Driving 35 mph in my 2019 CRV EX, and all of a sudden, the brake started braking on its own. There was no warning, and the brake warning light came on several times with the brake braking on and off several times. There were not any objects, cars, or obstructions around. We (friend as passenger) came to a sudden stop when the braking first started up. It felt like major whiplash with jerking like motions. This lasted about 5 seconds and was just shocking. Our chests hurt afterwards, and it felt like the life was taken out of us. I was not using the cruise control/CMBS on at the time, but it was on to use if needed. I called Stirling Honda the next day about the problem and scheduled an appt. to bring the SUV in 6/22/2023. The lady did not seem to be too worried in my opinion. I actually have not been using the cruise control and CMBS at all, and actually have disabled it (turned off). This is a big safety concern, and thank God there was not a car in front of me or in back of me. I cannot imagine being at a higher speed and this happening.
