My 2007 pontiac torrent service engine is coming on an off, the reduced power engine, traction control and service stabilitrak warnings are coming on periodically approx 6 times over the last few months. Then today for the first time my car stalled at a traffic light then when I turn my car off and back on all of the warnings come off.

Very common. GM has issued a service bulletin for this. Read this post

Engine power reduced... is the main problem ,this turned off Traction control off, service stabilitrak. Your vehicle has electronic throttle control , The Gas pedal has sensors inside which are connected by electrical circuits to the PCM - engine computer ,the PCM use's these inputs to control the throttle plate by use of a 12 volt DC motor . Plus there are position sensors on the throttle body for feed back to the PCM. When one of these signals is off The PCM will put the system into reduced power mode . This will also set DTC'S - diagnostic trouble codes . Your best bet , take it to a qualified repair shop.

Probably a sensor. I would just drive it.

StabiliTrak Indicator Light: If the warning light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly.

This light will also flash when the StabiliTrak system is active. If the StabiliTrak system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service.

The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both traction control and StabiliTrak, press and hold the button for five seconds.

Traction control and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason.

When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate TCS off or StabiliTrak off message will be displayed on the DIC to warn the driver. Your vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system.

If the StabiliTrak and/or Traction Control are not operating properly, I encourage you to take your vehicle in for inspection. A certified technician will be able to offer a more accurate diagnosis.

Hi there:

Your vehicle is equipped with StabiliTrak, which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
Traction control activates when the controller senses wheel spin. StabiliTrak will selectively apply the brakes and reduce engine torque to help regain traction.


Stability control activates when the controller senses a discrepancy between your intended path and the direction the vehicle is travelling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help guide the vehicle in the direction which you are steering.


When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing.


When the StabiliTrak system is both on and actively controlling the stability of the vehicle, the StabiliTrak light will blink for the duration of the event.


You may also feel or hear the system working. This is normal.
StabiliTrak will turn off automatically if a problem is detected in the system. The StabiliTrak light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak service light) does not clear itself after restarting the vehicle, you should see your dealer for service.


Hope this helps.

Have it checked for DTC'S - diagnostic trouble code's.

{: ) A car swerving light on the instrument cluster is the StabiTrak indicator, sometimes called the traction control indicator. A wrench beside it tells it requires servicing.
