This bulletin applies to 2014-2015 Buick Regal, LaCrosse and Verano vehicles equipped with non-variable ratio electric power steering. Some customers may comment on a sticky or notchy feeling in the steering wheel, near the center position, after a duration of time on the highway while making lane changes.
The condition may be due to increased effort required to overcome residual friction after driving for long periods with no steering input.
According to GM, reprogram the power steering control module according to “Power Steering Control Module Programming and Setup” in the service manual.
