2014 Kia Cadenza Continuous knocking and rattling sound since car purchase and now engine started smoking and from what mechanic states, the engine is now blown after just paying off vehicle. There was a Class Act settlement in other Kia models but not for the Cadenza. After researching & finding out this make of car has numerous engine issues, I contacted the Settlement Dept but was told my model car was not included. There are numerous car owners of this same make/model that had same complaint to dealership about the knocking/rattling sounds & from the post of complaints I-€™ve read, this statement to owners countywide was -€œ That-€™s Normal-€. I was shocked to see that others complained of this same issue and also the engine smoking and now not functioning. I would like to file a complaint and/or generate a Class Action Lawsuit because Kia knows that most of their engines are no good, yet they only opted to cover those three cars who-€™s replacement engines were the cheapest. What about those of us with these Cadenzas who are now stuck with a non operating car, especially after working hard for over 6years to pay it off to have the engine blow or head gaskets, when this matter could have been taken care of years ago. My car stopped on February 16, yet I cannot even get a diagnostic appointment until March 21, 2023. I am the second owner of this vehicle purchased 2017, via a trade in of my paid off Kia Sorento so it makes me now wonder if the Kia dealership sold me a vehicle that they knew had a faulty engine and or had already replaced the engine with a remanufactured one? I, along with other Kia Cadenza owners who are or have had engine problems deserve too to have our engines replaced for free. I would like to be contacted to discuss further. If I cannot get assistance from you, then I will look for assistance from the news media in hopes of having them do a story and research on Kia Cadenza owners who too have had engine issues.

The first time anything happened was June 2021. I-€™d only had the vehicle 4 months. We were on the interstate doing 70 mph when there was a loud noise, it jerked back, almost ran us into an 18 wheeler, went into LIMP mode, and left us on the side of the road! Since then, we-€™ve taken it to the Kia dealership in Slidell, La SEVERAL times. They removed 5 pages of codes that came up, said nothing was wrong, then it needed a head gasket until finally they said it needs a $9000 motor!! My Cadenza sat at Kia for over 3 MONTHS before they even looked at it the last time! There have been MANY MANY complaints about the head bolts backing out of these Lamba II 3.3L engines causing a catastrophe. Kia does NOT replace head bolts where inserts are needed. It-€™s an automatic engine replacement. So, now my car is still sitting here in pieces and I cannot get it fixed after paying $9500! Kia needs a recall on the Lamba II engines!! They-€™re dangerous and are going to kill someone!! This isn-€™t the first time Kia has screwed me out of a vehicle! I also had a 2011 Genesis I had to get rid of it wasn-€™t even drivable!! I just want my 2014 Kia Cadenza fixed! Please!

Timing chain tensioner - I started to get a weird rattle when I started the engine. The Kia dealership told me this was a pretty common noise with these engines and not to worry. At 62K miles I took it back in and said something is definitely not right. Well it was the timing chain tensioner. In searching for common issues I found several tsb's reporting the same thing. There is even a technical service bulletin that tells the service department what parts need to be replaced to resolve the issue but there is no investigations or recalls. I still had to pay $2500 to fix it.

When traveling above 25 mph, when I take my foot off the gas pedal in anticipation of an upcoming red traffic signal or on the highway doing 55 or so and seeing traffic coming to a halt ahead, foot off the gas pedal engine keeps going, will not throttle down to near idle.,its as if the gas pedal is stuck. At this point I have to really brake hard to slow the car down, it is dangerous, especially at highway speeds..eventually as the car slows to a crawl the tachometer eventually shows the engine is down to idle speed., and the engine stops pulling on its own..my other issue involves the transmission downshifting to a lower gear and slowing the car down, I have no issues when accelerating, only when I tale my foot off of the accelerator, my Kia dealer cannot duplicate problem even after several visits..I have made a short video of the speedometer and tachometer, and it clearly shows the the car going on its own, while my foot is off the gas pedal.
