2012-2021 Kia Soul engine problems: which program fits your engine

Last reviewed 2026-10-09 · Data: NHTSA, official settlement and manufacturer documents · Independent site, not affiliated with Hyundai, Kia or NHTSA

Short answer

The Soul has more engine programs than almost any other model in our guides. The 2012-2016 Gamma 1.6L GDI and the 2014-2019 Nu 2.0L GDI are on Kia's Engine II settlement list (15 years / 150,000 miles for connecting-rod bearing damage, KSDS first). The 1.6L also has a catalytic-converter recall (19V-120) because overheating can damage pistons. The 2020-2021 2.0L Nu MPI has piston-oil-ring recalls (21V-259, and 25V-099 for certain 2021s). And most 2011-2019 Souls can't take the anti-theft software, so Kia offers an ignition cylinder protector instead.

Check your VIN to see recalls and which programs list your exact engine.

Which engines and years are involved

2012-2016, 1.6L Gamma GDI: Engine II settlement; catalytic converter / piston recall 19V-120.
2014-2019, 2.0L Nu GDI: Engine II settlement. For 2014-2016, Kia's KSDS campaign letter also promises a 15-year / 150,000-mile long-block warranty for connecting-rod bearing damage once KSDS is done.
2014-2015 Soul: engine-compartment fire recall 20V-750 (inspection plus KSDS update).
2020-2021, 2.0L Nu MPI: piston oil ring recall 21V-259; certain 2021s also in 25V-099.
1.6L turbo: not on the Engine II list.

What the settlement, campaigns and recalls say

KSDS (Knock Sensor Detection System) is free dealer software that listens through the knock sensor for the vibration pattern of a worn connecting-rod bearing. If it hears it, it turns on the check-engine light and limits engine power so the car can be driven to a dealer instead of the engine failing on the road. Kia's dealer letter names the trouble code P1326 for this condition.

Kia Engine II settlement (In re: Hyundai and Kia Engine Litigation II, C.D. Cal., final approval April 2024): extends the powertrain warranty to 15 years or 150,000 miles from original retail delivery, whichever comes first, for short-block and long-block damage caused by connecting-rod bearing failure, for original and later private owners. The KSDS update has to be done at a Kia dealer first.
Deadlines: cash claims (past repairs, towing, rental, fire losses) closed July 8, 2024. The extended warranty continues and needs no claim form. Kia's settlement site sometimes blocks automated visitors, so if it won't load, ask a Kia dealer to look up your VIN.
2014-2016 Soul 2.0 KSDS campaign: Kia's February 2024 renotice (code PI2002B on the letter) says the update is free, and that once it's done Kia warrants engine long-block repairs needed due to connecting-rod bearing damage for 15 years / 150,000 miles from the first date of service, for new and used owners. It warns that driving a long way in limp mode after KSDS triggers may void that extended warranty.
Recall 19V-120 (2012-2016 Soul 1.6 GDI): dealers update the catalytic-converter overheating protection software, replace the converter if damaged, and replace the engine if needed.
Recalls 21V-259 and 25V-099: inspect, replace the engine if needed, and install piston-ring noise sensing (PNSS) software.
Anti-theft: Kia's theft settlement notice lists the Soul 2020-2022 for the software and says 2011-2021 Souls (as a group) may not be able to take it. Those get Kia's CS2311 ignition cylinder protector. The multistate settlement site lists Soul 2020-2022.

Recall text quoted from NHTSA. Whether a recall is still open on a specific car can only be checked by VIN at NHTSA or the manufacturer.

What owners report to NHTSA

5,055 complaints have been filed with NHTSA for the 2012-2021 Soul. 3,258 of them name an engine component.

Source: NHTSA complaints API, pulled 2026-10-09. "Engine complaints" are complaints where the owner picked an ENGINE component (one complaint can list several components). Mileage is the median of mileages owners typed into their complaint text, shown only when at least 10 complaints mention one. Complaints are unverified owner reports, and counts reflect how many owners filed, not how many cars failed.

Engine complaints dominate: from 2014 on, about two-thirds to three-quarters of Soul complaints name the engine, and 2014-2016 also have the most engine fires in this table (57, 63 and 29). The mileage owners mention for 2012-2016 is high (roughly 80,000-100,000), which fits wear-related bearing and piston failures. 2020-2021 numbers are early-life complaints on a newer engine.

Warning signs to take seriously

Flashing check-engine light with the car limited to low RPM: KSDS has detected bearing wear. Kia's letter says engine speed is capped around 1,800-2,000 RPM. Get it to a dealer promptly.
Rattle from under the car, a sulfur smell, or power loss on a 1.6L: possible catalytic converter damage (19V-120).
Oil use between changes or knocking on a 2020-2021 2.0L.
Smoke or burning smell from the engine bay: stop, get out, call for help.

What to do, step by step

Check your VIN at NHTSA and owners.kia.com for open recalls and campaigns.
Confirm KSDS is done on a 1.6 GDI or 2.0 GDI. It's free and both the settlement and Kia's 2.0 campaign require it.
Keep oil-change receipts. Kia's letter says improper maintenance can affect the extended warranty.
With symptoms, call a Kia service department with the VIN and ask which extended engine warranty is on file before paying for diagnosis.
For theft protection, check customercare.kiausa.com/SWLD. If the software isn't available, ask for the CS2311 cylinder protector.

Dealer insider note

The Soul has more engine programs than most models, so the questions need to be specific. Per the guide above, the 2012-2016 Gamma 1.6L GDI and the 2014-2019 Nu 2.0L GDI are on the Engine II list. The 1.6L also has a catalytic converter recall, 19V-120. The 2020-2021 2.0L Nu MPI has piston oil ring recalls. Ask the advisor to confirm your engine from the VIN, then ask which of these apply.

If you add oil between changes, tell the advisor how often and ask for it to be noted on the repair order. Ask for the written outcome of any engine test. Ask about a loaner or rental if the car is held.

Most 2011-2019 Souls cannot take the anti-theft software, so Kia offers an ignition cylinder protector. Ask whether it has been installed on yours, and ask for the repair order showing it.

A used Soul buyer should ask the seller for: the KSDS record, recall repair history including the catalytic converter recall, any engine or converter replacement paperwork, and maintenance records. Ask a Kia dealer to run the VIN and print the result.

Until the campaign check is done, do not sign a customer-pay repair order or anything blank, and do not approve a paid engine repair or diagnostic fee without asking whether a campaign or settlement applies to your VIN.

If the shop stalls or says no, call the manufacturer's customer-care line (number is in your owner's manual). Give the VIN and repair order, ask for a case number, and keep every receipt.

Questions

Is my 2015 Soul 2.0 covered if the engine fails?

The 2014-2019 Soul 2.0L GDI is on the Engine II settlement list, and Kia's 2014-2016 campaign letter promises a 15-year/150,000-mile long-block warranty for connecting-rod bearing damage once KSDS is done. Whether a specific repair qualifies is Kia's call, so confirm with a Kia dealer using your VIN.

What does recall 19V-120 fix?

On 2012-2016 Soul 1.6 GDI, high exhaust temperatures can damage the catalytic converter and then the pistons. Dealers update the software, replace a damaged converter, and replace the engine if it's damaged.

Can my 2016 Soul get the anti-theft software?

Kia's theft settlement notice says 2011-2021 Souls may not be eligible for the software. Those can get a free ignition cylinder protector (CS2311). Check your VIN at customercare.kiausa.com/SWLD.

Is the Soul turbo included in Engine II?

We didn't find the 1.6L turbo on the Engine II list, which names the Gamma 1.6 GDI (2012-2016) and Nu 2.0 GDI (2014-2019).
