False collision warning on other CR-V years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2020, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
This group is about the forward collision warning itself. Owners describe alarms with nothing ahead, a forward camera that fails or reports itself blocked, and other safety features shutting off at the same moment. A lot of them happen at highway speed, and a lot end with a dealer who couldn't reproduce it.
What got replaced
Owners who name the part that was replaced mention the radar sensor (4 reports).
Recalls and investigations
No recall on collision avoidance covers the 2021 model year as of Oct 2, 2026.
When it happens
Too few of these reports state a mileage to give a range.
What owners wrote
“I was approaching an exit on the highway going about 60 mph when my car braked suddenly causing rapid deceleration. I was not touching the brake pedal and in fact tried to push the accelerator to no effect. Only lasted a few seconds but very frightening as there were cars behind me also driving at that speed.”

“I was driving past a school zone at 20 mph, came to a stop to allow children to cross street, as I began my acceleration past the school crossing, I reached a 20mph speed again and my CRV activated the emergency braking system without having anything in front of me that could have activated the forward collision braking system. Luckily I was not rear ended.”

“The forward collision warning and braking has activated a couple of times without any car front of me for a wide distance or when everything is all clear. It also happened a couple of times when turning a curve or exiiting, also without any car in front of me. The only thing I could notice was the dashboard flashing but I could not read it because I had to focus on the road.”

“My vehicle lost brakes as I was driving. The dealer stated it was because of wiring problem but I read where crv were having a problem with the accident mitigation system. They replaced my wiring harnes to my rear view mirror. The dealer couldn't explain why I lost power to my brakes.”

Should you keep driving it?
This page can't tell you that. 0 of 28 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
