2010 Toyota Prius — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 3,485 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Brakes2,022 (58.0%)Official recall records for this system: 9, covering model years 2010–2019.
• Speed control & accelerator287 (8.2%)Official recall records for this system: 1, covering model years 2004–2009.

• Stability & traction control98 (2.8%)Official recall records for this system: 1, covering model years 2019.

Other / uncategorized: 108 classifications (3.1%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

• Owner complaints (24,976 records, model years 2001–2026) are most frequently classified under: brakes, lights and electrical system.
• Safety recalls (126 records, model years 2001–2026) are most frequently classified under: high-voltage battery & electric drive, air bags (restraint system) and equipment & accessories.
• Transport Canada recalls (121 records, model years 2001–2026) are most frequently classified under: electrical system, powertrain (transmission & drivetrain) and brakes.
• Manufacturer communications (7,014 records, model years 2001–2026) are most frequently classified under: equipment & accessories, electrical system and engine.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records

Mileage reported when the issue occurred

• 2,280reports included a mileage
• 41,419average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.

• P0A94 in 7 records
• P0A7A in 2 records
• P0401 in 1 record
