False collision warning on other Pilot 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, 2017, 2018, 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 owners wrote

“CMBS activates for no reason whatsoever. I can't even count how many times this vehicle has locked the brakes up and no cars anywhere near me at all. Like miles down the road. Honda said they can't replicate the issue. Well, it's going to be hard to replicate something that happens 4 or 5 times in a week by driving it 10 min down the road. This vehicle is going to get my family killed.”

“My vehicle activates CMBS randomly. There doesn't even have to be cars around me and it'll just lock me up in the middle of the road. I have almost been rear-ended several times now. The dealers won't do anything about it.”

“Phantom braking from the CMBS collision avoidance system. It occurs randomly and applies brakes when the road is clear. The amount of braking varies from a partial second to more severe. This will cause an accident.”

Filed Mar 5, 2024

“The sensors alerted me to Brake in an emergent flash and then slammed the brakes - when there was nothing in front of me. It happens when the car is going faster than 45 mph. It has happened on three separate occasions and the third time almost caused an accident on a two lane road traveling 55 mph”

Should you keep driving it?

This page can't tell you that. 0 of 46 reports involved a crash and 1 people were hurt. 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.
