2022 Hyundai Tucson FUEL/PROPULSION SYSTEM

The fuel injectors in the car keep misfiring causing the car to shake while driving, be loud and idle hard. In the past I have already replaced two different fuel injectors and now this is a third one that needs replaced.

We brought our 2022 Hyundai Tucson into our local Hyundai dealership under warranty for Technical Service Bulletin MISFIRE DTC (P030X) – INTERNAL GDI INJECTOR LEAK REPAIR. We were surprised to learn the dealership did not have the parts in stock considering this is a widely known issue and we incurred significant expenses while waiting for the vehicle to be repaired. Expenses incurred: $211.47 for Enterprise car rental (2026 Hyundai Sonata) from 1/19/26 to 1/23/26 $140.00 to have the vehicle towed to the dealership since it could not be driven $18.14 for Uber to local rental car agency Total out-of-pocket expenses: $369.61 All documentation was presented to Hyundai corporate, but we have been waiting 3 weeks and the company has not reimbursed or provided any update. On a related note, to avoid the inconvenience of having to bring our vehicle in again for another known issue, we asked if the current recall on our vehicle could be completed while our car was in the shop for the week, but we were advised that our vehicle did not have any recalls. However, according to NHTSA.gov, there is an existing safety recall that was issued more than 2 months ago on December 19, 2025 (NHTSA Safety Issue ID #25V893000 / Hyundai recall #290). The fact that we were told there were no recalls on our vehicle is unsettling and this experience has us seriously reconsidering if we will be purchasing another Hyundai again.

engine light #2 GDI injector at 60,900 miles been repaired but not under warranty out at 60,000 miles

When getting onto the highway on November 30, 2025, the engine on my 2022 Hyundai Tucson made an odd sound, acceleration was compromised and the check engine light came on. My husband was driving and he safely navigated us off the highway and back to our home via city streets. We were very concerned we were going to break down on the highway or city street during a cold time of year. The next day we had the vehicle towed to a local auto service center and they diagnosed the problem as a failed fuel injector. They stated this was a known issue by Hyundai. The auto service center ordered the fuel injector kit to make the repair, but they were only allowed to repair the failed fuel injector, not all of them. I'm concerned another fuel injector will fail. If Hyundai knows about the fuel injector issue why haven't they issued a recall?

I have had numerous issues with fuel Injectors failing. The first incident was about 30,000 miles. This was fixed by the manufacturer not even 10,000 miles later, I once again had to return the vehicle, to be inspected by the dealership. Instead of replacing all of the fuel injectors at the same time they chose to only replace one. As soon as my car went over the 80,000 mile warranty limit, my fuel injectors went out once more. My mechanic son, has also changed several as well. I had to tow it, 100 miles to the Hyundai dealership, as I live in a rural area. I was told by a young lady, at the dealership, that it was be covered under the engine warranty, which is 100,000 miles. They weren’t even able to look at the car for a week charged me $250 for a diagnosis… After a week 1/2 dealership finally told me it would be over $3000 to repair.. NO! I had to pay to tow it back. I’ve been without a vehicle for five months. When the fuel injectors went out, it also damaged the high-pressure fuel rail, the high pressure fuel pump, and various sensors. This is dangerous, I live in a very rural area. It stopped operating out of the blue. It chugged/bumped a few times, and it was dead. This is inconvenient, and It’s dangerous, especially during the winter time where temperatures reach -20 regularly and no cell phone signals. I believe Hyundai is well aware, of the problem. In fact the service manager had mentioned that the parts were on backorder because apparently they are in quite high demand. No fuel injector should be going out in 15,000 or 20,000 miles, causing systemic failure. Hundai has made no effort to redesign failed parts. It’s quite disheartening, to replace/repair with a new defective part. That is going to go bad, in just a few thousand miles!! Im retired, on a fixed income. I bought new, so I wouldn’t have issues. Paying new prices, to drive junk. I’d just drop it off @ dealers, and walk away.. But the loan, is so upside down that isn’t even possible.

The fuel door would not open, preventing me from refueling the vehicle. I had to purchase a new fuel door actuator and have the vehicle towed to a repair shop, which caused a significant inconvenience.

The fuell door will not open on the vehicle, and I am not able to put gas in the vehicle. Have taken it to a mechanic and he is unsure of what is going on. For a 2022 Vehicle this seems very odd.

Faulty injectors, engine was shaking, sluggish acceleration, possibly fuel mixed into the oil, check engine light on for cylinder misfires.

While driving our 2022 Hyundai Tucson Limited with the 2.5L engine and about 39,000 miles, the check engine light suddenly came on. Right away the car started behaving strangely. The throttle response became jerky and uneven, and when idling the engine ran at a higher RPM than normal and sounded off. The vehicle also struggled to accelerate, which made it feel unsafe to drive. Thankfully this happened while we were not on the highway, but if it had occurred while merging or keeping up with traffic, it could have been dangerous. Even in city driving, the jerky response and slower acceleration created risk. What would normally be a safe turn across or into traffic could easily have turned into a slower, delayed turn and a potential accident. When we got home, I checked the code and it said it was a cylinder misfire on cylinder 3. The car had been regularly serviced at the dealer and had never shown signs of this issue before. Based on the symptoms, I suspect it may be related to the fuel injectors, but we haven’t been able to get the vehicle in for inspection because local dealers are backed up. One dealer even told us it was fine to keep driving as long as the check engine light wasn’t blinking, which feels concerning given the way the car is performing.

Car started stalling and misfiring. When I took the vehicle for service they said it was a known issue and they were replacing all 4 fuel injectors. This was my wife’s car. About a year and a half ago the same thing happened to my 2022 Hyundai Tucson N-Line. I have googled around and found many many issues of the same thing happening on 2022 Tucsons.

I went to fill up the gas and the gas cap door would not open. The gas station attendant tried to help with no luck. I drove to the dealer - the fuel release actuator had failed. Part was replaced under warranty. I am lucky I had enough gas to get to the dealer. Very scary when you can’t put gas in your car!

Two separate times over the last year I’ve had a fuel injector go bad after using the auto start feature in semi colder temperatures. I’m not sure if the auto start has something to do with it but seems to be a cold weather issue.

What component or system failed or malfunctioned, and is it available for inspection upon request? Cylinder 4 fuel injector failed while driving 70 MPH down the highway. The dealer or manufacturer will have the faulty parts for inspection. How was your safety or the safety of others put at risk? Loss of power and acceleration put me and others at risk; I could not go over 40 MPH on the highway, the car was lurching the entire time. Inattentive drivers being the main concern, with low speeds and driving/sitting still on the shoulder of the road. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealership I had it towed to confirmed the injector failed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The manufacturer is aware of the issue. There is a TSB issued that asks the dealer to send the faulty parts back to them. They are fully aware of the issue and are choosing to replace faulty parts with equally faulty parts. The dealer told me the replacement injectors “are not supposed to have the factory defect” but confirmed they are the same parts. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the engine light came on and I lost power/acceleration simultaneously.

August 26, 2024, (and again on 4/10/2025...I will file that complaint separately) I experienced very rough engine performance and I could not throttle or go faster than 20 mph without the engine seriously rattling. In August under warranty a fuel injector was replaced, and now again in April 2025 the same problem again. Twice I was on a major highway but was luck to be able to get off so as not to cause an accident.

Taken car to work, driving down highway check engine light come on with loss of power. Took to dealership reported cylinder number 3 fuel injector was stuck open. Replaced all 4 injectors. Found TSB for it

I’ve already had my fuel injections changed about 20,000 miles again and my car is starting to stall again check engine light on again seems to be same issue now my car is no longer under warranty. I don’t seem this problem on the recall list but this is not a problem I want to have every 20,000 miles.

I just bought this car back in february. It has 50k miles on it. Five minutes after starting it, and in the middle of a busy road, my accelerator suddenly stopped working, my car started shaking, and then it died. My dash lit up and it turns out, it was an issue with the factory fuel injectors.

I am submitting this complaint due to repeated and dangerous fuel injector failures on my 2022 Hyundai Tucson. This is the third time this issue has occurred in less than three years of ownership. •First incident: My vehicle broke down on the side of the road while I was 10 hours away from home in Florida. This left me stranded and required towing and repairs. •Second incident: The fuel injectors failed again, though fortunately closer to my home. •Third and most recent incident: The same issue happened again, this time with my wife driving—a major safety concern. We purchased this vehicle specifically to avoid breakdowns like this and for the safety and reliability it was supposed to provide. This recurring failure is unacceptable for a newer vehicle and poses a significant safety risk to my family and other drivers. Fuel injector failure can lead to stalling in traffic or on highways, increasing the potential for accidents. I urge NHTSA to investigate this matter, as it appears to be a systemic issue with this model and could lead to serious harm if not addressed.

My fuel injectors has been blown and Hyundai will not replace all 4 when one goes out. So I have to keep going back up to the dealership to get it fixed each time. They always blow on the highway. The first time I was doing some distance driving from Columbus, OH to Dayton, OH. Then the other time happened when I was on the highway during rush hour traffic. There were no other warnings before this happens. It just happens and the engine light comes on as the steering will begins to shakes like crazy.

Fuel injectors fail at 26K miles

For the second time I was driving and all of a sudden lost power and couldn’t give it gas to go. I was almost hit from behind both times.

Engine started idling rough, loss of power. Trouble codes show misfiring in Cylinder 4, believed to be from faulty fuel injectors

On May 20, 2025, at approximately 76,100 miles, I attempted to open the fuel filler door on my 2022 Hyundai Tucson and found that it would not release. The car was unlocked and parked, but the fuel door remained stuck. I eventually managed to open it only after a frenzied random sequence of repeatedly pressing the lock and unlock buttons on the key fob while simultaneously pressing on the fuel door. The mechanism finally released after many attempts, but it was inconsistent and unreliable. A second incident occurred on May 26, 2025 at 76,460 miles when I needed to refuel. While I was not stranded, the experience was frustrating and concerning — especially since the vehicle does not appear to have any kind of manual emergency fuel door release. If this issue occurred while low on fuel or far from help, it could lead to a significant inconvenience or hazard. I brought the vehicle to a Hyundai dealership on May 28, 2025 and demonstrated the problem to a Service Advisor. The Advisor that assisted me was unaware of the problem and could not find a recall or Technical Service Bulletin (TSB). Since it is past the 60,000-mile bumper-to-bumper warranty, I was told the issue would not be covered; I would have to pay out of pocket. However, I’ve read about other 2022/2023 Tucson owners experiencing similar failures, suggesting a possible design flaw in the fuel door actuator or latch assembly. I believe this should be reviewed as a potential defect. Consistent failures of a basic refueling mechanism across multiple vehicles should be taken seriously.

While driving home on the freeway in stop-go traffic, the check engine light suddenly came on. At idle and low speed, the engine ran very rough with lots of vibration and acceleration became difficult. I got off the freeway as soon as possible to take surface streets as I felt unsafe continuing to drive on the freeway. The car continued to vibrate significantly. This happened very close to home and I was able to get home but slowly. When the car cooled down I checked the fluid levels - oil was fine and clear but coolant level was low despite a recent service where a coolant flush was performed and the coolant level was at the minimum level indicated by the reservoir. The dealer performed a test and the fuel injector unit for cylinder 3 failed. Apparently there is no observable coolant leak. The car is now awaiting repair under warranty, but the part is not available for 8 weeks. The dealer intends to replace the failed injector when the part arrives.

Fuel injector failure. Vehicle misfired at startup. When attempting to accelerate, vehicle was hesitating and couldn’t. Towed to dealer and they were able to recreate the issue and place code reader on vehicle to find injector problem. Dealer states that Hyundai is revamping all fuel injectors, not just replacing with current supply on faulty injectors. Car will be at dealer for unknown period of time due to nationwide parts supply shortage
