Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I was driving on Route 42 today at around 3:45 and my brake light flashed across my dashboard like I needed to step on my break because there was something in front of me but there was nothing in front of me. This has been going on for over a year now I have reported it multiple times and I'm just trying to see if you guys are going to fix it or inspect it I've cleaned off my radar also to make sure that wasn't the problem and it still does it

I was driving down the road, on Pinewood rd Sumter sc 29154, the front camera sensed something in the road but nothing was in the road I didn’t brake because I didn’t see anything in the road the orange brake light flashed on dash, so the car did a hard brake of its own, it jerked me the driver I had a sore neck and upper back area for a day due to the hard brake that jerked me. I continue to have phantom braking but I brake when this occurs to avoid hard jerks. I have not yet taken to the dealership.

There has been no incident with my vehicle but I am writing to look into this issue. I see several threads online regarding these warning lights that just randomly pop up without any indicator of a problem with the vehicle. This stops all these assistive features from responding if there were a hazard. Please look into this because Honda is not responsive to the recall issue.

While I was driving on the highway, the brakes of my car suddenly were violently activated and I had not touched the brakes. If there had been a car behind me, it would have been a major rear end collision. It was over quickly and I accelerated back to the normal speed. I talked to the Honda Service Mgr where I purchased the car and he said he was unaware of the problem although I see that that nearly 3 million Hondas have experienced this issue.
