Lemberg Law is investigating numerous consumer complaints about 2022-2024 Hyundai Tucson models with major fuel injector problems. Typically, cars suddenly lose power without warning and stop abruptly, causing or narrowly avoiding a crash. Many owners report fuel injector failures that recur after faulty parts have been replaced. They say that dealerships will only replace an injector when it fails rather than replace the full set when the first set fails. At the same time, complaints quote mechanics at dealerships saying that there is a design flaw, backing up consumer demands that all fuel injectors should be replaced when the first one (or two) fail. However, because there isn’t a recall, dealerships refuse to do this.

What’s the Issue?
Fuel injector problems experienced by owners of 2022-2024 Hyundai Tucson models have been documented across various platforms including Reddit, forums, and in complaints filed with the National Highway Traffic Safety Administration (NHTSA). Typically, drivers report loss of power and acceleration issues, though some say they experience engine misfires that result in rough idling. A common indicator of underlying fuel injector problems is the activation of the check engine light.
Potential causes include the high-pressure fuel system that the 2022 and newer Hyundai Tucson models have. Additionally, discussions within the Hyundai community suggest that there might be inherent design flaws in the fuel injectors of the 2.5L non-turbo engines, leading to premature failures.
Hyundai has not issued a widespread recall specifically addressing fuel injector issues for these model years. However, a technical service bulletin (TSB) has been released to address related problems in the 2022 and 2023 Hyundai Tucson models. TSB 23-FL-002H-1, released in June 2023, discusses and provides diagnostic procedures relating to cylinder misfires caused by leaking fuel injectors.
What Are Owners Experiencing?
Drivers of 2022–2024 Hyundai Tucson models continue to report serious fuel injector failures, many of which often occur multiple times despite part replacements. Many drivers describe their vehicles as suddenly losing power, stalling in traffic, or hesitating dangerously when accelerating — particularly at intersections or on highways.
The owner of a 2022 model from California reported three separate fuel injector failures to the NHTSA. Each time he experienced sluggish acceleration and lurching, with dealership technicians acknowledging the issue but stating it wasn’t covered by warranty or recall. Another 2022 owner, preparing for a long-distance move from Idaho, was advised that further injector failures were likely but wouldn’t be addressed until the car completely stalled. This forced him to pay $840 out of pocket for new injectors.
For some, the issue presents as dangerous hesitation when pulling into traffic, with the vehicle stalling before suddenly lunging forward. A driver from Pennsylvania states that he narrowly avoided being broadsided after his 2024 Tucson failed to accelerate when merging onto a busy roadway, only to surge unexpectedly moments later.
Other NHTSA complaints describe fuel injector failure while driving at highway speeds, leading to sudden power loss without warning lights until after the incident. In every case, owners express frustration that Hyundai has yet to acknowledge the severity of the problem, with dealerships refusing proactive repairs unless the failure has occurred.
Example Complaints
There are a large number of NHTSA complaints for the 2022 model, though not as many for the 2023 and 2024 models. However, that stands to reason since the 2022 model has been on the road for a lot longer.
In November 2024, an owner from Texas filed a complaint that told how his Tucson stalled in the middle of a busy highway with his wife in the vehicle. “The car suddenly stalled while going 75 mph and she was almost killed and got rear-ended. Later we were informed by the dealership that there is an inherent issue with the fuel injection system on these vehicles and the fuel injector has gone bad. These people only replaced the faulty injector. Two months back another injector went bad and then I researched and found this is a bad engineering issue. Now Hyundai is trying to hide behind the veil of Texas Lemon law and is not taking any responsibility or buying back the vehicle. Hyundai forums are full of this problem and many people avoided near-death experiences because of the stall.”
In December 2024, another owner complained that after reporting that the power train system had been throwing codes, the dealership assured him nothing was wrong. Then the fuel injectors failed. “The dealership replaced them and told me, ‘Yes these things are faulty and we see it a lot’.” However, they didn’t seal the fuel injectors, “causing gas to gush out and set my car to smoke. I was ill from inhaling gas fumes for days. They took accountability and said that the injectors were defective in the vehicles and that they would once again fix it.”
While appreciative, the owner went on to say, “The engine is defective and Hyundai is negligent.”
Online Discussion
There are multiple threads on Reddit that discuss Hyundai Tucson fuel injector problems. The owner of a 2022 model asked in mid-2024 if anyone else had experienced issues with fuel injectors needing to be replaced multiple times. “I’ve now had 3 of the 4 go bad since May 27th and each time the car had to be towed to a dealer for replacement. I went on the NHTSA website to report it and there were at least 40 other recent reports but no recall has been issued by Hyundai yet.”
This was one response: “I just talked to the dealer, and corporate would only let them replace the one with the error code. They cleaned the remaining original injector but I’ll probably be back to them within a few weeks for replacement.”
But this is not necessarily what everyone experiences. Another owner adds that all four fuel injectors had been replaced three times! The next step here was to get Hyundai to repurchase the vehicle.
Another 2022 owner said on a different thread, “The mechanic at the dealer told me that the fuel injector has a design flaw. He said he definitely recommends getting a fuel injector cleaning every 40k miles or so.” The mechanic’s explanation was that the way it’s designed, it sprays downward and the area above the sprayer gets buildup due to it not being sprayed and that is what causes it to fail.
2023 Model Year
The owner of a 2023 Tucson said he had been left stranded on the side of the road when the fuel injectors blew the first time. One week after getting it back from the shop, they blew again. As a result, he was investigating lemon law in New York.
Another response states, “The problem is Hyundai only wants us to replace the bad injector. It’s dumb and we’ve all made the complaint that if you have one bad injector and you’re already in there then why not replace all 4? We’ve had a couple already that have come back exactly like yours with the same issue. It’s not a lemon, it’s just stupid practice on Hyundai’s part to not replace all 4 when this occurs.”
Another owner said they replaced two the first time and then four the second time!
2024 Model Year
Nothing much seems to change. The owner of a 2024 model experienced the same problem. The dealership replaced one of the fuel injectors. But a day later, the fault recurred. After 2.5 weeks, they returned his Tucson stating they had swapped out all the injectors. A week later, the issue was recurring again.
