2022 Toyota Prius: what breaks, and at what mileage
What breaks on the 2022 Toyota Prius
On the 2022 Toyota Prius, the failure owners report most often is other engine problem, with 4 reports on file. Across every failure mode on this year, half the dated reports were filed before 35,000 miles. Overall it scores 75 out of 100, high risk for a 2022.
High risk for a 2022 — 117th riskiest of the 243 2022 vehicles we can rate. 31 owner reports; fleet size estimated from this year's own recall paperwork.
The failures owners actually file about
Owners have reported 18 named failure modes on the 2022 Toyota Prius, and the three most-reported carry 26% of everything filed, which is an unusually even spread for one model year.
Other engine problem leads with 4 reports and about 1.0 per 1,000 vehicles.
Airbag failed to deploy in a crash follows with 2 reports.
Other speed control problem follows with 2 reports, median 25,000 miles.
By system, the reports fall mostly into engine (7), adas (3) and airbag (2).
The mileage the reports cluster at
Too few of the reports on this year carry an odometer reading to describe the timing: 6 of them do. The mileages quoted elsewhere on this page come from the modes that have enough of them.

How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

How bad it is when it goes
Across the named modes, 5 mention a crash and 1 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 6.06, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other engine problem at $300–$4,000, airbag failed to deploy in a crash at $1,000–$5,000, other speed control problem at $250–$2,000 and other visibility problem at $150–$1,400. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
26% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2022 Toyota Prius draws about 7.4 per 1,000 vehicles, which puts it in the 89th percentile of complaint rates among 2022 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 4,205 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2022 vehicles, which is what the risk score uses, is far more robust than the rate itself.
Recalls on the 2022 model year
NHTSA has issued 1 recall campaign covering the 2022 Toyota Prius, affecting an estimated 4,205 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover hybrid propulsion system. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.
HYBRID PROPULSION SYSTEM
8,411 vehicles 2021-09-22- Defect
- Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2022 Prius and Prius Prime vehicles. The Engine Control Unit (ECU) software may falsely detect an error and shut down the hybrid system, causing a loss of drive power.
- Consequence
- A loss of drive power increases the risk of a crash.
- Remedy
- Dealers will update the ECU software, free of charge. Owner notification letters were mailed November 18, 2021. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 21TB07/21TA07.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
How it ranks in the 2022 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
Where 2022 sits in the model line
High risk for a 2022 — 117th riskiest of the 243 2022 vehicles we can rate. The comparison is always within the same model year, so an older car is never penalised for having had longer to break.
Across the 24 model years of this car that carry enough reports to score, 2004 comes out best at 66 and 2010 worst at 81, with 2022 itself at 75.
If the model year is negotiable, 2004, 2003, 2007, 2006, 2002, 2001, 2018, 2025, 2005, 2014, 2008, 2013 and 2011 score lower than 2022 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.
Within the 2022–2026 generation specifically, 2025 is the strongest year at 69 and 2024 the weakest at 77.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2022-2026 generation, 2025 Toyota Prius scores best at 69 and 2024 Toyota Prius worst at 77.
The limits of complaint data
31 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 31 reports, 6 carried an odometer reading, so the mileages here describe 19% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2022 Toyota Prius?
The most-reported failures are other engine problem (4 reports), airbag failed to deploy in a crash (2 reports) and other speed control problem (2 reports, median 25,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2022 Toyota Prius reliable?
It scores 75 out of 100 on our risk index, which is high — 117th riskiest of the 243 2022 vehicles we can rate. The score is a comparison against other 2022 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the Toyota Prius is best?
Within the 2022–2026 generation, 2025 scores best at 69 out of 100 and 2024 worst at 77. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
