Kestrel Take

A genuinely good rear-drive sports sedan — and the first year of it, with four recall campaigns and five fires among 67 complaints to show for that. Three of those recalls are fire or power-loss campaigns: a wiring harness rubbing a burr on the fender, an electrical junction box, and a turbocharger oil feed pipe that deteriorates and drips oil onto hot metal. A fourth covers the high-pressure fuel pump that makes the car go flat uphill. Every one of them is free to fix, which makes this car a straightforward purchase with one non-negotiable step: run the VIN through NHTSA's recall lookup and confirm all four are closed. Do that, get the service history for the 3.3T, and the driving experience is worth the money. Skip it and you are buying somebody else's open fire recall.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 67 owner complaints for the 2018 Kia Stinger, and 4 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. 37% 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.

4 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 2018 Kia Stinger

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

Left turbocharger oil feed pipe leaks oil onto hot parts — fire risk (recall)High — wallet impact

Recall 24V169 covers 2018–2023 Stingers with the 3.3-litre twin-turbo: the left turbo's oil feed pipe and hose assembly deteriorates and leaks oil onto hot engine components, which can start an engine compartment fire while you are driving. Dealers replace the pipe and hose free. This is the likeliest explanation for the burning-oil smell and smoke-from-under-the-bonnet complaints in this record, including one car that did it three hours after a routine oil change. Open the bonnet after a test drive and look for oily wet film on the heat shielding around the left turbo.

High-pressure fuel pump valve sticks — the car goes flat, especially uphill (recall)High — wallet impact

Recall 23V634 covers 2018–2021 Stingers: the fuel control valve plunger can stick inside the high-pressure fuel pump, over-pressurise the rail and take away drive power. Fifteen complaints here describe exactly that — sputtering under acceleration, a collapse in fuel economy, black soot at the tailpipe, and code P0088 for fuel rail pressure too high, with one owner losing power at 75 mph. The remedy is an ECU software update plus a pump replacement where needed, and several owners complain the software went on but the pump did not. Ask which was actually done.

Front wiring harness chafing on a fender burr can short and catch fire (recall)High — wallet impact

Recall 18V754 is specific to 2018 Stingers built July 2017 to June 2018: the front wiring harness can rub against a metal burr on the left fender panel, wear through, short out and start a fire. Dealers inspect the harness and either fit a protective cover or replace the damaged loom. Four of the eleven electrical complaints on this year involve fire, and one owner spent months chasing a dealer that could not get the part. This is the oldest of the four campaigns, so it is also the one most likely to have been done — but confirm it rather than assume it.

Engine bay fire from the electrical junction box — fuse kit campaign (recall)High — wallet impact

Recall 20V518 started on 2019 cars and was expanded at the end of 2020 to take in 2018–2021 Stingers: an engine compartment fire can start while driving, and the remedy is a new fuse kit installed in the electrical junction box. Kia told owners to park outside and away from buildings in the meantime. Because this one was added by expansion rather than at launch, plenty of 2018 owners never got a first letter — which makes it the campaign most worth checking by VIN on a car this age.

Oil pressure switch leaks, oil runs low, and cylinder 3 misfires into an engine replacementHigh — wallet impact

Separate from the recalls, several owners describe the same sequence: the oil pressure switch weeps, the oil level drops without a warning light, and then cylinder 3 starts misfiring. One owner changed plugs four times and replaced coil packs before a dealer found the engine would no longer hold pressure and needed replacing. Another reports Kia extended coverage on the oil pressure switch to 15 years or 150,000 miles on some cars but not theirs — ask a Kia dealer to check this specific VIN for that coverage, because we cannot confirm the terms from the public record. Check the dipstick yourself on a level surface before the test drive.

Repair cost (estimate): $300–$700 for the oil pressure switch; $7,000–$11,000 for a replacement 3.3T engine — around 58% of what this car is typically worth

Walk-Away Red Flags

✗Burning oil smell or a haze of smoke from the front of the car after a hard drive
✗Oily wet film on the heat shielding around the left turbocharger
✗Hesitation or a flat spot pulling uphill with the check-engine light on
✗Black soot around the tailpipe tips on an otherwise clean car
✗Hazard lights that flash by themselves or change flash speed
✗Oil level below the bottom of the dipstick hatching on a level surface

Good Signs

✓All four recall campaigns shown closed on the NHTSA VIN lookup
✓A dealer invoice showing the left turbocharger oil feed pipe and hose replaced
✓The high-pressure fuel pump itself replaced under the recall, not just the ECU software
✓Oil changes at 5,000 miles or less with turbo-rated oil, with receipts
✓A clean scan at an independent shop with the engine at operating temperature
