Other fuel system problem on the 2017 Toyota Prius
Only 4 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other fuel system problem gets reported
There are 5 reports of other fuel system problem on the 2017 Toyota Prius, 4 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 90,000 miles. It is the 11th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 15,970 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $300–$2,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 14 model years of this car. It shows up earliest on the 2009, at a median of 10,000 miles, and latest on the 2011 at 115,000 miles.
By volume the 2010 carries the most reports, with 43; the 2017 has 5. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
On I-75 @70 miles/hr, with around 800 mileage new prius, toyo tire of the rear tire popped out and rolled on the I-75 without any warning lights but with some gas smell, putting all the occupants to high risk of crash on the busiest freeway, and the agony of the incident. I towed my prius to valdosta toyota, even though toyota care should cover roadside assistance, they charged me for towing and putting new tire. There was a problem with the prius gas system or toyo tire of prius. After around 100 miles I tried to put in gas, prius tank didn't take gas, went to clear water toyota and got it repaired, despite explaining toyota care and less than 1k mileage, they charged me for repair. Contacted toyota care and my local dealer, they said valdosta and clear water toyota should not have charged. The dealers say toyota care need to reimburse the repairs at least, as they can't compensate the agony of losing a tire in the middle of the freeway. Toyota care doesn't even bother to register a complaint and investigate the issue and determine prius gas system or toyo tire is under fault. Even after going through 3 toyota dealers and…
The vehicle started normally but when I reached about two blocks from my house, the prius started to act as if the electric motors were not engaging. The engine did not engage either and the gas pedal was unresponsive. The first time this occurred, I was stuck in the middle of a 4-way intersection until I shut down the vehicle and restarted it. After I restarted the prius, it continued behaving erratically. It sounded and felt like the gas motor had engaged but the electric motor had not. It also felt like the transmission was slipping/not engaging and I had to rev the motor to get the transmission to engage (which it did with a kick like it was being put into gear). This has happened 3 times so far. I had a passenger in the vehicle on the last incident. I have taken the vehicle into the dealership 3 times, but they are unable to find any issues with the vehicle. I reached out to toyota to see if they could address the issue, but they said that their field tech was unable to find any problem. I am worried that this car will fail in traffic and cause an accident. The incident dates are june 20, july 2 and july 27, 2018. The only…

How far this goes
This page is kept out of search results because 5 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 5 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other fuel system problem happen on the 2017 Toyota Prius?
Across 4 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other fuel system problem on the 2017 Toyota Prius?
5 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
