I was driving my 2014 Kia Cadenza and then I noticed the vehicle has lost power and all the electrical components shut off (Odometer , dash lights and radio ) , as I was cruising down the road waiting for vehicle to slow down I noticed vehicle steering was very heavy and didn't have any breaking power , I pull into a place away from road when i noticed that there was smoke coming from the car and the car was catching fire , in that moment I opened the hood and I did have a fire extinguisher . I was pushing the vehicle back while spraying it and was able to turn off the fire before spreading . The car will require a new engine . I reached out to multiple kia Dealerships but they will not accept repairs on the car and will redirect me to kia customer support . It's been a hassle for the past couple of months and I can't seem to get to a resolution

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. …
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. …
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! …

Engine light is on the dashboard and can not conduct the Emission Test. I was told it's a oil consumption problem. And that the same problem that the sorento and sportage is doing. That is currently have a lawsuit going on. I was told the engine may start knocking soon. I was also told at shop that can cause the sensors to get false reading and send error signals to the engine also. If the engine cut off while driving or stall it can put my life and others in danger and cause a major accident. It was confirm at shop and I was told it's a recall on the engine. The dealership tells me not for the credenza and it's doing the same things as the models that is being look at and had a lawsuit going on. My cadenza is wrll6keot and under miles and should not be having this problem. Kia should help me with this problem. Please help me with this mattet.
