Fuel indicator on the dash showed 3 bars for remaining fuel. Vehicle ran out of fuel despite showing 3 bars. Oftentimes after tank is filled it only illuminates to 1 or 2 under the top bar instead of showing a full tank. There is obviously a problem that the car is not accurately reporting the fuel level.

Hybrid engine suddenly shut down without warning while vehicle was traveling 65 mph on a busy freeway, causing vehicle to come an unsafe stop. Depressing accelerator had no effect. Onboard computer gave error message "check hybrid system. Stop the vehicle in a safe place." Restarting vehicle produced the same error message and still unable to shift vehicle into drive or reverse. Fuel tank full at time of incident. Vehicle purchased new 5 months prior from Toyota dealership. No aftermarket parts or modifications present.

When driving dashboard "hybrid system not working. Pull over..." this was 7/3/2012. It had run out of gas even though there were 2 bars out of 10 still present on gas gauge. On 7/30/12 later this happened again with 4 bars showing. Got the fuel sensor and gauge replaced on 7/30/12. 8/14/12 with 3 bars showing, cruising range of 60 miles and having gone 480 miles the same warning "hybrid system not working..." I was able to get to a gas station before running out of gas. The Prius manual states the tank holds 9.5 gallons. Filling up the tank took 9.91 gallons. There is clearly something wrong. The fuel sensor and gauge have already been replaced, though. This is a major problem for a new car. This is a new model.
