[BOOST26]

I had this same problem in my 2010 G6ET. Dealer changed the buttons and problem came back.
In the end I thought maybe they hadnt changed the buttons so I thought I would mark the buttons before I took it back for warranty replacement.
When I pulled the Steering wheel airbag assembly off I noticed the wiring to the buttons was just running freely across the steering wheel. I tucked it into the locating clips and put it back together.
Havent had a problem since (touch wood) and that was nearly 12 months ago??
