Lost acceleration while driving on the freeway and car started shaking with Check Engine light on. Took the car to the dealer for diagnostic and was informed that #4 injector failed causing the engine to misfire. This was the 3rd fuel injector failing in 5 months. Per my service advisor, Hyundai released an updated TSB (25-FL-001H) in January 2025 with a 4 new fuel injector replacement kit. Unfortunately, this injector kit was so new that I had to drive a service rental car for a week waiting for the kit to arrive. Let's see if these new fuel injectors will last longer than the old ones.
Car was driving fine. Started sputtering and died, unable to restart. No prior warning injectors will fail. Known fuel injector problem with model years found and replaced. Hyundai Tsb 25-fl-001h used.
Fuel injectors failed while driving on parkway. Car lost power(would not go over 25mph) without notice. Not fun driving at 60mph then abrutly go to 25mph on left lane cars behind me nearly hit my car and could have caused a major pileup.There was no warning prior to losing power and check engine lights came on maybe 2 minutes later. Was able to get to right lane and exit parkway to a secure location to have car towed to dealership. Dealership replaced the fuel injectors.
This problem has happened 4 times in the last two months. After about 15 minutes of either moving very slowly, or being parked and idling, the engine does not start when the gas pedal is pressed. The car accelerates as normal since it is in EV mode, giving the driver the impression the car is operating properly. After driving around 1/4 mile the car loses drive power very quickly - full speed to zero in several seconds - because the car is in EV (battery) mode only. This sudden loss of power twice occurred in traffic, which increased the risk of an accident. Fortunately the car was not running at highway speeds and the car was pulled over safely despite the traffic. After the car lost all drive power, the warning -??check hybrid system-?? appeared on the instrument cluster. There were no warning lamps, messages or other symptoms prior to the problem occurring. Twice a dealer was unable to reproduce or confirm this problem. An independent service center also could not reproduce or confirm this problem. The vehicle is available for inspection, but has not been inspected other than the dealer and the service center.

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.
This is the 3rd time that my 2yr old Tuscon failed and had to be towed in a 4 month period. I was at a light and when it turned green, the vehicle barely moved when I pressed on the accelerator. I was only able to drive a few feet and pulled over and had to have it towed again. They are only replacing the fuel injectors as they fail!!
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
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.
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 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.
