Terrain side detection



I get a message on my 2016 Terrain Denali saying the side detection module needs maintenance. After receiving this message, my car was hesitating to start as if the battery was going bad. Battery checks fine. The dealership checked the codes and nothing shows an error. The next day the car will not start. Now the dealership says the module needs to be replaced and a new battery and they cannot disable the system which is draining the battery. Anyone else have this problem.
