Recently my traction control has been popping on for the slightest bump, or sometimes even on long turns the traction control light comes on stopping me from accelerating. Any ideas on what I should check? Problem recently started happening and is very sporadic. Really don't want to bring it to Cadillac to diagnose,

Sounds like you have a bad sensor. My fiance had a similar issue with her GMC Acadia. Think it was about $80 out the door. Granted they originally replaced the wrong sensor twice for $350

any idea on the sensor? I was thinking possibly a hub

I had a similar issue with a 2009 CTS. Landed up that the dealership had to replace one of the rear hubs because of a bad imbedded sensor. For an unknown reason, they couldn't just replace the senor and had to replace the entire hub. This was still under warranty at the time. Then it happened again. I had a bad wiring harness between the rear wheel and the vehicle computer control module.
