I recently purchased a 2006 CTS V and a few weeks ago it started having an issue where the front left break will lock up while I’m driving pretty much after the front end bounces weather it’s a bump going onto a bridge or something that makes the front end bounce a little. When I press on the brake it stops the brake from locking and it doesn’t happen all the time or immediately after going over something it is slightly delayed and I can sort of feel it about to happen. When I put my foot on the brake I can feel the abs activating but I don’t have any abs light show up on my dash just a check engine light with the codes C0186, C0196, C0146, P0833 most recently after clearing them to narrow down the issue but I have also gotten codes C0253, C0460, C0461 and some others that I think were just history from the previous owner. This car also has a pioneer radio and subs in the back and the battery date is 10/19 if that is relevant most of what I have seen says it is possibly an electric issue. I’d really appreciate if anyone knows anything about this, please comment if you need more information or pictures if I can do that I don’t know this is my first post but thank you!
