Kestrel Take

The last year of the fourth-generation Prius, with twenty-four complaints and one recall — a software fault that can shut the hybrid system down and leave you without drive, fixed with a free ECU update in late 2021. Confirm it first. The rest of the record is small and oddly useful for a used buyer: two of the seven electrical complaints are odometer fraud discovered after a private sale — a car advertised at 30,000 miles that turned out to have 173,000 — which is a reason to match the mileage against Toyota's own service records before you hand over a cent. Around that, a brake booster that failed at 12,500 miles and stranded the car, a screech from the speakers at startup traced to the telematics unit, a hot spot on the steering wheel, and three airbag non-deployment reports a buyer cannot inspect for. Twenty-four filings cannot rate a car; they can tell you what to verify. Do the VIN lookup, do the mileage check, listen at startup, and buy on the remaining hybrid warranty.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 24 owner complaints for the 2022 Toyota Prius, and 1 recall campaign.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is electrics and electronics at 29%. That is notable without being overwhelming — worth checking, not worth panicking about.

One recall campaign covers this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Looked at and set aside: airbags (3) — Three airbag complaints, all three crashes with no deployment: a head-on into a fence at parking speed in a rental car, a one-word 'Brake' filing, and a total-loss crash in which the SOS call also failed. Whether an airbag should have fired depends on the crash, a buyer cannot inspect for it, and the same report sits on every year of every car we have read. There is no airbag recall on the 2022 Prius.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2022 Toyota Prius

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

ECU software can falsely shut the hybrid system down — loss of drive (recall)High — wallet impact

Recall 21V734 covers 2022 Prius and Prius Prime: the engine control unit's software can wrongly detect a fault and shut the hybrid system down, and a Prius with its hybrid system off is a car coasting to a stop wherever it happens to be. The remedy is an ECU software update, free; owner letters went out November 18, 2021, so most cars had it done at their first dealer visit. Nobody in this record has filed a shutdown we can read, which is what you would hope from a recall caught within months of launch — but the consequence is a loss of drive at speed, so it is the first line to check on the NHTSA VIN lookup. A car serviced anywhere but a Toyota dealer since new is the one to check twice.

Repair cost: $0 with the recall — verify it was performed

Brake booster failure at low mileage — warning lights, a grinding noise, then a car that will not moveMedium

Five brake complaints, two of them crashes. The one with a diagnosis is the expensive one: a 2022 at 12,500 miles lit up with warning lights, made a grinding noise and lost the ability to move — still powered on, unable to drive, towed to the dealer, who found a failed brake booster. On this generation the booster and master cylinder are one electronic assembly, the same part behind the 'Braking Power Low' complaints on the 2016 page. Another owner had the pedal go stiff and need a shove, repeatedly, and the dealer found the pedal and its bracket bent. Both were warranty jobs on a 2022; the same failure past 36,000 miles is a four-figure part. The two crashes are the parking-speed surge report that appears on every year of this generation — one in a rental car handed over that morning — and the fifth is a car that would not stop in reverse until the owner shut the hybrid system off; none of those three can be inspected for. Press the pedal hard at a stop and hold it: it should stay firm and the dash should stay dark.

Repair cost (estimate): $1,500–$3,000 for the brake booster assembly outside warranty

Odometer rollbacks in private sales; a screech from the speakers at startup; a steering wheel hot in one spotMedium

Seven electrical complaints, and two of them are the most useful warning on this page: buyers who bought a 2022 privately, one advertised at about 30,000 miles and one at 63,000, and learned at the DMV that the car had 173,000 on it. The Prius is a favourite of rideshare and delivery drivers, its mileage is a single number on a digital display, and that is a combination a fraudster likes. Before you buy any 2022, ask a Toyota dealer for the service history on the VIN and match the mileage on each visit to the odometer today; a gap of a hundred thousand miles is not a typo. Of the rest, two owners report a loud, ear-piercing noise from the speakers for a few seconds at startup — one dealer diagnosed a failed data communication unit, the telematics module; one owner has a spot on the steering wheel rim that gets hot enough to melt two dimples into the covering, which on a heated wheel is a shorted element and worth a call to Toyota before anyone drives it; and one finds the combination meter's warning icons washed out and unreadable in bright sun. Sit in it in daylight and start it yourself — the screech and the washed-out cluster both show themselves in the first five seconds.

Repair cost (estimate): $0–$1,500 — a warranty repair at the low end, a telematics unit outside warranty at the top

The generation's carry-over checks: coolant level for the heat exchanger leak, and the windshieldMedium

Two faults run through the earlier pages of this generation and there is no reason to think the last year is exempt. First, the exhaust heat recovery unit and EGR cooler carry engine coolant beside hot exhaust; when one leaks internally the coolant burns off out the tailpipe, the reservoir drops with no puddle, and the catalytic converter is the next casualty — owners on the 2018 and 2019 pages describe it, citing a Toyota bulletin for 2016–2019 cars that does not name the 2022. Second, the windshield cracks easily on this body, and because Toyota Safety Sense looks through it, a replacement needs the right glass and a camera recalibration. This year's record holds three engine and two visibility complaints we have not read the detail of, so we are flagging what to check rather than a proven 2022 pattern: the reservoir against its lines on a cold engine, and the bottom edge of the glass under the wipers.

Repair cost (estimate): $800–$2,000 for the heat exchanger or EGR cooler; $400–$1,000 for a windshield including camera recalibration
