Hi everyone,
I just bought an 08 gxp with 75k and just started having some problems. Twice know while I'm driving down the road the service traction control, abs ans stabilitrak light comes on. Looking at others posts it can be anything from a loose wire to a speed sensor. Also there is buzzing coming from the dash and I can't seem to disable traction control by pushing the button "TC" button. Is this all related? Did I just by a lemon?
 


check for a bad hub or torn up wire to the hub. if you cant find anything get the car scanned at a garage. the code will tell you where to start.
 
All right I've got another update. Whenever I start the car as soon as I turn the wheel there is a growl/vibration I can hear and feel coming through the brake pedal. The last time all my abs, stability, etc shutoff it made that noise right before it happened.
 
Sounds like a bad wheel bearing in the front..I have 110k on my gxp and have been through 3 sets of front bearings..40k, 80k and now just swapped them 110k..gxps eat them up..first 2 were gm bearings under warranty, last set I installed were timkin..jack front of car up and feel if u have any play in wheels, thats a sign of bad bearing..then check for frayed speed sensor wires...get the abs code read like scotty said and u will know exactly.what it is but my guess would be bearings..good luck.
