[Childs Play]

Probably best to take it in to let the dealership look at it. However if there's no check engine light, they may just say there's nothing wrong.

However it never hurts to stop by and ask.

I had my front bumper being repainted due to a problem at the dealership and they unplugged something related to the ABS somehow..? It started sending me all sorts of alerts through onstar. I called them to report it and at first they said they had to order a new module as the other one went out. Turns out, they had unhooked a harness somewhere when pulling the bumper off... Good ole dealerships...

However the issue was fixed and hasn't reoccurred.

blah blah blah. Take it in and let them take a look. It may have just been a fluke. However, better safe than sorry.
