That's crazy. BSM still works most of the time but when driving around town, after several minutes it starts flashing, but only when above about 75 outside. Does not happen in winter. When going on the interstate it will eventually revert back to normal due to airflow. Window is set to non-smoker preference, but I will have to try that reset. Funny because the first time it ever happened was when I put the window down one time on the interstate...
Mine started flashing one day last week on the way to work. It came on again on the drive home. It did not come back on the next day and has not come back. Weird. First time that has happened in 10 years of ownership.
...and the same thing just happened again, six months later. On for a couple of short trips one day last week and then back off. No idea why.
Hey, in case this helps. We had the same problem with blinking BSM light on the dash, 2008 CX9. Then we also noticed the "one touch" window system didn't work. Windows went up/down but you had to hold the button. It seems when the battery in the car dies the car forgets how the one touch windows work. So we reset them and now the BSM blinking light is off (went off with driver window reset). Go figure. Turn on car (no need to start it), open window all the way, then close it all the way and hold the button for an extra 2 seconds. That resets the one touch window system and in our case turned off the blinking BSM light.
Thanks for the tip. I had ours washed yesterday after reading your post. Still blinks. I let it cool down. Still blnks. Then when I got home I crawled under the car, hand washed the sensors and inside fender/bumper on both sides, checked the wires to make sure they are plugged in. Still blinks. I give up!I owned a 2008 CX-9 until last week (bought a 2020 CX-9). For the last 4+ years, I had the "BSM Off" problem. It would come and go--probably related to the heat. A car wash always solved the problem, either by cooling down the sensor or cleaning it.

Welcome to the bsm off club. I have deducted it has something to do with proximity to mufflers. Since it seems only to happen to me when it is above about 65 or 70 outside. Never happens in winter. Annoying in the summer. The modules in the rear bumper are next to the mufflers on either side.Mine started flashing one day last week on the way to work. It came on again on the drive home.
