SUBJECT: A REQUEST FOR HONDA CORPORATE INVESTIGATION AND GOODWILL ASSISTANCE - 2021 HONDA ACCORD I am submitting a formal complaint regarding serious and recurring electrical and safety-related problems with my 2021 Honda Accord. 1. Numerous dashboard warning lights and safety-system warnings illuminate simultaneously. 2. The vehicle repeatedly displays messages instructing me to "See Dealer." 3. The power door locks repeatedly click and cycle as though they are attempting to lock or unlock on their own. 4. The stereo, on its own, scrolls through buttons and bluetooth blinking through all the stereo options on its own. 5.An OBD diagnostic code reader is unable to properly communicate with the vehicle and reports "Unable to Connect/Vehicle Not Found." 6. Sudden brake activated without any object being in front of the vehicle. 7. Factory Rims Extensive finish failure The simultaneous occurrence of these problems strongly suggest that this may involve an electrical, communication-network, body control module, wiring, power-supply, or other vehicle system defect rather than ordinary wear and tear. I am particularly concerned because the dashboard warnings involve vehicle systems that may affect braking, steering, stability control, driver-assistance features, and other safety functions. When numerous safety warnings illuminate at the same time, I have no reliable way of knowing which vehicle systems are actually functioning correctly. The repeated activation of the door-lock system is also concerning. The locks should not continuously activate on their own during normal vehicle operation. Combined with the diagnostic communication failure and multiple warning messages, this raises concern regarding a larger electrical or vehicle-network malfunction. Although the vehicle is currently outside the factory warranty period, this type of widespread electrical and safety malfunction should not reasonably occur in a 2021 vehicle as the result of normal use.
My car currently has displayed all lights on panel. Went to auto zone to have codes read, shows powertrain-description is code PO299 suggests turbocharger assembly. Safety is put at risk because all of the safety features are now disabled.

40,000 miles and 5 years after original in service date - failure of 2021 ACCORD 1.5T headgasket system between cylinder s #1-2. Required full head disassembly, removal, rebuild of head, and replacement of head gasket and associated components. $6000 quote from Honda Corporate as I was 55 DAYS outside of warranty. Absolutely ridiculous for a 5 year old car with low miles.

I own a 2021 Honda Accord Hybrid. Shortly after purchasing the vehicle as a used vehicle in 2023, I began experiencing intermittent air conditioning performance. The A/C would gradually lose cooling capacity over time until it was no longer able to cool the cabin effectively. To temporarily restore operation, I added refrigerant approximately twice per year, believing the system had developed a minor leak. As the condition worsened, I brought the vehicle to an authorized Honda dealership for diagnosis. The dealer diagnosed the vehicle with a leaking A/C condenser and a leaking heat exchanger pipe and recommended replacement of both components. Honda declined goodwill assistance because the vehicle is outside the original warranty period. I later learned that Honda previously issued an extended warranty for A/C condenser failures on 2018–2020 Accord models due to a known condenser defect. My vehicle exhibits the same symptoms of gradual refrigerant loss and declining cooling performance, despite being a 2021 model year. In researching this issue, I found multiple reports from other 2021 Accord and 2021 Accord Hybrid owners describing similar A/C condenser failures and refrigerant leaks. I am submitting this complaint because I believe there may be a broader pattern affecting 2021 Accord vehicles that warrants review. I am requesting that NHTSA document this complaint and evaluate whether similar failures are occurring in 2021 Honda Accord and Accord Hybrid vehicles.

I am submitting this complaint regarding my 2021 Honda Accord because of a serious safety issue involving the turbocharger and fuel injector system. While driving on the highway, my vehicle experienced a failure related to the turbocharger and fuel injector system, which caused multiple warning sensors to activate and resulted in the vehicle suddenly losing power and becoming unable to continue driving. This unexpected failure forced my car to stop in the middle of the highway, placing me and other motorists at significant risk of a serious accident or fatality. A vehicle should not suddenly become inoperable while traveling at highway speeds due to a mechanical defect. This creates an extremely dangerous situation, especially in heavy traffic where other drivers may not have sufficient time to react. After researching this issue, I discovered that numerous other owners of 2021 Honda Accords have reported similar failures involving the fuel injectors and turbocharger. Given the number of reported incidents and the serious safety risks associated with these failures, I believe this represents a potential defect that warrants investigation. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and require Honda to issue a safety recall if appropriate. No driver should have to experience a sudden loss of power that leaves them stranded in moving traffic due to an apparent vehicle defect.

The vehicle suffered an unexpected loss of engine compression and dropped into a dangerous Limp Mode while driving due to a Cylinder 3 Misfire code (P0303). The manufacturer dealership misdiagnosed the mechanical issue using an unrelated 2.0L engine service bulletin (SB23-026) to clear the error. Six months later, the dashboard completely illuminated again with code P0299 (Turbocharger Underboost) caused by progressive pressure and compression loss across the 1.5L turbo engineering components. Upon post-visit inspection, engine fluids were found severely depleted. This ongoing engineering failure causes a sudden loss of vehicle motive power on public highways, creating a severe, recurring safety hazard that mirrors the active federal engine defect class-action litigation against American Honda Motor Co. This has happened 4 times with all the lights on my dash coming on Dec 2025, May 2026, June 2026 (2x)

The contact owns a 2021 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle decelerated and was hesitating while accelerating. The vehicle was taken to the dealer, where the spark plugs were replaced. The contact stated that months later, the vehicle experienced the same issue and was taken back to the dealer, where it was diagnosed with a blown head gasket. Two months later, the spark plugs were replaced again. Another two months later, additional components were repaired. The vehicle had been at the dealer for several months and the technicians were unable to determine the cause of the failure. The low engine oil warning light was illuminated, even though the engine oil level was not low. The dealer was unaware of the cause of the failure and stated that the engine needed to be dissembled for further inspection. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 133,000.
