2022 HYUNDAI TUCSON Complaints

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.

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.

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.

All four GDI injectors failed resulting in the car completely stopping on the highway.

January 2023-driving down the road and the car was shaking and wouldn’t give much gas when pressing the accelerator. When we got it towed to the dealer, they said it was the fuel injector. July 2024-driving on a major highway, car starting doing the same thing and stopped on the highway I pulled to the shoulder. I was not safe at all. The tow truck took over 2 hours to come. It was a hot summer day. When it finally got towed it was confirmed it was a second fuel injector. November 2025-driving and the car did the same thing, currently at the dealership and it’s the 3rd fuel injector. I’ve never felt so unsafe in a car. It only has 30k miles on it. I don’t drive on the highway because I get anxiety about it stopping again. There’s another fuel injector that “needs” to fail to complete all 4.

Fuel injectors failed after 4 years of having the car. This led to misfiring, shaking of car, and complete shut down of car within 10 seconds of starting the vehicle.

While driving the engine would not turn on and we were stuck EV MODE. Lost power , had to pull off to shoulder of road and had to turn vehicle off and back on in order for car to move.

Two separate times over the last year I’ve had a fuel injector go bad after using the auto start feature in semi colder temperatures. I’m not sure if the auto start has something to do with it but seems to be a cold weather issue.
