NHTSA Complaint #11561800 — 2015 KIA CADENZA

The same engine in these 2015 - 2016 Kia Cadenzas is the same engine present in the Kia Sorentos which have been being investigated for early failure, My kia cadenza stalled at 63 miles per hour on route 73 in new jersey and ever since I've been terrified of it, the dealer (Burlington Kia of South Jersey) told me this is common, and they have stingers and most cars with this same 3.3 engine in for the same failure and it just boggles my mind, I was driving and stalled at 68 while cars are flying by me all because of a known failure? Something that is common and known? I looked up what my diagnosis of my engine was when it was towed into the dealer and my searches lit up with the same problems and the same story from others, I'm just more concerned on how this isn't a recall, if it's known the vehicle can smoke overheat and stall while moving why not warn anyone? If I would of known this I could of done something rather then be put in a situation where I bought a $11,000 car with no warranty as it had only 85k miles, and it blows up in less then a year due to something that is known. The only reason I came to find out about how common this is, is because my mechanic (a secondary shop) told me this is very common with these 3.3 Lambda engines, yet kia still fails to let people know.
