has $100,000 miles. Dealer said to call American Honda to see if they would give any "good will" money. They declined.

My engine started to jerk while going over 2,000 RPM. I took my car into Firestone and they claimed they fixed the issue. Unclogging the fuel, nail in the tire and other issues that were unrelated. I drove for about a week and the issue came back with my check engine light coming on and my car not being able to accelerate past 2,000 rpm. I took the car back to Firestone and they replaced the spark plugs and claimed that the car was "good as new" once again about a week later I found myself on the side of the road with a check engine light. Thankfully I was able to make it home, after doing that I finally took my car to the dealership. After the diagnosis was done, the repair costed around 8,000 $ to replace. The issue was a head gasket replacement and a fuel injector as needing to be replaced because of the leakage of coolant into the cylinder. Due to some research, it turns out that their is a lawsuit against Honda for this exact issue with the same Make and Model car I have. I asked the Manager of Honda to file a Goodwill request and they declined it. No reason why, just declined it. Now I'm currently in the process of getting my car fixed at another shop getting my car fixed for half the price.

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 own a 2019 Honda Accord Sport 1.5T that has an ongoing, unresolved engine/powertrain problem causing severe loss of acceleration, jerking, and a flashing check-engine light. The exact component causing the failure is UNKNOWN. The vehicle is available for inspection upon request. I initially took the vehicle to an authorized Honda dealership and paid over $300 for diagnosis. Honda diagnosed the fuel injectors. I then paid approximately $800 at an independent shop to replace the fuel injectors, but the same problem continued. The vehicle was later evaluated by other repair providers. I was advised that the problem could involve the turbocharger wastegate actuator and, separately, the spark plugs and ignition coil packs. I replaced the spark plugs and coil packs, but the problem continued. Another shop later tightened/adjusted the wastegate actuator, but the vehicle continues experiencing the same issue. During a failure while driving, the vehicle lost acceleration, jerked, and the check-engine light flashed. The engine would run/turn over, but the vehicle would not accelerate or move normally when the accelerator was pressed. This left me unable to reliably maintain speed with traffic. My [XXX] daughter was with me when the vehicle became disabled, leaving us stranded on the side of the road in the summer heat until someone could pick us up. The sudden loss of acceleration created a risk of collision and left us exposed to roadside traffic and high temperatures. The vehicle has been inspected by an authorized Honda dealer and multiple independent repair providers. Despite multiple diagnoses and repairs, the dangerous loss-of-power condition continues. I am reporting this because the unpredictable loss of acceleration while driving presents a safety risk to my family and other motorists.

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 federal safety agency launch a formal safety investigation into American Honda for these premature head gasket failures to force a mandatory safety recall.

Hill start assist problem vehicle may roll upon brake release, collision mitigation braking system problem, electric power steering system problem. Steering assist reduced, collision mitigation braking system problem. Road departure mitigation system problem. My car when I first start it in the morning idles very hard and then settles. I have taken it to honda and tried to get it covered under the tsb but the lights went off and they claim they could not pull the codes. This has happen several times and my car is under 150,000 miles. This is a safety hazard in traffic when the car decides it wants to stall.
