NHTSA Complaint #11578314 — 2013 HYUNDAI SONATA

We were part of the Hyundai Theta claim group. Our car did stop in traffic, luckily my husband was alone, and no one was hurt. It was towed to the dealer. This was October2023. Dealer gave a list of fixes & stated it had nothing to do with theta. We had all recommended maintenance done; as we always do. Roughly 2 months later, Dec., with a full car, it did it again, at a stoplight. We are lucky to be alive. We had it towed to our mechanic. I contacted the Theta claims line. Our mechanic stated oil was still in the filter, but the pistons had blown clear through the engine, which he still has. Hyundai contacted him. He sent pictures. Hyundai denied my claim for timely filing. I have called weekly, followed every instruction. Now they want me to mail a letter. I am a disabled veteran. Look how many recalls they have. They don't mind recalling. They will just deny people. Please help.
