Forward collision avoidance
104 reports3 crashes
“The contact owns a 2020 Honda Accord. The contact stated that while driving at approximately 30 MPH, the Collision Mitigation Braking System unexpectedly engaged, causing the vehicle to come to an abrupt stop, and the vehicle jerked while there was no other vehicle or obstacle nearby. The local dealer was contacted by phone and advised the contact to bring the vehicle in for a diagnostic test. The failure mileage was approximately 82,605.”
Engine
73 reports
“On 09/18/2026, at 103,000 miles, my vehicle suffered a dangerous powertrain failure where numerous dashboard warning lights illuminated and the car suddenly dropped into "Limp Mode" with an immediate loss of acceleration while in active traffic. I took the vehicle to a certified Honda dealership, where technicians officially diagnosed the issue as a "Fuel System Too Rich" condition (Diagnostic Trouble Code P0172). The dealership confirmed that the factory-installed direct fuel injectors are failing prematurely and leaking raw fuel into the engine cylinders. This manufacturing defect causes severe engine oil dilution, where gasoline contaminates the oil pan, creating an immediate stalling hazard and an extreme risk of a high-speed rear-end collision. Online owner forums and dedicated global social media groups indicate that thousands of other 10th-generation Accord owners are experiencing this identical safety defect. Honda corporate has formally denied goodwill assistance, treating this severe engineering flaw as standard wear and tear. The vehicle and failed components are fully available for inspection upon federal request.”
Service brakes
56 reports2 crashes
“The contact owns a 2020 Honda Accord. The contact stated that while driving 5 MPH and attempting to make a left turn, the vehicle unexpectedly stopped, and the brake pedal was depressed while the vehicle was entering ongoing traffic. There was a burning odor coming from the vehicle. The contact stated that the vehicle unexpectedly lunged in the opposite direction while driving. The contact expressed concerns that the vehicle was unsafe to drive and that the failure could have caused a chain-reaction crash if the vehicle behind had not stopped. The contact did not feel safe driving the vehicle. The manufacturer was made aware of the failure via telephone. The failure mileage was approximately 78,000.”
Electrical system
55 reports3 crashes1 fire1 related recall
“Unknown cause - Heavy Traffic I get all warning lights (idiot) come on. No performance loss but every advisory and caution is illuminated. Tested battery 550amps and regulator was putting out 14 volts so all seemed fine. Check battery terminals and connections, all good. After two days lights go away and everything works fine. When lights and advisory are on, no cruise control, TMPS, lane departure, assisted steering, and anything else in the caution light display doesn't work. Good thing all other aspects of the car work fine. Unable to determine the issue with Why this happens. Seen on line others have had this same issue.”
Fuel/propulsion system
52 reports
“The high-pressure and low pressure fuel pump went out on the car and needed to be fixed. There is an open recall on 2020 Honda Accord however my VIN number is not a part of the recall and I think it should be as I have had to fix my low pressure and high high-pressure fuel pump before 100,000 miles.”
Air bags
36 reports3 crashes2 related recalls
“The Supplemental Restraint System Problem message along with the airbag light comes and goes on my dash randomly. Anytime I am able to take it to get scanned, it doesn’t show up. Then when I’m driving down the road it will randomly appear. It also appears sometimes when I first start the vehicle. My car has 66,200 miles on it and it first happened at 59,771 miles. The vehicle has never been roughly treated or heavy objects placed in the seats. I believe it is something electrical that is faulty because of failing Honda parts. My car shows there are no recalls for this, but other Accords do have a recall for this issue.”
