Used Kia Forte 2nd Gen (2014-2018): Buyer's Guide

Kia's 2.0L Nu engine, the one under the hood of most 2014-2018 Forte EX models, is named directly in a $1.3 billion Kia and Hyundai class-action settlement over connecting rod bearing failure. The defect can cause the engine to seize, stall, or in rare cases catch fire. You didn't need to have a failure to be covered: every 2014-2018 Forte and 2014-2016 Forte Koup with a Nu engine qualifies for a 15-year, 150,000-mile extended warranty under that settlement, whether or not the current owner ever filed a claim.

That single fact changes how you should shop this generation. The second-gen Forte (codenamed YD) is otherwise a cheap, roomy, well-equipped compact that regularly clears 150,000 miles. But which engine is under the hood, and whether the connecting rod warranty and two separate recalls were ever used, matters more here than trim level or color. This guide breaks the YD-generation Forte down by powertrain so you know exactly what you're buying.

Beyond the headline engine story, this generation also carries a handful of smaller, well-documented owner complaints worth knowing about before you shop: exterior lighting that can flicker or fail on early cars, backup cameras and side mirror motors that fail out of warranty, and a trunk latch recall on four-doors and Koups built between 2016 and 2018. None of those are dealbreakers on their own. Combined with an unaddressed engine recall, they add up fast.

This Generation at a Glance

Kia fully redesigned the Forte for the 2014 model year on the YD platform, growing the car and sharpening its exterior design with cues borrowed from the Optima. The sedan came in LX and EX trim; the Forte5 hatchback and Forte Koup coupe were sold alongside it in EX and SX trim, with the Koup adding a manual-friendly sport character. Kia gave the whole lineup a mid-cycle facelift for 2017: revised LED headlights and taillights, a new front bumper, and standard Apple CarPlay and Android Auto on most trims. The Forte Koup was discontinued after the 2017 model year, a casualty of falling coupe demand as buyers moved to crossovers; the Forte5 hatchback didn't survive the redesign to the third-generation Forte in 2019, either.

Three drivetrains span the generation, and none of them changed dramatically in output year to year, but the fuel delivery system underneath the 2.0L did change, which matters for the reliability story below. Every configuration is front-wheel drive; Kia never offered all-wheel drive on this generation of Forte.

Powertrain & Trim Breakdown

2.0L Nu: The One With the Lawsuit

The 2.0L Nu four-cylinder is the volume engine in EX-trim sedans, Forte5 hatchbacks, and Forte Koup coupes across this entire generation. Early cars (roughly 2014-2016) ran direct injection; NHTSA's own recall filing for the 2017-2018 model years explicitly labels that later version a multi-port-injection design, meaning Kia changed the fuel delivery system partway through the generation without a marketing announcement.

Both versions are named in the Hyundai and Kia Engine Litigation II settlement, which resolved claims that Nu GDI, Gamma GDI, and Theta II MPI engines share a manufacturing defect in the connecting rod bearings. Worn bearings can let a rod knock, seize the engine, or in the worst documented cases puncture the block, leaking oil that the lawsuit alleges can ignite into a fire. Per the settlement's own coverage list, that applies to 2014-2018 Forte sedans and Forte5 hatchbacks, plus 2014-2016 Forte Koup coupes, all with the Nu engine. You do not need a documented failure to claim the remedy: a 15-year, 150,000-mile extended warranty covering inspection and repair of connecting rod bearing damage, plus reimbursement options for owners who already paid to fix it themselves.

Separately, NHTSA campaign 21V260000 recalls 2017-2018 Fortes built with the 2.0L Nu MPI engine specifically. Foreign particles can lodge in the oil pump's variable relief plunger, starving the engine of lubrication. Kia's fix replaces the oil pan (which houses the pump) and the oil filter, and adds magnets to the new pan to catch debris going forward. The consequence Kia documented: a damaged engine can stall while driving, which raises crash risk.

Owners on Kia Forte Forum's engine and reliability threads describe the failure signature consistently: a rod knock that gets louder under load, rising oil consumption before that, and in a minority of cases a stall at speed with no warning light. Ask for the seller's Kia connecting rod bearing settlement status alongside their recall history: a Forte with the extended warranty already registered to the VIN is a materially safer buy than one where neither the settlement nor the recall was ever addressed.

Away from the engine itself, EX-trim cars in this range also show up in owner reports for a handful of smaller electrical gremlins: an intermittent speaker dropout that Kia traced to a software glitch, side mirror motors that burn out one at a time rather than together, and backup cameras that develop internal moisture and fail. None of those are safety recalls, and none of them are unique to the 2.0L specifically, but they're common enough across EX and higher trims that they're worth budgeting for as wear items rather than being surprised by them at 70,000-plus miles.

Air Conditioning and Cooling: A Cross-Engine Owner Complaint

It isn't tied to one specific engine, but it's common enough across the generation to call out on its own: A/C compressor failure. Forte Forum threads describe compressors seizing around the 100,000-mile mark across multiple engines and model years, usually preceded by a period of intermittently warm air or a growling noise when the compressor clutch engages. A seized compressor can also send metal debris through the rest of the A/C loop, meaning a full compressor swap sometimes turns into a condenser and line replacement too. Ask when the A/C was last serviced and whether it's ever lost refrigerant charge without an obvious leak found; that pattern often precedes a compressor going out.

1.8L Nu MPI: The Base Engine Kia Quietly Dropped

LX-trim sedans from 2014 through 2016 used a smaller, non-turbo 1.8L version of the Nu engine, including a fuel-economy-focused "Forte Eco" trim in the 2014 model year that Kia didn't repeat afterward. By the 2017 facelift, Kia had dropped the 1.8L entirely and standardized the sedan lineup on the 2.0L.

A law firm investigation flagged 2011-2016 Forte LX 1.8L models for premature engine failure, citing knocking noises, stalling, and sludge as warning signs. Put that in context: roughly 80,000 Fortes sold in the US and Canada in 2014 alone, and NHTSA's own complaint count for 2014 engine failure sits in the low hundreds, not the thousands. That's a real but minority-case risk, not a defining trait of the 1.8L the way the connecting rod issue defines the 2.0L. Owners on Kia Forte Forum report 1.8L cars clearing 100,000 and even 260,000 miles with routine maintenance and no major engine work. Treat the 1.8L as the safer, lower-drama engine choice in this generation, but still check for a cold-start knock and confirm oil changes were done on schedule.

Because the 1.8L was exclusive to LX-trim 2014-2016 sedans, any 1.8L Forte you're looking at is also old enough to fall under the two model-year-specific recalls that hit 2014 Fortes regardless of engine: a brake pedal stopper pad that can deteriorate and leave the brake lights on continuously, or in a worse case let the shifter move out of park without the pedal depressed (NHTSA campaign 17V773000), and a cooling fan resistor that can overheat and melt (campaign 15V015000), which Kia's own filing says raises the risk of a vehicle fire. Both are inexpensive dealer fixes once you know to ask, but a 2014 LX where neither has been done is not a car to buy on a handshake.

1.6L Gamma Turbo GDI: The Koup and SX Engine

The 1.6L turbocharged Gamma engine powers SX-trim Forte5 hatchbacks and every Forte Koup, making it the enthusiast pick of the generation at 201 horsepower. Owners on Kia Forte Turbo Forum consistently flag two things: it needs oil changes every 5,000 miles rather than the 7,500-mile interval Kia lists for the non-turbo engines, because direct injection and turbo heat both accelerate oil breakdown faster. And the earliest cars, built in the 2014 model year before Kia revised the internals, ran comparatively softer pistons and connecting rods. Forum consensus is that 2015-and-later Gamma turbos received strengthened internals, making a 2014 build the one to be most cautious about if the car has ever been modified or driven hard.

Low-speed pre-ignition, a phenomenon common to small turbocharged direct-injection engines under low-RPM, high-load conditions, shows up in forum threads as a cause of occasional catastrophic failure on modified cars. A stock, well-maintained 1.6T with documented 5,000-mile oil changes is a different risk profile than one with an aftermarket tune or unknown service history. Ask directly whether the car has ever been tuned. If a seller can't answer, assume yes and price the risk in.

The 1.6T is also the reason the Koup and SX-trim Forte5 attract a different buyer than the plain sedan: it's the only way to get real power out of this generation, and it's the trim most likely to have led a hard life. A Koup or SX Forte5 with a clean Carfax, no aftermarket exhaust or intake, and a paper trail of 5,000-mile oil changes is a genuinely fun, reasonably reliable used buy. One with worn tires, an aftermarket exhaust, and gaps in the service record is a different car entirely, even if the VIN and body style are identical.

Trim Levels

The 2017 facelift is the equipment line worth paying up for if smartphone connectivity matters to you: it's the first model year where Apple CarPlay and Android Auto came standard rather than through an aftermarket head unit swap. Earlier LX trims with the 1.8L Eco package (2014 only) sacrifice a little power for the best fuel economy in the non-turbo lineup, worth seeking out if you do a lot of highway commuting and don't need the extra output of the 2.0L.

Body style matters here almost as much as trim. The Forte5 hatchback and Forte Koup coupe share their mechanicals with the sedan but sell for meaningfully different money on the used market: the Koup in particular is a smaller, thinner slice of the used inventory now that Kia stopped building it after 2017, so expect fewer choices and slightly more variance in condition. The Forte5 is the practical middle ground, offering hatchback cargo flexibility on the same 2.0L or 1.6T powertrains as the sedan and coupe. If cargo space and rear-seat access matter more to you than styling, the Forte5 is worth cross-shopping against the sedan even if you weren't originally looking at a hatchback.

Which Model Years to Target Within This Gen

The 2014 model year carries the most owner complaints of the generation and pairs that with the least-developed version of every engine in the lineup: pre-revision turbo internals, and the only model year hit with both the brake pedal switch recall and the cooling fan resistor fire recall. The 2015 shows zero recalls in CarScout's NHTSA-sourced data, but owner reports of random exterior lighting failures around 56,000 miles keep it out of the "good" tier. 2016 and later benefit from stronger 1.6T internals and, from 2017 on, the facelift's better infotainment and lighting.

2016 is the sweet spot if you want the strongest pre-facelift car: it's a full model year removed from the 2014 launch issues, it predates the oil pump recall entirely, and the Koup was still in production that year (Kia didn't drop the body style until after 2017). 2017 and 2018 are the better pick if smartphone connectivity and the updated interior matter more to you than a wider body-style choice, since both get the facelift's standard CarPlay and Android Auto, though 2017 is also the last year you can still find a Koup if that's the body style you want. Either way, budget time to confirm the oil pump recall was actually completed, since owner letters for that campaign didn't go out until August 2021, three to four years after those cars were originally sold, meaning plenty of them changed hands at least once before the recall notice ever arrived.

The connecting rod bearing settlement applies across the full 2014-2018 range regardless of which year you pick, so check settlement and recall status on any Forte you're seriously considering, not just the ones flagged here.

Pre-Purchase Inspection Checklist

2.0L Nu (2014-2018 EX, Forte5, Koup):

• Start the engine cold. Listen for a knock that fades as the engine warms; that fade pattern is consistent with connecting rod bearing wear reported on Kia Forte Forum threads.
• Check the oil on the dipstick for a burnt smell or metal flecks, and ask whether the connecting rod bearing extended warranty (from the Kia/Hyundai engine settlement) has ever been registered or used on this VIN.
• Ask if the oil pump recall (campaign 21V260000, 2017-2018 only) was completed. It replaces the oil pan and filter.

1.8L Nu (2014-2016 LX):

• Confirm oil change intervals from service records; sludge from delayed changes is the leading precursor to the failures the LX 1.8L investigation flagged.
• Listen for stalling or rough idle right after a cold start.

1.6L Gamma Turbo (SX, Koup, all years):

• Ask specifically whether the ECU has ever been tuned or the boost modified. A stock, unmodified 1.6T is a materially safer buy.
• Confirm 5,000-mile oil change intervals in the service history, not the longer 7,500-mile schedule that applies to the non-turbo engines.

All engines:

• Run the VIN through a recall check before you agree on a price.
• On 2016-2018 four-doors and Koups, ask whether the trunk latch recall (21V622000) was completed; an unrepaired trunk can trap someone inside from the exterior release failing.
• Test the A/C on max cold for a full five minutes, not just a quick blast; intermittent cooling or a growling noise from under the hood are early compressor-failure symptoms reported across the whole generation.
• Cycle both power side mirrors and test the backup camera image for moisture spots or a washed-out picture; both are common out-of-warranty failure points on this generation regardless of engine.
• Test every speaker at low and high volume; a software glitch some owners report can cut audio out entirely, and it's a cheap diagnostic that takes thirty seconds.

Running Costs

RepairPal estimates the Forte's average annual maintenance cost at roughly $451, below the compact-car average. That number assumes routine service on a healthy engine; it doesn't include a connecting rod bearing repair, an A/C compressor replacement, or an oil pump swap, which is exactly why registering for the settlement's extended warranty coverage matters even on a car that currently runs fine. Insurance costs on this generation tend to run below the compact-car average for the LX and EX sedans, and noticeably higher for the SX-trim 1.6T cars and the Koup, both because of the added performance and because coupes generally carry a higher risk rating than four-door sedans of the same size.

Parts costs are a genuine advantage of this generation regardless of engine: this is a high-volume Kia platform with a decade of aftermarket and salvage-yard supply behind it, so routine repairs like alternators, starters, and suspension components tend to price meaningfully below what you'd pay for the same repair on a comparable Honda or Toyota. The exception is the 1.6L turbo, where turbo-specific components and shorter service intervals push total cost of ownership closer to what you'd pay on a non-Kia compact with a similar engine.

FAQ

Is the 2014-2018 Kia Forte's 2.0L engine reliable? It's covered by a national class-action settlement over connecting rod bearing defects that can cause seizure or stalling. Kia's remedy is a 15-year, 150,000-mile extended warranty on any 2014-2018 Forte or 2014-2016 Koup with the Nu engine, whether or not you've had a failure yet.

What year Kia Forte should I avoid? 2014 combines the highest owner complaint volume in the generation with the least-developed engines: pre-revision turbo internals and two separate recalls specific to that model year alone. 2015 is a close second for caution, mainly for reported lighting failures.

How many miles does a 2nd-gen Kia Forte last? Owners on Kia Forte Forum report 1.8L and 2.0L cars clearing 150,000 to 260,000 miles with routine maintenance. The connecting rod bearing defect is the main thing standing between a Forte and that kind of lifespan, which is why the settlement's extended warranty matters more than the odometer reading.

Is the Forte Koup worth buying used? The Koup pairs the 201-horsepower 1.6L turbo with sharper styling, but it was discontinued after 2017 due to weak sales, so parts availability and resale demand are thinner than for the sedan. It's a fine buy if you get a stock, well-documented example with 5,000-mile oil changes on record.

Did Kia ever recall the 2014-2018 Forte for a fire risk? Yes. Campaign 15V015000 covers 2014 Fortes where the cooling fan resistor can overheat and melt, which Kia's own filing says increases fire risk. Confirm that recall's completion status on any 2014 model before buying.

Bottom Line

The 2016 through 2018 Forte, in any engine, is the safer window in this generation: stronger internals, the 2017 facelift's better lighting and standard CarPlay/Android Auto, and fewer recalls tied to that specific model year alone. But the connecting rod bearing settlement covers the entire 2014-2018 run, so check it on any Forte you're considering, run the VIN through a recall check, and confirm the seller has actually used the settlement's extended warranty rather than just knowing it exists.
