2019 Honda Accord problems

ENGINE

Coolant is leaking into my cylinders due to the head gasket design flaw. Engine now needs to be replaced and it’s over $6,000. My car has about 150k miles. About 18 months ago it started misfiring, even while on the highway multiple times with my children. Codes came back saying i needed to replace ignition coils and spark plugs. Did that over and over and over. Turns out this is an on going issue with this specific year and model. I bought this car with 4 miles on it. I’m left without a car. This need to be recalled. I have read over 4,000 stories of others having the same issue.

UNKNOWN OR OTHER

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.

ENGINE

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.

ELECTRICAL SYSTEM

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.

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 +.

My car began to not turn on. Took it to the dealership, was told it was the turbocharge being loose. They saw coolant leaking. Paid for the fix. Few days later, car lost power and entered lint mode. Took it back and with simple camera work they check the gasket was leaking. Told that since the turbo before wasn’t working as intended, the gasket became thin. Repairs are above 6k, had no warning lights. Seems this is a common issue.

I received a warning light indicating my car was reaching maximum internal temperature. I immediately shut off the car, then took it to the Honda service center the next morning. They did an inspection and determined there is a leak in my head gasket at cylinder 3. There were no warnings prior to the time of failure. I had recently had my coolant flushed as part of general maintenance and I never missed an oil change. Vehicle inspections at the Honda Service Center regularly showed no issues.
