2018 Hyundai Elantra Transmission Seal Leak - Out of Warranty Repair
My 2018 Hyundai Elantra, diesel, automatic, with 75,000 kilometers, has been out of its 5-year warranty for 11 months. However, it is unacceptable for a car with 75,000 kilometers to leak transmission oil from the seal. The repair center was unable to explain the problem and indicated that the item was defective; however, because the warranty had expired, they refused to replace it. They asked for ₺33,000 from me to replace the defective part. I'm calling out Hyundai, Hyundai Assan, and Hyundai Korea for any loss of life or property damage in a traffic collision caused by this mistake. Hyundai is accountable for all accidents, financial losses, and emotional distress caused by their refusal to stand behind the faulty part.

Attention: Chung Ju-yung, CIO of Hyundai
In November 2023, I purchased a 2018 Hyundai Elantra diesel automatic with 69,000 km, which I was very fond of. However, the vehicle is actively leaking transmission oil from the seal, putting my family's and my safety at risk.
I reported this issue to Hyundai Assan both in writing and by phone. They directed me to Hyundai Coşkun Plaza, a dealership I'm familiar with. The dealership confirmed the transmission oil leak and noted that this malfunction is causing problems with the clutch (flywheel) set and gear shifts.
After Coşkun Plaza verified the issue and reported it to Hyundai Assan, I was quoted a repair cost of approximately $1,000. However, my transmission has never been disassembled before, and all parts are still original factory components.
I'm requesting that the defective part be replaced or repaired without cost to me, given that this appears to be a manufacturing defect in an original part.

If you acted and focused on solutions like you did when responding to this complaint, we would be devoted to Hyundai, but your approach and conversations are not solution-oriented; you are just making things more difficult.
There has been no response from Hyundai regarding my grievance. The brand is not taking responsibility for replacing the faulty product and part. I would like to speak with an authorized person about this matter, focusing on a solution.
