2010 Toyota Prius Complaints: What Owners Actually Filed
Owners of the 2010 Toyota Prius filed 2,819 complaints with NHTSA; the service brakes, hydraulic leads with 27% of them, ahead of the service brakes at 21%. That's a count of reports, not a rate: a model that sold in large numbers files more complaints than a rare one with a worse record, and nothing in the file knows how many were sold. Use it to decide what to inspect before buying, not to grade the car.
The 2010 Toyota Prius problems owners filed, by system
| System | Complaints | Share |
|---|---|---|
| Service brakes, hydraulic | 751 | 27% |
| Service brakes | 590 | 21% |
| Service brakes, electric | 502 | 18% |
| Vehicle speed control | 286 | 10% |
| Electrical system | 183 | 6% |
| Exterior lighting | 145 | 5% |
Vehicles with fewer than 10 complaints aren't in the file at all, so a system missing from this table drew fewer reports than the ones shown, not none.
Is it this year, or the model line?
No other model year of the Toyota Prius has the service brakes, hydraulic named most. Whatever this is, it's not the whole model line.
The whole Toyota picture, every system by model year, is on the Toyota brand page.
Recalls to check before you buy
The one part of this page that is a verdict rather than a count: recall campaigns are the manufacturer's own admission, filed with the regulator. The list is by model year, not by car; whether a particular car had the work done is in the dealer's records, or in NHTSA's VIN lookup through our decoder.

What this page doesn't know
How many were sold. The file counts reports, not cars, so a popular model looks worse than a rare one with the same problem.
Whether your car has it. A share of complaints isn't a probability for one vehicle. It says which system to have inspected, and which service records to ask for.
Who filed. Filing is voluntary, and a recall or a news story sends owners to the form in numbers a quiet year never sees.
What it costs to fix. Nothing on this page is a repair price. The site's cost articles are censused on specific cars, not on this file.
