The service advisor at the Chevrolet dealership denied a repair to my abs control module because it was a -??known issue-??. He told my wife and I our car is unsafe to drive And still wants to give it back to us. Other Gm vehicles have recalls open for the same issue one needs to be open for this. Abs lights and multiple others no brakes or random braking.
