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.

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)

NHTSA Complaint On Sunday, March 10th 2024 our 2022 Hyundai Tucson with 2.5L engine started missing in one of the cylinders. It did not disable the vehicle and it ran like that for several blocks until we could pullover to safety. At this time there were no warning lights of any kind. It wasn’t until I turned the car off, checked the oil (which was good), started the car again and did a lap around the parking lot that the check engine light came on. So there were no warnings. We dropped the car off at our local Hyundai service center that night so it could be checked first thing the next day. It turned out that it was a bad spark plug and injector. At that point it was no big deal. We chalked it up to a fluke. We received the car back on Thursday, March 14th with the explanation of what happened and that it was replaced under warranty. There were NO RECOMMENDATIONS made upon pick up. Exactly 2 weeks later on Thursday, March 28th, the car lost all power while traveling 60mph in the middle lane of the interstate. Again, there were no warning or diagnostic lights coming on. It was pure luck that there was minimal traffic and other drivers were paying attention as the car came to a complete stop in the middle of the highway in order to be restarted and it refused to accelerate above 20mph in order to limp to the shoulder and get to safety. Over an hour later and stopping and starting the car in a parking lot, the check engine light finally came on. The engine was running worse this time. The car had to be towed this time to the service center. After being checked out it was another spark plug and a fouled fuel injector. Researching online showed that this is a very common issue with Hyundai fuel injectors between 12,000 and 25,000 miles. There are currently no technical service bulletins or recalls warning owners of this common failure and potentially losing power traveling at high speeds. Research showed there have been 3 collisions caused by this exact issue to date.

First incident: While driving on the highway, my vehicle began to vibrate intensely, jerking, lost acceleration and ultimately was unable to drive. Smelled burning. No warning lights came on- no indication of a problem. I only had time to exit on ramp and car stopped in the middle of traffic. Car had to be towed to dealer. Second incident: I was driving and the vehicle began jerking and vibrating with no acceleration. Smelled burning again. Only after this happened did the engine light appear. I was able to get over to the side of the road. Luckily I wasn’t far from home. Car had to be towed to dealer again Very unsafe and no recall from Hyundai.

New 2022 tucson limited power train stalled, would not accelerate randomly while on the highway in NJ on [XXX]. Had to get to side of the road and put hazards on as was unable to accelerate past 40mph in a 65mph zone. Once turning off the car, the electrical systems reset. It was crazy i only had the car for 200miles. Thank God it was a leased car. Flash forward it occurred twice before hitting 1k miles. Took it to get serviced and service department had no idea and said nothing was found to be the cause after the second time it stalled. Other incident was around 20k miles gas lock latch broke somehow and couldn't open gas tank to put gas in car. Went to 3 dealerships, 2 couldn't see me without an appointment.

This car has 36,000 miles, purchased new and serviced on schedule. The car is at the dealer for the third time since purchase. The first was a fuel injector issue/drivetrain error. The second time was a bad spark plug. The most current issue is another fuel injector. People on the internet have reported similar problems. The dealership has directed us to come get the car, which is unacceptable, because this is an engine error. I spoke to Hyundai Customer Car and they directed me to rent a car at my own cost and to not drive the car.

In the last 4 months my vehicle has had 2 bad fuel injectors. In both instances my check engine light came in while I was driving down the road. The vehicle shuttered and could not accelerate. Luckily both times J was close to home and was able to turn around. This came with no warning. Both times, I had previously driven the car that day with no issues. When I went out for another trip, the vehicle then had an issue. I am concerned the fuel injectors for this vehicle/model may have a defect of some kind, as I have lost two in a very short amount of time. If this happened in a congested area or highway it could absolutely present a safety issue. The first incident occurred when the vehicle had about 59,000 miles on it.

While driving the check engine light comes on and the car loses power and starts running very ruff and almost stalls at times. This is the second time this has happen in 3 months, last time they replaced a fuel injector. I look up the problem and it seams to be common problem with the 2022 Hyundai Tucson.

Vehicle would not accelerate leaving driveway. Was bucking as I went down the street. At end of street when I tried to turn off it stopped as I accelerated and I was almost rear ended. I pulled over there were no warning lights on at all. I pulled out as I wanted to turn around and go home and it would not accelerate again. I was able to make it home. I looked up problem on line and it seems like I am not alone. As it is Sunday going to call dealer tomorrow but not expecting them to take it in soon as most appointments take over 1 month to get. I am very scared to drive my car.

Car intermittently will loose power (shortly after commencement of driving). This will remedy itself by shutting off engine and restarting. This has happened 4 or 5 times within the fist 3,000 miles. This is a vehicle and traffic SAFETY issue that could cause lives!

This Tucson Limited has 3500 miles on it from purchase last September - 2022. Less than 1/2 mile from home and accelerating to about 35mph the engine lost power where speed reduced to about 20mph, acted like air intake was being choked. Did not see any caution lights on the dash. I coasted for 30 feet - luckily the street had no traffic - and the engine began to operate normally. I continued traveling about 2 miles and it happened again but briefly - still on town roads, continued driving and it happened once again climbing a hill. Made it part way up and power came back. Continued driving to destination another 2 miles, parked the car for about 45 minutes, came back, car started normally, drove home without incident. If this occurred on a busy road or highway I'm sure the trip would have ended in an accident. I believe this is a dangerous fault. Car is in for service now and they say the ECU was updated. Hope that corrected the problem as my wife refuses to drive it without some confidence level improvement.

-There are 3 problems. The 1st and most dangerous, is a combo of the engine, transmission, and fuel system. The 2nd is malfunctioning sensors. The 3rd is water leaking in under my glove box onto the floor mat. The car upon 3 different occasions has stopped accelerating in the middle of traffic. 1st: the car would not go past 30mph and it stuttered/ shook. I parked and turned the car off, but 5 minutes later it reset and ran "normal". The 2nd time in Dec 2022, I was on Annapolis Rd.(Maryland) at about 10pm while alone. It would not accelerate past 35mph, the check engine light came on, and the engine/transmission started shaking and stuttering. I was almost rear ended so I pulled over. The next day when I called the dealership, the car had once again reset itself. The dealer brushed me off, said the cars are so computerized that if they couldn't replicate it they couldn't fix it and said they were backed up on appointments. The 3rd time, the car stopped accelerating on the beltway as I was taking my exit home, almost got rear ended, as I was pulling off the exit and trying to pull over the car started producing white smoke and the smell of gas, the engine control system (1st time of these 3 instances) alerted to shut the car down. The gear shift would not work properly while trying to shut it off. It massively leaked gas out of the vehicle and into the oil/ oil filter. While broken down, multiple cars almost ran into it as it had shut down after a major intersection. The car almost exploded/ caught fire. It was towed to an autobody shop to be inspected as I did not trust the dealership. No repairs were made. Only an oil change and new oil filter. There was a random misfire code. But ran normally once reset. There was no damage that he inspected and called it a Lemon. The dealer has the car, and has yet to diagnose it or give me a loaner. All regular maintenance performed and all system checks have come back normal up to this point.

I have a 2022 Hyundai Tucson with about 15k miles on it. I have had it serviced twice for oil changes and the recommended manufacture recommended maintenance. However, I have noticed a SIGNIFICANT loss in power upon acceleration with this vehicle. My new car drives very rough and this is a safety issue due to the fact when entering the interstate, the car will not increase speed as requested putting myself and others on the road in danger. Additionally, simple maneuvers like turning into cross traffic are of concern because the vehicle doesn't respond to acceleration when accelerating from 0mph as well as in stop and go traffic. There are no engine lights or codes that I can visibly notice but even in sport mode the acceleration of the vehicle is not responsive. This is a KNOWN issue at Hyundai as one local dealership offered me a service visit 6 months out because they are so overbooked with these issues. A quick Google search also brought up numerous owners experiencing similar and and escalated issues to include complete engine failure and vehicle overheating. This vehicle needs to be recalled immediately! I experience this loss of power EVERY SINGLE TIME I DRIVE and I don't feel safe driving my new car anymore. I have mentioned this to my dealership and they are going to take a look at it today. Occasionally, the car will also indicate to me that I should keep my hands on the steering wheel when I typically drive with BOTH hands on the steering wheel.

Without any warning indicator my 2022 Hyundai Tucson (11850 miles on car) stalled on the road. I received an alert on my phone from Hyundai, after the car shut down that there was a system failure. Car was towed to Pugi Hyundai dealership (where I purchased in new in Jan. 2022) and after several days I was advised the following: Cause: P0303 Cylinder #3 misfire active. Hyundai technical service Bulletin 23-FL-002H-1 addressed concern. 20DA14R1 Replace 1 GDI fuel injector which includes ((1) injector assey-fuel, (3) combustion seal ring, (1) pipe-high pressure, (4 ) k-Bolt. The dealership and Hyundai Corp. state that until the vehicle breaks down they aren't able to replace the KNOWN defective parts. Therefore, I am left driving a vehicle that WITHOUT warning can stall on the road which is a MAJOR safety risk!!!! This is absolutely not acceptable. This should be a recall! The dealership stated they can replace the remailing 3 fuel injectors for $799.00 pre-tax. I asked what batch of fuel injectors are they using and the Service Manager stated the new and improved. The old batch was discarded!!!! How is this legal??????
