Will a dealership reflash the ecm of you ask? Ever since they did the cvt update on my 17 spark the transmission has been shifting funny sometimes and worse gas mileage.

No if the update was to fix a recall or drive ability issue. But if enough people complain they will look at it and possibly issue a new update. Thats what happened on my 2014. They updated the CVT which caused the steel belt to slip in certain conditions and cause a terrible vibration. They then sent out a recall notice for another update to fix that issue since the slippage could cause excessive wear on the belt.
