Tank Assembly problems of the 2009 Toyota Prius

The contact owns a 2009 Toyota Prius. The contact stated that the fuel gauge would provide inaccurate readings of fuel levels. While driving 25 mph, the vehicle completely shut down without warning due to a bladder fuel tank problem. The vehicle was towed to the dealer who replaced the bladder fuel tank under warranty. The manufacturer was contacted who offered no assistance. The failure mileage was 43,000.

2009 Toyota Prius, car has had a bad fuel gauge , drove off the lot new and have had fuel tank replaced once. Fuel gauge failed again this is the second time. Dealer unable to repair, told me it was a design flaw and it could not be repaired, I am running out of gas and I can not use this new car on a long trip. I do not know and I am guessing on how much fuel I have. This is unsafe and uncalled for. Running out of glass on freeway and it is dangerous.

While driving a 2009 Toyota Prius at 50-55 mph on a single lane highway outside of prescott az, the drive system suddenly shut down and no response was felt when depressing the accelerator pedal. Lots of indicators came on and my wife was able to steer the car to the side of the road where there was just sufficient room for following traffic to go past. After spending a few minutes going through the owner's manual and finding no easy answer to explain this condition, we tried and were able to re-start the car. It must be noted that the fuel gauge when recently checked had indicated slightly less than 1/4 full and that we were proceeding up hill when the event happened. No add fuel indicator light nor low fuel alarm had occurred prior to this event. When the car was restarted it was on a more level but not flat surface. We proceeded on our travel with the flashers on and at a speed no higher than 30-35 mph. Soon thereafter we did observe both an add fuel indicator light and then a flashing light on the fuel gauge itself. We stopped at the nearest gas station and added fuel. The next day we took the car in to the Toyota dealer to have them look at the fuel gauge and electronically recorded history. The report showed that the car responded to an empty fuel tank by shutting if the engine and then the battery drive when its charge went too low (to protect the battery). We were told the this car has a bladder type fuel storage device and that it can act funny when it gets low. The car was checked out fine and returned to us with the words no wisdom to not let the car get too low on fuel. My concern is that the engine and drive systems shut down under high speed driving conditions without any low fuel warning indicators being activated.

Fuel bladder seems to have collapsed. When I am showing 1/4 tank left I can only put 6 gallons in the tank.

I own a Toyota Prius. On June 22, the fuel gauge started to act up. I took it to the dealership after having my car for almost 2 weeks they claimed it was fixed. They replaced almost everything to do with the fuel. I then took it back less than a month later with the same problem. They told me there was nothing they could do and just to never let my tank go below 1/4. To me, this is a danger. I never know how much gas is in my gas tank or when I may run out of gas. I then took it to another dealership and they explained to me this is a problem with the Prius, yet Toyota does nothing to fix this. Every few days I have to stop and get gas because my gas gauge does not work properly. I am driving around an accident waiting to happen.

Collapse of fuel bladder cause the Prius to run out of fuel with 2 gallons of gas in the vehicle while on freeway. Caused towing to dealership. When fuel was added to car only 8. 9 gallons could be added to a reported 10. 9 gallon tank capacity.

Fuel tank capacity dangerously variable in Toyota Prius. Our 2009 Prius routinely is unable to fill to full capacity of 11. 9 gallons. Worse is cold temperatures. Was not told of this issue at time of purchase. Have since learned more about the fuel bladder from consumer chat forums, but Toyota needs to disclose the range of fuel capacity in their manuals, or improve the design to.

Unable to properly fill the fuel tank. The fuel bladder collapses.

Prius bladder tank is a bad and flawed design leaving the consumer with inaccurate tank and mileage readings.
