it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

SOURCE: 2005 yukon denali is overheating
Start it cold with rad cap off, and heater on high heat, and let it run until you see increased flow in radiator, indicating thermostat opened & engine reached operating temperature. Rev engine slightly every once in a while and hold it there for 10-20 seconds, just to help purge air better/faster. Watch rad flow again, and wait until you see increased flow 3 or 4 times. Then top up coolant in rad to an inch or 2 from top of rad, and put cap back on. Top up return bottle to appropriate level on bottle & then try it again. If it still heats up, get back to me. Does it overheat at all times? Rad fan is good i take it?

the system will need to be scanned to get the code. This will pinpoint the problem. These trucks are common for crash or collision sensor failing

It's a very dangerous situation you're in. The main thing now is safety so I would disable the air bag 'till you get to a mechanic. Disconnect the battery overnight to discharge power to it then take (usually) 2 screws behind bag on steering wheel off and yank horn pad/air bag (usually 2 clips) and disconnect the wire(Not the horn wire).
