You might need to get your gas checked for how much alcohol is in your gas. I had the light come on, took to dealer, they tested gas and it had 16% alcohol. Don't know where my wife got gas but you need to look for signs saying they don't use more then 10% enthanal. Dealer reset the light/computer and now we make sure we only get gas at a select few locations. We are also using 91 oct or higher, dealer said we didn't have to when we were looking to buy but now we know. $130/hr labor to test and reset computer, bad gas is not under warranty.
