Three problems related to other fuel system tank assembly have been reported for the 2012 Toyota Prius. The most recently reported issues are listed below.
Problem with the fuel bladder causing the gauge to read incorrectly. The gauge gets stuck at a quarter tank and before you know it, you're out of gas. Once this happened, it caused the hybrid system to fail and locked the car up even after putting gas in it. Has to do a master reset of the entire car to get it to start again.
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. ## VIN passed ## Toyota plugin Prius 2012 ##.
