The passenger frontal airbag deployed on its own while the vehicle was being driven, with no collision or impact that the driver is aware of. The driver airbag did not deploy. The incident occurred on October 4, 2026, at about 11:14 PM, shortly after the driver refueled at a gas station and was heading toward the highway. The airbag tore open the dashboard panel and cracked the windshield from the inside where the bag struck the glass. The driver brought the vehicle back to the gas station and it was towed. It has not been driven since. Safety risk: The sudden deployment startled the driver and the cracked windshield reduced visibility while the vehicle was moving. Anyone in the passenger seat would have been struck at close range. Recall history: This vehicle received the Recall 174 / the federal safety agency 18V‑137 airbag control unit remedy (ACU main wiring harness installation, part 91700-4R100-QQH) at a Hyundai dealer in September 2025, at about 305,800 miles. The deployment occurred about 13 months and 18,400 miles later, at 324,243 miles. Warning signs: No airbag warning light or other warning appeared before the deployment. The vehicle was serviced at a Hyundai dealer about one month earlier (oil change and multi-point inspection), and no airbag or restraint-system problem was reported. Inspection: The vehicle is at a Hyundai dealer and is available for inspection. We have asked that the airbag control unit, airbag module, and stored crash data be preserved. A case has been opened with Hyundai Motor America. As of this report, the vehicle has not been inspected by the manufacturer, police, or an insurer, and no dealer has confirmed the cause. Cause: UNKNOWN. Our best assessment is an electrical fault in the airbag control unit or its wiring, which received recall work in 2025.

Air bags: air bag/restraint control module
- What is wrong
- Hyundai Motor America (Hyundai) is recalling certain 2011-2013 Sonata and 2011-2012 Sonata Hybrid vehicles. On February 27, 2018, Hyundai Motor Company (Hyundai) notified the federal safety agency that they were recalling 154,753 model year 2011 Sonata vehicles. On April 18, 2018, Hyundai expanded the recall to include an additional 425,305 model year 2012-2013 Sonata and 2011-2012 Sonata Hybrid vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags, seat belt pretensioners, and side air bags from deploying.
- Risk
- If the frontal air bags, seat belt pretensioners, and side air bags are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
- Remedy
- Hyundai will notify owners, and dealers will install an external wire filter kit, free of charge. The recall began October 15, 2018. Owners may contact Hyundai customer service at 1‑855‑371‑9460. Hyundai's number for this recall is 174.

Air bags may be disabled during crash
The Office of Defects Investigation (ODI) opened PE18-003 on 3/16/18 to investigate incidents involving crashes, resulting in significant collision related damage, where the frontal airbags failed to deploy. ODI reviewed complaint data, available design, test, and field data on the model year (MY) 2011 Hyundai Sonata, MY 2012-2013 Kia Forte and Forte Koup vehicles. ODI also evaluated data from the automotive air bag system supplier, ZF-TRW (ZF), to review vehicles that may contain the same air bag control unit (ACU) used in the subject vehicles. Hyundai Motor America (HMA) issued recall No. 18V‑137 for MY 2011-2013 Sonata and MY 2012 Sonata Hybrid vehicles. Kia Motors America (KMA) issued recall No. 18V‑363 for MY 2010-2013 Kia Forte and Forte Koup, MY 2011-2013 Optima, MY 2011-2012 Optima Hybrid, and MY2011-2012 Sedona vehicles. The two recalls address vehicles containing ACUs manufactured without adequate circuit protection by installing a wire harness filter kit to prevent internal damage to the ACU. In the event of a crash, ACU damage may result in the disablement of the vehicle's airbags. Each respective manufacturer has mailed letters to affected vehicle owners informing them of the remedy and its availability. ODI plans to evaluate the susceptibility of the subject ACU to electrical signals, as well as other vehicle factors that can either lead to, or reduce the likelihood of, an electrical overstress event in other vehicles manufactured with the subject ZF ACU.Accordingly, this Preliminary Evaluation has been upgraded to an Engineering Analysis (EA19-001), to expand the scope of the investigation to include the Tier-one supplier and any manufacturers who installed the subject ACU in production vehicles. Additional information is available with the closing resume available at (see Associated Documents).The ODI complaints cited above can be viewed at under the following ODI identification numbers: 10781050, 10849839, 11099038, 11080341.

What 2011 Hyundai Sonata owners say
Most recent owner complaints, unedited.
I purchased fgis car from a used car dealership, for over $6,000.00 , which is not a ton of money, but plenty enough to not have instant issues. Since my purchase in june 30, 2026, i have already had all of these issues occur. There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil. The exhaust has stron smell of gasoline. My steering wheel has a loud clinking noise everytime I go over a speed bump on pull into my driveway. Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too. I checked to see if any of my issues are covered by a recall warranty, because they all are recalled items for my car year, make, and model, but apparently Hyunfai is only covering these dangerous recall items for ul to 10 years. These items shkuld be covered longer, because my carfax states that at least one of these recalled items had already been changed in 2018, and is already broken again!! Hyundai should have covered these extreamly high wear out car parts for a longer period of time, or for the life of the vehicle, if every 5 years your replacing a $1000.00 part, not including labor, like the (HPFP) I was quoted by auto zone for over that price point!! "Ridiculous"! Another item is the air bag cover on the driver side windows area, of the body frame it is loose and keeps un-clipping, i am afraid that it is going to possibly just go off and kill me or something!! Very disappointed right now, that i cannot get any of these recalled items replaced by the manufacturer!!
The clock spring went bad causing failure of horn and all buttons on the steering wheel including cruise control. It also caused the airbag light to illuminate.
The vehicle’s airbag warning light is illuminated. The steering wheel also makes a clicking noise, which appears related to an internal clock spring/coil connector failure. This defect may prevent the driver airbag from deploying properly in a crash, creating a serious safety risk. I contacted O’Brien Hyundai of Normal on 4/23/2026 and was denied repair assistance solely due to vehicle mileage. The vehicle has been well maintained, and this issue involves a critical safety component that should not fail under normal use. I am submitting this complaint due to concerns about airbag system failure and occupant safety.
UNKNOWN - I noticed DASHBOARD crack over time and the AIR BAG light remain on at all times. The AIR BAG light on the passenger side shows OFF. The entire dashboard is cracked. I fear that I can no longer drive my car distances due to air bag issue. I did not report the issues to a dealer yet, I was waiting until next oil change time. I do not know the date that it started.
There was no accident .Airbag light on the dash, on the driver side, remains on at all times. The airbag indicator on the passenger side says off. Dashboard has completely cracked, both sides and the center. Unknown incidents- I don’t know of any incidents.
The contact owns a 2011 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the driver's air bag warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a failed air bag clock spring. The contact was informed that the driver's air bag clock spring needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer; however, the contact was informed that the repair was not covered under recall. The contact had received an unknown recall notification previously for the air bag. The contact was informed that he was nine days late for the coverage of the failure. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the repair was not covered under repair. The failure mileage was unknown.
To Whom It May Concern, Subject: Formal Complaint – 2011 Hyundai Sonata GLS Tail Light Meltdown / Fire Hazard Date: August 3, 2025 I am writing to formally report a serious safety issue with my 2011 Hyundai Sonata GLS, specifically concerning the tail light assembly, which has melted and poses a potential fire hazard and traffic safety risk. Approximately a year and a half ago, I noticed melting in the tail light housing and took the vehicle to a Hyundai dealership to address the issue. At that time, the car had approximately 208,000 miles. Despite the obvious manufacturing defect and safety implications, the dealership refused to repair or inspect the issue without charging a $275 inspection fee, stating the vehicle was out of warranty. I believe this to be an unfair and irresponsible business practice. Tail light assemblies should not melt under normal use, and such a defect could lead to: Electrical fires Brake light failure (increasing the risk of rear-end collisions) Potential traffic citations for inoperative brake lights Damage to other vehicles or individuals I have already notified Hyundai Motor Corporation about this issue, placing them on notice that should any damages or incidents occur as a result of this defect, they may be held liable. This is not a minor cosmetic issue but a major safety defect, and I strongly urge the federal safety agency to investigate whether this is an isolated issue or part of a wider trend affecting Hyundai and Kia vehicles. If so, a safety recall may be warranted. I also intend to report this situation to the Indiana Attorney General's Office as a matter of consumer protection and product safety. I have been backwards and forwards with the Hyundai Corporation Via and Emails...... I look forward to a prompt response. Please!
Air bag light is not coming on at all.
Dashboard has large cracks all over it including where the passenger air bag is located. I am concerned about the pieces of plastic flying if the air bag deploys. Also concerned that the cracks could release the air bag at any time, even during normal driving. Dealer only suggested getting a dashboard cover, but that would negate the purpose of the air bag. My research showed that there are many other cases of the happening with Hyundai Sonata's 2011-2014.
