What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 5,726 complaints with NHTSA about the 2010–2015 Toyota Prius, and 3,988 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
49% of failures fall within the first 12,000 miles — a rate roughly 11 times higher than during the rest of the car's life. Failures clustered that early usually indicate a design or manufacturing problem rather than wear.
The most-reported areas are the brakes (25.1% of complaints, typically around 87,000 miles), the hydraulic brake circuit (16.3% of complaints, typically around 3,500 miles), the electronic brake control (8.8% of complaints, typically around 3,000 miles).
12 recall campaigns cover this generation.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 15,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The brakes account for 25.1% of complaints (1,435 reports, 661 of them with a mileage figure), and they fail late — a median of 87,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 34,000 and 128,000 miles.
A single system taking 25.1% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The hydraulic brake circuit accounts for 16.3% of complaints (935 reports, 823 of them with a mileage figure), and it fails early — a median of 3,500 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 1,000 and 7,500 miles.
The electronic brake control accounts for 8.8% of complaints (502 reports, 445 of them with a mileage figure), and it fails early — a median of 3,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 1,000 and 5,600 miles.
The electrical system accounts for 7.4% of complaints (425 reports, 283 of them with a mileage figure), and it fails late — a median of 58,847 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 13,000 and 113,000 miles.
Throttle and speed control accounts for 6.5% of complaints (370 reports, 305 of them with a mileage figure), and it fails early — a median of 5,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 1,400 and 18,000 miles.
The engine accounts for 4.9% of complaints (279 reports, 211 of them with a mileage figure), and it fails late — a median of 98,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 63,000 and 133,883 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2010 model year drew the most — 3,483 complaints — while 2015 drew the fewest at 213. The median year sits at 542.
That makes 2010 an outlier: roughly 6.4 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.
Recalls and what they cover
NHTSA records 12 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
The campaigns cluster around the hybrid propulsion system (3), seats (3), equipment (3). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
Of the 5,726 complaints filed against this generation, 542 reported a crash; 45 reported a fire; 280 reported an injury; 5 reported a fatality. Crash-involved reports represent 9.5% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, an early-failure pattern is comparatively good news on a used example: 48% of the reported failures occur in the first 12,000 miles, which on a car of this age means they have already happened or they were never going to. Service history matters more than mileage here.
On inspection, the brakes and the hydraulic brake circuit are where this generation's reports concentrate, so those are the areas worth a specific look. The hydraulic brake circuit in particular shows a median failure mileage of 3,500, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
Documented problems
Egr System / Head Gasket 2010–2015 (most reported on 2010–2014)
The EGR cooler and intake-side EGR passages accumulate heavy carbon deposits, restricting flow and driving localized combustion heat that fails the head gasket between cylinders. Symptoms are cold-start misfire (P0300/P0301), coolant loss with no external leak, and rhythmic shake on startup. The EGR cooler itself can also leak coolant internally, producing near-identical symptoms at far lower repair cost. This is the defining failure mode of the generation.
Engine (oil Consumption) 2010–2014
Excessive oil consumption on the 2ZR-FXE traced to piston ring design, commonly one quart per 1,000-2,000 miles, which accelerates the EGR carbon fouling above.
Brakes 2010
ABS and regenerative braking handoff software could produce a momentary loss of braking response over bumpy or slick surfaces; the subject of Toyota's February 2010 recall, one of the highest-profile Prius actions.
Inverter 2010–2014
Inverter IGBT control software could allow the hybrid system to shut down while driving; covered by a 2014 Toyota recall spanning the generation.
Water Pump 2010–2015
Electric coolant pump failure causing overheating and hybrid system warnings.

What owners reported
When carefully braking my 2010 Toyota Prius at low speeds (40 MPH and lower), a small dip or bump in the road will cause the car to release the brakes and the effect is a sudden acceleration or release of the braking system which lasts approximately 1 second. This failure in the vehicle is seemingly unrelated to a…
2010 · Electronic brake control
01/13/2010 - I went to the service dept at Toyota of wallingford to complain about the loss of brakes in a new 2010 Toyota Prius while driving over uneven ground. I had owned the car one month with 1500 miles on the odometer. The loss of control of the car is terrifying because the car seems to accelerate forward. The…
2010 · Hydraulic brake circuit
I have a 2010 Prius and had a 2005 Prius with all the safety features. When i had the 2005 Prius, i noticed on some roads that during braking, the brakes would release then reengage, giving the sensation that the car is accelerating. This happens when the road has a series of dips (washboard). The first couple times…

My 2010 Toyota Prius drifts when i'm trying to drive the car straight. The car is very difficult to maintain a straight ahead position. I have to constantly be turning the steering wheel left then right, especially while driving at highway speeds. The car drifts both to the left and right. It won't go straight for…
