I have this same issue of the battery not starting after parking the vehicle for over 2 hours
Its a Mercedes Benz Ml 350
2008 model
I have taken it to so many rewires but all to no avail So I just keep removing one battery terminal every time I am going to park it for over 3 hours

Could be some of the following... Bad rear SAM, faulty modules, short circuit,aging battery,stuck relays. Basically,anything that has to do with wiring.

Yeah I think you are right bcuz I just bought a brand new battery but the same thing is still happening but once I remove one battery terminal it starts one hand even after 24 hours

Get a good scanning technician to run full diagnostics to pinpoint the root cause cos removing battery terminal can affect the car ECU and other component in the long run. The OP here can help you do that
