I have the same issue with mine. Currently and the dealer with just under 11,000 KM. They told me it's not safe to drive and the parts are on national back order with no estimate....could be one week or two months. All I can say it's a good thing it's not camping season! I live in Canada and will be filing a complaint with Transport Canada. This is total BS in my opinion...GM should step up, at least have parts available for replacement! Seems like lots of people having issues.
