    Recall notifications for Hyundai campaign 251 but no remedy available since early 2023. Finally learned a remedy was available, made online appointment with my dealership (Future Hyundai of Concord, Concord, CA) but when I arrived for my appointment, they said they did not have the part. That was April 29, 2024. I was told to follow up in a week, which I did. Part still not available. Followed up several more times to which I have not received any response. I am driving a potentially very dangerous car now awaiting this recall remedy. Last year I waited 5 months for a new Hybrid battery with similar lack of communication and delays.

    - McFarland, WI

    I have had my car serviced twice by the Hyundai dealership for the same exact issue. I believe I was told it was a knock sensor. A refurbished engine ended up being put in. The car is still having the same issues as when I first got it serviced in 2021/2022. My car is sputtering, loses power when accelerating and stalling. My car has always had an oil consumption issue and is causing additional issues with spark plugs.
