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

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.

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.

Vehicle started jerking and sputtering. Loss of rapid acceleration. Check engine light came on. Did this at idle and all speeds.

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.

I was merging on the highway when the car bucked and the check engine light came on. I couldn’t drive over 20 mph without the car shaking. I pulled over and had the car towed. The issue was a faulty fuel injector. It was replaced under warranty. I am worried reading online about this problem happening again. My family has owned 4 Hyundais and I’m starting to loose faith in their reliability. This really needs to be recalled.

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)

I was coming back from the mall on the highway doing 50mph and my truck started losing power which it has done before but this time the emergency brake came on and my truck stopped in the middle of the highway on a Saturday. Thank God no one was following me close because that would have caused a bad accident. And also sometimes after I stop at a light or stop sign my brakes harden and I can’t press them down if that makes since and all my needles move back and fourth while the engine is making a noise but the car is still in drive but will not move. I have to hit the button to turn the car off and restart it and this has happened to me 3 times already. This is very frustrating and scary

We fist noticed a problem with the car having a hard time accelerating and a hard shift at 25-35 mph back at the end of November. We then got a check engine light that came on that said P013A00 Powertrain. We brought it to the dealership the first week of December and were told that the transmission just needed an update. Upon taking the car home it was better for about a week then the issue came back sporadically. Then on March 20th my wife was driving the car and it would not accelerate past 35 mph while getting onto the interstate. Cars were going by her at 70+MPH as she sat there helplessly pressing the accelerator. Eventually she got the car up to 50 mph but it would not go any faster. We brought it into the dealership that day and once again they said the transmission needed an update. I then contacted Hyundai corporate and submitted a complaint and they started a case for the issue. After the second time at the dealership the car was ok for a week and then started with the same issues. After taking it to several other dealerships they all tell me that it’s a transmission issue that they don’t know how to fix but they change what they say once Hyundai corporate talks with them. Presently the car will have very high RPM and jump forward almost colliding with cars in front. It will also not accelerate such as the peddle is on the floor and the RPMs are high but the car will barely move until it shifts gears and jumps forward.

I was driving on the highway when the engine would not accelerate. I was stuck in a high speed lane and drivers were on my rear bumper. I could not move over and felt helpless. I pulled off at the next exit and the vehicle was sputtering. I made it home at reduced speed. The vehicle would not start the next morning. I had it towed to the nearest dealership. I was contacted days later and informed that the is a bulletin about power loss due to faulty fuel injectors. Many complaint sites are full of the same problems. I now feel unsafe driving the vehicle on trips. I don't want to get stuck in the middle of nowhere. I am a female senior citizen.

On two occasions, immediately after startup, the vehicle has experienced vastly diminished power. Once in November 2023 and once on [XXX]. Both instances were identical. Vehicle could barely move from a stop, even at full throttle. Speed above 25 mph could not be achieved. RPMs exceeded 4500. Vehicle did not stall. No dash lights, warnings or chimes were triggered. Upon shutdown and restart, problem disappeared. Source of failure is unknown. Upon notification, dealer (Gossett, Memphis TN) offered a diagnostic service for $100 with a two month wait for available appointment. Vehicle has had no other issues. Vehicle is accident-free. Vehicle is unmodified and has received no service beyond scheduled oil changes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
