Other Fuel System Problems of Hyundai Tucson - part 1

Vehicle fuel injector code p053f84 reading on 9/9/26, this is the second time vehicle was taken to the dealership for the exact same problem, the idle button in orange, and displayed, first visit while vehicle within warranty limits technician stated couldn't find anything wrong, now vehicle is out of warranty and dealership wants $1300 to fix the same issue. Also the engine was hesitating at each occurrence.

The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" we changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

Fuel injector went bad causing vehicle engine to misfire and shake rapidly. Check engine light is on. The vehicle only has 40,000 miles on it. Seems to be a very common concern for this make and model and roughly the same years. Will not accelerate instantly and will surge a bit when it does. Will still shake when the vehicle is idle.

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.

Dealer completed update 9c2 theta 2 emissions update. After update, the car sputters slightly and increased noise is heard from the tailpipe. Customer returned to dealer after driving the car in different temps and noted the above complaint. Dealer verified the complaint but continues to take no responsibility for the fault on the repair receipt by writing condition is “normal” and recommending “customer to allow vehicle to properly warm up for one to three minutes prior to driving. ” the last line of the service record indicates “no problem found at this time. ” a template letter from Hyundai was attached to the repair record. Hyundai may be instructing dealers to not document problems in the service records assumably so they will not be liable for future litigation. It should be noted that owner was previously denied payment on their 2017 Hyundai Tucson due to lack of documentation by the dealer to prove the case with prior class action lawsuit despite years of verbal complaints to the service staff. Dealer may be intentionally not documenting or taking responsibility for systematic failures in the Tucson in service records. This may be on the direction of Hyundai corporate. 2020 Hyundai Tucson continues to sputter periodically during normal driving conditions. Car is parked in an attached garage making a 1 to 3 minute warm-up time-consuming and possibly unsafe. This required warm up should not be considered normal as indicated on the repair record. Hyundai should take responsibility for their shortcomings and allow proper documentation on service records rather than pushing the fault on the owners. As with previous Tucson complaints, the dealer continues to indicate the problems are the result of owner actions not internal failures.

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).

On 6 occasions over the last 2 months when coming to a stop the engine will increase rpm to 1600 forcing much extra brake pressure to stop, forcing me to shutoff the engine. No codes or indicators and the dealer can't duplicate. I mentioned to the dealer that the car will accelerate while holding down the brake thinking that as a clue as to what's wrong and the service tech told me that is normal but as far as I know it isn't normal. I don't know what to do.

Symptoms observed: •severe loss of acceleration / stalling behavior throughout the entire trip •no check engine light illuminated at any time •when pressing the accelerator: otachometer increased (rpms rising) ovehicle speed decreased or failed to increase appropriately •significant delay in acceleration, especially when: omerging onto the interstate opassing other vehicles •cruise control behavior: oseemed to manage acceleration more effectively than manual throttle ohowever, still exhibited slow response when additional acceleration was required •auto start/stop system: osystem automatically disabled itself owould not allow reactivation during the trip safety concern: this condition made it difficult and unsafe •merge into traffic •maintain appropriate highway speeds •execute passing maneuvers dealer visit (near [xxx]): •vehicle was inspected after sitting for a couple of hours •dealer reported no issues found •however, the problem was persistent and clearly present during operation under driving conditions took vehicle to a dealership in raleigh and asked that they look at the fuel injectors. They determined that all 4 injectors were failing and replaced them under warranty. Concerned that Hyundai America has not issued a recall as driving the vehicle with this issue creates a serious safety concern that would lead to injury or loss of life information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

In April 2026 (29,805 miles) I was on an interstate underpass u-turn and when I went to accelerate from the u-turn, the vehicle “revved”, had difficulty accelerating, and appeared to not go into the next gear for a roughly 10 seconds, meaning I was unable to accelerate and get out of the way from oncoming traffic. Traffic slowed and the vehicle suddenly returned to normal (no warning lights appeared) and I drove home cautiously with hazards on. When attempting to leave less than 45 minutes later, the vehicle started, then as I placed it into drive, it began lunging and the check engine light appeared. Because it was running rough and kept lunging, I parked and had it towed to the dealership. The dtc code listed was po30300 (dtc system powertrain and subsystem ems). Per the dealership, fuel injector #3 was bad and needed to be replaced. When I picked up the vehicle, notes stated “ gdi fuel injctr repl (all4)”. I picked up the vehicle after the repair. In August 2026 (30,923 miles), with less than 1,000 miles driven since repair, I started the vehicle and it immediately “died”. I restarted it and the check engine light came on and it began lunging out of my driveway. I also had difficulty getting the vehicle to brake and almost hit our community entrance/exit gate. A notification appeared on my infotainment system stating: “a possible condition with your engine control system has been detected. A full system check is recommended to be done soon. Please contact your local dealership to schedule an appointment”. The dtc codes listed on the Hyundai app were: po30020, po30040, po30010, po30000, and po19185, p217700. (dtc system powertrain and subsystem ems). I had the vehicle towed to the dealership. They didn’t have a loaner vehicle and I canceled my trip. Later, I was notified that “a hose was disconnected and was allowing air to enter the engine”. He stated, “we flushed it out and everything is working now”. I was told I could come pick it up before they closed.

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.
