Has anyone ever had this problem ....

While cruise control is engaged (speeds around 70 mph), the car suddenly and aggressively applies the brakes with no other vehicle within sight.

This happens frequently. I’ve tried adjusting the “follow” distance and it doesn’t seem to make any difference.

Check the cameras and sensors to see if they’re dirty.

Is there anything about the environment you notice when it happens? For instance did you go under an overpass?

It has happened both at night and during the day on open highways (no overpass) and no precipitation.

Thanks for the suggestion to check the sensors and cameras. I keep the car clean but maybe I’m missing something in these.

It's called phantom braking and is usually associated with *something* the car is seeing. If there's nothing in sight, that might be cause for a service center visit.

When it happens, use the right scroll wheel to bring up voice commands, and say "bug report phantom braking event" (all one sentence).

It will capture a dump of information from the car and keep it for your next SC visit to analyze. Someone recently alleged that 'bug reports are now sent to the mothership as well for analysis'.

Even easier:
You know that little car symbol in the lower-left corner of the display that you use to open the settings menu?
Hold that down for 5 seconds. It will automatically generate a report. You'll see a notification that says something like "Thank you for the report".
