2021 Honda Accord

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

In many Hondas, Toyota, Kia, Hyundai you name it they have this flaw. If it is dark out and headlights are needed but they have bright running lights people will be driving around without taillights and the cars won't say a thing, I think headlamps suggested messages should appear on their dash so they know they have to turn them on or auto headlights that can't be disabled should be mandated on all new cars

I am submitting this complaint regarding an ongoing safety concern with my 2021 Honda Accord. Multiple lights indicate engine system problems which includes, check engine light, car jerks at acceleration, seat sensor recall. I took my vehicle to multiple shops including the Honda Dealership. However, they were unsuccessful to identify the cause. Multiple problems such as Turbo, belt, fuel system problem constantly comes up. I have attempted to take my vehicle for the recall, which was scheduled, however after waiting 4hrs, the dealership stated they did not have the parts. I am concerned about the potential risk to myself, my daughter and my passengers and believe these issues warrant further investigation to help prevent possible accident or injury.

Vehicle: 2021 Honda Accord Sport Subject: Intermittent Electrical Malfunctions, Multiple Safety Warnings, and Loss of Acceleration I am reporting ongoing safety concerns involving my 2021 Honda Accord Sport. On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approximately 65 mph, these warnings had already been displayed for approximately 30 minutes to an hour when my vehicle suddenly began struggling to accelerate. Despite pressing the accelerator, the vehicle continued losing speed, and the RPM gauge remained around 2,000 RPM. It felt as though something was holding the vehicle back. After several moments, the vehicle suddenly regained power, accelerated, and the RPM increased. This was particularly concerning because I was traveling at highway speed. I also experienced electrical problems with the interior lights. While the vehicle was running, neither the automatic interior lights nor the overhead lights near the rearview mirror would turn on. They remained inoperative after I turned off the vehicle. Later, the lights began working again, but I noticed the right overhead light fading while the left remained illuminated. The battery was replaced earlier this year, in 2026. I am concerned that these intermittent malfunctions could result in a sudden loss of power or failure of important vehicle safety systems while driving. I am requesting that these problems be documented and investigated for a potential safety defect or recall. I have photographs of the dashboard warnings available as supporting documentation.

Infotainment System glitching: "ghost touch"; the screen is not registering my touches and randomly selecting/pushing buttons all on its own. Took it to Honda dealership and they have no answer or fix. This happens from time to time while driving, causing a huge safety concern. Extremely distracting to me, the driver. Everywhere I go to get answers, I only get "issue is known to manufacturer but no fix available; they are currently working on a fix". This has happened multiple times intermittently since I've purchased the vehicle in 2021.

The contact owns a 2021 Honda Accord. The contact stated that while his wife was driving at 65 MPH, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. The vehicle hesitated and then accelerated; however, the vehicle then failed to accelerate above 20 MPH. Several unknown warning lights illuminated. The contact's wife drove the vehicle to a safe location and parked. While attempting to start the vehicle, the engine started and then shut off. The dealer was notified of the failure, and the vehicle was towed to the dealer, where it was diagnosed with a fuel pump failure requiring fuel pump replacement. The contact referenced a recall with a similar failure description; however, the contact's VIN was not included. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 152,100.

I bought my Accord in February of 2026 with only 79k miles (now at 93k). 3 days after purchasing all of these warning lights popped up regarding emissions, brake system, power steering, etc. I brought it back in and they said that it needed a new fuel injector on cylinder one (which didn’t fix the issue). I have replaced all 4 spark plugs and kept up with maintenance since it has been in my ownership. Now I’m having issues with the car going in limp mode, decreased acceleration, decreased mpg, and constant misfire codes! I do not feel safe in this car anymore since it has almost left me stranded as well as it disabling the safety features which could put me at risk. Honda desperately needs to fix this issue seeing as it’s putting their customers at risk, along with others on the road. NHTSA please do something!
