(I've searched)

My vsc abs and vsc-off lights come on while driving my gs4, however when I shut the car off and turn it back on the lights are gone; that is until I drive the car again. The first mechanic stated that my problem was mechanical and that I have a problem with my driveshaft. He said that if I drive the car hard from a stop that I would damage my rear axles.
The second mechanic stated different and ran codes that showed all 4 wheel sensors were faulty. He said that he took all the harnesses apart and cleaned the parts necessary, drove the car for 25 miles and everything seemed fixed.
When I picked the car up and drove it half a mile; made a right turn the lights popped on again. I shut the car off, cranked it again (no lights) mashed the pedal to the floor a few times in park and the lights came on again.
Any idea of what this may be.

 

What were the codes the second mechanic read? You also need to know if the new codes are all the same as the old codes.

 

Thanks, but the problem turned out to be an overcharging alternator.
