Thread: 07 grand prix abs trac light on

i jsut bought a 2007 grand prix gt supercharged and dealer told me they would fix abs and trac light but there to stupid to figure it out so they replaced module and harness and trac button. what happens is the abs and trac lights reset everytime i turn car off and comes back on after a mile or two also there is a humming noise in dash and the dealer has replaced two radios cause on the digital display of radio the center light is out and know brakes are slipping alittle what do i need to tell them to fix i hate to give them the car back my wife loves this car and its fast as hell thanks

when key is on and when its running

ive read other post about this problem and they are saying hub assemblys but that cant be my problem i think electrical

i checked them there good but on the digital readout there off by one or 2 psi

would the sensors cause the brakes to slip alittle

also they found melted wire that connnects to the trac button next to cup holders

it seems like the lights come on after i hit a bump in the road now

it feels like a long pause in the pulsating aspect of abs brakes like 3 to 4 seconds of tension on brakes when it should pulsate really quick
