NHTSA Complaint #11499188 — 2019 KIA NIRO PHEV

Within the first 6 months of owning our 2019 Kia Plugin Hybrid, we started experiencing a clunk with a lurch when accelerating from a stopped position. The issue became progressively worse over time - increasing in frequency and severity. The car has been to the Kia Lupient dealership in Brooklyn Park, MN multiple times for this issue. At our most recent visit on November 7th, 2022, the service advisor acknowledged that the issue may be due to shipping the vehicle with the wrong transmission fluid. The transmission fluid was replaced with the correct fluid. However, we experienced the issue again on December 2, 2022. Could the wrong fluid have caused permanent damage to the transmission? This Technical Service Bulletin (https://static.nhtsa.gov/odi/tsbs/2020/MC-10174520-0001.pdf) indicates that could be true. We are pursing arbitration with the dealership.
