NHTSA Complaint #11645070 — 2017 KIA NIRO

I was driving my car as usual and it began overheating. I took it to the mechanic and they could not find a coolant leak, even though the coolant was all gone. We added more coolant and I was on my way. A few weeks later, the same thing happened. The mechanic said to take it to the dealer because they would need to run a diagnostic. I took it to the dealer and they said there were some new recalls that needed to be repaired that could fix the issue. They did the recalls, I topped off my coolant, and I was on my way. One week later, while picking up my son from school, the engine had a catastrophic failure. This was not only dangerous to me and my kids, but to those around me. The car stopped and refused to start up again mid-driving. I had it towed to the Dealer (Kia of Carson) and they rand diagnostics. A few days later they send me a quote for $10K to replace the engine as well as the muffler system - more than the current market value of the car. The car has just over 70K miles on it, and since I bought it used from Carvana, it was not under Kia's warranty. This is NOT how things should be. They should not be allowed to put vehicles that break down like this and then charge people outrageous amounts for it with no compromise whatsoever. How can the engine be worth more than the whole car? I've talked with Kia customer service and they don't care. I've spent months trying to reason with them, but to no avail. Also, upon research online, there are tens of thousands of Kia Niro (and other kia car model) owners who've had the same problem - overheating that turns into engine failure. This is a systemic problem with a fraudulent company that is destroying the lives of their customers. This experience put my family in danger and has essentially ruined my life since it happened. I hope the NHTSA can do something about this!
