2018 Kia Forte Recalls, Problems & Maintenance

The 2018 Kia Forte carries 3 open NHTSA recalls — most recently covering air bags and latch. Owners report 6 recurring issue clusters, led by “Trunk latch failure and unintended opening.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.

AIR BAGS

Campaign #22V031000 · Jan 25, 2022

Issue: Kia Motors America (Kia) is recalling certain 2017-2019 Sedona, Soul, Soul EV, 2017-2018 Forte, and 2017 Forte Koup vehicles. The Air Bag Control Unit (ACU) cover may contact a memory chip on the printed circuit board and damage the electrical circuit. Circuit damage may result in deactivated air bags that will not deploy in a crash.

Risk: Air bags that do not deploy as intended can increase the risk of injury in a crash.

Fix: Dealers will inspect the ACU, and either update the software or replace the unit, as necessary. Repairs will be performed free of charge. Owner notification letters were mailed March 21, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC226.

LATCHES/LOCKS/LINKAGES:TRUNK LID:LATCH

Campaign #21V622000 · Sep 8, 2021

Issue: Kia Motors America (Kia) is recalling certain 2016-2018 Forte 4-door, Forte Koup 2-door, and 2018-2019 Rio 4-door vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

Risk: A person inside the trunk compartment may become trapped, increasing their risk of injury.

Fix: Dealers will replace the trunk latch assembly, free of charge. Owner notification letters were mailed on February 10, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC216.

Issue: Kia Motors America (Kia) is recalling certain 2017-2018 Forte vehicles equipped with a 2.0L Nu MPI engine. Foreign particles may stick inside the oil pump, which may cause an oil pump failure and engine damage.

Risk: A damaged engine may stall, increasing the risk of a crash.

Fix: Kia will notify owners, and dealers will replace the oil pan, free of charge. Owner letters were mailed August 16, 2021. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC210.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 3,750 mi

Severe service: every 3,750 miles. Normal: 7,500 miles. Theta II 2.0L/2.4L on Optima, Sorento, Sportage (2011-2019): full synthetic only, never extend.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Often free at the shop where you bought the tires — worth asking before paying.

Fatal crash history & reported problems

How the 91 occupant deaths break down

66

driver deaths

25

passenger deaths

91

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 2018 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
