Other Fuel System Problems of Hyundai Tucson - part 2

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.

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.

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.

Car engine seized and lost all power going 60mph down the highway at night with my child in the back seat. I have poured quarts and quarts of oil in this vehicle because it burns oil at an alarming rate until it eventually runs dry and the engine seizes. This is extremely dangerous and luckily my child and I were able to drift to the side of the road without harm and injury. Very discouraging that there are thousands of these cars and engines on the road that can literally seize up at any minute. Maintenance was performed and kept up with. The oil pressure light had been flashing when the vehicle turned but was flashing even when oil had just been changed. These engines are dangerous and have people in a financial hard spot. I still owe $16k on a car I can no longer drive and that Hyundai is saying due to owner maintenance will not get an engine replacement. The facebook group Hyundai oil consumption test has thousands of people dealing with the same exact issue on these cars and engines.

My wife was slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the awd likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the edr (event data recorder). The tech first said he didn't even know what that was, then that he checked with all his fellow techs and they didn't know either, then the story changed to the model not having an edr. We politely told him which page in the Hyundai manual he can find it, and he refused to look, as did his boss. Car was transferred to a body shop, and disposition was to total the vehicle. While the body shop was still evaluating the car, we contacted a second dealer, who said they don't have a reader. I inspected the floormats before the car was towed, as that was an initial suspect, but it was locked in and clearly there was no obstruction. She was wearing tennis shoes and doesn't recall ever having an instance of hitting the wrong pedal in any vehicle. She thinks she was only coasting, not even touching the brake yet.

On [xxx], my 2025 Hyundai Tucson hybrid displayed a red dashboard alert instructing me to “stop vehicle and check brake system. ” the vehicle experienced brake system warnings and a loss of power steering, requiring me to pull over. I immediately contacted Hyundai through the bluelink system, and the bluelink operator confirmed that multiple fault codes were visible in Hyundai’s system. I scheduled a Hyundai service appointment at the next available date. On [xxx], before the scheduled service appointment could occur, the vehicle experienced a sudden and total electrical failure while traveling at highway speed (approximately 65 mph). The vehicle lost propulsion and displayed brake system warnings. After reaching the shoulder, the vehicle also lost hazard lights while disabled in heavy rain. The vehicle was towed via Hyundai bluelink to a Hyundai dealership and removed from service. The occupants at the time of the incident included my wife and my minor child. The loss of propulsion, braking warnings, power steering, and hazard lights created a serious risk of a rear-end collision and injury. Due to repeated and escalating safety-related failures involving electrical, braking, and steering systems, I no longer consider the vehicle safe to operate.

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?.

Spark plugs have been replaced twice- fuel injectors cleaned and now I have another misfire in cylinder 3 and have to replace all four fuel injectors.

While driving on the interstate at highway speed, my 2017 Hyundai Tucson lost power without any warning lights or prior symptoms. The vehicle experienced an immediate loss of propulsion while I was traveling in traffic, creating a dangerous situation because surrounding vehicles were also moving at highway speed & I had to quicky maneuver the vehicle to the shoulder with no power. The vehicle had approximately 73,861 miles at the time of the failure. After the incident, the vehicle was taken to a Hyundai dealership and diagnosed with a burned exhaust valve requiring replacement of the cylinder head & valve. The estimated cost of repair provided by the dealership was approximately 7550. The vehicle had no prior warning lights or symptoms before the sudden loss of power. A sudden engine failure resulting in loss of propulsion at highway speed presents a serious safety risk to both the driver and surrounding traffic. This was an extremely dangerous failure.

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.

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.

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 know there is a re-call for my vehicles engine and year with model. I am having serious issues with my vehicle related to the recalls for the same year and model. I feel unsafe driving my vehicle and now I do not know what to do.

My car on the expressway wouldn't go over 40 and this was happening intermittently so my car was unsafe. No check engine light but it was just at the dealership for an oil change. Has. Been an ongoing problem since I bought the car! smells, gets hot!.

All four gdi injectors failed resulting in the car completely stopping on the highway.

Fuel injectors failed after 4 years of having the car. This led to misfiring, shaking of car, and complete shut down of car within 10 seconds of starting the vehicle.

Driving on interstate 64 in southern indiana approximately 70 mph in left lane when engine died without any warning signs. Was able to safely maneuver vehicle to shoulder without incident. Paid to have the vehicle towed 60 miles to Hyundai dealer. Dealer stated engine failure was due to injector issue known by Hyundai as a technical issue was released.

I've taken the vehicle to several mechanics for engine-idling when turning, going up-hill. I've purchased new plugs, lines, engine cleaners, no-one can figure it out. The oil now has engine shavings even though the oil was recently changed. The car broke down today.

As I was driving I was stopped & told my car was on fire. I immediately stopped & hopped out & less than 30 seconds later half of the hood caught heat/fire & flew into the windshield breaking it. At least half the car is burnt to ashes.

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.

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.
