Component or System That Failed: After a routine oil change at Rick Case Hyundai of Roswell on Saturday, \[insert date], my 2022 Hyundai Tucson began shaking significantly. The dealership later informed me the issue was related to a **malfunction in the fuel injector system**. The vehicle is currently at the dealership and available for inspection upon request. How Safety Was Put at Risk: The shaking occurred immediately upon driving away from the dealership and worsened rapidly. I was concerned about losing control of the vehicle orengine stalling while driving, which could pose a danger to myself, passengers, and others on the road. I returned the vehicle immediately to avoid further risk. Reproduced or Confirmed by Dealer or Service Center: Yes, the problem was confirmed by the dealership (Rick Case Hyundai of Roswell). They diagnosed the issue as being related to fuel injector failure. I am waiting on a written report and confirmation of warranty coverage. Inspected by Manufacturer, Police, Insurance, or Others: At this point, the issue has been inspected and diagnosed by the Hyundai dealership. It has not been inspected by police, insurance, or any other outside parties. Warning Lamps, Messages, or Other Symptoms Before Failure: Warning Lamps, Messages, or Other Symptoms Before Failure: Yes, the check engine light turned on shortly after I noticed the vehicle shaking. The symptoms began **immediately after the oil change**, and the engine light appeared as the shaking worsened. There were no prior warning signs before this incident. This suggests a sudden failure, possibly related to the fuel injection system*, as diagnosed by the dealership.

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.

2022 to hyundai tuscon now with the third cylinder misfire due to faulty fuel injector. This can be inspected upon request. Upon second occurrence, requested all cylinders be replaced and advised could not do this under warranty. Second filing to NHTSA. This incident put myself and other drivers at risk. I was driving on a highway and the cylinder misfire occurred resulting in check engine light and vehicle going into limp mode and inability to drive more than 30-40 mph. The entire vehicle violently shakes and loses power with this misfire. In the previous occurrences , could not accelerate beyond 20 mph. I could have been rear ended or caused a serious accident on the highway as a result of Hyundai faulty fuel injectors and cylinder misfires. My vehicle has now been seen 3x for the same issue and replaced by dealer. There were no warning signs prior to the failure of the fuel injector resulting in cylinder misfire and loss of power and inability to accelerate. This is a very dangerous faulty component of this year make and model- it is a known issue. Still no recall. I have a "new" car that puts me in danger every 4-6 months when I lose power in my vehicle with no warning or cause except from faulty parts. This faulty part is going to cause serious injuries/accidents if it is not addressed.

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.

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 vehicle experienced a malfunction in the ignition or fuel delivery system, specifically a misfire detected in cylinder 2 (DTC P030200). This component has been documented by the manufacturer’s vehicle service center as an issue and may be available for inspection upon request. The misfire caused reduced engine power and hesitation during acceleration, posing a safety risk, particularly while merging onto highways or attempting to pass other vehicles. The issue has been reviewed and addressed by the manufacturer dealer service center twice (presently going in for a third time); however, the problem returned each time after a few weeks, with less than approximately 5,000 additional miles driven. The vehicle has not been inspected by police, insurance representatives, or other parties. The "Check Engine" warning lamp illuminated when the failure occurred, accompanied by symptoms of rough idling and reduced performance.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! The battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn’t based on the volt meter.

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.

I had my gps on and it completely stopped working sending me in circles and the voice directing completely stopped. Very dangerous it had me making U-turns at dangerous intersections. I stopped several times put address in again. This has happened several times and it is very dangerous. Also this address is a known gps address not some obscure destination ´ Next twice I have pushed the start button with my foot on the brake and the car would not start. Third try it started.

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.

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.

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.

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.
