There is a problem with the 2010, and similar years. When you fill up with gas and the pump clicks off the first time, do not force feed the gas into the tank. What happens if raw gas is forced into the evap canister, which can destroy it, and damage the evap valve and solenoid. The 2010 will automatically run a self diagnosis while you are driving and try to pull a vacuum on the fuel tank. If the valve is damaged and it continues to try to pull a vacuum, it will. The result is the gas tank collapses inward. You may also see the engine randomly just kill while driving. Proper diagnosis of the EVAP system requires test equipment not readily available to car owners. I suggest you have it checked by a qualified service department for the cause. A new fuel tank is about 900 bucks. The evap canister is a couple of hundred. The EVAP solenoid and vales is less expensive. This may be a situation where biting the bullet and bringing it to a shop if worth the cost. NOTE: If it happens to be something as simple as an O2 sensor remember. When the gas pump clicks off, it's full. Don't try to squeeze another quart into the tank.
