What 364 owners told NHTSA about the 2022 Hyundai Tucson Fuel Cell

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.

The fuel injection system has failed 3 times now causing the car to become slow/sluggish while driving (sudden slow down and lurching). This is a known issue with the car per [XXX] . Each time, the dealer has stated it's a known issue that's not covered by warranty or recall. Each time, the technician has stated that they are unsure why it hasn't been recalled given the prevalence of the issue and the risk of causing an accident.

This 2022 Hyundai Tucson stalled in the middle of a busy highway with my wife in the vehicle. The car suddenyly stalled while going 75mph and she was almost killed and got rear ended. Later we were informed by the dealership that there is a inherent issue with the fuel injection system on these vehicles and the fuel injector has gone bad. These people only replaced the faulty injector. Two months back another injector went bad and then i researched and found this is a bad engineering issue. Now Hyundai is trying to hide behind the veil of Texas Leamon law and is not taking any responsibility or buying back the vehicle. Hyundai forums are full of this problem and many people avoided near death experience because of the stall. I can provide reditt and hyundai forum urls for reference if required.

2 months ago our engine control system warning light came on with a great decrease in speed while driving on the freeway. Brought to Hyundai dealership and was determined that fuel injector 1 misfired and needed replacement. Just last week exact same issue in fuel injector 4 occurred. They admitted issues with 2022 Tuscon injectors but won’t replace until they fail as no recall. This is a massive safety issue as can be driving at a high rate of speed and speed slows immediately.

Running lean on bank 1-Dealership states it is a bad fuel injector on cylinder 1says it is not covered under 100,000 mile warranty. Vehicle currently at 80,000 mile. Radio in vehicle is restarting itself and not shutting off when car is turned off. Radio does not respond to commands such as volume adjustment. Dealership performed software update, but it did not work.

Here we go again. Last time the #3 fuel injector failed while driving on the freeway. Car started shaking and lost acceleration with "check engine" warning light on. Two months later, #2 fuel injector failed while driving on the street with same symptoms as last time. Fortunately, both incidents did not cause any accident but was terrifying. I requested the Hyundai service dealer replace the remaining fuel injectors and again, was informed that Hyundai will only authorize them to replace a defective injector when it's failed. I do not understand Hyundai's logical thinking. Hyundai is fully aware of this issue and have already sent out TSBs. Are they waiting for someone to be in an accident and have major bodily injury caused by defective fuel injectors before taking this matter seriously? I will also address this matter to Hyundai Corporation for a response.

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.

At 37,430 mileage while driving on the interstate our vehicle check engine light came on, shortly after, our vehicle began to shake, and would stall if our RPM fell below 2000, placing us at a serious safety risk of breaking down and causing an accident on the interstate driving 80 mph. We were 290 miles from the nearest Hyundai service department, and managed to make it without breaking down. After inspecting our vehicle, the service department reported that our fuel injector for cylinder two needed replacing, but that it would take 3 business days to order the part, leaving us stranded 1600 miles from home for 6 days in total. On our way back home, at around 38,800 mileage, our check engine light came back on and are car began to shake and stall if our RPM fell below 2000 (same as before) while driving on the interstate. We were 140 miles from the nearest Hyundai service department and still 800 miles from home, leaving us stranded once again. The service department replaced our fuel injector for cylinder 1, and confirmed that this is a known issue for the 2022 Hyundai Tucson, but that Hyundai refuses to replace the fuel injectors until they go bad. This is extremely unsafe, and we still have two fuel injectors that will likely need replacing.

Fuel injector failure while driving at highway speeds to only have the car lose power and becoming a danger while attempting to get off the highway. The fuel injectors are a regular problem with this year, make, and model vehicle. The warning lamps didn’t come on until after loss of power. This is the second time that this has happened. First time was on July 12,2024..

I am dealing with my 3rd clogged fuel injector. My car lost power, starting shaking and wouldn’t accelerate. The engine light went on when it happened, not before. The first time I was on the highway, second time on a major thoroughfare. Not places where I could just pull over. Very scary. I got the first one fixed in 2023. This happened again a year later with a different fuel injector. I just got my car back 2 weeks ago and it is doing it again. I will have it towed but NOT to the dealer this time. They told me it wasn’t a problem with this car, until I called them out on it. Then she said she misunderstood. They are well aware of the problem. I can’t believe the dealer because they aren’t upfront about the problem. They didn’t even give me the paperwork this second time, just a receipt. I when I get this third one fixed, I will never be comfortable driving it

Fuel Injector went out while I was driving to work approximately 5,000 miles later, I was driving home from work and another fuel injector went out. Both times I had to have my car towed to the dealership. They said that was a recall on fuel injector but only could fix the one that went out each time. I am nervous about the next time it goes out. Where will I be and will it be dark and unsafe. I have been a loyal Hyundai car owner. I am now thinking about not purchasing another Hyundai and selling my Tuscon. Customer service and making sure customers are placed in a safe car at all times is very important. Hyundai failed this time.

Fuel injector failure. UTC code PO030300 detected at 27500 miles. Car is shaky and loss of power in idle. Code showing on infortainment screen. Taken to dealership on 9/17/24 with appointment and vehicle was not "diagnosed" until 9/19/24. From loss of power, with children in car it is a safety issue.

I was driving on the highway, and at roughly 55 MPH, the vehicle suddenly lost power; it seemed to regain function momentarily, and then the check engine light went on, and then the vehicle shut down. The vehicle was then rolling. Thankfully I was able to throw hazards on quick enough and the vehicles around me were alert enough not to collide into my vehicle and I was able to get the vehicle over to the shoulder before the lost momentum. The vehicle was then towed to the nearest Hyundai dealership. The dealership informed me that the engine produced code P030200, meaning that the fuel injector on Cylinder 2 had failed. They were able to replace it. The vehicle was at 24188 miles at the time.

I had gone out with my vehicle for an errand, and it was running fine. When I finished, I came back into the vehicle and started it up, and it was shaking tremendously on startup. I turned off the car, started it back on, and it started fine. I got about 300 feet from where I was going, not even ten mph, and the vehicle started shaking the same as minutes before; this time, a check engine light came on. I immediately parked it in a safe spot and called for Roadside Assistance. The dealership that serviced the vehicle informed me the DTC code was P030400, meaning the Fuel Injector for Cylinder 4 had failed. It was luckily replaced promptly. This was the second GDI Injector that had been replaced on the vehicle. Unfortunately, I was told there was a service bulletin on the problem and that the dealership was seeing a lot of this problem. I contacted Hyundai Motors America directly to try proactively to get the remaining two injectors replaced. Still, I was told that because there was no current issue with the injectors, they would be unable to provide any assistance proactively. The vehicle had 35645 miles on the motor when this incident occurred.

I was driving the car home on 8/20/24 at roughly 50 MPH, and I felt this brief bucking motion with the vehicle and a loss of power to the motor. The vehicle did not fully shut down and continued to drive, but it struggled when trying to accelerate. When I got home, I checked the Engine code through MyHyundai, which showed code P219CF0. I reached out to the dealership, leaving multiple voicemails, and after over a week of trying to get them on the phone, I went in person and scheduled an appointment for them to service the vehicle on 8/28. They were not able to see the vehicle until 9/3/24, and after talking with the service manager and reviewing my car history, they were confident it was another injector; he was ordering the parts because he said he didn't have any, and it would take a bit to get them. The car went in on 9/3 as planned, and they called to confirm that Cylinder 1 had an Air-Fuel Ratio imbalance and that the GDI Injector had failed. They had gotten in the injector but did not have the High Press Pipe needed to go along with it, and they would have the pipe in by 9/6. I'm unsure when the pipe arrived, but I called in mid-afternoon on 9/9/24, and they were wrapping up my vehicle and that it would be ready shortly. They performed the standard 34-point inspection on the vehicle and did not find further issues. I reached back out to Hyundai Motors America as I had reached out to them after my second Injector failed; at the time, they were unwilling to replace the remaining injectors proactively. I've now opened my second case with Hyundai Motors America. I am communicating through email now, and I do not believe Hyundai is willing to replace the final fuel injector proactively, even though the vehicle only has one original injector remaining, and based on the bulletin Hyundai has out, the chances are pretty good it will soon fail too.

I had 2 fuel injectors fail on my car within a 3 week period. The car is only 2.5 yrs old and has 48,500mi on it Both instances where when I was on a highway. I had the 1st fuel injector fail on [XXX] and then the 2nd one failed about 3 weeks later on [XXX]. When the 2nd fuel injector failed, I was barely able to drive the car to a safe place to get it towed. I spoke with a Hyundai Corp case worker and I asked why they didn't just replace the remaining 2 fuel injectors. Her response was that they don't replace them when they fail. I now have a 2 year old car that I am afraid to drive because I never know where or when It will leave me stranded.

(2) fuel injectors failed while driving on the highway. This is a know issue with Hyundai, but no recall has been issued. The warranty would have covered it up to 60k miles. My odometer was at 60,232.

NHTSA ODI 11609903

Vehicle suddenly unable to accelerate. Engine shuddered & produced a burning smell until we could safely pull over. Towed to dealership where diagnostics showed faulty fuel injector & they replaced 1 GDI fuel injector per TSB 23-FL-002H-1.

NHTSA ODI 11609412

My service advisor said that another fuel injector would probably go out but it wouldnt be covered under warranty until the car stalled. I am planning to move to Idaho from Texas for college so I spent $840 for new fuel injectors. The engine was pulsating and lost power multiple times. Definitely not what I was expecting to spend on a 2 year old car.

On August 13, 2024, while merging onto the freeway with a driving speed of around 45mph, my car suddenly lost acceleration and started shaking. Seconds later, the "check engine" warning indicator light came on as well. I slowly got off the freeway still without acceleration power and found a safe place to park the car. I contacted Hyundai Roadside Assistance to request a towing service to the Hyundai dealer. I left the car at the dealer overnight and contacted the Service Advisor the next day. The Service Advisor stated that one of the fuel injectors was defective and will be replaced under the warranty. After researching online, defective fuel injectors for my car are a well known issue from the public and Hyundai service departments (2 related TSBs were issued in October 2022 and March 2023). Incredulously, per the Service Advisor, Hyundai will only replace the defective fuel injector one at a time. NHTSA should demand Hyundai to recall all affected vehicles listed in the TSBs to replace all fuel injectors at the same time (defective or not) to prevent another sudden acceleration power loss, which may cause a major traffic accident and great bodily harm.

NHTSA ODI 11608595

Car lost power as I was entering fast traffic area. Acceleration became unresponsive and vehicle came to halt. Would not move there after. Had it occurred a few seconds later I would’ve found myself unable to accelerate in an acceleration lane, or shortly after merging potentially causing injury to myself and others. After getting the issue diagnosed by Hyundai it is apparently a faulty fuel injectors. Researching online, this appears to be a known problem for the 2022 Hyundai Tucson with many claiming they were left stranded on highways, at intersections and during snow fall. In general this issue makes owners fearful to drive their cars. Apparently, this may be caused by a bad batch of injectors but to my knowledge Hyundai only replaces known bad injectors instead of replacing all injectors from the faulty batch. Due to this many experience multiple failures in short periods in short periods of time, increasing risk of safety incidents. My vehicle’s failed at approximately 22k miles but others have reported failures much sooner.

2022 Hyundai Tucson with repeated check engine light and vehicle losing power. Vehicle losing power and inability to exceed speeds of 15 mph with vehicle shaking, knocking, and pedals shaking. No warning that this was going to occur until vehicle becomes unsafe to drive. This has happened twice and one of which was on a high way which created an incredibly unsafe situation. First time diagnostic code was P0303 which was a cylinder 3 misfire and second time - less than 4 months later- diagnostic code was a P0302 cylinder 2 misfire. Hyundai only repairs one injector at a time; refusing to do all 4 despite being a heavily documented issue on this make/model. This would be able to be confirmed by request. This was also confirmed both times by two separate independent service centers. Vehicle has about 25,000 miles on it and has had 3 check engine lights over the past 3 years of owning- it was bought new. The first time was 2 days of owning and it was a bad IAT that resulted in engine stalling once again. All 3 times the car was unable to be driven and created substantial safety concerns with inability to drive.

Twice in 2 months the fuel injectors have went out on my vehicle. It causes the car to start shaking uncontrollably and lose power when hitting the gas almost causing a crash. First injector was injector 3 May 2024 and today 8/10/24 injector 4 went out.

The contact owns a 2022 Hyundai Tucson. The contact stated that while his daughter was driving approximately 65 MPH, the check engine warning light illuminated and the vehicle began to vibrate, lose motive power, and then stalled. The vehicle was towed to the local dealer who diagnosed that cylinder #4 fuel injector had failed. The fuel injector was replaced; however, the same failure occurred with fuel injector #3. The vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 34,219.

NHTSA ODI 11607504

Fuel injectors have failed three times now. Each time they have replaced a single injector and told me the issue is fixed. Once one is fixed, the other goes shortly after. The vehicle enters limp mode with a check engine light, making it extremely dangerous to try and drive the vehicle, especially on entering the highways. The problem has been confirmed by the dealership, and TSB 23-FL-002H-1 shows they are aware of the issue. I have not had it inspected by the manufacturer (other than technicians at the dealership) or any other entity. This issue has happened twice this year, once in March, and this July as well.
