What owners wrote

The check engine light has come on 4 times in the past year. The error code relates to the capless fuel system. The dealer has reset the code and replaced a fueling tube. On 7/24/10, engine light lit and five minutes later the engine cut out while driving less than 20 MPH. Car restarted without issue. It is currently being serviced.

Reported at 10,000 miles, July 2010

The fuel gauge will read between 1/2 and 1/4 tank then immediately make a *ding* and the display reads 0 miles. The fuel gauge will drop to empty. If you drive anything further than a short distance (10 miles or so) the car will die. It is "out" of fuel. Refilling the tank you will find that the vehicle still has whatever fuel the gauge was showing before it dropped to zero. It is consistent, it does this every tank. Appears to be getting worse as time goes on.
