ABS, Traction control and Active Handling.
Has anyone had a problem with these three lights coming on? My 07 coupe had them come on last year. I had it checked out and nothing could be found. A few days ago it started again. It seems to come on when I hit a bump.

It is pretty common.
It's possible that one of the wheel speed sensors has just come loose a bit or isn't making a good connection due to a bent pin or dirt/grime. I disconnected all of mine, cleaned them and plugged them back in and it resolved the issue.
Some people might say things about the steering wheel column, but it has nothing to do with your issue as that only effected active handling.

What did you do to have it checked out? Find out where you can get the codes read with a scanner that reads ABS codes. If it can't read ABS codes you won't see anything. When the lights come on stop and get the codes read but do not turn off the engine until after they are read.
The EBCM resets upon each engine start so if you turn the engine off and plug in the scanner and then turn on the ignition some of the codes may disappear. Since you are getting Service Messages from all 3 functions of the EBCM that means the failure is common to all 3. Wheel speed sensors are common to all 3 as are proper voltage and ground to the EBCM and the EBCM itself.
