I purchased a 2014 Kia Cadenza from San Leandro Kia on 05/16/17 As a Certified Pre-Owned Vehicle. On 02/16/23, my engine started knocking. I took to get an oil change, because I thought that was the problem but was told it was my engine. I couldn’t get an appt w/ Kia dealership where I purchased my car until Tue 03/21/23 Upon calling I was asked my vin# & asked the # of miles. I stated approx 98k. The service rep -[XXX] said oh, you’re right under the mark (100k). I did not drive the car after 02/16 & actually had it towed home from Pep Boys, who suggested I get it towed due to oil showing in the coolant reserve. I recv’d a call from Kia yesterday stating they had to contact corporate for instructions. Today, rep-[XXX] called to say corporate said my coverage ended in April 2019 @60k ml. I adv her that I have my original sales ppwk sticker that was on my vehicle and it states 10yr/100k ml. She stated what corporate says is usually the final answer. I advised I do not agree & how can I contact them? She said there is no way to contact them. I found the # online & cld. I was told the same thing BUT was adv it was denied because I didn’t purchase a CPO-Certified Pre Owned Vehicle! I replied that they then sold me a deceptive description cus my sticker States it’s include it also notes the 10yr/100k warranty which covers me as a 2nd owner & I also registered my vehicle with CarFax as suggested to do once car was purchased as CPO. After researching Kia, I see that there were recalls on three other Kia vehicles, but my model isn’t listed nor was it part of the Class Action Lawsuit, which many other owners of this model also had engine issues of knocking/ticking/ rattling at start-up. I was even more shocked to see that the same complaints I’d made to my Kia dealership when taking car in for service, that “that’s normal”. I just paid off my car, I am under 100kml and wont reach my 10th year until May 2023. This is not right & I want to file a lawsuit. Plz contact me!

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 “ 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.

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 2500.00 TO FIX IT.
