Car stalls sometimes on idle and traction light comes up?

The car stalls sometimes and when I start it again, traction light shows and the car misfires but goes back to normal again. This keeps happening. I ran a diagnostic check and got the codes below.

ECM (Engine Control Module)-Leaded All 2 problems exist
1.P0011 'A(Intake)' Camshaft Position-Timing Over-Advanced or System Performance (Bank 1)
2.P0335 Crankshaft Position Sensor 'A' Circuit

ABS (Anti-lock Braking System) 6 problems exist

1.C1101 Battery Voltage High
2.C1260 Steering Angle Sensor Circuit-Signal
3.C1283 Lateral G Sensor /Longitudinal G Sensor/ Yaw Rate Sensor: Signal Error 4.C1613 CAN Signal Error ECM (Check ECM)
5.C1688 MDPS Signal Error History
6.C1285 Longitudinal G Sensor Not Calibrated.

I am wondering if these are serious issues that should make me return the car back to the dealer or something I can have the mechanic down the street work on without spending a fortune.
