There are 14 owner-reported engine complaints for the 2014 Kia Cadenzain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2014 Kia Cadenza. The contact stated while driving 70 MPH, the vehicle independently went into LIMP Mode and failed to accelerate while depressing the accelerator pedal. The contact stated that several unknown warning lights flashed on the instrument panel. The contact was able to coast the vehicle over to the shoulder of the roadway. The contact drove the vehicle to an independent mechanic, and it was discovered that there was no oil in the engine. A diagnostic test was performed; however, no oil leaks or failures were discovered. The manufacturer was then notified of the failure and the contact was advised to take the vehicle to a dealer for service. The mechanic added oil to the engine and the contact drove to the local dealer. The contact was informed that an oil change was needed; however, the cause of the failure was not yet determined. The contact was also informed that the vehicle was not covered under recall or warranty. The vehicle was not repaired. The failure mileage was approximately 177,000.
The engine started smoking and knocking really bad. Took it to the kia dealership and was told a piston o ring and gasket went bad because of heavy oil consumption that caused antifreeze to leak inside the motor while sitting still and this was causing the burning smell because the cylinder had gone bad because of this. The dealership states this was a known issue with all kias from this year and should be under recall. So I called kia because the car only has 80k miles and they informed me it's not apart of the open recall because it's a cadenza. What if I hadn't went back outside and seen the smoke and the car caught fire and burned my home down. It seems like kia knows all of these motors are bad and trying to keep it secret
A few weeks ago we were driving into town and the car had a light turned on and the smoke was coming out of the front and it smelled burnt. Then the car completely stopped. We almost wrecked. I was pregnant at the time and shod know what could have happened if we wrecked because the car had completely stopped and turned off. I Had to tow the car to a mechanic. The mechanic has not looked at it. It’s just there parked. 1367 US Hwy 41 N, Calhoun, GA Proctor garage. I have been waiting on an update on recalls since the letter I received as I was reading it and it clearly said on the bottom a big warning notice if the car smoked and light turned on to take to local Kia dealership. I paid full price at a dealership for this car only had it for a full year and this happens. This is very dangerous my family and I could if really gotten hurt now I am without a car that has a recall and Kia is not willing to help at the moment. I am not the first person that has had problems with the Kia cadenza 2014. Something needs to be done for us who own it. It’s a waste of money with Kia worst thing money don’t grow on trees and I need Kia to show up for this situation I need my car fixed or a settlement for owning a recalled Kia Cadenza.
The contact owns a 2014 Kia Cadenza. The contact stated that the vehicle made abnormal sounds while starting. A burning odor was also detected while starting and driving the vehicle. The ABS, traction control, and several unknown warning lights were illuminated. The contact's left foot and left arm were burned by smoke and an unknown fluid coming from the air vents. Medical attention was not received. The dealer was made aware of the failure; however, the vehicle was not diagnosed or repaired. The contact stated that the engine had previously been replaced twice due to faulty cylinder head bolts, but the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 136,000.
The vehicle has been carefully maintained and received the 144,000-mileage thorough maintenance service which was performed at the KIA dealership in August 2023 three months prior to the incident. While driving in November 2023 the Malfunction Indicator Light came on. I took the vehicle to the same dealership. After 3 days in the service department, I was told the engine is burning oil. They found code P0021, but further diagnosis is required. The "Service Department" told me the vehicle requires an engine replacement. I purchased the 2014 KIA used in 2015. The warranty is for ten years (2024) yet evidently, according to the Service Department and KIA, because the car was on the sales lot in 2013, the warranty is expired. It is not a safe car and the recall, as noted on this site, indicates the same. I cannot count how many recalls this vehicle has had including the windshield possibly being loose and the power steering malfunctioning. I've had the headlights replaced three times and the air conditioning completely fixed after it went out. ( that's not a safety issue, but another indicator of the poor quality of this vehicle.) It appears KIA is aware of the severe engine issues in this 2014 KIA Cadenza and other KIA models, and I believe the Company understands the dangers involved in driving, and even parking this vehicle. I am beyond upset as this vehicle is currently not functioning. (and it's parked far away from a building.) Please advise. Thank you for your time.
There is a clatter at startup of the engine. I researched the issue and KIA has a service bulletin about the issue and a resolution for the problem. I had the vehicle brought to the dealership for the windshield recall and asked them to please apply the service bulletin since the timing chain has the discussed rattle at startup. They will not fix the issue. even knowing that it is causing internal engine damage for a defective part. If these vehicles are not fixed properly, the engines will expire prematurely and may cause serious injury.
There is carbon building up on the intake. Which causes the engine to lose power. Even at 70 mph engine will cut out causing the car to decelerate in traffic.
The engine failed. There was no warning lamp or message of the problem prior to the engine blowing up. I now can’t use my car.
I was driving my car at about 70 miles per hour then all of a sudden it went from 70 to like 40 and wouldn't pick up speed the engine light did come on I did get it to a mechanic to have my coils and spark plugs change but car was still knocking mechanic said it was the engine even before this it was always a knocking noise at start up even after oil changes everytime I call about this engine issue it's always cadenza not included but I see that most of the complaints is about the engine the same issues like the others my car is paid for but can't drive it if this problem was known we should be included for a new engine people like myself only work 32hrs cause my job like others are not doing good don't have the 5 to $10,000 kia dealership quoted me at to fix this car that was already known to be bad this is sad but im going to keep pushing until I get to the bottom including a lawsuit because this is not fair at all.

ON COLD START THERE IS A CLICKING NOISE WHICH IS COMING FROM THE TIMING CHAIN TENSIONER. WHEN I LOOK IT UP IT TELLS ME THE YEARS THAT WERE AFFECTED WERE 2014-2016. EVEN THOUGH IT WAS SUCH A COMMON ISSUE WHY WAS THERE NO RECALL ON IT TO BE REPLACED?
I WAS TRAVELING ON CITY STREET AT 35 MILES PER HOUR WHEN ENGINE HAS STALLED SUDDENLY, WITHOUT ANY WARNING. I LOST POWER STEERING AND BARELY MADE IT TO THE SIDE OF THE ROAD MOVING BY INERTIA. I WAS VERY LUCKY THERE WAS NO CAR BEHIND ME AND I WAS ABLE TO STOP SAFELY. IF THERE WOULD BE OTHER TRAFFIC SITUATION, SUCH PROBLEM WITH THE CAR COULD POSSIBLY RESULT IN FATAL ACCIDENT. THE CAR WAS TOWED TO GROSSINGER KIA DEALER IN LINCOLNWOOD, IL
Engine, electrical, and powertrain is faulty on this 2014 KIA Cadenza and many other models of this same vehicle. After researching for alternate engines or engine replacement, there are many Cadenzas experiencing the same issues and are often parked due to these issues with no maintenance or replacement options as a result of the cost being way too high. When KIA was contacted, they replied that they do not have engine replacements and that servicing of the vehicle expires after the car is paid off.
WHEN ACCELERATING FROM A STOP, IF DONE IN A START, STOP, RESTART FASHION, IT DOES NOT IMMEDIATELY RE-ACCELERATE. THIS CONDITION CAN OCCUR WHEN STOPPING PRIOR TO PULLING OUT INTO TRAFFIC. *TR
