2023 Hyundai Tucson

The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" We changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

I was on the highway on the way to work when my car started stalling. Every time I pressed the gas to give it some power, it would not go anyway where. after getting it towed to get looked at some of the fuel injectors failed and were misfiring. The warning message about ‘check engine’ popped up 2 minutes before it happened. this is the third time now in less than 6 months.

Sitting at a red light the vehicle seemed to almost stalled then lunged forward about eight feet almost colliding with the vehicle in front of me. To my knowledge the vehicle has not been inspected by the manufacturer nor has the problem been reproduced by a dealer or independent service center. To my knowledge there were no warning lights, messages or symptoms. I am somewhat unfamiliar with this vehicle since I've only owned it for 5 days. I picked it up on 4-25-26.

All four cylinders misfired in my car while driving causing the catalytic converter and all four fuel injectors to need to be replaced. My car suddenly stopped driving in a rural area with only a few minutes of warning when the engine light came on. I was not even able to drive to a nearby shoulder. I was stranded on the side of the road in 5 degree weather until a tow truck could come.

My 2023 Hyundai Tuscon has 36000 miles. Started running rough with a slight noise. First noticed on Wed [XXX]. On Thursday [XXX] I went to start my car and it stalled. Finally after letting it sit a few minutes it started but only to have the SGI light flash yellow and stay yellow for the remainder of the drive. That day I made an appt at my local Hyundai Dealership in Brandon Florida. They kept my car. Fast forward, Monday September 15th I was notified that the car had lost a significant amount of oil. Car was inspected and free of any leaks. Tech stated because of the low oil & oil pressure the battery life was significantly impacted. I would need an oil change & new battery. Upon arriving back I came across an article stating that excessive oil consumption is common among these vehicles and the dealer wasn't even going to notify me of this issue. They were not honest and I want to file a formal complaint knowing that this is well known issue. I feel unsafe driving my children around and am upset that a recall has not been issued to fix this.

Driving on the highway when my car stopped accelerating when pressing down on the gas pedal. It was very risky to be driving on the highway without the ability to accelerate so we put our hazard lights on while we got out the highway ay the nearest exit and parked the car in a nearby parking lot. We were stranded about 100 miles away from home and had to have the car towed back home. Dealership confirmed that it was the fuel injector that was the issue and has been a known common issue for this type of vehicle.

This is the SECOND time the vehicle has lost power and either had the engine die or stopped producing enough power to drive safely. The first time, the engine lost power to the put of not being able to maintain speed on a very busy highway during rush hour, forcing me to pull to the nearest side (left side of road) that had a narrow shoulder next to fastest vehicles. The most recent event (3/25/2025) took place in a parking lot. Engine was VERY rough at idle and when placed in reverse, it died. Could not restart for ~10 minutes, after which time the problem persisted. In both instances a tow truck had to take vehicle to dealership. In both cases the dealer indicated it was the fuel injectors causing the issues. No check engines lights or other dashboard light came on except for an indication to start the vehicle in Neutral. I used the companies app for the vehicle and no error codes came up. This issue resulted in no damage to persons or property, but could have if I wasn't next to shoulder in the first incident.
