Tucson

While driving our 2022 Hyundai Tucson Limited with the 2.5L engine and about 39,000 miles, the check engine light suddenly came on. Right away the car started behaving strangely. The throttle response became jerky and uneven, and when idling the engine ran at a higher RPM than normal and sounded off. The vehicle also struggled to accelerate, which made it feel unsafe to drive. Thankfully this happened while we were not on the highway, but if it had occurred while merging or keeping up with traffic, it could have been dangerous. Even in city driving, the jerky response and slower acceleration created risk. What would normally be a safe turn across or into traffic could easily have turned into a slower, delayed turn and a potential accident. When we got home, I checked the code and it said it was a cylinder misfire on cylinder 3. The car had been regularly serviced at the dealer and had never shown signs of this issue before. Based on the symptoms, I suspect it may be related to the fuel injectors, but we haven’t been able to get the vehicle in for inspection because local dealers are backed up. One dealer even told us it was fine to keep driving as long as the check engine light wasn’t blinking, which feels concerning given the way the car is performing.

Car started stalling and misfiring. When I took the vehicle for service they said it was a known issue and they were replacing all 4 fuel injectors. This was my wife’s car. About a year and a half ago the same thing happened to my 2022 Hyundai Tucson N-Line. I have googled around and found many many issues of the same thing happening on 2022 Tucsons.

The contact's wife owns a 2022 Hyundai Tucson. The contact stated that his wife reported that the vehicle shuddered significantly and failed to exceed 30 MPH while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors were leaking, and the dealer determined that the fuel injectors needed to be replaced. The dealer informed the contact that the manufacturer had redesigned the fuel injectors due to the known failure. The dealer informed the contact that the repair could not be covered under the extended warranty because the vehicle had exceeded the required mileage. The contact was informed that parts needed to be ordered to repair the vehicle. The vehicle had not yet been repaired. The contact related the failure to TSB Number: 22-FL-002H. The manufacturer was notified of the failure, and a case was filed; however, no assistance had been provided. The failure mileage was approximately 65,000.

During the early morning of December 23, 2024, at 2am, the vehicle caught fire in the carport of my house. Upon waking up to the noise, I proceeded to evacuate my family from the house due to the amount of smoke inside. The fire damaged approximately one-third of the house. Prior to this incident, the vehicle showed no defects, and all its services were performed by the same Hyundai dealership workshop where I bought the vehicle.

2022 Tucson (NX4, Alabama built) 2.5L Engine experienced a catastrophic failure leading to Hyundai dealer diagnosis that "Cylinder #3 is not contributing properly," which requires a full engine replacement. The vehicle is currently located at home and is available for inspection upon request. The engine scuffing has resulted in a severe loss of power contribution from Cylinder #3, leading to potential for sudden engine stall or complete loss of motive power while driving. If the engine seizes or stalls at highway speeds or during a critical maneuver (e.g., merging onto a freeway or turning across traffic), it creates an unreasonable risk of a rear-end collision or a catastrophic accident, endangering both the driver and others on the road. Furthermore, the internal mechanical failure creates a significant FIRE RISK due to potential oil leakage onto hot exhaust components. The problem has been confirmed by Hyundai Service Center in El Paso, Texas and three independent service centers in Arizona and Texas. All four assessments concluded that the vehicle requires a full engine replacement due to severe internal damage. Inspected by Hyundai Service Center in El Paso, TX. Despite confirming failure, Hyundai refuses to provide critical diagnostic data (Power Balance Test, Endoscopic Inspection, DTCs) and the determined root cause. This refusal hinders warranty transparency. The Check Engine Light (CEL) did not illuminate. Symptoms appeared late September 2025 at approximately 88,000 miles (audible engine noise/scuffing, rough idle, significant power loss). This failure at non-typical mileage demonstrates a severe internal defect and a safety system malfunction (failure of the ECU/CEL to adequately warn the driver). Note: Dashcam video documentation of the engine failure symptoms (audible noise and power loss) is available and can be presented to investigators upon request.

My camera and backup system have not been working correctly since early March of 2024. It has been in service seven times since then, at two different dealers and no service department has been able to fix the problem. There were no warning signs at all, the camera and backup just stopped working. It has been fixed 7 times and each time it has worked leaving the dealership from six through ten days. Occasionally it has gone out, comes back on, but never lasts for more than a day or two. I have notified Hyundai Corporation and have been working with a customer service representative but she has not been able to be terribly helpful. Hyundai tells the service department what parts to order, they do, but the problem has never been fixed successfully. The vehicle has been examined and fixed by two Hyundai service departments. I hit a pole in the West Palm Beach Airport, my camera and back up system were not working, the pole was below the view of the mirrors and it resulted in 2000.00 worth of damage which I paid for out of pocket. The date of this incident was March 23, 2025. I did not call the police as it did not involve another car so technically I guess it was an incident rather than an accident. I do not feel safe driving this car, especially during evening hours.

I just bought this car back in february. It has 50k miles on it. Five minutes after starting it, and in the middle of a busy road, my accelerator suddenly stopped working, my car started shaking, and then it died. My dash lit up and it turns out, it was an issue with the factory fuel injectors.

Driving on Interstate 64 in southern Indiana approximately 70 mph in left lane when engine died without any warning signs. Was able to safely maneuver vehicle to shoulder without incident. Paid to have the vehicle towed 60 miles to Hyundai dealer. Dealer stated engine failure was due to injector issue known by Hyundai as a technical issue was released.
