when I arrive in morning the car is sitting down with air shocks deflated, but not always, just every now and then, seems to be getting worst.

All 4 are low? Could be a stuck bleed off valve or relay doing that. Might need to have the BCM scanned to see if it has stored or seen any failures in the system. Also look for any obvious physical damage to the air bags

Only the rear two shocks let the air out, but sporadic, what is bcm, and no there is no visible damage. Have had three mechanic try and find out what the problem is and they could not. Also cruise control is sporadic. Is there some computer/board that could be malfunctioning?

BCM is the Body Control Module. Have it scanned. Pretty sure the valves are on the motor for the rear shocks, most likely the valve or motor itself has a slow leak. Might need to go to the dealer for this one, they will be more familiar with the common problems of your vehicle
