Other Fuel System Problems of Hyundai Tucson - part 1

I was on the highway on the way to work when my car started stalling. Every time I pressed the gas to give it some power, it would not go anyway where. After getting it towed to get looked at some of the fuel injectors failed and were misfiring. The warning message about ‘check engine’ popped up 2 minutes before it happened. This is the third time now in less than 6 months.

While driving the car stalled and then the engine shutdown, caused by a misfired fuel injector. Myself and the passengers in the car were minorly safe, as this incident occurred while driving through the yellowstone national park; having to pull over on the side of the road with no shoulder. The woody smith Hyundai dealership in idaho falls confirmed that the feul injectors had misfired, and then replaced them. Prior to the failure, there was no warning until the car was actively stalling and failing (battery light and check engine light came on).

I was driving on the highway going 65 mph and scared when the engine started clicking and shaking a tiny bit. Plus it was slowing down no matter what I did. Well in a 4 lane highway. There was no engine light, no previous issues. The car drove great until this issue. I had the car only 3 months. Now I am afraid to drive it because I had seen theres an engine recall online for my car. Once I saw the recalls I tried calling alot of my local Hyundai dealer ships and they denied me because of the mileage. When I bought the car it was at 180 mileage. At this point I am not sure what to do with the car, I am hoping it can get fixed.

I became aware of a technical service bulletin that Hyundai published in Jan 2025 acknowledging that many vehicles (of which mine is one) have a faulty fuel injector and it will fail. Hyundai elected to not issue a recall on this issue so the public has no idea they are driving vehicles that are just awaiting for a malfunction in their engine. It appears the reason Hyundai is doing this is because fuel injectors are only covered on the manufacturer’s limited 5-year 60,000-mile warranty so they are hoping the faulty injectors last long enough to get beyond that point and customers don’t know the injectors were even faulty to begin with (because tsbs are not public knowledge). Hyundai can then charge for full repairs and omit admittance that the injectors were faulty and blame it on wear and tear. Mine failed beyond 60,000 miles and I am in this predicament. I imagine most customers with 2022 vehicles have not driven as much as me and haven’t had this come up. It seemed like something I should inform someone about. Do with this what you wish.

Unknown -a catalytic converter clogged after being installed - only 14 months following installation, causing rough and unsafe acceleration, inability to shift gears properly, and need to drive with hazards on. It is clear that there is an issue with the engine/exhaust and system in this vehicle. Additionally, the car needs oil added regularly and seems to be burning it, as indicated by low level.

On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward with brake applied at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive. ".

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching service campaign t1b. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - failure to update software: the dealership failed to perform the mandatory ecm/tcm software integration (campaign t1b) during engine swap, which is required to prevent the exact stalling I am now experiencing. - dismissal of warning lights (code p0456): one day after the engine replacement was “completed,” I returned to the dealership because the check engine light illuminated with code p0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - mechanical negligence (coolant leak): post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

I purchased this 2022 Tucson limited Hyundai new. It has 25,000 miles on it. The car check engine light came on and a power reduction began along with shaking of the car. I was able to clear the intersection safely. I was able to turn into a safe spot and shut down the car. It was towed to the dealer who then informed me that it was an injector know issue for this year and would be covered under the 5 year warranty. However, as this is a engine/powertrain problem, it should be covered on the 100,000/ten year warranty. A TSB (23-FL-002h-1) alert had already been issued, but not a recall. Many owners have reported having this problem repeatedly, as a safety issue and a known mfg defect. When is the government going to step up and demand a real fix be done before someone is killed? owner are current left fighting with the dealers over the warranty limits or taking legal action. If you google this problem, you can find out the national level of this problem, from accidents which caused fires or accidents from power loss. My car is still at the dealer waiting on parts. Its time to force a recall! I will be demanding that it is covered for the 10 year warranty period and considering taking action under the lemon laws. If the government fails to act on this soon, than they are just as libel as the manufacturer. Your immediate attention to this issues is requested.

Approximately one month ago I had a high pressure fuel pump installed in my 2018 Hyundai Tucson. While driving on the highway, about ten minutes from home, my car suddenly burst into flames. There were no warning lights in the cockpit. There was no smoke in the cabin. Another motorist flagged me down. I got out of the vehicle just in time for it to become fully engulfed in flame. It burned down on the highway. Police and fire responded. Insurance is investigating. If I was inside the vehicle, I would have certainly died.

When braking my 2022 Hyundai Tucson to come to a stop, the vehicle continues to accelerate. I have to release the brake and re-apply the brake to fix the acceleration problem. I check the internet on this problem. They internet says it is a software problem. The vehicle shows no code and the dealer says they don't have a problem. The dealer has not check for the problem since there is no code. No warning lamps or messages show up on dash. This happened 4 times in the last few months. Latest date was 4-4-2026.

I just got an oil change and the oil was completely gone although there was no leak found. Not even a week later my oil is low again. There is smoke coming from the back pipes and the gas is burning out quickly. I just purchased the car last year.

Car is a gas hybrid (not plugin). 3 occurrences over the last couple of months. Car emits a warning sound and a message on the dash says "check hybrid system. Stop safely". Basically right after this message the car starts losing power and stops. Doesn't matter if on freeway or not. You need to find a place to pull over or you stop traffic wherever you are. Looks like hybrid battery is completely drained. Can not be re-created. Dealer has it now for the 3rd time. Dealer in the past have not been able to find cause/cure since this issue is not posting any errors to the onboard diagnostic system. Temporary 'fix' is to power off car, and power back on. Looks like this is a 'known' issue though as its being reported by quite a few people online.

On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the recall notification process and handling of this matter should be reviewed further due to the serious safety risk involved.

Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.

High pressure fuel injectors went out.

This vehicle has a considerate amount of oil dilution problems. I have had this vehicle taken in for service several times due to gasoline mixed into the engine oil. Again on March 6 2026 for the 4th time now the vehicle has a check engine light extreme hesitation with an almost stopping jerking motion due to dilution problems. Multiple dealerships claim there is nothing wrong with the car. . There is a distinct gasoline smell in the engine oil. The vehicle at times is almost unsafe to drive due to the hesitation and halting it does on its own. Every time a dealership is contacted my problem is dismissed. There is a burning smell due to the oil gas dilution issue. The car reaches higher temperatures than it should. And now the Hyundai dealership is making me wait almost a month again to have the problem looked at again which then puts me as the driver in an unsafe situation to drive a vehicle with such hesitation and fire risk. If they dismiss this oil and gas mix again and do not repair the car it could seize my engine or maybe possibly even cause fire damage.

This car has major oil consumption that affects the engine and catalytic converter. This can cause engine damage and stalls in driving that affect safety on the roads because the car doesn't accelerate properly. There were no warning signals to indicate this being a problem with the car, especially at purchase. This car will get an oil change and in less than a week, the oil is gone and bone dry.

While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. The vehicle was later inspected by an authorized dealership, which confirmed severe internal engine damage, including cylinder damage and engine misfire requiring major repair or replacement. No clear root cause has been provided. There were no prior warning signs or symptoms before the incident. Warning signs prior to failure: none observed. The vehicle is available for inspection upon request. Dealer confirmation: yes. Manufacturer inspection: unknown.

Oil extremely hot and burnt to oil stick. Running really hot. Dangerous possible fire hazard.

Low oil, burnt oil on dip stick, engine running dangerous hot, lights on on dash, engine knocking.

Engine light #2 gdi injector at 60,900 miles been repaired but not under warranty out at 60,000 miles.

Repeat repair timeline – loss of acceleration vehicle: 2022 Hyundai Tucson hybrid blue issue: intermittent loss of acceleration from a complete stop (safety concern) occurrence 1 approx. Date: 12/2025 mileage: ~ 48000 description: vehicle failed to accelerate immediately after a complete stop. Pressed accelerator and experienced a noticeable delay before the vehicle moved. No warning lights. Turned on and off. Restarted normal. Action taken: no service visit at this time. Occurrence 2 approx. Date: 01/2025 mileage: 12/2025 description: same issue occurred again from a complete stop. Delay in acceleration while entering traffic. No dashboard warnings. Action taken: issue noted for future service visit. Occurrence 3 (reported to dealership) date: 50,000-mile service 01/14/2025 mileage: ~50,000 miles description: loss of acceleration from a stop occurred multiple times prior to this visit. I informed the dealership that this was a very dangerous safety issue. Dealership response: vehicle was serviced as part of the 50,000-mile maintenance. Dealership stated they could not find anything wrong. No specific repair or explanation provided. Outcome: issue was not resolved. Occurrence 4 (post-service) date: January 28, 2026 mileage: ~55,999 miles description: after coming to a complete stop, I pressed the accelerator and the vehicle did not respond for several seconds. No warning lights or alerts. This occurred after the dealership stated no issue was found. This condition has resulted in a dangerous delay while entering traffic and creates an immediate and ongoing safety risk to the myself and young children passengers, and surrounding vehicles. The defect involves a loss of acceleration / loss of motive power and has occurred repeatedly without warning. I am formally requesting escalation beyond the dealership level, full documentation of this safety defect, and a permanent corrective resolution. It is not safe.

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.

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 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.

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.

Component: engine/powertrain/electrical system incident description: I am reporting a recurring, life-threatening "loss of motive power" (dead pedal) in a 2024 Hyundai Tucson (alabama-built). On multiple occasions, the vehicle has failed to respond to throttle input during high-risk maneuvers, specifically while merging into 45+ mph traffic. The vehicle "chugs" and stalls, refusing to exceed 15 mph despite full accelerator depression. This defect leaves the vehicle and its occupants stranded and defenseless in the path of oncoming high-speed traffic. Technical context: this vehicle is currently subject to NHTSA recall 23v-526 (Hyundai campaign 246) for electronic controller damage that can cause "can communication disruptions. " I believe the "dead pedal" failure is a direct result of these communication disruptions between the engine and transmission control modules. Furthermore, Hyundai has issued TSB #24-at-001h-1 for "hesitation when accelerating," yet the authorized dealer (ed voyles Hyundai) has been unable to remedy the defect after 84 cumulative days out of service. Safety risk: this is not a convenience issue; it is a critical safety failure. The unpredictable nature of the power loss makes it impossible to safely judge gaps in traffic. The vehicle effectively becomes a stationary object on active roadways without warning. Manufacturer response: the manufacturer has been formally notified via certified legal counsel. Despite 79 consecutive days in the current repair attempt (since Jan 16, 2026), the manufacturer has failed to provide a fix or acknowledge the severity of the safety risk. An informal third-party evaluator attempted to dismiss the claim despite the vehicle's documented inability to maintain motive power. We are requesting that NHTSA investigate the adequacy of recall 23v-526 and TSB #24-at-001h-1, as these measures have failed to resolve this life-threatening "dead pedal" condition in my vehicle.

On January 7, 2026, shortly after delivery of a used 2015 Hyundai Tucson (VIN [xxx] ), the vehicle experienced immediate mechanical failure while being driven, resulting in sudden loss of power and drivability. Multiple warning lights illuminated on the dashboard at the time of failure. The vehicle became disabled and left the occupants stranded roadside in fairhope, alabama. The exact component that failed is unknown at this time. The failure appears related to the engine, powertrain, fuel/propulsion, and/or electrical systems. The vehicle was not operable after the incident. On January 8, 2026, the selling dealership (sandy sansing Nissan, pensacola, florida) towed the vehicle back to their dealership. The vehicle has remained in the dealership’s possession since that date and is available for inspection upon request. This sudden failure created a significant safety risk due to loss of propulsion while in traffic and exposure to roadside hazards. The problem has not been independently repaired or evaluated by the consumer. No manufacturer inspection has occurred to the consumer’s knowledge. The dealer has not provided a diagnostic report or repair findings. No warning lights or symptoms were disclosed prior to delivery. The failure occurred almost immediately after delivery. The vehicle was sold and delivered by a licensed dealership. The sale is currently in dispute because the vehicle became disabled almost immediately after delivery due to this safety-related failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All four cylinders misfired in my car while driving causing the catalytic converter and all four fuel injectors to need to be replaced. My car suddenly stopped driving in a rural area with only a few minutes of warning when the engine light came on. I was not even able to drive to a nearby shoulder. I was stranded on the side of the road in 5 degree weather until a tow truck could come.

My 2024 sel hybrid has a very annoying acceleration delay after a full or partial stop. The delay has occurred many times. It is present no matter which mode the car is on. It is not a matter of slow acceleration, but a 1-2 second delay of anything happening after I press the pedal. This could be a safety issue when you're at a stop sign and you need to proceed and you can't go.

#1. This vehicle uses a lot of oil !!! it burns through it like crazy I have to check the oil every other day. #2. When I come to a stop while driving and give it gas to take off it wont go !!!!! it hesitates and when it does go it lunges forward!! this is a huge manufacturer problem not a buyer problem. The engine is junk. ! 3. I’ve called numerous places to get help. This car needs to be recalled. This is a huge safety violation. It doesn’t wanna go when you give it gas and when it does, it lunges forward that can cause a huge accident on the highways. This car was made in china. It is junk. I’ve called to get help with this issue and no one wants to help. Nobody returns my calls and I’ll Hyundai wants to do is it even more money out of me when this isn’t my fault the car is junk. For safety concerns I would like someone to call me at [xxx]. This car needs to be recalled and my daughter has one. It’s doing the same thing except hers is a lot worse. Hers is further advance where it’s actually stalling in the middle of the road while driving huge safety violation. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

My car is burning oil. I have returned multiple times to have it serviced and checked for leaks, but no leaks have been found. Before reaching the recommended 3,000-mile oil change interval, the oil level drops below the minimum mark on the dipstick. In addition, my engine has started making a knocking noise, which is very concerning.
