2015 Kia Cadenza

Engine seized. 3.3L Lambda II GDI. This is the 2nd Hyundai/KIA product that the engine has seized on me. Both with bearing failure. Neither on the list of recalled engines. You need to do a more thorough investigation into Hyundai/KIAs engines. The brands share the same power trains across the entire line up for a number of years. This class of engines has been produced for YEARS along with the Theta class of engines that you already forced Hyundai/KIA to recall. This seizure has cost me THOUSANDS and additional THOUSANDS that I am unable to pay. I was forced to do a voluntary surrender of the vehicle due to this repairs! BEFORE completing the suggested maintenance totaling over 5 thousand dollars the service tech should have warned me that the engine wasn't going to last much longer instead of telling me that the repairs were necessary and could be dangerous. The dealer and this company took advantage of me and who knows how many others! NHTSA needs to do something about Hyundai/KIA!

There are thousands of vejicles with a variant of the 3.3L V6 Lambda II GDI Hyundai/KIA class of engines on the road. There are hundreds if not thousands of complaints regarding different variants of this engine throught Hyundai/KIAs line up. All of them with seized engines. There are class action lawsuits in other countries regarding this engine. They have known since before 2015 that these engines were defective! Just like with the Theta class of engines these engines also have bad engine components. The metal that is used is subpar. These engines need to be recalled. Every owner needs a replacement engine. The little people need justice. Every day someone is affected by a Hyundai/KIA product in a major way. $11,000 dollar engine. Every service completed every repair completed every recall completed thousands of dollars invested into this vehicle only to have it fail me. Now I am stuck like many others with a car that I am forced to surrender to my lender because of the negligence of a huge corporation.

At startup I experienced a knock in the engine which seemed to have gone away. I notified the KIA dealership of the issue. The service advisor told me to drive the vehicle in for service. While attempting to drive the vehicle in for service the vehicle TURNED OFF while going 55MPH without any warning at all. KIA diagnosed the vehicle with a failed crank bearing and that it can happen to high mileage vehicles despite imbecile maintenance records. I have read hundreds of complaints regarding the HYUNDAI/KIA 3.3L Lambda II class engines and faliures at various mileage. Prior to this vehicle i owned a 2012 Buick Regal CXL Turbo. When I decided I no longer wanted to invest any money into it it had over 280,000 miles on it. The engine and transmission were still running strong. I believe that the quality of the materials used and the workmanship is below what the standard should be. Also considering all of the problems that this corporation has had with other engines who is to say that these engines are not also defective?

Soft engine block issues causing headboats to pull out and head gasket to fail. Slight movement in temperature gauge and check engine light begin to flash. Sometimes sometime later after stopping at light check engine light came on flashing, Turn car off and restart engine., Car would not move, Turn vehicle off and then back on again. Finally able to get it removed off the highway. Service manager at dealership indicated that this was beginning to be a known issue with this V6 engine and. Occurring with engines over a hundred and fifty thousand miles. This is a documented and known issue with minute of Kia engines. Also consulted with an independent mechanic who acknowledged that this is a known issue with kia engines and recommended, as did the dealer that the engine be replaced.

There’s something drawing the battery AMPS down. This has been an ongoing problem for the last 6 months. Per Kia techs, it was my battery and grounds needed cleaning. Battery changed, techs cleaned all the grounds the problem still exists. I was informed that it was the alternator, new alternator installed. Problem still remains. A new starter installed, problem still exists.

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.

After hearing a ticking sound in my engine, I had it diagnosed by a Kia service department. They said bad lifters and cam shafts had been installed at the factory, and that sometime soon my engine was going to fail and they could say if it would seize or blow up or what, or how this would play out if this happened when I was driving. My car only has 76k miles, and the ticking sound is fairly quiet. Kia refuses to take the safe route and replace my engine. I do not feel safe driving this car.
