Power steering control module failure

I have seen similar threads on this topic, but am having trouble believing my dealership's diagnosis. While driving my 2011 Volt home recently on a two lane highway, my power steering went out and I got the "Service Power Steering" message on the dash. While difficult to steer, I continued home (about 15 miles). I charged the car overnight and called the dealer in the morning. When I drove to the dealer, the steering worked fine, but I still wanted the dealer to check things out.

After several days of trying to diagnose the problem, they determined the steering gear mechanism was not getting power due to an intermittent failure in the control module. Their plan is to replace the control module.

When I mentioned there was a bulletin extending the warranty on the power steering to 10 years, their response was that was for the gear/motor mechanism, not for the control module. So whenever they get this done, I will be paying the full amount. Seems to me, and from what I've read on this forum, the mechanical and electrical pieces are interrelated, and all of it should be covered by the 10 year warranty.

Is the dealer correct? Or should I push back?

This is what the special policy is for on the power steering:

Note: The calibration for the Chevrolet Volt will not be available until November 26, 2014.

Some 2012-2014 model year (MY) Buick Verano, 2011-2014 MY Chevrolet Cruze and Volt, 2010-2014 MY Chevrolet Equinox and GMC Terrain, and 2013-2014 MY Chevrolet Malibu vehicles may have increased friction in the steering system. This could cause the steering wheel to stick in the straight-ahead position after driving long distances on a straight highway. The steering wheel can be turned but it may require increased effort.

Special Coverage Adjustment
This special coverage covers the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers are to 1) replace the steering gear on 2010-2012 model year vehicles; or 2) reprogram the power steering control module on 2013-2014 model year vehicles. The repairs will be made at no charge to the customer.

If the failure is not due to the sticking steering, the warranty does not apply.
