Kia airbag lawsuits and NHTSA findings cover two separate problems. ARC Automotive airbag inflators, used by 13 automakers including Kia America, can rupture. Metal fragments can then enter the cabin.
ZF-TRW airbag control units in Hyundai and Kia vehicles are alleged to fail in a crash. Hyundai and Kia proposed a class settlement in July 2025 and admit no wrongdoing.
NHTSA decided in July 2024 that certain ARC inflators have a safety defect. It then paused its recall demand in December 2024 for more investigation.

Latest Kia Airbag Lawsuit Updates
July 28, 2025: Hyundai and Kia Reach Proposed Settlement
Hyundai and Kia reached a proposed class settlement over ZF-TRW airbag control units, ConsumerAffairs reported on July 28, 2025 [1]. The deal would end a suit that joins more than 20 class actions. The suit dates back to August 2019. A fairness hearing was scheduled for September 29, 2025, and its outcome has not been reported. The automakers admit no wrongdoing.January 17, 2025: NHTSA Announces Kia Niro Recall
NHTSA announced a Kia recall on January 17, 2025 [2]. FOX Business reported that it covers more than 80,000 2023-2025 Niro EV, plug-in hybrid and hybrid vehicles. Floor wiring can keep the front airbags from deploying properly. Dealers repair the vehicles for free. Owner letters were expected March 14, 2025.December 18, 2024: NHTSA Backs Away from ARC Recall Demand
NHTSA backed away from seeking a recall of nearly 50 million ARC inflators, the Associated Press reported on December 18, 2024 [3]. The agency’s notice, dated December 13, 2024, cited the need for more investigation. Automakers had argued that NHTSA “did not establish a systemic design defect.” The agency said further investigation is warranted. It may take public comment before any final decision.July 31, 2024: NHTSA Finds ARC Inflator Defect
NHTSA issued a supplemental initial decision on July 31, 2024. It confirmed that certain ARC and Delphi frontal air bag inflators contain a safety defect. The decision covers about 51 million inflators. It is an agency finding. It is not a court ruling. Kia America, Inc. is among the vehicle makers whose cars use the affected inflators.June 8, 2018: Kia Issues Airbag Control Unit Recall
Reuters reported on June 8, 2018 that Kia recalled more than 507,000 U.S. vehicles [4]. An airbag control unit could short circuit. A short circuit could prevent the frontal air bags from deploying in a crash. The models are listed under Recall and Regulatory Background.What Is an Airbag Inflator?
According to NHTSA, an air bag inflator is “a critically important component” of the air bag system [5]. It ensures that the bag “inflates a precise amount at a precise time.” A hybrid inflator “uses stored gas that is excited by propellant to fill the air bag cushion.” The NHTSA findings concern the inflator. The ZF-TRW claims concern the airbag control unit, a separate part.Who May Be Affected?
Owners and lessees of listed Hyundai and Kia models with ZF-TRW control units fall into the proposed settlement class. The class covers anyone who owned or leased such a vehicle on or before April 14, 2025. Listed Kia models include the 2010-2013 Forte and Forte Koup, 2011-2020 Optima and 2011-2016 Optima Hybrid. The list also has the 2011-2012 and 2014 Sedona, according to the Autoblog report on AOL [6]. Check your model and year against that list. Kia vehicles with ARC inflators fall under the separate NHTSA proceeding described in the updates above. A person hurt in a crash may have an injury claim apart from the settlement. Whether one exists depends on individual facts and legal review.Reported Injuries or Damages
The ZF-TRW suit alleges airbag control units that can fail in a crash because of electrical overstress. These are allegations. Regulator reports are separate. NHTSA’s July 2024 decision describes seven confirmed ruptures in U.S. vehicles. They injured at least seven people and killed one more. Metal fragments are ejected into the cabin when an inflator ruptures. NHTSA also said all of the subject inflators are at risk of rupturing. The Associated Press reported a separate tally of at least seven injuries and two deaths in the U.S. and Canada since 2009. In April 2014 in New Mexico, the driver-side inflator in a model year 2004 Kia Optima ruptured after the car hit a roadside barrier. Kia disputed NHTSA’s explanation, calling it “an isolated case of unknown cause.” Reuters reported crashes in which four people were killed and another six injured involving Hyundai and Kia. Reports are not proof that an airbag caused every injury.Recall and Regulatory Background
NHTSA says ARC inflators are installed in about 49 million U.S. vehicles from 13 manufacturers. NHTSA has made no final recall decision. It planned more information requests and possibly another comment period. A recall does not prove liability. Kia’s 2018 recall covers the 2010-2013 Forte, 2011-2013 Optima, and 2011-2012 Optima Hybrid and Sedona. A control unit may not deploy the airbags. For the Niro recall, call Kia customer service at 1-800-333-4542 and give reference SC332.Evidence to Preserve
Keep records that show which vehicle you owned and what happened to it:- Vehicle year, make, model and VIN
- Purchase or lease paperwork
- Recall notices and repair orders, including any airbag control unit or inflator work
- Photographs of the airbag, steering wheel or cabin after a crash
- Police and crash reports
- Medical records and bills
- Out-of-pocket repair receipts
- Letters and emails with the dealer or automaker
Filing Deadlines
Filing deadlines come from state law. They vary with where you live and when the crash or injury happened and was discovered. Filing after the deadline can end a Kia airbag injury claim, whatever the strength of the facts. A reader who is hurt should check with a lawyer promptly. Settlement claim forms have their own date. They are due by March 29, 2027 if the court approves the deal, and are filed at acusettlement.com.Potential Compensation
An injury claim may seek medical expenses, lost income, pain and suffering, and vehicle repair or replacement costs, depending on the facts. The settlement, proposed in July 2025 in Case No. 2:19-ml-02905 in the Central District of California, includes $2,500 for each of 20 original plaintiffs and reimbursement of reasonable out-of-pocket repair costs. Residual payments run up to $350 for a recalled vehicle and $150 for an unrecalled one. Compensation amounts vary by case. Past results do not guarantee future outcomes. Medical records and repair bills shape potential compensation.Frequently Asked Questions
