Kestrel Take

The last Rio sold in the US, and a record of twelve complaints with no recalls, no crashes and no fires. We want to be plain about what that means: it means the car is two or three years old and rare, not that it has been proven. Twelve reports cannot show a pattern, and the 1.6L engine is the same family that burned oil in older Rios once they passed 80k — this year has not got there yet. What owners did file is small and checkable: a cold-start rattle, a couple of stalls on warm-up, one dead transmission at low miles, and three cars that wander on the freeway. Most 2023s still carry Kia's warranty, so the sensible buy is one with the warranty balance confirmed in writing, a straight-tracking test drive on a highway, and a quiet cold start. Then keep the oil-change receipts; the next owner will want them.

What we checked

Checked against public records, 2026-09-25

NHTSA holds 12 owner complaints for the 2023 Kia Rio, and no recall campaigns.

That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under the engine (3), steering (3), the transmission and drivetrain (2). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.

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

Known Issues for the 2023 Kia Rio

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

Rattle at cold start and stalls during warm-up on the 1.6LMedium

Three engine complaints. One is a rattle for the first seconds after a cold crank that the dealer could not reproduce once the car was warm; two are the engine dropping revs and dying during warm-up or at a stop, restarting after several tries. On this engine a brief start-up rattle can be the timing-chain tensioner bleeding down or a heat shield, and a warm-up stall is often a throttle body or idle-learning problem cured with a clean and a reflash. Both are warranty items on a 2023, so the check is simple: ask to be the one who starts it cold, and sit at idle for two full minutes before you drive.

Repair cost (estimate): $150–$900 for a throttle body, tensioner or reflash outside warranty; $0 if Kia's coverage still applies

Wanders on the freeway — needs constant steering correction above 55 mphMedium

Three steering complaints, all the same feeling: the car will not hold a centre line, small wheel inputs turn into bigger changes of direction, and crosswinds make it worse. One owner found the wheel off-centre from the day of delivery. On a 1.1-ton car with narrow tyres this is usually alignment, tyre pressure or a tyre with a belt problem, and occasionally the electric power-steering calibration. Drive it on a highway with a light grip for two miles and see whether it tracks; then check the tyre pressures and look at the wear pattern across each front tyre.

Repair cost (estimate): $100–$250 for an alignment; $400–$800 if front tyres are needed

Six-speed automatic stopped shifting at 10 mph — replaced under warrantyMedium

Two power-train complaints: one is the warm-up stall counted again, and one is a transmission that stopped shifting at 10 mph with the revs rising and no speed, which the dealer confirmed was dead. A single failure on a young car is not a pattern, and the powertrain warranty covered it. What it tells a buyer is to make three brisk pulls from a stop on the test drive and feel that every upshift arrives, and to ask whether this car has ever had transmission work.

Repair cost (estimate): $2,500–$4,500 for a replacement transmission outside warranty; $0 if Kia's powertrain coverage still applies — about 30% of what this car is typically worth

Source: NHTSA complaints filed under the transmission and drivetrain (2).

Small electrical and suspension complaints — two each, no shared partLow

Two electrical complaints and two suspension ones, none describing the same fault twice. On a car this new they are more useful as a checklist than a warning: cycle every window, the infotainment screen and the rear camera; and on the drive, cross a speed bump slowly and listen for a knock from either front corner. Anything you find is warranty work if the coverage has transferred, and a negotiating point if it has not.

Repair cost (estimate): $100–$500 outside warranty; $0 if coverage has transferred

Source: NHTSA complaints filed under electrics and electronics (2), the suspension (2).
