2022 KIA CARNIVAL Fuelpropulsion System Problems

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.

Fuel door will not open, there is no manual override, vehicle cannot be refueled and since there is no emergency release it caused me to be stranded at a gas station at night with my 4 kids which is a huge safety concern and should be taken seriously as this is a safety and drivability issue that I should not be held responsible to pay for when it is at no fault to me it is a design/system failure.

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...

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.

Fuel gauge does not provide accurate representation of fuel amount. The car will read empty with 100 miles .

Around 17,000 -18,000 miles, the engine started to shutter like it wanted to die or wasn't getting enough fuel. While driving, it feels like it's trying to accelerate by itself even when cruise control is set. Even when it is just in nurtural it does it.. Still waiting to get the car into dealership to figure out the cause.

Beginning of January, when I went to drive home from work my check engine light was on and my Kia Carnival wouldn't accelerate over 10 mph. I let it run longer and tried to drive again and it wouldn't go over 20 mph. Let it sit a while longer and it finally drove normally but the check engine light stayed on. I called and made an appt with Kia in Fort Wayne immediately after it happened but they couldn't get me in for almost 2 weeks. The day I took it in (Jan. 22) the vehicle/engine shook anytime I accelerated. It did this the entire drive from my home to the Kia dealership. They ran diagnostics and found there was a sensor error with the injectors. They test drove it and said everything was fine. I got it back on Jan. 25 or 26th and it was fine. Then on...

On three separate occasions when the temperature was below -20C, this brand-new vehicle stopped working due to ice in the throttle body. Vehicle had to be towed each time. The dealer service manager informed me that the new design no longer heats the throttle body, and condensation jams the mechanism. In my mind this is a safety risk because (1) the car stops working while driving in traffic and (2) it's a family vehicle, putting up to 8 passengers at severe risk of cold-related injuries when stranded. The dealer has confirmed that this has occurred for at least three other customers at this one dealership. Each time they have inspected and disassembled the assembly, cleared the ice buildup, and applied a silicone lubricant. On the first and third occasion only, the "Check Engine" light came on. On the second occasion, the car simply died while driving, and I had to...

Vehicle mileage was about 1,750. Check engine light came on immediately after starting the engine and vehicle had a slight vibration. Drove to dealer and vehicle started shaking badly while accelerating and had slight burning smell inside the cab. Was told #6 cylinder was miss firing and fuel injector needed to be replaced. Dealer has fixed the issue and seems to be ok as of now.
