Usually because the car is burning too much fuel, or running rich. It can be caused by o2 sensors, throttle module problems, as well as other things. What i would do is to disconnect the battery for 5 minutes to clear the driving parameters. Then see if the problem goes away. I had a bad battery cause my parameters to get fudged up and after i replaced the battery the problem persisted.
The dealer told me bad o2 sensors but after i took it home and reset the batter for 5 minutes it was fine and never had the problem again.
