2022 Kia Carnival engine problems

Filed Apr 6, 2026 · Engine, Fuel system · IA

Engine light turns on every couple months. The Kia either stops accelerating and goes into “limp mode” or gives code for misfiring cylinders. Took to dealership several times, they did nothing but reset battery so light goes off. Unsafe when driving my family around and has turned into an unreliable vehicle. SO frustrating for a new vehicle to have these issues.

My engine smells like fire and fuel my can will not start or do anything. There was smoke coming out of it. The van has had several issues since buying it. Now it’s completely disabled I heard a popping noise as I was driving and then it died and has not started since.

I am unsure as for what is wrong with my car the dealership keeps saying its running rich and there is a recall on several 2022 Kia Carnivals that say it could be a faulty fuel rail tube. They have also said my map sensor is failing. My check engine light appeared a few days ago and has since been cleared and hasn't came back on, however it is just a matter of time. My children ride in this car as it is my daily driver and I have extremely head headaches. The dealership inspected the car and stated it did not smell like fuel however it definitely does.

Dealer says recall sc211 doesn’t apply to this vehicle, however CEL is displaying (once again) with DTC “P0191 Fuel Rail Pressure Sensor Range/Performance”. Kia dealer has does minimal investigation/diagnosis with no resolution.

While driving my 2022 Kia Carnival Prestige, the engine started knocking and the vehicle started sounding like it was going to turn off. There was no alert or light on until we got to the service center where the check engine light came on. I took to the nearest dealer with service center for Kia for inspection and repair which the dealer's service center indicated it was an engine failure at 62,203 miles. This failure was hundreds of miles away from my home. I had to return to my state on a rental vehicle. The vehicle remained at the service center for 2 months for engine replacement. Prior to this event, I had serviced the vehicle at my home dealer's service center since I bought it. I performed all maintenance and my home dealer never alerted to an engine trouble before this event. Once I retrieved my vehicle, the vehicle was fine for few weeks and at 66,427 miles the vehicle started having issues with a check engine light on again. I took to my home dealer's service center and after inspection they indicated it was a bad fuel injector. The vehicle became unreliable and unsafe for my regular commute. Once I received the vehicle with the new engine the performance and sound was very different than my old engine had been since I bought the car. I believe the original engine has been faulty since I bought the vehicle.

I bought this car June of 2022. The car was days old and the front end started making a popping sound when you turn the wheels. The dealership changed front right axle. There is still a popping noise but now it’s from the front and the back. The transmission went out in February of 2023. They replaced the transmission. Since then the car shakes violently when accelerating, loses power when accelerating, the self drive mode turns on by itself. I have contacted 2 different dealerships about these issues. They say “ they cannot duplicate the problem.” This car is not a safe vehicle for me or my family to ride in. They won’t do ANYTHING about it!

In December of 2021 my 6 month old Kia Carnival lost power while on the Ohio turnpike when the engine shut down. At that time the dealership was unable to identify the cause. Since then the vehicle has been into the shop multiple times, has an issue with Cylinder 6 and is burning coolant internally which is likely the original reason for the unexpected engine failure. Kia has been ordered through arbitration to repurchase the vehicle, however are unwilling to even offer enough to cover the loan and take back their defective vehicle. I have seen reports online of other Carnivals having similar issues. There are no recalls for this, and Kia seems to have no intention of making sure this is addressed.

1. When accelerating (while driving on ECO Mode) the vehicle starts to shudder at times. When using Normal Mode, the vehicle will shudder while the brake pedal is being used at a red light. Front windshield cracks easily and paint easily chips with no sign of rocks hitting the vehicle. Called Kia Service to get the car looked at and they said they haven’t heard of such issues. 2. Doors are supposed to retract when closing if motion is occurring. A family member almost got her leg pinned by the door and our child almost got hurt on the shoulder because the door kept moving in closing mode when she was trying to get inside the car. Whatever sensor it has, it doesn’t work. 3. Roof Mold on driver’s side came off the roof while driving the speed limit on the highway never to be seen again. The passenger side almost went flying too. 4. iPhone XR does not work properly when synced to the car. It connects and disconnects out of nowhere. It becomes dangerous when using GPS. Vehicle system kept saying it needed a new software to be downloaded. Went to the site and downloaded multiple rimes, called the Customer Service about 3-4 times and last person I spoken to told me to ho straight to the Service Dept at the Kia dealership to get the software downloaded. No one at Kia knew how to download the software. After multiple attempts and Kia not “finding anything”, decided to spend extra money and get a new phone to resolve this issue. I have to have a software downloaded to the vehicle.
