NHTSA Complaint #11478282 — 2017 KIA NIRO

I own a 2017 Kia Niro with 48,000 miles on it. In early February 2022, I received a "system overheating" warning on my dashboard. When I pulled over and checked the engine, I noticed that the coolant overflow reservoir was nearly empty. I had the vehicle towed to a dealership (Destination Kia in Albany, NY), who pressure tested the engine but couldn't find any leaks. They returned the vehicle to me, but a day later I got another overheating warning and this time noticed excessive smoke, along with the coolant reservoir once again being drained. I thus brought it to a different dealer (Matthews Kia in Schenectady, NY), who also could not find a leak, but offered to replace the engine. Several months went by without the repair being completed, so I finally went to Matthews last week for a status update. They informed me that they had several Niro's experiencing similar issues, and that Kia Corporate had sent out a "technical service bulletin" to the dealers informing them that this recurring issue in the Niros is due to faulty EGR coolers. I brought the vehicle back to Destination, hoping that as a larger dealer they could complete the repair more quickly. They have since confirmed that the EGR cooler needs replacing, but quoted me $2500 for the repair, stating that it is not covered under warranty. Considering that this problem has recurred in enough Niros to warrant a technical service bulletin from the corporate office, and the obvious safety issues that an overheating vehicle can cause, I argue that Kia should have to send out a recall for this part. It's absurd that I'm being asked to pay $2500 to repair a vehicle with less than 50,000 miles on it, especially considering that this is clearly a recurring issue with this model. I have attached the initial repair records that I received, and will add the $2500 repair order for the EGR cooler once it is completed.
