Important! Brakes gone wild!!

Intermittent StabiliTRAC engagement is a known problem with a TSB to perform corrective action (installation of a keeper to prevent fretting) on a connector at the base of the steering wheel. Other causes can be a bad Steering Wheel Position Sensor, (part of the signal path of the connector I mentioned) or a bad Yaw Sensor behind the infotainment unit.

The most common cause I've seen for this, (across all Cadillac models equipped with this feature) are faulty wheel speed sensors, located within the hubs. This makes sense, since there are four of them to go bad.

When any of the input signals don't jive, and it appears the car is going into a skid and the steering wheel position doesn't match up with the expected rotation, the Electronic Braking System tries to right the car's path by applying the brakes on the opposite side it believes the car is yawing (rotating) in relation to.

No need to dump the car, just fix the problem. Have a dealership scan the car, and perform the TSB.

In the meantime, until you get the issue resolved, keep your upholstery stain-free by disabling StabiliTRAC: Press and hold the Traction Control switch until it chimes two times each time you start the ignition. A message will appear on your DIC indicating both are disabled.

I've experienced this and it's white-knuckle scary. After it happened a couple of times, my wife was ready to have me fitted for Depends undergarments.

If you think unintended StabiliTRAC engagement is bad, (and it is) wait until the inevitable reports of the new automatic front and rear automatic braking systems engaging, (currently being installed on the latest models) trickle in -assuming the drivers live to tell the tale. In the rain. At night. . .

These safety braking systems are great when they work, (and 99.99% of the time they do) but if the Fickle Finger of Fate points in your general direction and you're cast in the .01% of its shadow. . . . Hello, PTDSS (Post-traumatic Driving Stress Syndrome) therapy.

CC. When this happens if you can react and not ruin your leather seats could you disable the T/C and the problem would stop ?John F.

By the time it happens and you regain control of the vehicle, (if required) it might be too late for your shorts. The only thing left to do is disable StabiliTRAC and continue to your destination.

Your choices are:

1. Repair whatever is causing the problem.
2. Drive with willful abandon, ignoring the Pucker Factor and savor those moments when the Fickle Finger of Fate points in your general direction.
3. Disable StabiliTRAC each time you start the car.
