this is weird when I first start my car in the morning everything is fine after that any other time of the day when I start my car I get 3 warning lights one is the air ride suspension light, the ESP light , and the ABS light but everything works fine like it should , the next day when I start my car I get no warning light until I shut it off and restart it anyone have any idea what might be going on ????

Pull the OBD codes with a scanner that will "talk" the ABS and other systems beside just the engine. The problem was probably temporary and tripped the lights. ABS does some self checks on start up. If it senses an issue, it will trip the light. Sometimes the issue will not pop up on the next start up sequence and thus not trip the warning light.
