Kestrel Take

903 complaints, 83 fires, and three quarters of the record is one word: engine. The second-generation Soul's direct-injection engines — the 1.6 with its self-destructing catalytic converter, the 2.0 that burns its oil down to the bearings — fail in ways that end with a stall at highway speed and, 62 times in this file, a fire. Kia has recalled this year twice for the engine bay and once more for a steering pinion that can let go of the rack. The car is genuinely likeable and the interior is a step up from the first generation, which is why so many are still on the road; but this is a purchase you make with the VIN lookup open and the dipstick in your hand. Every campaign closed, an engine that is quiet, full and dry, a scan with no knock-sensor or converter codes, and a receipt for a replacement engine if you can find one — that is the 2015 Soul to buy. Anything short of that, keep walking; there are plenty.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 903 owner complaints for the 2015 Kia Soul, 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. 76% 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 2015 Kia Soul

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

Engine failure and fires — 1.6 GDI catalytic converter breakup, 2.0 GDI oil consumption (two recalls)High — wallet impact

687 of 903 complaints, 62 of them fires. Two recalls sit behind them: 19V120 for 1.6L GDI cars, where an overheating catalytic converter breaks up, is drawn into the cylinders and destroys pistons and rods (the remedy is an engine control software update, which protects an engine still healthy and does nothing for one already damaged); and 20V750 for all 2014–2015 Souls, where dealers inspect the engine bay for fuel and oil leaks, test the engine, and repair or replace it as needed because of engine compartment fires while driving. Owners describe the same arc on both engines: oil consumption, a check-engine light, a P050A or P1326 code the dealer says has no fix, then a knock, a stall at 40–65 mph, and smoke from under the hood. Kia has offered extended engine coverage tied to these campaigns on some VINs — ask a Kia dealer with this VIN before you believe anything the listing says. At the car: dipstick full and clean, quiet idle with the hood up, and a fresh scan with no P0420, P1326 or P050A.

Repair cost: $0 with the recall — verify it was performed; $4,000–$7,500 for a replacement engine — around 94% of what this car is typically worth

Steering pinion plug can let the pinion gear separate from the rack — total loss of steering (recall)High — wallet impact

Recall 17V608 covers 2014–2016 Souls: the plug that retains the steering gear's pinion may allow the pinion to separate from the rack, and when that happens the wheel no longer turns the car. Dealers inspect and secure the plug or replace the whole steering gear, free. Eight of this year's 44 steering complaints report a crash. The rest describe the clunk and play from the electric power steering coupler that the earlier Souls also have — a cheaper problem, but on this year check the recall first and the coupler second. Run the VIN; if the campaign shows open, the car does not leave the lot until it is done.

Repair cost: $0 with the recall — verify it was performed; $150–$450 for a flex coupler if the wheel clunks

Headlights go out with the turn signal, push-button no-start, brake line corrosion, and easy theftMedium

A scattered cluster, but each part is checkable. Owners report the headlights flickering or switching off for a few seconds when the turn signal or high beams are used — new bulbs do not fix it, so it is the multifunction switch or a ground. Others have a push-button car that lights the dash but will not crank, which dealers could not reproduce. One had the brakes fail at 20 mph and was repaired under a Kia service campaign for corroded brake lines — worth asking a dealer about on any rust-belt car. And the 2015 Soul has no engine immobilizer, which is why it is a theft target; Kia's anti-theft software update is free at a dealer. At night, sit in the car and cycle the turn signal and high beams while watching the headlights on a wall.

Repair cost (estimate): $150–$500 for a multifunction switch

Automatic transmission jerks, slips and drops into limp modeMedium

62 power train complaints, eight of them fires that probably belong to the engine story. The rest describe the six-speed automatic jerking between gears, slipping under load, or the car going into a safe mode with a battery warning after a software update. Some of it is the engine dying underneath the transmission; some is a genuine transmission fault. Drive from cold, hold each gear under moderate throttle, and watch for a flare between second and third or a hard clunk into Drive. A transmission scan alongside the engine scan costs nothing extra.

Repair cost (estimate): $200–$600 for a fluid service and solenoid; $2,500–$4,000 for a rebuilt transmission — around 50% of what this car is typically worth

Accelerator pedal can bend and break — the car will not accelerate (recall)Medium

Recall 15V123 covers 2014–2015 Souls built July 21, 2013 to January 8, 2015: a section of the accelerator pedal arm can bend and fracture, leaving the driver unable to accelerate normally. Dealers add a rubber support under the pedal stopper, free, and the campaign began in March 2015 so most cars have had it. Look under the dash at the pedal — a cracked or visibly bent arm is a car that was never taken in. Confirm it on the VIN lookup alongside the other three campaigns.

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