After reading in my instructions Manuel about what might be causing my fuel consumption to be way to high I learned that the gas cap was suppose to click which it has not since we got the vehicle in December of 2021so I went and bought a gas cap and now it clicks like it's suppose to. My fuel consumption is way to high right now I have filled this car up with gas so many more times then any other vehicle I have owned. When I put fuel in you can smell the fuel for the next two days and every now and again you get a whiff of engine coolant smell and a burning smell I'm not sure what the burning smell is because I've never smelled it before. Yes the vehicle is available for inspection. No one has inspected it still since my last complaint. And no there has been not a single warning light.
