Defect investigations
Inadvertent Automatic Emergency Braking
On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations.  However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,294 consumer complaints of inadvertent activation of CMBS in 2017-2022 Honda CR-V and 2018-2022 Honda Accord vehicles. A total of 31 complaints alleged a crash and 50 alleged an injury. The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources. In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged. In total, there were X,XXX reports, 93 injury incidents and 47 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22-003 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. The scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles.

What 2020 Honda Accord owners say
Most recent owner complaints, unedited.
A mechanic inspected or evaluated the vehicle and told me that the small fuel filter/strainer inside the fuel pump assembly may be causing the problem. The vehicle has intermittent starting difficulties, rough engine operation, and sudden loss of engine power while driving. The accelerator sometimes becomes unresponsive until I pull over, turn off the engine, and restart the vehicle. I am concerned about a possible fuel delivery system malfunction and the risk of losing power unexpectedly while driving. I am requesting an investigation into the fuel pump assembly and its internal filter.
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.
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.
The contact owns a 2020 Honda Accord. The contact stated that while driving at 35 MPH, several warning lights illuminated. The vehicle was taken to the dealer, where the battery was replaced; however, the failure recurred. The vehicle was taken to three independent mechanics, where the failure was confirmed, and the battery was replaced; however, the failure persisted. The contact stated that the battery was replaced four times within three and a half years. The contact stated that the warning lights turned off temporarily upon replacing the battery. The contact stated that the failure was a common issue.
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.
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.
I was reversing my 2020 Honda accord and the power steering light came on. The power steering and steering wheel was hard. The steering then locked up. I couldn’t move the car. This could have been dangerous of another vehicle was coming. After shifting it back to drive, it went away. Now I am concerned the car may do this problem on the road.
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.
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.
