2022 Kia Carnival: check engine light

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.

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.

In October 23, 2025 I started to notice a fuel smell while I was driving the vehicle. The smell of fuel seemed more strong while I had the air conditioning running.I would shut off the AC and put the windows down. There was no leaks of fuel on the ground or close to the motor. No check engine light or messages was displayed on dash at anytime. My concern was that I’m constantly driving my small children in car seats to and from school, sports, and appointments the smell the fumes will cause headaches or worse car will catch fire were we would need to make a fast exit out the vehicle. So I made an appointment with Kia of Stockton and they scheduled me for 10/29/26 at 9:30am. Kia first diagnosis was undetermined and charged me another $315 just to keep diagnosing on top of there first fee of $315. Kia discovered after removing the foam that protects the fuel rail the leak was coming from fuel injectors and fuel rail. Fuel injector leaking where injector inserts into rail. Repair was needed due to failure of fuel rail housing not sealing properly. Kia also replaced associated components with the fuel rail clips, bolts, flanges, high pressure sensor, foam, and injector wire harness. According to Kia there tech found short in the injector harness.

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.

We have been having an acceleration issue for over a year now. The vehicle will be running fine and the randomly not go over 30 MPH. You could have your foot the floor and the vehicle will not shift or go above 3 rpm’s. This has caused us to be in many dangerous scenarios getting onto an interstate. This has almost caused us to be rear ended multiple times. Problem has be reproduced at the dealer and “repaired” though the problem continues to happen. Sometimes the engine warning light is on when it happens, others times it is not and happens with zero warning.
