recently my traction light has been coming on this past week but last night the low oil pressure light came on.
my car has plenty of oil and isnt leaking as far as can be seen when started. the light comes on once the car has heated up.
today I turned the car on just to check and the ABS light or brake system light is now on as well
the servicing departments at chevy are closed till monday and I really need to know what could be wrong with it..

 

if the oil level is ok and the engine isn't knocking....it may be a bad oil pressure sensor....this should set a check engine light
abs and service brake light is unrelated. would need codes to know how to proceed.
