Since i brought my Gs3, i always had a short problem. its finally getting to me, everytime i open my ac and drive or just drive a little harder my ABS, VSC, and VSC(off) lights turn on. 3 lights at the same time. i tired pressing the VSC off button the bottem console but that does nothing. when this short happends, i feels like my car is weaker, losing power. any thoughts?

 

Is the CEL light on? Do you get any codes?

 

i think its a loose air hose to the intake

 

if you can hardly break, then ur break booster is broken.
i just saw the 3 lights last Saturday and my break is hardly working.
i took it to the dealer and they told me i need to replace the break booster (a control chip?), and it will cost me $2000(part + labor)....
a few CL memebers also had this problem, and some stated that 2nd Gen G4 with 100K milage might encounter this problem.

 

If the brake booster fails, usually it means you're going to have to apply more leg power to the brake pedal for it to stop. But if your push down on your pedal the same way as before, but the brakes feels a lot weaker, it could be your master cylinder. For the most parts, brake boosters are generally reliable. It's the master cylinder that endures all the pumping action.

In any event, one or both of these can go bad. But I rather have a failed booster than a failed master cylinder. If the MC is completely dead, you wont have any braking power AT ALL.

 

My 3 Lights just came on today, I replaced my suspension, sway bars, and bushings last night. I had to take one of the calipers off, and got air in the brake line, Im thinking this is my problem, It might just be yours. If your car brakes fine, Get a second opinion.

 

If you touched your suspension, you probably pulled onto the ABS sensor wire. It happens to a lot of guys on here who install new suspension without carefully removing/installing the cable hanger.

 

i just finished replacing both the drivers side and pass side tie rod and ball joints and now all 3 lights are on, any suggestions? what could have caused that to happen?

 

i cant really tell, about the braking but it feels i have to gas it more, because it feels as if my car lost power o_o.

 

get your car scanned for codes and I'll check up on what's wrong.
