Generation Kia

I purchased a Certified Pre-Owned 2015 Kia Sorento with less than 30K miles from Generation Kia in Oct. A month later the engine blew up while I was on the freeway at night in NC and I had it towed to the nearest dealer, who told me a complete lack of maintenance caused engine sludge and a new engine would be needed. However, the NC dealer said the master database had no information that the car was certified. I called Generation Kia who said it was indeed certified but over a week of my repeated inquiries and phone calls has been unable to provide any proof of certification. I spoke with Sales Manager George, Service Manager Luann, and someone in service named Manny. Now they are ignoring me completely and won't return my calls. They know MY FAMILY'S ONLY CAR IS IN A DIFFERENT STATE IN LIMBO AND THEY DON'T CARE. I called Kia Corporate today and gave them the VIN. They don't have records that it's certified either. I was also initially told by Luann in the Generation Service Dept that her manager said to email her my emergency hotel, car rental and Uber receipts and I would be reimbursed, which I did but so far there has been no follow up or refund. I will update this review once I have resolution one way or another. ** For helping me not have a nervous breakdown, I'd like to thank KIA Corporate, who has opened an escalation case for this, and also my employer's attorney service (an awesome benefit), who said the main businesses they sue on behalf of clients are car dealerships. Which I find both funny and sad.
