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.
Driving on highway and had 1/4 tank of fuel left when low fuel warning beep sounded. Fuel gauge was suddenly at "e" and display said 0 miles until empty. Immediately pulled into a gas station. Gas pump shut off after filling only 14. 5 gallons, although tank capacity is 18. 6 gallons.
