Owner complaint summary

NHTSA Complaint On Sunday, March 10th 2024 our 2022 Hyundai Tucson with 2.5L engine started missing in one of the cylinders. It did not disable the vehicle and it ran like that for several blocks until we could pullover to safety. At this time there were no warning lights of any kind. It wasn’t until I turned the car off, checked the oil (which was good), started the car again and did a lap around the parking lot that the check engine light came on. So there were no warnings. We dropped the car off at our local Hyundai service center that night so it could be checked first thing the next day. It turned out that it was a bad spark plug and injector. At that point it was no big deal. We chalked it up to a fluke. We received the car back on Thursday, March 14th with the explanation of what happened and that it was replaced under warranty. There were NO RECOMMENDATIONS made upon pick up. Exactly 2 weeks later on Thursday, March 28th, the car lost all power while traveling 60mph in the middle lane of the interstate. Again, there were no warning or diagnostic lights coming on. It was pure luck that there was minimal traffic and other drivers were paying attention as the car came to a complete stop in the middle of the highway in order to be restarted and it refused to accelerate above 20mph in order to limp to the shoulder and get to safety. Over an hour later and stopping and starting the car in a parking lot, the check engine light finally came on. The engine was running worse this time. The car had to be towed this time to the service center. After being checked out it was another spark plug and a fouled fuel injector. Researching online showed that this is a very common issue with Hyundai fuel injectors between 12,000 and 25,000 miles. There are currently no technical service bulletins or recalls warning owners of this common failure and potentially losing power traveling at high speeds. Research showed there have been 3 collisions caused by this exact issue to date.
