Injector problem

[Ed24]

I have a 2015 3.8 RWD with approximately 65000 miles. A couple of weeks ago my car developed a very strong gas odor and ran like it was firing on a couple of cylinders. Hyundai Roadside Assistance had my car towed to Eastern Shore Hyundai in Daphne, AL. They told me that one of the injectors was stuck open and that it needed replacing. I had them replace all six injectors and picked the car up. The car ran fine - for 25 miles and started misfiring and the strong gas smell came back. The car was towed back to the dealer and they said one of the the new o rings they installed split. They replaced the o ring and the car ran fine for 25 mile and repeated the misfiring and strong gas smell. It was towed in again and my last talk with indicated they have no idea what is causing the problem. Have any of you experienced this same problem?

Third week with no solution to problem. Latest update from dealer indicates they still don't have a clue.

Update report. The dealer discovered that one of the six new injectors was deformed and failed. They replaced it and returned the car to me and it seems to be running fine.
