What 217 owners told NHTSA about the 2021 Honda Accord Fhev

On July 4th 2026, I was leaving from a restaurant that evening and within 5-10 seconds of me turning my car on, all of the lights on my dashboard turned on. I was slightly confused because there were multiple at once and my car was rumbling a bit from under the engine hood. Within a few weeks prior, I’ve been having with my digital car screen switching back and forth between tabs (from the radio, to my CarPlay, to the settings). It will be intermittent but fairly consistent. I plan to take my car to an auto parts store for a code test and battery/alternator test to see if there’s any further issues. I just purchased a new battery for this car within the 3 years of me getting it, 2 years ago and there shouldn’t be any issues. I’m not sure how to proceed and I really don’t have it in me to spend large amounts of money and time with repairs for a supposedly heavily reliable car. My current mileage is at 120,000.

Infotainment Center: I am submitting this complaint regarding my 2021 Honda Accord Sport and the ongoing issues I’ve experienced with its infotainment system. This problem has been persistent, unpredictable, and increasingly concerning from both a usability and safety standpoint. Since purchasing the vehicle, the infotainment center has repeatedly malfunctioned without any warning. The screen will freeze, switch from setting to setting, or become unresponsive to touch input. At times, it will randomly reboot while I am driving. These issues occur regardless of whether I am using navigation, Bluetooth audio, or even when the system is idle. This also affects the ADAS, periodically, warnings will be displayed, and then not show up. What makes this especially troubling is how it affects my ability to safely operate the vehicle. For example, when the system freezes, I lose access to navigation directions mid-route, which forces me to either drive without guidance or attempt to troubleshoot the issue while on the road. Similarly, when using hands-free calling or music controls, the glitches can be distracting and require repeated attempts to regain control, taking my attention away from driving. I rely on my vehicle daily, and this ongoing issue has caused a great deal of frustration and concern. A modern vehicle’s infotainment system is not just a convenience—it is integrated into essential driving functions. When it fails, it directly impacts driver awareness and safety. I am requesting that this issue be investigated further, as it appears to be a systemic problem rather than an isolated defect. I hope that by reporting this, it may help lead to a resolution for myself and other drivers experiencing similar problems.

The lights and warnings below popped up on my dash after the engine light had come on and then off again for about a week. See below, -Emission system problem Avoid heavy acceleration and high speed. See dealer -tpms light -brake system problem -brake hold system problem -electric power steering system problem -vehicle stability assist system problem -hill start assist problem -adaptive cruise control system problem -collision mitigation braking system problem -road departure mitigation system problem Went to get diagnosed at the dealership and was told that the turbo on my engine had failed. Mechanic said it had nothing to do with me and that it failed on its own. I saw that it was a reoccurring problem with other Honda owners with the same year, make, and model as mine but are being given the run around and no solution.

There are two locations in the town I live where I am driving under a bridge, and there is a dark shadow on the road from the bridge. My car’s accident mitigation braking system turns on at these locations and suddenly brakes the vehicle. This is not safe as people are traveling speed limit around me and I can cause an accident this way. About a month or two ago, the car behind me almost hit me at one of these locations when my vehicle’s automatic braking system turned on. It was made to prevent accident and brake if there is a vehicle, but because it is braking due to a dark shadow coming, it is not working properly and needs to be looked into. I called Honda and they want me to pay hundreds of dollars at my local Honda dealership for a diagnosis, I do not feel like I should be responsible for that fee as this is a safety feature that is not working as it should and instead making it less safe for me and drivers around me.

While driving the automatic brake system randomly starts flashing brake across the instrument panel and begins to brake the car. This does this while there are no other vehicles or any type of obstacles near the vehicle. It also, does it at random caution lights for the fire department on a 4 lane divided highway. There is no way to stop it from doing so. This happens frequently and leaves the driver with no control over the braking system.

This Honda Accord Sport SE has had electrical problems from the day I received the vehicle. Every time I went for an oil change at Bommarito Honda I mentioned it to them and they said “yeah the new Hondas do tend to hand a lot of those electrical problems” so with this the problems continued to get worse. Sometimes the buttons do not work, sometimes they do, sometimes the lights don’t work and sometimes they do and sometimes the safety features and break system automated itself. I have slammed my head on the steering wheel on multiple occasions. I believe this needs to be looked into because the malfunction of the car falsely reports danger and caused an accident. Yes every time it malfunctions it flashes briefly and so quickly on the screen .

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle’s collision avoidance automatic braking system is malfunctioning. It engages unexpectedly while the vehicle is moving with normal traffic flow. The system is still installed and fully available for inspection upon request. How was your safety or the safety of others put at risk? The automatic braking system activates suddenly and without cause while I am driving at typical speeds (approximately 40–60 mph) with the flow of traffic. This unexpected braking creates a serious risk of rear-end collisions, both endangering me and putting other drivers at risk of crashing into my vehicle from behind. Has the problem been reproduced or confirmed by a dealer or independent service center? I have reported the issue to the dealer, but they have been unable to replicate the problem during their inspections. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? No, the vehicle and its braking system have not yet been inspected by the manufacturer, law enforcement, insurance representatives, or any other third parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, messages, or other indicators were present before the issue occurred. I purchased the vehicle last month, and the problem with the collision avoidance braking system has been present consistently since then.

The touch screen is malfunctioning. Its "ghost touching" as in the screen is pressing random buttons on the screen at random times while driving. It can change and has changed settings while driving (distance for breaking before a collision, etc). While its touching random things on the screen im unable to touch anything on the screen. As if its locking me from pressing anything.

My car slammed on its own brakes hard out of nowhere with nothing in its forward. The first time it happened was about 9 months ago while I was driving on the highway, it was a quick moment of breaking without any reason, but the car didn't stop. Today it happened again, the speed was about 30 m/h, the car slammed hard on the brakes to an almost complete stop. I was lucky, nobody was behind.

Automatic breaking engaged with foot already pressing down brake pedal as traffic ahead was slowing. The automatic braking was overkill that the traffic that was slowing down ahead of me was now pulling away.

I saw that they are investigating Honda Pilots for an automatic braking issue. I wanted to report that on my car I’ve had the automatic brake warning come on at least 3 times while driving at highway speed with nothing in front of me. This is over a period of 3 years (my car has 40k). The brakes didnt engage, but it alerts you like it will engage for a couple seconds then the alert goes away. It could be related to the Pilot issue. If the brakes did engage I would likely get rear ended on the highway. So far it hasnt happened but it is scary when it does. And totally random as each time no car within 2000ft

Lane keep assist continues to jerk the wheel from my hands with false lane departure warnings. Especially in direct sunlight. THIS HAS BEEN REPORTED TO YOU 100'S OF TIMES AND NOTHING HAS BEEN DONE FOR 4 YEARS. HOW MANY MORE PEOPLE HAVE TO BE KILLED AND INJURED IN HONDAS BEFORE YOU ACT?

The infotainment system randomly presses all over the screen all the time. This causes tony of issues such as turning on the radio, changing navigation, and making beeping noises constantly. Honda has replaced the infotainment system twice in my vehicle and it has fixed absolutely nothing. This is a major safety issue because of how distracting it is when driving. The incessant beeping noises (it beeps every time the touch screen is “pressed”) makes it so that I don’t know whether the car is beeping for safety issues (lane assist etc) or not. The radio being turned on at random is extremely startling and has caused me many near accidents. The navigation turning off as I am navigating through traffic has caused much stress and confusion which can lead to an accident. This is a major issue that needs correction ASAP.

Driving on Highway at approximately 65 Miles Per Hour using the Adaptive Cruise Control. Car in front of us took a right hand exit. My 2021 Honda Accord activated the Braking System and applied the brakes, so I stepped on the accelerator thinking it would override the braking system. It had no effect. There were cars behind me at the time and luckily nobody was injured. I looked this up on the internet and found that it is a reported issue. That is why I am contacting you. Very concerned about the safety of my family.

My honda Accord’s automatic braking system suddenly engaged this morning for no reason. The driver of the car following me had to slam on his breaks to avoid rear-ending me. If the other driver had not stopped, we would both have been injured. Honda’s emergency braking system is dangerous. There should be a way to disable it permanently.

Rear seat belt will not click and lock in. With the forward collision warning there was times I was driving on the freeway where there is no vehicle in front of me and Hard brake on me and shows forward collision warning. This happened like 3 or 4 times

I was driving 35mph and there was nothing in front of me when my car stopped. It would not move forward or accelerate despite pushing on the gas pedal. There was no forward motion or propelled motion. It took several seconds for my car to go again. The car was towed and serviced at the dealership. They said the front sensors had misfired. If a car would have been behind me or if I had been on the highway, this would have been a serious accident. The engine light never came on. A series of 5 warning lights related to the assisted driving came on but went away.
