Loss of power steering (in one direction only) at low speeds. Affects ability to park vehicle in tight spots and to make slow turns. Have managed to avoid a accident. This has been an issue for over a year and over the last 15,000 miles. Three different mechanics gave various possible reasons but no one, including the gm service line, could give a definite cure. Was told "could try" power steering pump, steering box, etc. All were costly solutions with no guarantee of cure.
