When other fuel system problem gets reported

Owners of the 2010 Toyota Prius report other fuel system problem at a median of 82,500 miles. A quarter of the reports come in before 37,500 miles and a quarter after 137,500 miles, from 32 reports that carried an odometer reading.

A part like this is normally expected to survive 90,000 miles. It is the 14th most-reported problem on this model year.

The mileage distribution

The reported range runs from 10,000 miles at the tenth percentile to 167,500 miles at the ninetieth, a spread of 158,370 miles across the middle 80% of reports.

When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.

19% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 32 odometer readings owners gave.

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

Of these reports, 1 a crash and 1 a fire are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.

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 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.

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.

2010 toyota prius - when braking, if you hit a bump or pot hole in the road, the car lunges forward (accelerates). You have to really pay attention for this occurrence or you will rear end someone. I has happen about 5 times now. This seems to be a electronics issue not a pedal problem. *tr

10,300 miles NHTSA complaint 756345 filed 2010-02-03

I own a 2010 toyota prius, 3rd generation. When I am braking and hit a pothole or a manhole cover, the car surges forward. I took it to the dealership today and they checked the car and said they couldn't find anything wrong with it. They also said they had no knowledge of any kind of braking or surging problems with this vehicle. Our dealer was eastern shore toyota in daphne, al. This has happened approximately 6 different times since we bought the car in 2009. It started to occur approximately in july 2009, with the most recent episode in january 2010. *tr

3,000 miles NHTSA complaint 757116 filed 2010-02-03

I own a 2010 prius. After putting 10k miles on it, I have yet to see the 50+ mpg. I could have easily bought a honda civic, saved $15,000+ and still gotten 38mpg. I have taken the car to the dealership on a few occasions and they cannot tell me why I have lost almost 20mpg. All they can tell me is that it is probably the gas that I am using. I can see how this might make a slight difference like 3-4mpg, but not 20! I believe the 50mpg benchmark given by toyota is bogus. I want my money back! *tr

How far this goes

Complaints are voluntary, so 43 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 2010 Toyota Prius?

Across 32 owner reports that included an odometer reading, half were filed by 82,500 miles. A quarter were filed before 37,500 miles and a quarter after 137,500 miles. 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 2010 Toyota Prius?

43 reports have been filed with NHTSA, about 0.3 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.
