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.
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.
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.
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.

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.
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.
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.
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.
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.
Fuel injector failure in fuel injector #2 Hyundai is aware of the issue and has a technical service bulletin. Hyundai only replaced the one fuel injector in November of 2023. July of 2024 failure in fuel injector #3 and they are now replacing all remaining fuel injectors. I have opened up a complaint with corporate Hyundai and I-??m awaiting a response. This failure caused my engine to misfire and a loss in acceleration causing the car to be unsafe to drive.

On 5/27/24, my check engine light came on and the vehicle stayed to shimmy and shake each time I would press on the gas. Had the vehicle towed to the dealer for the #4 fuel injector assembly to be replaced. The same thing happened on 7/16/24 while traveling out of state. I was traveling on a highway and had to keep my emergency flashers on as I tried to coax the car to the next exit. Couldn't go above 25-30 mph. Had vehicle towed to a dealer for the #2 fuel injector assembly to be replaced. Now I am again without a vehicle because on 7/26/24, the same thing happened and I was told it is the #1 fuel injector. I was told by 2 different dealers that this is a known Hyundai Tucson issue but they are only allowed to replace what is coming up with an error code. They are not permitted to change all of the assemblies at one time, even though it would save them and Hyundai Corporate quite a bit of money in the long term. They've now paid to tow my car 3 times, paid workers 3 times the amount of money to replace what could've and should've been done the first time. The dealer was going to try to get the #3 assembly replaced now but there is no guarantee. I'm afraid that I'll have to be back there in another week or two for the last one. This is a serious issue that is not being addressed.
Car lunched from a traveling in traffic 50+ mph to 39 mph and then had to push the pedal to the floor to get it off the highway and on the side during 5 o'clock traffic. Said something about the hybrid battery and went dead. Dealer has had it for 11 days and still can't get it started. Apparently there are THREE batteries in relation to this hybrid and all 3 don't work and never seen this before. Since it's been at the dealer, hyundai has emailed me no less than 3 times that I need to check my lights because my battery is getting low all the while it has been completely dead and they don't even know it. Suffice to say, there was NO WARNING other than a couple of miles prior, my car lunched down to the 39 mph and I lunged on the gas and it picked back up again but it wouldn't do it a 2d time. They obviously still don't know about the vehicle being so dead 2 different tow trucks had to be called because even the tires were locked up. Just still receiving my messages I need to check my lights because my battery (NOT BATTERIES MULTIPLE) is low and it's not low, THEYRE ALL 3 DEAD. I was in a dangerous situation and always felt safe in a 2 yr old car with a full tank and hybrid battery backup and less than. 20k miles. IF EVER FIXED because service may have to send OUT OF STATE I will never buy a hyandai or hybrid again. The entire battery system broke down. Which killed the entire electrical system which now no one knows how to fix
The hybrid system flashes "Check Hybrid System" then the check engine and check HEV lights are illuminated. The vehicle loses power and even with the gas pedal pushed firmly to the floor the engine isn't producing power. This is a safety issue because I've lost power while driving on busy roads and can't clear the intersection, etc. This was reproduced at the dealership and Hyundai is performing a warranty replacement of the "hybrid system". I wanted to make NHTSA aware of the issue because on the Hyundai forums I'm seeing similar reports made. There is an open campaign to update the software for the hybrid system, 9B4, but this software update did not fix the issue.
The first incident was on 5/27/24 when I was traveling about 45 mph. The check engine light came on and the car started to shimmy and shake when I pressed the gas. Error code came up on the screen for P0304, injector #4 was bad. Had the vehicle towed to the closest dealer for warranty repair and was told this is a known issue but no recall has been placed. Then on 7/16/24, same thing happened while traveling out of town. Hyundai app was down so couldn't get an error code. Again had the vehicle towed to a dealer and this code was P0302, #2 injector was bad. Obviously there is a serious issue that needs to be addressed. Need to know if this is a permanent fix or if the other 2 will go out soon. I attached a photo of this report and can also get a copy of the one from May as needed.
A faulty fuel injector caused my Tuscon to lose all acceleration while I was in the passing lane of a 4-lane highway going 75mpg. A check engine light came on and it just bricked itself. I had to glide through 3 lanes almost causing a wreck. We were on a family vacation with our [XXX] daughter in the back seat and we had to wait over 2 hours in the blazing heat for a tow. The dealership said there is a known problem with the fuel injectors in these SUVs. I can't believe there isn't yet a recall for these fuel injectors. I'm concerned someone is going to get hurt because of this very fixable problem. Thanks for the help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
