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.

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. It is available for inspection. (Please!)This is the second failing of an engine, fuel or Powertrain issue. The car was in motion and suddenly just lost power. The first time it occurred about a month after purchased brand new in 2022, the car was coming from a stop light into the middle of an intersection. Driver was thankfully able to glide to side of road since it was early morning and had it towed to dealership. Second time it happened approximately 2 1/2 years later May 29, 2025, the car once again lost engine power at an intersection. Driver, again ,was in a fortunate position to glide off road from a right turn lane. If driver had been in left lanes going speed (55) this would not have ended as well. The car would not restart. Car was towed to dealership. The dealership confirmed that this was a known issue and there was a TSB out. However, there are no kits available to fix it at the moment. And we have no time frame for getting our car back and they have not provided a loaner. The vehicle has only been inspected by the Hyundai dealership. There were absolutely NO warnings before either incidents. However, once the car was in possession at the dealership, we received a phone call from Hyundai BlueLink saying we had a Powertrain issue, which did not make sense since our car had been sitting for two weeks unserviced. If this was related to the same issue they were at least two weeks late. Dealership did not confirm Powertrain issue or how anything would be resolved.

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.

NHTSA ODI 11665975

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.

NHTSA ODI 11665720

The safety alert system on the vehicle alerted us five different times that the vehicle needed to be parked and checked immediately due to a Powertrain issue and each time we took it to the dealership because it is still under warranty at 47,984 mi. This last time they have had it for just over 3 weeks and said there are three or four of the same vehicle with the same issue that they are trying to get parts for. This is not coming up as a recall, but it has been an issue with safety because it tells us to immediately Park the vehicle and it loses engine power when accelerating which is very dangerous for navigating traffic. Insurance has not been involved as it is on warranty and there has not been an accident because of this issue yet. Please look into this because we do believe there should be a recall on this model. I know other people who are having the same issue with the same type of vehicle but on the Santa Fe. The issue starts out where they say it's just a gas cap. But then switching out the gas cap doesn't fix the problem.

Without warning the car started misfiring while I was driving around town. It continued and became worse. I was in Wisconsin on vacation with the closest Hyundai dealer over an hour away. Mileage was 62416 and I had the tires replaced two weeks prior to leaving and while there I explained I would be driving from Virginia to Wisconsin and asked they let me know if the vehicle needed any service. I took it to a local shop to see if it was something easily repaired and was told it was probably a fuel injector and I should take it to the dealership as it may be under warranty. So I had to have it towed and rent a car. According to the dealership the warranty for the fuel injectors ended at 60000 miles.

NHTSA ODI 11664808

My car stopped on the street without notice, check engine light came on and won’t moved, no power on acceleration. Was towed to dealership. Next two days, they told me that two fuel injectors were blocked/broke. I searched on internet and that has happened in many vehicles.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? > While driving, the following systems fail and become inoperable sporadically: blind-spot safety system, tire pressure monitoring system, smart cruise control system, lane following assist system, speed limit warning system, shifter system malfunction, infotainment system, HVAC controls and turn signals. How was your safety or the safety of others put at risk? > I lose access to all safety systems and am unable to see anything on my dashboard while every single light flashes on the dash. Being unable to utilize my turn signals is dangerous because I must restart the vehicle for the issue to be resolved. Has the problem been reproduced or confirmed by a dealer or independent service center? > The problems were confirmed - but NOT reproduced by the Hyundai certified service center. They stated that they can see logs of the issues and were unable to diagnose the specific failures without the warning lights being actively present. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? > Yes. It was sold to me as a Certified Pre-Owned vehicle directly from a Hyundai dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? > The warnings and failures appeared at 64,752 miles, which is less than 5,000 miles after the warranty coverage ended. I purchased the vehicle with 64,300 miles. The issues began less than 500 miles after purchase.

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

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

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

In Dec. 2023 my car stopped dead in the middle of the road. After being towed to ABC Hyundai in las Vegas they had to replace a fuel injector and I was told it could occur again On [XXX] the car began sputtering and shaking. When I bought it in I was told it was the fuel injector. I was told that Hyundai no longer changes just the one injector as they did before but now Hyundai has a complete kit. There was none at the dealership so it was ordered on Sat May 17 and told it would be in on Tues May20 but now I'm told it's back ordered. They are supposed to give a loaner but non available. I cannot be without a car as I live alone and need a car. I called corporate customer service today May 22 but the won't get back to me for several days. I was told by dealer service to rent a car and I would get reimbursed but corporate said that it would be at my discretion.

Driving on the freeway on 5/18/2025 my sunroof completely shattered. I was going about 70 mph and the sunroof was closed. It was not a hot day, approx. 73 degrees. The noise was so loud, as if a gun shot went off next to me. Nothing hit it, nothing around us, nothing was hit on my part. As a matter of fact I was driving in the toll lanes so really no other cars were around me. It came out of nowhere. I called the local Hyundai dealer and drove straight there. This was on a Sunday afternoon. Monday morning the service dept called and said it would be a few days before they have any answers. On Tuesday 5/20/25 the service guy called back with answers saying they have no idea why it happened, they will not cover it, something must have hit it and it will be $4000-$8500 and take 3-4 weeks to fix. He suggests I call my insurance company to file a claim! My car is a 2022 Hyundai Tuscan limited with 43,000 miles, I purchased it brand new and have used my sunroof maybe a hand full of times. As you can see in the photo the glass blew out, NOT in, so nothing hit it to cause this to happen.

I purchased a 2022 Hyundai Tucson brand new, expecting it to be a reliable and safe vehicle for many years. Unfortunately, the fuel injectors failed and had to be replaced far too early in the car’s life. What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel injection system failed. The injectors had to be replaced, and the problem persists even after the repair. I believe the issue may still be present and can be made available for inspection if needed. How was your safety or the safety of others put at risk? The vehicle continues to run poorly and unpredictably, which puts me and my family at risk—especially while driving at higher speeds or in heavy traffic. I’m concerned about stalling, power loss, or a potential engine fire due to leaking fuel. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was diagnosed and confirmed by the dealership, and the fuel injectors were replaced. Despite this, the engine still doesn’t perform correctly. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by the dealership during service, but not by police, the manufacturer directly, or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, there were signs of rough idling, engine hesitation, and overall poor performance before the failure. These symptoms started appearing within the first year of ownership. I have since learned that many other owners of 2022 Hyundai Tucsons are experiencing the same issue. I believe this is a widespread defect that poses a safety concern and needs urgent investigation.

My 2022 Hyundai Tuscon is in the shop for a SECOND time due to a bad fuel injector. The first time was 4 months ago. My vehicle's check engine light went on and it went into "limp mode" on a major roadway. (I take all major highways to work.) A vehicle going into "limp mode" on a highway is super dangerous. My check engine light went on once again, and I brought it into the dealership service center. I left it there for 36 hours, only to learn that they did not have the parts on site to do the repairs. I have to bring it BACK for another 24-36 hours for the repair to be completed on a SECOND bad fuel injector. How Hyundai hasn't issued a recall for the fuel injectors yet is appalling.

In December 2024, the engine lost power while driving. We were able to pull over on a busy road, where we were blocking traffic on a curve. We had it towed to the dealership. There was no warning or light indicating any problem. Thankfully we were not on the freeway when this occurred. The Hyundai app said that all systems in the vehicle were normal. The fuel injector was replaced by Hyundai. Now, 4 months later, the check engine light came on. I took it to the dealership, and another fuel injector needed to be replaced. The service manager stated that he requested that all of the fuel injectors be replaced because this is a known issue, but Hyundai denied the request, so they only replaced one fuel injector. I am expecting this to happen again, and I am especially worried that the vehicle could lose power while driving on the freeway. Please note that this vehicle was purchased new, and I have had all the scheduled maintenance performed at the Hyundai dealership.
