Engine And Engine Cooling:Engine:Hard Parts Internal/Mechanical — Kia 25V099 Piston Oil Ring Recall Effectiveness closed
On August 6, 2025, the Office of Defect Investigation (ODI) opened Audit Query (AQ) 25001 to assess the implementation of Kia America, Inc.’s (Kia) remedy program for Safety Recall 25V099, involving incorrectly manufactured piston oil rings which may damage the engine causing a loss of motive power or fire. This AQ was opened in response to consumer complaints alleging of an ineffective remedy, inconsistent inspection results to determine whether an engine replacement was needed, and the unavailability of recall remedies. On August 11, 2025, an Information Request (IR) was issued to Kia requesting: 1) why the inspection test was revised from requiring a ‘cold’ engine to a ‘warm’ engine; 2) w

Whether any of this applies to one specific Seltos
A campaign covers a build range, not a model year, so two identical-looking cars from 2021 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Kia publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.
Hear about a recall before the letter does
The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2021 Kia Seltos, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
The contact owns a 2021 Kia Seltos. The contact stated that when she took her vehicle in for an oil change, she was informed that there was no oil in the engine. The contact stated that the vehicle was leaking oil and there was a loud knocking sound coming from the engine. The contact stated no warning light was illuminated.
On 05/03/21 approx. 2:40 PM ct I was excelling to enter highway mopac north; austin, tx; when my car became sluggish; I pulled over, to shoulder, ironically tx roadside assitance pulled in behind me - we couldn't determine the issue - I was exiting the next exit driving to jiffy lube on anderson/spicewood; dialogue screen stating issue…
The driver side mirror is distorted. I drove it home from the dealership after having the dealer replace the mirror before we left the lot (we noticed it when before drove off the lot) then just drove and it was still warped. I was scared to switch lanes.
The first time I took my car out a rock hit the windshield and chipped it. Before I could make it home the chip had cracked my windshield and spread to beyond repair. The car has under 100 miles on it and already needs a new windshield. Vehicle was moving approx. 65 MPH on a 4 lane highway
No matter what speed, car will randomly jerk from left to right, feeling like death wobble. At higher speeds more than 45mph the car will violently jerk from left to right, feeling out of control. Kia dealership on central ave in albany ny USA notified, said the alignment was off and pass rear camber bolt is bent.
My Kia Seltos with only 900 miles has done the following twice: when at a stop and I step on the gas the car turns off. The first time it happened I was at a stop light and when I stepped on the gas the car turned off and took a couple of minutes before I was able to turn the car back on.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by Kia itself: 1 death-or-injury claim on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 1 injured, as claimed, not verified — about 1.2 per 100,000 built. Every Seltos model year, by year and system → Dated and by system, they are exhibit F of the defect dossier.
When owners reported it
miles, typically
Half the 88 owner reports with an odometer reading on file fall between 10,000 and 72,000 miles. That is when problems get reported, which is not the same as when they start — and not a failure rate, because nobody knows how many of these cars never had a problem at all.
Median mileage by component
| Component | Reports | Median miles | Vs same age |
|---|---|---|---|
| Engine | 66 | 55,547 | 1.11× |
| Power Train | 17 | 7,400 | 0.15× |
Vs same age is this model year’s median for the system divided by the median of every 2021-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported earlier than same-age vehicles: power train (0.15×). Which systems go early across the whole fleet: the component study.
Odometer readings as filed by owners with NHTSA. Readings under 100 or over 400,000 miles are dropped as data entry rather than history, and a component needs at least 12 readings before a median is shown for it.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.
Diagnostic trouble codes on file
Source: NHTSA manufacturer communications and complaintsCodes documented against this model year in the federal record. A code appearing here does not mean this vehicle will set it — it means the code is part of this nameplate-year's documented history.

Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2021 vehicle” is every 2021 model-year car, SUV and pickup inspected in the same window, all makes.

Seltos by model year
all years, side by side →Common questions about the 2021 Seltos
Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Kia Seltos have any recalls?
NHTSA has posted 2 recall campaigns for the 2021 Kia Seltos. The most serious on file is 25V099000, covering Engine And Engine Cooling. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2021 Kia Seltos?
NHTSA gave the 2021 Kia Seltos 4 stars overall in its New Car Assessment Program tests — 4-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it B (85/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2021 Kia Seltos?
Across the 3 EPA-rated configurations of the 2021 Kia Seltos, the best EPA combined figure is 31 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2021 Kia Seltos?
Transport Canada measured it at 172.0 in long, 70.9 in wide (body, without mirrors), 63.8 in tall, on a 103.5 in wheelbase. Curb weight: 2,892–3,318 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.
What do owners complain about on the 2021 Kia Seltos?
Owners have filed 378 complaints with NHTSA about the 2021 Kia Seltos, most often about engine, power train, electrical system. Of those, 13 involved a crash, 6 a fire, 8 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2021 Kia Seltos?
The EPA smog rating for the 2021 Kia Seltos is 5 out of 10. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III ULEV70, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2021 Kia Seltos?
The manufacturer has filed 134 service bulletins and related communications with NHTSA for the 2021 Kia Seltos, most often covering electrical system, power train, engine. The most recent is dated 2026-06-08. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.
How does the 2021 Kia Seltos do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Kia Seltos failed the emissions check on 0.94% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 2.4% (every 2021 vehicle: 1.5%). The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.

Sources & method
Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.
EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly.
