Slip light on and VDC light on plus having problems with starting the car
That says you have a problem with the stability control system. A computer check can tell why that is.
Not likely related unless the check engine light is also on. So is it on? And how long has it been on? How many miles on this car?
… and if the CEL is lit-up, that is a likely cause for the other lights to be lit-up.
Unless the engine is operating at its optimum, stability control will be disabled, along with cruise control.

Is your battery in good state? Not causing ECM/BCM to think battery was off?
