Kestrel Take

The biggest record of the third-generation Rio — 77 complaints — and 41 of them are the 1.6L GDI engine burning oil, clogging its catalytic converter, and in five cases catching fire. Almost all of it was filed in 2023 and 2024, when these cars crossed 80–120k miles and the ABS-module fire recall landed with no parts to fix it. The car is honest transportation and cheap to insure, so the decision is entirely about the engine in front of you: dipstick full, cold start quiet, converter not glowing, both recalls closed, and receipts. Get those five things and it is a reasonable $7,000 car. Miss any one and you are buying somebody else's engine problem.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 77 owner complaints for the 2016 Kia Rio, and 2 recall campaigns.

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. 53% of them are about one thing — the engine. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

2 recall campaigns cover 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.

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

Known Issues for the 2016 Kia Rio

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

1.6L GDI oil consumption — burnt-oil converter, rod knock, and five engine firesHigh — wallet impact

More than half the record. Owners who kept up with oil changes still report the engine drinking a quart or more between them, with three shops finding no leak; the oil goes out the exhaust, plugs the catalytic converter, and the check-engine light comes on for the converter first. Left alone it ends in a rod knock, a seized engine at highway speed, or — in five complaints here — a fire after a loud bang under the hood. One owner says the car failed Kia's own oil-consumption test and cites a class action; whether this VIN has any coverage is a question for a Kia dealer with the VIN in hand, not something to assume. Check the dipstick cold and after the drive, and ask when the converter was last replaced and why.

Repair cost (estimate): $1,000–$2,000 for a catalytic converter; $3,000–$5,500 for a used or rebuilt engine — around 76% of what this car is typically worth

ABS hydraulic unit can short and start a fire while parked — recall parts took months (recall)High — wallet impact

Recall 23V652 covers 2012–2017 Rios: the hydraulic electronic control unit for the ABS can leak internally, short, and start an engine-compartment fire whether the car is running or off. The fix is a new fuse, free at a dealer. Most of the 18 brake complaints on this year are owners saying the recall letter arrived in late 2023 and the part did not come for six months or more. Two are crashes: one an engine lock-up at speed that took the power steering and brake assist with it, one an ABS and tyre-pressure light followed by a slide into a ditch. Check the VIN on NHTSA's recall lookup before you drive it, and do not garage the car until the recall shows closed.

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

Stalls, an ignition that will not release the key, and three engine-bay firesHigh — wallet impact

Eight electrical complaints and three of them are fires: a stall with the radio still playing, then flames; a flashing check-engine light and surging, then fire out of the hood as the owner reached for the latch. The non-fire ones are a car that stalls repeatedly and needs the key jiggled to crank, spark plugs fouling every 20–30k miles from burnt oil, and a key that sticks in the ignition. Several of these are the oil-consumption engine and the ABS-module recall wearing a different label. On your visit, start it three or four times, pull the key out each time, and watch the dash for a flashing check-engine light on the drive.

Repair cost (estimate): $200–$1,500 for wiring, ignition switch or module repairs before a fire; after one the car is a write-off

Trunk latch base can crack so the trunk cannot be opened from inside (recall)Low

Recall 23V594 covers 2016–2017 Rios: the trunk latch base may crack, which stops the emergency release from working from inside the trunk. Dealers replace the latch base for free. Not a wallet item and not a driving hazard, but it is a federal safety standard the car fails until it is done, and it is a two-second VIN check alongside the ABS recall.

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

Hesitation and hard shifts from the six-speed automatic; headlights dimming or failingMedium

Five power-train complaints describe the automatic hesitating from a stop or banging into gear, and four exterior-lighting complaints describe headlights that dim or go out — on a 2016 Rio that is usually the bulb socket or a corroded connector rather than the lamp. Neither is a pattern the size of the engine, but both are worth two minutes: pull away from three stops and feel for a pause, and turn the headlights on and off several times while a friend watches from the front.

Repair cost (estimate): $100–$1,200
