      Water in the gas tank. 2019 XC90 t6 Inscription

      Filled up 3/4 of a tank. The check engine light came on on the way home but car was running fine. The next morning it would start, running for a second then shut off. Had it flatbedded to the dealer. Found out tank was full of water/ethanol. Apparently when enough water mixes with e10 gas the ethenol separates from the gas. (See the pictures.). Est to fix about $3,600. They are changing injectors, and fuel pump. They said they have never seen this much water in a tank before. I wasn't sure it needed all that but they told me if the injectors weren't replaced and failed down the road it wouldn't be covered because of the bad gas. Insurance is covering it and going after the station.

      Has anyone had this happen in a newer MY and what did they fix/replace?

      Wow. I remember a few years ago, the state of New Jersey charged a couple of gas stations with messing with their gas. Don't remember exact details though.

      Should also report it to the State Attorney General office. I would think most states have inspectors for this.

      The station called it phase separation. The ethanol bonds with the water and not the gas. They were doing some work on the tanks (black plastic on the ground with cones around it so I am guessing thats where the water came from.
