A viral social media trend can do more than attract views and online attention. In some cases, it can create real problems for vehicle owners across the country. The TikTok trend known as the “Kia Challenge” showed how certain older Hyundai and Kia vehicles could be stolen, triggering a wave of thefts and costly consequences for drivers. Models that had once been ordinary choices for commuters and families suddenly became targets.
The problem drew attention from law enforcement, insurers, automakers, and local communities. Eight models were especially affected by this theft trend, including the Hyundai Elantra, Kia Optima, and Kia Soul. Understanding what happened helps explain how online content can influence crime and why vehicle security features matter when buying or owning a car.

1. Hyundai Elantra
The Hyundai Elantra became one of the most heavily affected vehicles associated with the viral Kia Challenge. Certain older versions lacked an electronic engine immobilizer, a security feature designed to prevent a vehicle from starting without an authorized key.
Social media videos drew attention to this weakness, making eligible vehicles more attractive to thieves. The trend spread rapidly because short videos could be copied, shared, and watched by large audiences.
What began as online content developed into a public safety problem, leaving owners concerned about parking their cars outside homes, workplaces, and apartment buildings.
Some communities reported sharp increases in Hyundai and Kia thefts after the videos gained attention. The Elantra’s popularity also contributed to its exposure.
A vehicle that is widely owned can become a frequent target when thieves learn that certain versions have a security weakness. However, not every Elantra is equally vulnerable.
Equipment varies by model year, trim, and market, and newer vehicles may have stronger factory protections. Supplied figures attribute more than 11,300 thefts to the Elantra during an early 2025 reporting period, placing it at the top of the cited list.
That number should be interpreted alongside the reporting period and source methodology rather than treated as a universal annual total.
Owners should check their vehicle identification number with Hyundai, ask whether a software update or security upgrade is available, and use a visible steering-wheel lock as an additional deterrent where appropriate.

2. Hyundai Sonata
The Hyundai Sonata was another vehicle caught up in the Kia Challenge theft wave. Certain older versions lacked engine immobilizers, allowing criminals to target weaknesses in their starting systems.
Viral videos helped spread awareness of those weaknesses among people who might otherwise never have considered stealing a vehicle of this type.
The Sonata is a midsize sedan commonly used for commuting, family transportation, and everyday errands. Its broad presence on American roads meant that many owners had to consider whether their vehicles included the security equipment needed to resist the theft methods circulating online.
The supplied figures report 9,154 Sonata thefts during the same early 2025 period referenced for the Elantra. This figure indicates the scale of the problem in the cited data, but it should not be confused with a confirmed annual count or a theft rate adjusted for the number of Sonatas on the road.
The viral trend also created problems beyond the loss of individual vehicles. Theft claims can lead to repair expenses, insurance complications, and difficulty finding replacement transportation. In areas with concentrated theft activity, residents may become more cautious about parking older Hyundai and Kia models outdoors.
Sonata owners should confirm the security equipment fitted to their particular vehicle instead of assuming that every model has the same vulnerability.
Hyundai has offered security-related remedies for eligible vehicles, but availability depends on the model and circumstances. Owners should contact an authorized dealer or consult the manufacturer’s official information for guidance.
A steering-wheel lock, secure parking, and prompt reporting of suspicious activity can provide extra protection. These steps do not eliminate risk, but they can make a vehicle a less appealing target.

3. Kia Optima
Every viral trend needs a face, and for the Kia Challenge, the Optima was one of the faces. The supplied data records 6,011 Optima thefts in early 2025, and it names the model as one of the main vehicles featured in the trend.
Why did creators choose it? Visibility matters on social media. A common midsize sedan appears in plenty of neighborhoods, so viewers can find one easily and try what they saw. Popularity turned into vulnerability.
The consequences went far beyond stolen cars. The National Highway Traffic Safety Administration linked at least 14 crashes and eight deaths to the viral clips. Those are real people, not statistics, and they remind us that a trend online can end in tragedy.
Optima owners have options. Settlement information lists 2011 to 2020 Optimas as eligible for the free software upgrade, which is designed to keep the car from starting without its authorized fob or ignition. Book it at your next service visit.
Layer on visible protection, such as a steering wheel lock. And check your insurance, because some owners struggled to find coverage, and Kia has pointed to options through AAA.

4. Kia Soul
Thieves are creatures of habit, and a viral trend gives them a new habit. The Kia Soul, with 4,380 thefts, shows how that works. The supplied information says it was targeted because thieves concentrated on Kia and Hyundai ignition cylinders after the trend took off.
Think of it as tunnel vision. Once videos showed that one part of certain cars could be defeated fast, people stopped paying attention to everything else. The ignition cylinder became the spot everyone knew about.
The Soul is compact, affordable, and easy to park, which means it often sits on streets and in apartment lots overnight. Those are the places where thefts are hardest to stop.
The fix starts with software. The settlement list includes 2020 to 2022 Souls as eligible for the free upgrade, designed to prevent starts without the authorized fob or ignition. Next, add a visible steering wheel lock, an alarm sticker, and a hidden GPS tracker.
Parking choices matter, too. A garage is ideal. A bright, busy spot is the next best choice. Never leave a spare fob inside, and don’t leave valuables on the seat.
A little hassle today is cheaper than replacing a car.

5. Kia Forte
The Kia Forte was included among the models affected by the Kia Challenge because certain versions lacked an engine immobilizer. The supplied information identifies eligible Forte model years from 2015 through 2021 as part of the group targeted during the viral theft wave.
The Forte is a compact car that appeals to drivers seeking practical transportation. Its popularity meant that the online trend could affect many ordinary owners who had no reason to expect their cars would become targets.
A security weakness that might once have attracted limited attention became more widely known as videos circulated across social platforms.
The central lesson is that a vehicle’s theft risk can depend on more than its price or appearance. Security equipment, the popularity of a model, the availability of replacement parts, and the spread of information about vulnerabilities can all affect its appeal to criminals.
Not every Forte from the listed years necessarily has identical equipment, so owners should verify their specific vehicle. Contact Kia or an authorized dealer to check the vehicle identification number and determine whether a software update or other security remedy is available.
Owners should also ask whether the vehicle has an engine immobilizer rather than relying solely on the presence of an alarm. Physical deterrents can provide an additional layer of protection.
A steering-wheel lock is easy to see from outside the car, while secure parking may reduce opportunities for unauthorized access. Owners should also keep doors locked and avoid leaving valuables visible inside.
The Forte’s inclusion in this list reflects its connection to the reported theft trend. It does not mean that every Forte has been stolen or that all model years carry the same level of risk.

6. Kia Sportage
The Kia Sportage joined the group of vehicles affected by the viral theft trend because certain older versions lacked engine immobilizers.
The model is a compact SUV used for commuting, shopping, and family travel, which means the theft problem reached drivers who relied on their vehicles for everyday needs.
As the Kia Challenge spread, online posts drew attention to security weaknesses in eligible Hyundai and Kia models. The resulting theft activity placed pressure on vehicle owners and local authorities.
Some owners became concerned about leaving their SUVs in apartment parking lots, public garages, or on residential streets. The Sportage was identified among the affected models in the supplied information, although no exact theft count was provided for it.
Without a verified count and a clearly defined period, it would be misleading to assign a precise ranking or claim that its theft rate increased by a specific percentage.
Owners should check their Sportage’s model year and equipment with Kia. Some vehicles may qualify for security software updates or other theft-prevention measures, depending on their configuration and eligibility. An authorized dealer can help identify the available options.
Practical precautions matter, too. Use a steering-wheel lock if appropriate, park in a secure location whenever possible, and keep the vehicle’s keys in a safe place. If your SUV has a connected security service, make sure it is activated and that your account information is protected.
The Sportage’s experience highlights how a problem involving a limited group of vehicle configurations can affect public perceptions of an entire model range. Checking the actual equipment fitted to your SUV is more useful than relying on general claims about the brand.

7. Hyundai Tucson
What makes a security flaw go viral? The Hyundai Tucson offers a clear example. The supplied information identifies it as one of the Hyundai models without immobilizers, covering 2016 through 2021, and part of the group whose thefts surged due to the viral exploit.
Three factors came together. First, simplicity, as the method shown in the videos required no specialized training. Second, availability, since compact SUVs like the Tucson are common and easy to find. Third, social media, with TikTok and YouTube making the clips easy to discover and share.
Remove any one ingredient, and the trend might have fizzled. Together, they turned an engineering gap into a nationwide pattern. So what should Tucson owners do? Begin with the dealer. Ask about the anti-theft software upgrade for your model year.
If the car can’t support it, claim reimbursement of up to $300 for approved devices. Steering wheel locks are inexpensive and visible, which makes them a good starting choice.
Consider your parking spot, too. Thieves often operate late at night in quiet places. A garage, a camera, or a bright motion light can change their minds.
And call your insurer to review your theft coverage before you need it.

8. Hyundai Santa Fe
Our final entry, the Hyundai Santa Fe, closes the list. It’s also named among immobilizer-lacking models targeted by the challenge, and it belongs to the group the viral trend affected most.
Its presence shows how wide the problem became. Hyundai and Kia agreed to a settlement worth up to $200 million, covering roughly 9 million vehicles from model years 2011 through 2022, including the Elantra, Santa Fe, and Tucson.
About $145 million is set aside for owners whose cars were stolen or damaged and not covered by insurance. Kia also said it distributed more than 65,000 steering wheel locks.
Three lessons stand out. A security gap can stay quiet for years until a video exposes it. Social media can spread a method faster than any manufacturer can respond. And small protections, such as immobilizers, matter more than most buyers realize.
Shopping used? Ask whether the car has an immobilizer or has received the software upgrade, and let the dealer confirm by VIN.
Already own one of these models? Don’t wait. Get the update, add a lock, and keep your fob close. Trends fade, but the damage from a theft can last long after the video stops trending.
