NHTSA Complaint #11664826 — 2018 HYUNDAI TUCSON

I noticed my vehicle was burning through oil, initially indicated by a P011 code, when I called Hyundai they said its often a symptom related to low oil pressure. After oil changes, the code would clear, but it returned multiple times, and on two occasions, the dipstick showed no oil when checked. Despite staying current on oil changes and maintenance, I was dismissed as excessive oil burning being “common” for this engine. After recent recall updates at the dealership, a technician confirmed excessive carbon buildup and that my catalytic converter was beginning to plug. I inquired about an extended warranty offered due to the knock sensor installation but was told it only covers rod bearing failure. Hyundai Corporate echoed this, stating no coverage until catastrophic engine failure occurs, despite the ongoing damage from oil burning and converter clogging. Since my visit to the Hyundai dealership, the symptoms have rapidly escalated. Now, my vehicle is extremely loud and acceleration is poor. It takes a long time to get up to speed, and I worry about driving it as it may result in an accident.
