2007 Toyota Prius fuel system problems

Filed Jan 15, 2026 · Fuel system · MD

2007 Toyota Prius touring edition WILL NOT TAKE ANY FUEL PROPERLY AND WILL OVERFILL AND "BURP" CAUSING GAS TO FLOW EXPLOSIVELY OUT OF THE FILLER NECK AND HOLE. Tank will not fill, at all, causing risk of running out of gas while on highway. FUEL GAUGE DOES NOT WORK AT ALL. FUEL TANK will not fill properly, if at all, overfills and burps causing fuel to blow out of the filler hole with force. THIS IS A FIRE HAZARD as gas can spill all over near the filler area and possibly catch fire. Stopping the filler hose will not help, as the tank refuses to take any gas, even when close to empty. People need to put gas in, not guess. The car will ONLY TAKE BARELY 2 gallons in winter without overflowing. THIS IS A LIFE SAFETY AND FIRE HAZARD AS THIS OVERFLOWING GAS AND REVERSE FUEL FLOW CAN IGNITE, or catch fire. THE BLADDER IN THE TANK STOPS WORKING AND WILL NOT ALLOW FUELING ANS SPITS FUEL BACK OUT OF THE FILLER NECK AND HOLE.

The contact owns a 2007 Toyota Prius. The contact stated that while at a stop light, she attempted to drive however, the vehicle failed to exceed 25 MPH. The HC battery, ECU, and check engine warning lights were illuminated. The vehicle was towed to an independent mechanic, who informed the contact that the vehicle displayed DTC code: P3190 (Engine Failure). The vehicle was towed to the local dealer, where it was diagnosed that the hybrid battery was severely drained, and the mechanic retrieved DTC codes: P3000 and P0A80 for the hybrid battery pack. The vehicle was not repaired. The vehicle was towed to another independent mechanic, who replaced the battery, but the failure persisted. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 160,000. The contact stated the vehicle was actually overfilled with oil at the mechanic's shop that performed the oil change, so that is what caused the issues with my vehicle.

Our daughter was driving our 2007 toyota prius to work in the dark in rush hour on the highway, driving straight, at highway speed, in los angeles, and the instrument panel instantly blacked out, with the car completely dead and halted. It could not even be shifted into neutral! The car stopped right in the middle of the highway. She called 911, and a wrecker was dispatched to lift the car off the freeway. Thankfully she was not injured or killed! I then researched the likely cause and diagnosed it exactly. It was the "hybrid water pump" also known as the "inverter pump," part #g9020-47031. That part was recalled in 2012, the federal safety agency recall # 12v536000. I had it towed to a nearby toyota dealer, north hollywood toyota, to have it repaired. That dealer looked up the vehicle's records and said the recall had been performed in 2013. Was it really? If so, then a recalled part that causes a complete, instant blackout on a prius already failed again. The receipt for the repair is attached, including the federal safety agency recalled part #. The repair cost $699.09 + tax, and caused an extremely dangerous instant stoppage of the vehicle on a jam-packed highway. I e-mailed toyota USA customer service to appeal the situation, and they sent me a reply and asked that I call them. On the call, they claimed there is no recourse for me to pursue. I'm a 51 year old u.s. Army officer veteran and have never experienced or known of anything this suspicious and dangerous in the automobile space.

The prius' charcoal canister has failed, triggering repeated "check engine" light warnings. This seems to be an issue prompting a recall of other 2007 priuses, like mine, but toyota says my vehicle isn't covered.

Fuel gauge not reading properly in car. Car label states 11.9 gallon capacity in fuel tank. Gas gauge shows one bar of gas left in car, but it takes only six gallons of gas to fill up automobile. This misleading gas gauge means drivers do not know what the true reading of gas is remaining in their fuel tanks which could lead to the car running out of fuel in the wrong place at the wrong time. This occurs when the car is moving.

I have owned two 2007 toyota prius. Both have been totaled due to what I believe is a failure of the hybrid drivetrain to disengage during emergency braking. This report is regarding the first vehicle. I have filed a separate report for the second vehicle which I still have in my possession. First 2007 prius, purchased new in 2007. On dec 9, 2009, to avoid a collision, I fully pressed the brakes with full force however the prius continued to propel forward. I should easily have been able to stop the vehicle in time. As it continued to propel forward, I collided with the other car. The speed at the moment of impact was approx 25 MPH. No airbags were deployed. The vehicle was deemed a total loss due to the extensive cost of repairing the hybrid system. I have the photographs of the accident and the police report. Second toyota prius: I purchased an exact replacement used 2007 prius in dec 2009. On october 17, 2015, a car stopped abruptly in front of my wife who was driving at approx 40 MPH. She reported pressing on the brakes with full force but that the prius continued to propel forward. She hit car in front then swerved to the right as the prius continued to propel forward. She steered to the left into the center median and the prius stopped. The car then caught on fire. No airbags were deployed. I have the photographs of the vehicle and the police report. I contacted toyota in nov 2015. An investigation was opened. A toyota 'field technical specialist' inspected the vehicle. I signed an 'edr consent form' for toyota to read any data from the vehicle. However due to the fire, they were not able to read any data. On january 26, 2016 I received a letter from a legal claims administrator at toyota motor sales, USA, inc., stating 'our inspection was unable to confirm any evidence of a manufacturing or design defect in your vehicle'.

Vehicle only has 110k miles on it. Check engine starting going on when accelerating on uphill. Full up gas tank & light would go off. Then check engine would go on when low gas level. Told to change gascap. Did not resolve issue. Filling pulled codes it was catalytic converter. Part cost $1700.00 for part alone for a part that is suppose to last lifetime of car.

I'm the original owner and do my own regular oil changes at the manufacture specified intervals of 5000 miles. This last time I noticed not much oil coming out of the drain pan, poured it back into an empty oil jug to measure and yes only 1.5 quarts drained out. I haven't seen any smoke or smelled any oil burning and no obvious leaks. I don't run the engine hard or at high speeds (less than half my driving is interstate) but can't figure out why it's all of a sudden started using oil. When I searched online it seems to be a common failure with prius over 100k miles. I want to add my other toyota and honda vehicles have lasted well over 200k and 180k miles with no engine troubles at all (I also do the maintenance on them)
