Condition Certain 2017 model year Buick LaCrosse vehicles may have a condition in which the inner front-of-dash seal for the steering shaft may not be properly installed. If this condition is present water could

steering shafts. This corrosion could damage the pinion seal, allowing water to reach the torque sensor.
Correction Inspect the inner intermediate steering shaft boot, and replace if necessary
