15-NA-015: Unwanted Steering Pull or Drift – 2012-2017 Buick Chevrolet

Buick Encore 2013 2017 All All
Chevrolet Sonic 2012 2017 All All
Chevrolet Trax 2013 2017 All All
Involved Region or Country North America and N.A. Export Regions
Condition Some customers may comment on a steering drift or pull condition where the vehicle may appear to pull or drift in the direction of a road crown.
Cause This may be caused by the power steering control module.

The power steering control module has advanced software features referred to as Active Pull Compensation.

Active Pull Compensation constantly measures steering wheel torque being applied by the driver to maintain the vehicle’s path. When the software detects extra effort being used to maintain a straight path, the steering assist motor adds torque in the proper direction to prevent the driver from having to make corrections to keep the vehicle on course. The torque assistance reduces driver fatigue and effort and makes steering easier. The software automatically resets itself to compensate for changing road conditions or the vehicle turning on curves. This software feature will compensate for a specific range of drift pull up to its maximum limit within a set of parameters. It must be understood that a drift pull, in the direction of road crown is normal vehicle behavior when Active Pull Compensation is not active.

  • The power steering control module uses the steering shaft torque sensor as its main input for determining steering direction, which is why hand pressure on the steering wheel must be maintained at all times.
  • If the vehicle is allowed to drift to a point where a large correction (steering angle input) is needed, the Active Pull Compensation will interpret this as a turn and will not learn this as a changing road condition.
  • Without hand pressure on the steering wheel, the system cannot determine the amount of assist that is needed to maintain the vehicle on a straight path.
  • The Active Pull Compensation is not intended to reduce driver effort when travelling on a curved section of road.
  • The Active Pull Compensation function only becomes fully active above 37 mph (60 km/h).
