How to read this file. Complaint records are unverified owner submissions to the federal safety agency. Counts are raw, not adjusted for sales volume or vehicle age. Recall campaigns apply to the model; only a VIN check shows whether this car is affected or repaired. Parts shown are named by an editorial note or listed as a search directory; none is a diagnosis. Full methodology.
Fault profile
Complaint-component records on this vehicle, grouped by family. A complaint naming two systems counts once in each.
Complaints are owner-reported and not verified by the agency.
When it fails
The timing of this vehicle's reported failures, from the complaint file itself. A cluster tells you what to expect and when; it is shaped by reporting behavior as well as by the vehicle.
Vehicle age when the failure occurred
Years between the model year and the owner's reported failure date. Based on 97 of 99 complaints with a usable failure date.
Odometer when the failure occurred
Owner-reported mileage at failure, in 20,000-mile bands. Based on 75 of 99 complaints reporting a plausible odometer (500 to 500,000 miles; unverified).
Known issues
The component families with the most complaint records against this vehicle. Counts, crash and fire figures belong to the whole family, not to any single named issue. Parts listed are related system parts, not a diagnosis.

Federal defect investigations
Formal investigations opened by the federal safety agency into this vehicle. An investigation is the step between a complaint pattern and a recall; not every one results in one.
| Investigation | Status | Component | Subject |
|---|---|---|---|
| DP22005 opened Jan 2023 | closed Aug 2023 | Electrical System | Pedestrian alert sounds - led to recall 22V063000 NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. |
Recall campaigns
Safety-recall remedies are normally provided at no charge. Under US federal law the mandatory free remedy applies when the vehicle was no more than 15 years old at the time the defect was determined; manufacturers often cover older vehicles voluntarily. Canadian rules differ. Confirm eligibility with the manufacturer using the VIN. Each campaign number links to the federal record.
| Campaign | Component | Summary | Remedy |
|---|---|---|---|
| 11V304000 | Steering | TOYOTA IS RECALLING CERTAIN MODEL YEAR 2001 THROUGH 2003 PRIUS PASSENGER CARS MANUFACTURED FROM JANUARY 28, 2000, THROUGH MAY 30, 2003. | Normally free |
Transport Canada recalls
Recalls issued under Canadian law for this model year, from Transport Canada's Vehicle Recalls Database. Matched by model name, so a Canadian-market variant may appear here that was sold under another name in the US. Units are Canadian vehicles affected.
| Recall | System | Units (CA) | Summary |
|---|---|---|---|
| 2011212 2011-06-01 | Steering | 940 | On certain vehicles, the nuts which secure the pinion shaft inside the steering gear box may not have received adequate tightening torque during the assembly process. |
Service bulletins and warranty extensions
Manufacturer communications to dealers on file with the federal agency: repair instructions, service campaigns, and warranty extensions. A warranty extension means the manufacturer may pay for a repair the recall table does not cover.

Before you buy this vehicle
A test-drive checklist generated from this vehicle's own complaint and recall record.
- Drive one straight highway stretch and one slow parking lot.Wander or a shimmy over bumps at speed, and heavy or dropped assist at low speed, are the two faces of this vehicle's steering cluster. A clunk on turn-in points at the linkage.
- Brake hard once from speed on an empty road.A pull to one side, a pulsing pedal, a pedal that sinks at a stop, or an ABS light that stays lit are the brake complaints on this vehicle presenting themselves.
- Sit in it with the engine off and test everything that has a switch.Windows, locks, lights, the cluster, the radio. Electrical faults are this vehicle's story and the hardest to see on a drive: an intermittent no-start waits for the second week of ownership. Ask for the battery's age and whether any control module has been replaced.
- Run the VIN against open recalls before you negotiate.This vehicle has 1 recall campaign on file. An open recall needs VIN-specific confirmation. Many are quick, no-charge fixes and worth negotiating over; an unresolved do-not-drive advisory, or a remedy the manufacturer has not yet made available, should stop the purchase until it is resolved.
- Ask for the service history in writing, then read it against this page.The complaint families above are where owners of this vehicle report trouble. Repairs in exactly those systems are evidence the car had the problem; no such repairs could mean it never developed it, or that it was never fixed. The test-drive items above are how you tell those apart.
Parts search directory
The generic parts list for this vehicle has its own page: a search launcher for every system, filtered by fuel type and era but not by engine, trim, or brake type. It is not a diagnosis and not a fitment guarantee.
