I am having an issue with my used Acadia... It does have a check engine light but honestly I don't think an oxygen sensor will affect stabilitrak... But my issue is occuring at two different styles of driving... 100% of the time when I am braking WHILE steering or turning left.... And recently has started at low speed turning left and giving fuel.... DOES NOT occur at all when going to the right .... When the issue occurs in the left turn I can hear the abs pump or what I believe to be the abs engagings and giving like a grinding sound.... Once this sound starts the vehicle starts braking on its own and tries to lock up aka causing to slide... As soon as I can get my vehicle to steer right or after I let it do it's thing for a moment it clears up and drives like it should and the warning message "service stabilitrak" goes away until the next time... Anyone experiencing the same??? All 4 wheel bearings have been replaced and both front calipers.... I have noticed when braking in a straightway or to the right the vehicle will randomly pull to the left ...
