general problems of the 2022 Hyundai Tucson - part 1

Check engine light appeared, car began shaking and struggling to accelerate. Independent mechanic and oreileys test stated cylinder 3 misfirw. Dealership stated gdi fuel injectors were leaking and is a known issue in several 2022 Hyundai tuscon and needed to be replaced.

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.

The contact owns a 2022 Hyundai Tucson. The contact stated that while stopped, the vehicle hesitated to respond, with the check engine warning light illuminated. The contact stated that while the vehicle was parked, it was shaking unexpectedly with a misfire coming from the engine, and the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the fuel injector had failed and needed to be replaced. The vehicle was repaired. The contact later stated that while driving at an undisclosed speed, the vehicle lost motive power, with the check engine warning light illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the cylinders had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

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.

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.

The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, there was a misfire in the engine, and the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with engine cylinder failures. The contact was informed that the cylinders needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 55,000.

I am dealing with this issue where I am getting fuel injector issue and getting cylinder 3 misfire and air fuel imbalance code. It comes and goes. I spent 1500 bucks flushing fuel system and replacing spark plugs and coil. But the issue is still there! I changed the battery and got it to dealership they said they could find the issue. I was on freeway going southbound near exit 34 when the car starts shaking and I lost acceleration.

While operating the vehicle, the engine shut down. Complete loss of power. Engine would restart, stall and then not restart. Vehicle immobile. Vehicle towed to dealership since could not be driven. Strong smell of gasoline.

The contact owned a 2022 Hyundai Tucson. The contact stated that while the vehicle was parked, the contact's neighbor knocked on the contact's residential door and informed the contact that the contact's vehicle was on fire. The contact stated that when she went outside, the contact noticed that the entire front of the vehicle was on fire. The fire department was called, and the fire department extinguished the fire. A fire report was filed. The contact stated that the vehicle was burned all the way to the rear seat of the vehicle. The fire burned another vehicle that was parked in the contractor's yard. In addition, the contact stated that the fire burned a good portion of the contact's residential yard. The vehicle was towed to a local tow yard. The vehicle was condemned a total loss by the insurance company. The fire inspector informed the contact that the fire started in the engine near the battery. The manufacturer was not made aware of the failure. The failure mileage was approximately 76,500.

The contact's wife owns a 2022 Hyundai Tucson. The contact stated that his wife reported that the vehicle shuddered significantly and failed to exceed 30 mph while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors were leaking, and the dealer determined that the fuel injectors needed to be replaced. The dealer informed the contact that the manufacturer had redesigned the fuel injectors due to the known failure. The dealer informed the contact that the repair could not be covered under the extended warranty because the vehicle had exceeded the required mileage. The contact was informed that parts needed to be ordered to repair the vehicle. The vehicle had not yet been repaired. The contact related the failure to TSB number: 22-FL-002h. The manufacturer was notified of the failure, and a case was filed; however, no assistance had been provided. The failure mileage was approximately 65,000.

I am submitting this complaint regarding an ongoing and dangerous issue with my 2022 Hyundai Tucson involving repeated fuel injector failures that have caused the vehicle to stall and lose power while driving, without any prior warning indicators. The first incident occurred in October 2023, at approximately 16,000 miles, when the car suddenly died while I was driving. There were no warning lights or signs of a problem before the stall occurred. The vehicle had to be towed to the dealership, where they replaced two fuel injectors. Just two weeks later, the same issue happened again—the car died while driving and was towed back to the dealership. The remaining injectors were then replaced. Unfortunately, this problem has continued. In November 2024, at around 26,000 miles, the vehicle again stalled while driving, with no warning, due to another fuel injector failure ( more failed injectors). Most recently, on October 18, 2025, with 31,000 miles on the odometer, my Tucson lost power and died while I was merging onto an interstate—once again with no warning or alert of any kind. I am still waiting for confirmation of how many injectors have failed this time. This is an extremely serious safety hazard. Losing engine power unexpectedly, especially while merging into highway traffic, puts both the driver and others on the road at significant risk of a collision or serious injury. Despite multiple occurrences, Hyundai has not identified the root cause of the injector failures and continues only to replace the faulty parts, which clearly does not resolve the underlying issue. It is unacceptable that a relatively new vehicle would experience repeated fuel system failures of this nature, and it is clear that there is a systemic defect affecting safety and reliability. I urge the NHTSA to investigate this issue to determine whether other Hyundai Tucson owners are experiencing similar failures and whether a recall or safety action is warranted.

2022 Tucson (nx4, alabama built) 2. 5l engine experienced a catastrophic failure leading to Hyundai dealer diagnosis that "cylinder #3 is not contributing properly," which requires a full engine replacement. The vehicle is currently located at home and is available for inspection upon request. The engine scuffing has resulted in a severe loss of power contribution from cylinder #3, leading to potential for sudden engine stall or complete loss of motive power while driving. If the engine seizes or stalls at highway speeds or during a critical maneuver (e. G. , merging onto a freeway or turning across traffic), it creates an unreasonable risk of a rear-end collision or a catastrophic accident, endangering both the driver and others on the road. Furthermore, the internal mechanical failure creates a significant fire risk due to potential oil leakage onto hot exhaust components. The problem has been confirmed by Hyundai service center in el paso, texas and three independent service centers in arizona and texas. All four assessments concluded that the vehicle requires a full engine replacement due to severe internal damage. Inspected by Hyundai service center in el paso, TX. Despite confirming failure, Hyundai refuses to provide critical diagnostic data (power balance test, endoscopic inspection, dtcs) and the determined root cause. This refusal hinders warranty transparency. The check engine light (cel) did not illuminate. Symptoms appeared late September 2025 at approximately 88,000 miles (audible engine noise/scuffing, rough idle, significant power loss). This failure at non-typical mileage demonstrates a severe internal defect and a safety system malfunction (failure of the ecu/cel to adequately warn the driver). Note: dashcam video documentation of the engine failure symptoms (audible noise and power loss) is available and can be presented to investigators upon request.

Hyundai has a known issue with gdi fuel injectors. Car begins to shake and lose power and eventually will stall due to cylinder misfire caused by defective injectors.

Fuel injector failure. Car was losing power completely when pressing the gas pedal then would suddenly catch and go again. Then go very slowly with little power, almost got into an accident because of the loss of acceleration. They replaced the fuel injectors and it is now happening a second time with the check engine light coming on again. A recall needs to be made! several of the same complaints on here!!!!!!!.

On August 14, 2025, at approximately 12:40 am, my 2022 Hyundai Tucson limited suddenly stalled while driving and became completely non-functional. The vehicle had about 25,000 miles at the time. This left me stranded on the highway in the middle of the night, creating a serious safety risk for myself and other motorists. The vehicle was towed to a Hyundai dealership. The dealer claimed the issue was caused by “carbon buildup” and stated that the problem would only be considered “repaired” if I paid for a fuel injection cleaning and fuel induction decarb service (about $500). These services are not listed in the Hyundai factory maintenance schedule, and no diagnostic evidence (photos, test results, or measurements) was provided to support the claim. Because the stall made the vehicle inoperable, I believe this should have been handled under warranty. Instead, I was pressured to pay for optional services in order to have the safety issue resolved. Safety risk: the vehicle stalled without warning at highway speed, placing myself and others at risk of collision. Based on the dealerhip this needed to be serviced every 20k miles and Hyundai deosnot recommend to consumers for some reason. .

While driving, I accelerated to merge onto the highway. The check engine light flashed a few times and the engine started wobbling like it was misfiring. I have also been having a parasitic drain on my auxiliary batter that makes the car not open to my key fob that I know works. The dealership told me it was bad fuel, but they “tested the fuel” with no diagnostic report/proof/records, saying that the fuel was bad and had a high concentration of 5% alcohol. They re-did the test and took pictures which shows the fuel is within tolerance but no diagnostic report and are refusing to complete a warranty checkup on my engine/electrical system. Also, the misfires with acceleration due to merging has happened 3 times. From the start back in July 2025 till now.

While driving on highway going 65 mph my car 22 Hyundai Tucson sel dashboard lights turned red and shut off on the highway with no warning, was not able to put in park for 10 minutes. My safety was put at risk, the vehicle stopped mid drive on the highway with other vehicles. Dealership has not fixed or looked at the issue.

My high pressure fuel injectors and spark plug had to be replaced at 72,000 miles. My check engine light came on and the car started vibrating and was not accelerating properly. I spoke to three Hyundai dealership service centers and each of them acknowledged that it was a known issue with 2022 Hyundai Tucsons.

Fuel injectors failure. . . . . Second one in a little over a year. Broke down on major highway. . Towed to hundai in cape girardau as it is under power train warranty. Only to be told that this is not part of the power train even though it is in the engine. Known issue,, last time the mechanic told us it was part of power train. There have been service bulletins on this issue.

Component or system that failed: after a routine oil change at rick case Hyundai of roswell on Saturday, \[insert date], my 2022 Hyundai Tucson began shaking significantly. The dealership later informed me the issue was related to a **malfunction in the fuel injector system**. The vehicle is currently at the dealership and available for inspection upon request. How safety was put at risk: the shaking occurred immediately upon driving away from the dealership and worsened rapidly. I was concerned about losing control of the vehicle orengine stalling while driving, which could pose a danger to myself, passengers, and others on the road. I returned the vehicle immediately to avoid further risk. Reproduced or confirmed by dealer or service center: yes, the problem was confirmed by the dealership (rick case Hyundai of roswell). They diagnosed the issue as being related to fuel injector failure. I am waiting on a written report and confirmation of warranty coverage. Inspected by manufacturer, police, insurance, or others: at this point, the issue has been inspected and diagnosed by the Hyundai dealership. It has not been inspected by police, insurance, or any other outside parties. Warning lamps, messages, or other symptoms before failure: warning lamps, messages, or other symptoms before failure: yes, the check engine light turned on shortly after I noticed the vehicle shaking. The symptoms began **immediately after the oil change**, and the engine light appeared as the shaking worsened. There were no prior warning signs before this incident. This suggests a sudden failure, possibly related to the fuel injection system*, as diagnosed by the dealership.

Cylinder 2 misfires, engine code p0302. Yes, it is available. Engine loses power during acceleration. Yes, Hyundai of anderson (south carolina) no warning or symptoms. Driving great then the engine starting misfiring going down the interstate.

Vehicle has just over 20,000 miles, and all four high-pressure fuel injectors have been diagnosed as “bad”. This is a very common issue reported on the internet for 2022 Hyundai Tucson vehicles. Vehicle misfires and loses power with check engine light.

While merging onto [xxx] in southington, CT, the vehicle would not accelerate past 25 mph which is very dangerous for merging onto an interstate highway. Luckily, my wife was able to safely pull over onto the shoulder. We shut the vehicle off for a minute, restarted it, and have had no problems since. There were no warnings, and no check engine indicator was displayed. I'll contact the dealer this month at a regular maintenance visit. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

1-- fuel injector failed 11/2023 one month to replace it, 2-- fuel injector failed 3/2025 in dealer, 3-- fuel door does not open, replaced by dealer 3/2025.

2022 to Hyundai tuscon now with the third cylinder misfire due to faulty fuel injector. This can be inspected upon request. Upon second occurrence, requested all cylinders be replaced and advised could not do this under warranty. Second filing to NHTSA. This incident put myself and other drivers at risk. I was driving on a highway and the cylinder misfire occurred resulting in check engine light and vehicle going into limp mode and inability to drive more than 30-40 mph. The entire vehicle violently shakes and loses power with this misfire. In the previous occurrences , could not accelerate beyond 20 mph. I could have been rear ended or caused a serious accident on the highway as a result of Hyundai faulty fuel injectors and cylinder misfires. My vehicle has now been seen 3x for the same issue and replaced by dealer. There were no warning signs prior to the failure of the fuel injector resulting in cylinder misfire and loss of power and inability to accelerate. This is a very dangerous faulty component of this year make and model- it is a known issue. Still no recall. I have a "new" car that puts me in danger every 4-6 months when I lose power in my vehicle with no warning or cause except from faulty parts. This faulty part is going to cause serious injuries/accidents if it is not addressed.

Hyundai has a service bulletin for their 12v battery but isn’t notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to ‘stop safely’ with no warning or indication that you’re about to stop moving on a road.

Master cylinder for the brakes went out.

Within the first year of purchase, my power train system has beeb throwing codes. I took it to the dealership where they assured me nothing was wrong. My fuel injectors then gave out. The dealership replaced them and told me “yes these things are faulty and we see it a lot”. After replacing it, they did not 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. I am not experiencing further engine issues which they do not know how to diagnose. My car is a 2022 purchase from the lot. The engine is defective and Hyundai is negligent. They admitted they were aware of the injector issue but didn’t do much to correct this. After corrected, they almost had my car set on fire from fuel pouring on the engine.

The vehicle experienced a malfunction in the ignition or fuel delivery system, specifically a misfire detected in cylinder 2 (dtc p030200). This component has been documented by the manufacturer’s vehicle service center as an issue and may be available for inspection upon request. The misfire caused reduced engine power and hesitation during acceleration, posing a safety risk, particularly while merging onto highways or attempting to pass other vehicles. The issue has been reviewed and addressed by the manufacturer dealer service center twice (presently going in for a third time); however, the problem returned each time after a few weeks, with less than approximately 5,000 additional miles driven. The vehicle has not been inspected by police, insurance representatives, or other parties. The "check engine" warning lamp illuminated when the failure occurred, accompanied by symptoms of rough idling and reduced performance.

Dealership tried to fix vehicle multiple times and failed. Would be considered a lemon but is over 3 years old.

While on a trip my wife started out leaving the hotel as normal. After a minute of so, we lost the ability to accelerate as if the tuscon was not responding to the gas pedal. We were lucky we were in town so we pulled into a gas station and turned off the truck. I thought it might be bad gas so we filled the tank with hi-test and turned off several features that are related to speed control (like tracking the speed limit etc. ) I have noticed at the same time we lost the isg system (idle stop and go). The indication in the owner's manual points to a battery function that detects the battery is fully charged. I used a voltmeter and the battery reads 12. 5v and is charging at 14v. See today's recall for Hyundai vehicles, I think the problem involves a lot more vehicles. If you check the Hyundai forum, there are a lot of complaints on Tucson as well. I hope you take this into consideration when looking into this intergrated charging control issue.

I’ve experienced repeated electrical and mechanical issues with my 2022 Hyundai Tucson hybrid. These include full battery drainage without engine activation (leaving me stranded), multiple warning lights, and recently a heater failure that remains unresolved. I’ve had over 8 service visits in two years, and Hyundai has not responded to my formal letter. A detailed timeline is available if needed.

Check engine light and error message popped up on screen "a possible condition with your engine control system has been detected. A full system check is recommended to be done when convenient. Please contact your local dealership to schedule an appointment. " roughly 46500 miles. Contacted bluelink and they could not help because dealerships were already closed.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! the battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn’t based on the volt meter.

The check hybrid system light came on just after I tried to accelerate from a complete stop and I had no acceleration. I had the accelerator pushed to the floor and I got no response and was not able to accelerate two different times within 5 minutes of one another. I was in traffic unable to accelerate. I took it to the dealer and they were unable to find anything wrong and told me to bring it back if it happened again.
