   The car's infotainment system constantly glitches out and changes channels,outputs,texts,videos while car is being driven. It's very distracting and dangerous. It will literally do it 100's of times within a short period. It's much worse than any text messaging distraction, which is against the law. Several people with this car have the same issue. Also the car will break when there's actually nothing in the road that should make it break but it will just slam on the brakes.

   Vehicle started flashing all lights on dashboard. I drove it for awhile and then it eventually went off. A few days later same lights came back on a car started misfiring. Was told by Honda that is was the Turbo that's going bad. Today is just cut off on me. Luckily there wasn't anyone behind me. I see a lot of people are having these same issues and a recall should be put out immediately.

   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.…

   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.…

   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.
