The power steering system may fail due to a faulty electrical ground to the power steering control module (PSCM). Dealers will clean paint from behind the ground stud nut and update the PSCM software free of charge to correct the problem.
General Motors notified owners of affected vehicles starting in July 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The General Motors recall number is 14330.
Suspension & Steering
If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
