2022 Hyundai Tucson ENGINE,FUEL/PROPULSION SYSTEM

I have had 3 fuel injectors go out on my 2022 Hyundai Tucson. When this happened it was completely random and my car would stall and I would be stuck on the side of the road. I have had to miss work due to this happening. They told me that they are only able to replace the broken one each time instead of replace the all 4 while covered under warranty. They also told me that fuel injectors breaking is a common problem in 2022 and newer Tucson's as they are higher pressure systems than previous models. Im worried that this is going to keep happening and I'm going to keep breaking down due to fuel injectors breaking and end up stranded somewhere.

Cylinder 2 misfires, engine code P0302. Yes, it is available. Engine loses power during acceleration. Yes, Hyundai of Anderson (South Carolina) No warning or symptoms. Driving great then the engine starting misfiring going down the interstate.

FUEL INJECTORS FAILURE..... SECOND ONE IN A LITTLE OVER A YEAR. BROKE DOWN ON MAJOR HIGHWAY.. TOWED TO HUNDAI IN CAPE GIRARDAU AS IT IS UNDER POWER TRAIN WARRANTY. ONLY TO BE TOLD THAT THIS IS NOT PART OF THE POWER TRAIN EVEN THOUGH IT IS IN THE ENGINE. KNOWN ISSUE,, LAST TIME THE MECHANIC TOLD US IT WAS PART OF POWER TRAIN. THERE HAVE BEEN SERVICE BULLETINS ON THIS ISSUE.

My high pressure fuel injectors and spark plug had to be replaced at 72,000 miles. My check engine light came on and the car started vibrating and was not accelerating properly. I spoke to three Hyundai dealership service centers and each of them acknowledged that it was a known issue with 2022 Hyundai Tucsons.

I purchased a 2022 Hyundai Tucson brand new, expecting it to be a reliable and safe vehicle for many years. Unfortunately, the fuel injectors failed and had to be replaced far too early in the car’s life. What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel injection system failed. The injectors had to be replaced, and the problem persists even after the repair. I believe the issue may still be present and can be made available for inspection if needed. How was your safety or the safety of others put at risk? The vehicle continues to run poorly and unpredictably, which puts me and my family at risk—especially while driving at higher speeds or in heavy traffic. I’m concerned about stalling, power loss, or a potential engine fire due to leaking fuel. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was diagnosed and confirmed by the dealership, and the fuel injectors were replaced. Despite this, the engine still doesn’t perform correctly. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by the dealership during service, but not by police, the manufacturer directly, or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, there were signs of rough idling, engine hesitation, and overall poor performance before the failure. These symptoms started appearing within the first year of ownership. I have since learned that many other owners of 2022 Hyundai Tucsons are experiencing the same issue. I believe this is a widespread defect that poses a safety concern and needs urgent investigation.

Hyundai has a known issue with GDI fuel injectors. Car begins to shake and lose power and eventually will stall due to cylinder misfire caused by defective injectors.

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.

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.

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.

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.

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 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.

Fuel injector failure on 02/2024. Fuel injector failure on 06/2024. Both times car lost power and started shaking. Hyundai service center will only replace one at a time. Car only has 28k miles.

While driving vehicle, car lost power and show down on highway. Car would not start. Eventually started and sputtered white smoke and the smell of fuel. Car would only go 2 miles and hour. Took to dealership and they said it was the fuel injector pump. No recall has been issued even though several other Hyundai and Genesis i models have recalls for same issue.

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.

On two occasions, both on busy highways traveling at about 65mph the engine just quit running. Very scary but fortunately was able to drift to the side of the road and wait for assistance. The car was towed to the nearest dealer two hours from my home. After the fuel injectors were replaced it was returned to us two weeks later. It only had 9,000 miles on it. This is a very dangerous problem to just stop running with no warning. We could have been hit from behind and killed.

On Friday 05.26.2023 I was driving on the highway and lost all acceleration power to the vehicle and was almost rear ended by a semi. Iwas able to pull off the road but had no power of more than 2 MPH to do so. No warning lights came on, no engine error codes. I had the vehicle towed to the dealership pending review. I have only 1,355 miles on the vehicle. I am afraid to drive this car.

My wife was driving on the parkway north in New Jersey at approximately 65 miles an hour at about 3:45 pm. The car began to lose power, was shaking, and sputtering. Luckily, she was able to pull onto the shoulder and did not get hit by another car or truck. Once she pulled over, she let the car rest for about 10 minutes and started it up again. It hesitated, but started. Once she put it in gear, it stalled. she tried this two other times and it stalled each time. she waited for a tow truck and the care was towed to the dealer. The dealer invoice with repairs is attached.
