Stabiltrak, Traction control

[mrkrausman]

My wife was stranded last night in our 2009 YukonXL, 49k miles. Vehicle went into limp mode (wouldn't drive over 20mph) and she reported shaking as if a tire had blown. Message read: 'engine power reduced, service Stabiltrak, service traction control.' Vehicle was towed to dealership. Any ideas here on what's going on or what to expect on a diagnosis this coming week? Thanks in advance I am a first time poster. We are concerned because we are taking it on a long trip in two weeks.

Thanks for the help.. It was the throttle body module. See ya. The worst forum I've ever been on. Hurry moderator and erase me.
