Bad news for Hyundai and Kia in the U.S. – they are facing a class action lawsuit over defective fuel injectors that could cause serious engine failure

Hyundai could be facing legal action after a fault was detected in the fuel injectors of thousands of vehicles manufactured between 2020 and 2024. Despite being the most reliable brand on the market, the models primarily affected are the Hyundai Tucson, Sonata, Santa Fe, and Santa Cruz with a 2.5L GDI non-turbo engine. The malfunctions have caused everything from power loss to unexpected shutdowns on the road, and owners are already organizing to file a class-action lawsuit in the United States.

The defect has left many drivers without a car for weeks, waiting for parts in overcrowded workshops. And the most concerning thing is that, so far, the brand has not given any official response, and it’s not because this is the first recall they’ve issued, because, as we know… Hyundai vehicles spend more time in the shop than on the roads.

What’s going on with Hyundai?

The problem lies in the fuel injectors of vehicles manufactured between 2020 and 2024. This component is responsible for distributing fuel to the engine, but when it fails, the car starts jerking, vibrating, consuming more fuel, or even shutting down while driving, as is the case with these users who have filed the complaint.

And that’s exactly what is happening. On forums, social media, and at authorized workshops, cases are multiplying. Tucson drivers have shared that their cars broke down twice in one week with less than 600 kilometres driven. Others have been left stranded in the middle of the road without warning.

User experiences

One user highlights in forums that their vehicle broke down on the side of the road 965 kilometres from home while on a trip. After taking it to the workshop, the same issue occurred a week later, and now they’re afraid to drive their own car.

Another user reports that their vehicle was in the workshop for over 10 days because there were no spare parts for the fuel injectors, and once they were fixed, they exploded again six weeks later.

How to know if your car is affected

The symptoms are not always obvious, but there are some clear signs that can help you detect the fault:

• Increased fuel consumption: If your car starts using more fuel without you changing your driving style, it could be a warning. The malfunctioning injectors directly affect engine performance, so check it out, and if something seems off, head to the workshop!
• Jerking, vibrations, and unstable idle: Many users report that the engine loses power, jerks, or even shuts off on its own. The idle becomes unstable, and when accelerating, the response is irregular.
• Sudden shutdowns or inability to start: In the most serious cases, the car stops completely or won’t start at all. If this happens on the road, it can be dangerous.

What does Hyundai say?

So far, Hyundai has not issued any statement acknowledging the issue. But workshops already know what’s going on: there are waiting lists for the injectors, and some mechanics confirm that there is an unofficial internal alert. Despite this, those affected are still waiting for a solution, which has not arrived yet, and in the meantime, Hyundai remains silent as if this is their first recall, and they don’t know how to proceed.

What can you do if you have one of these models?

If you drive a Hyundai Tucson (2020–2024), Sonata (2021–2023), Santa Fe (2021–2022), or Santa Cruz (2022) and have noticed any of these symptoms, you may be entitled to compensation. A class-action lawsuit is already being organized that could cover not only the cost of repairs but also the inconvenience, loss of the car’s value, and expenses from being without a vehicle.

How to join the class-action lawsuit

A law firm in the U.S. is collecting cases from those affected. If yours fits, they can contact you without requiring any upfront payment. This is a legal way to claim what you’re entitled to if your car has suffered this fault.

Because this goes beyond a simple mechanical failure. It’s a problem affecting thousands of people who trusted a brand like Hyundai. And when the official response doesn’t come, legal tools become the only way to push and get justice.

So, if you notice that your car isn’t running well, if you’ve already had to take it to the workshop or it has left you stranded for no reason, don’t let it slide. It may be time to file a claim, safety comes first, and Hyundai needs to know that.
