NHTSA Complaint #11604817 — 2022 HYUNDAI PALISADE

In April 2022, we purchased a new 2022 Hyundai Palisade from a dealership due to persistent issues with our previous Hyundai Santa Fe, which had ongoing engine problems and recalls. After multiple unsuccessful repairs and software updates on the Santa Fe, we decided to trade it in for the Palisade. Since the purchase, the Palisade has undergone over ten warranty-related repairs. In early 2023, an oil consumption test revealed significant warranty concerns, leading the dealership to keep the vehicle for additional diagnostics. This process lasted nine months and included a full engine replacement. During this time, my husband filed a complaint with Hyundai Corporate, seeking a lemon law buyback or an equivalent trade-in. Hyundai Corporate denied our request, stating that we did not qualify under the lemon law and refusing to buy back or offer a fair trade-in for the vehicle. In June 2024, after nearly a year of repairs, we retrieved the vehicle, only to experience severe issues shortly afterward. The Palisade began jerking and shaking on the highway, and the check engine light came on. The dealership identified a faulty mass air flow sensor and ordered parts for its repair. They assured us it was safe to drive until the repair was completed. However, the next day, the vehicle displayed the same issues. A diagnostic at Auto Zone revealed problems with both the air flow sensor and the fuel injector, indicating unsafe driving conditions. We returned the vehicle to Hyundai College Station, where we received a loaner car while they conducted repairs. During this period, we were informed of a "computer digital data hack" that prevented the dealership from providing documentation of the services performed. When we picked up the Palisade, we were told that only the mass air flow sensor had been repaired, with no work done on the fuel injector or other issues. Currently our vehicle exhibited engine defaults and the engine light came on. It is at Principle Hyundai for repairs
