Power Steering Failed problems of the 2012 Chevrolet Equinox

When in-motion at my power steering fails, the wheel seems to grab and my control of the vehicle is momentarily not in my control. It happens on straight aways and most often in slow speed turns. My concerns are the incidents that might happens in busy traffic and on wet & iced roadways. This has been happening in the last 1000plus miles and my service power steering notice has flashed at least 2 times. I am scheduled for service today.

On 3/31/15, chevy dealer that sold us the car replaced the steering gear subject to bulletin 14232, because we got a letter from gm advising us to get it done. On 10/17/16, power steering failed during a turn on city street, causing emergency braking and near miss. The power steering froze up, and the wheel would not turn. This happened near the end of a 10-mile commute. On 10/18/16, this scenario was repeated near the end of a 10-mile commute. The car was towed at this time to the same dealer. On 10/25/16, dealer returned car to us un-repaired, saying they could not duplicate the problem, the car is out of warranty, and that the problem is a new one. They offered to repair the car for $400. We told the dealer this is a known problem, that they replaced the steering gear that is currently failing, and that there is a ten year non-warranty window on this type of safety repair. On 10/26/16 we called Chevrolet customer service to complain. They got back to us on 10/27/16 and offered to fix the car for $400. This is a dangerous if intermittent problem that is known to gm, and they are obliged to fix it. There is at least one other case (NHTSA id #10689932) of steering failing after steering gear replacement pursuant to bulletin 14232.
