NHTSA Complaint #11463155 — 2017 HYUNDAI TUCSON

Went in for recalls in feb, not even 2 weeks later car was put into limp mode check engine light flashing. Car was towed to dealership where car was purchased where they said it was due to metal shavings in engine. Car was delivered to Hyundai where they diagnosed it with a faulty knock sensor which had just been replaced not even 2 weeks prior. After getting it towed to another Hyundai dealer for a second opinion was told that bolts from the recall work were cross threaded and broken off into motor causing the metal shavings. Really unclear as to what happened but Hyundai refuses to replace engine warranty was denied. Unsure if Hyundai is aware of the failed engine due to recalls
