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.

September 15, 2024 while driving with cruise control set at 65mpg, the 2022 Hyundai Tucson began shaking and experienced an abrupt loss of power. I released the cruise control, and the vehicle wouldn't accelerate over 45 mph without shaking severely. September 16, 2024 car was inspected by a dealership and determined it was the 4th cylinder fuel injector; mileage on the vehicle was 45,314. Repairs were made per a TSB P030X. January 27, 2025, while driving with cruise control at 60mph, the same thing happened again. Managed to get the car to another dealership, only to find out all 4 fuel injectors needed to be replaced; this time with a TSB 25-FL-001H kit; mileage was 50181. Approximately March 11, 2025 car started the same issue, only this time there was no abrupt shaking or loss of power, however very strong smell of fumes. I refused to park the car in my garage, and immediately called Hyundai USA with all of this information from the start of these issues until current. The car was then taken to another dealership with mileage at 51332, only a difference of 1151 miles since last issue. This time all of the fuel injector seals are melted. Hyundai USA refuses to do anything about it. It was verified with the service technician this last time, that raw fuel was leaking onto the hot engine and could have resulted in the car catching on fire. The first two times this happened, I was out of state while being broken down.

(1) [XXX] (14,568 mi): The vehicle had been running normally. My wife was about to switch lanes at an intersection when the vehicle started to shake and vibrate. The entire dashboard lit up and the vehicle quickly died. She tried restarting it and the engine wouldn’t turn over. Anytime there was an attempt to restart, there was a potent odor of gasoline. The car died in the middle of the road. It would sort of start but then it wouldn't move and would just shake and smell of gas. After many minutes of trying to start the vehicle, barely got power but was able to pull to side of road around other cars. Hyundai app reported codes: P030300 and P217800. Had car towed to local dealer. Picked the car up and next day spoke to the service manager who indicated there was a 20%-25% chance this would reoccur. He said there was nothing he could do as Hyundai would only cover the cost for the existing issue. The paperwork from the dealer shows it was a P0303 for cylinder 3 misfire and system too rich caused by leaking fuel injector for cylinder 3 (low pressure). [XXX] (14,702 mi) I was driving the car, in middle of an intersection and the vehicle started to vibrate and all lights on dash lit up (check engine, battery, etc.) and smell of gasoline. Car hesitated and wouldn't move. Died in intersection. Had to have 2 people help push me as I was dead in middle of road with people beeping and passing me. Got to side of road and couldn't get vehicle to start. No error codes on app this time, but all symptoms were exactly the same. Called for tow, different dealership due to location. Dealership indicated they would return it to us safe, but because of Hyundai policies, they can only work on the affected items. This is well documented by Hyundai owners of this problem and going by what the service manager of the first location told me, this is common to spread to other injectors. THIS IS UNSAFE! TWICE IN MIDDLE OF INTERSECTIONS! TWO MORE INJECTORS! SOMEONE IS GOING TO GET HURT! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFO

-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.

We have had an issue with the engine and the oil pressure warning light. Our car seems to also be leaking gas and our repair people have asked us to come in every 1500 miles because there seems to be an issue they do not know how to remedy. We are worried that this is going to get worse and could act up on the highway and result in injury or death. My wife is a 2nd grade teacher and drive this car on the highway everyday.
