I started receiving Service Brake Assist message on my 2018 GMC Terrain Denali. Took into the dealership and was told it needed a new battery. Put a new battery in, the exact same model battery that came in the car. I have now received this message, Proactive Alert SAC005. I received it about 1/2 hour before I put the new battery in on 1/6/22. I received it again this morning, 1/13/22. Any suggestions on what it could be? I already paid $160 to find out it needed a new battery for the service brake assist message and I know they will charge me the same to troubleshoot it again. I appreciate any suggestions!
