Multiple Problems on 2008 Tahoe

[Raleigh08LTZ]

I have taken my Tahoe into the dealership 4 times (about to be a 5th tomorrow). So far the dealership has not been able to figure out anything wrong with the Tahoe.

Problems:
1) Car intermittently won't start, but electronics and A/C etc. come on and function. No clicking or trying to turnover at all. Only thing that won't work during this time is the back hatch door, but glass will pop.
2) When the Tahoe does start I get "service suspension, service four wheel drive, service transmission" messages.
3) Transmission is slipping making the Tahoe very jerky to drive.
4) Cruise control not functioning.

Sorry if this is a repeat question from a newbie, but I am frustrated out of my mind. Any guidance is appreciated.

have you tried a new battery. Our tahoe battery got so low it would not start. Ended up using the F-250 to start it. Traction control light, Check engine light, came on security reset was flashing in the advisory. Engiine took longer than usual to start it ran like crap the Tach didn't work and the trans shifted hard into the gears. I took the positive battery cable of charged the battery. before I reconnected the battery I touched the positive cable to ground to get rid of any memory. Plugged it back up and everything was back to normal
