I have 6000 miles and gas was used maybe 1500 miles. I searched online already. Everyone talks about how it is break in and its normal. I am like WTF. There is clearly a plastic burning smell coming from the car when the engine is warmed up. The car's been very good, but this problem along with some small flaws drive me nuts. My Smart car doesn't have the same features, but at least I know it doesn't stink when I get in it.
