2020 HONDA ACCORD Complaints

The vehicle would stop accelerating despite still applying pressure to the gas pedal. Feeling as if no field was being allowed to flow through.

- Component/System failure/malfunction: ADAS. Specifically, CMBS and/or ACC. - My car has repeatedly experienced unexpected braking events, rapidly bringing me to nearly a complete stop in the highway. During this time, I have no ability to control the speed of my vehicle. This has been occurring during my ~70 mile commute on I-675, I-75, and I-275. - Despite having the car on multiple occasions and for over a week collectively, the issue has not been replicated by the dealer. - The vehicle has not been inspected by the manufacturer, police, insurance representatives, or others to date. The Honda dealer has not initiated any further inspection. - During these failures, the car has (often) been braking without due reason or any alert to the driver. No system malfunction was found (either shown to driver or in computer log, as verified by dealer). Please review attached document for further details regarding the incident(s). This copy has been presented to Honda and the Ohio Attorney General.

Subject: Turbocharger Underboost – Safety Concern on 2020 Honda Accord EX-L I am reporting a serious safety issue with the turbocharger system on my 2020 Honda Accord EX-L with the 1.5L turbocharged engine. The vehicle has repeatedly triggered Diagnostic Trouble Code P0299 (Turbocharger Underboost), indicating the turbocharger is failing to generate sufficient boost. As a result, the vehicle suffers from sudden loss of power, especially during acceleration and highway merging. This power loss occurs without warning and severely impacts my ability to drive safely in traffic, increasing the risk of accidents. There are currently no recalls or manufacturer advisories addressing this issue, despite numerous online reports from other Honda owners with the same engine and problem. This suggests a possible design flaw or premature component failure in the turbocharging system. Given the frequency of this issue and its impact on vehicle safety, I am requesting that NHTSA investigate this matter and consider whether a recall or manufacturer service campaign is necessary. Symptoms include: •Sudden engine power loss •Error code P0299 •Inability to accelerate safely •Safety risk during lane changes and merges First occurrence: April 20, 2025 Ongoing issue: Yes Mileage at first occurrence: 111, 000 Crash or injury: No Thank you for your attention to this matter

Just like the 2018 Accord in Still Night Pearl (addressed in TSB 21-087), the paint has peeled and failed on the roof line by the rear glass. Called Honda, they don't care to address ANY vehicles with this KNOWN paint defect any longer. Now we have to pay thousands of dollars out of pocket to get it resolved or the steel will start to rust. Will NEVER purchase a Honda ever again.

Car reached 113,000 miles and started having misfires in cylinders 1&2. After being told it needed new coil packs and spark plugs, and replacing those it is still misfiring. Paid for diagnostic again and was told cylinder 1&2 were wet and most likely it was the head gasket failing.

Starting sconce July the car will vibrate at random times and will hesitate and buck while car will vibrate and not want to move have brought the car back to the dealership over 4 times now and they can not find any issues despite me having videos and any information I can gather since July if 2024

•Alleged Defect:?The defect is described as the engines' inability to handle the increased heat and compression of a turbocharger, causing coolant leakage and damage to the engine's head gasket. ???

I had an appointment today (4/18/2025) at Causeway Honda in Manahawkin, NJ to remedy the recall of the 2020 Honda Accord seat weight sensor circuit board. When I got there Amanda from the service department said they cannot fix the issue because Honda will not pay for it. She said that they are only fixing cars that has an SRS indicator illuminated on the display panel.

Mechanic said there was a fault in the hi pressure fuel injectors that’s causing the engine to run rich

Detailed Statement of Defect and Manufacturer’s Acknowledgment – Honda Fuel Pump Recall (2017–2020 Acura and Honda Models) Overview of Recall: On December 21, 2023, American Honda Motor Co., Inc. publicly announced a voluntary safety recall affecting approximately 2.6 million Acura and Honda vehicles in the United States from model years 2017 through 2020. This large-scale recall concerns a critical defect in the fuel pump system that has the potential to cause engine stalling while the vehicle is in motion, posing a serious safety risk. Technical Description of the Defect: The issue stems from an improperly molded fuel pump impeller—a component responsible for fuel delivery within the pump. The molding defect results in the production of low-density impellers that are prone to deformation. Over time, these impellers can degrade and interfere with the fuel pump body, ultimately rendering the fuel pump inoperative. Should the fuel pump module fail during vehicle operation, the engine may not start or could stall without warning, which significantly increases the risk of a crash or injury due to the sudden loss of engine power, particularly at high speeds or in heavy traffic conditions. Manufacturer’s Response and Limitations: Honda has stated that it will replace the affected fuel pump modules free of charge, and claims that no crashes or injuries have been reported at the time of the announcement. However, it is critical to note: •Countermeasure replacement parts are currently unavailable in sufficient quantities to address all recalled vehicles simultaneously. •Honda plans to notify vehicle owners in stages, with initial notifications to begin in early February 2024, followed by additional notices as parts become available. •This delay in availability and communication may expose vehicle owners to ongoing safety risks without immediate remedy. Legal and Consumer Impact Considerations: While Honda has initiated recall efforts, the scope and severity o
