2022 KIA CARNIVAL Complaints

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.

The dealer is attempting to classify the torn rubber and pulled-out wiring as “non-recall wear and tear,” but the damage is a direct result of: a latch that sticks, a door that does not close smoothly, a malfunctioning power sliding mechanism, and the repeated force required to compensate for the defect. Under recall law, when an unresolved defect causes additional damage, the owner cannot be held financially responsible for the resulting deterioration. This is a mechanical consequence of a defect, not a cosmetic issue.

Vehicle: 2022 Kia Carnival Component: Liftgate — right-side support/strut (shoulder) failure Safety Issue: The right-hand side trunk strut/support has completely broken, causing the liftgate to drop unexpectedly. The trunk will not stay open and can fall abruptly during use. This creates a significant safety hazard for adults and children standing underneath, and while loading/unloading cargo. There was no prior warning or misuse. The failure is structural and sudden. Resulting Risk: Risk of head/neck injury, especially for children or anyone attempting to open or hold the liftgate. The sudden drop makes the rear of the vehicle unsafe to use. Request: Investigation into whether this is a defect affecting other 2022 Kia Carnival vehicles.

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.

Frame of drivers side seat broke in half. I weigh under. 200 pounds and am the primary driver of the car

I went to use my vehicle horn when another driver pulled out in front of me and the sound was way off...it sounded like a clown horn. I subsequently took to the Kia dealer where they diagnosed that one of the horns failed and it was replaced under an extended warranty with a deductible payment. The failure of the horn compromised my safety and the other driver's as the other driver may not have heard my warning that my vehicle was where it was. There was no warning that the horn failed until I went to use it.

Left sliding door window (Drivers side) exploded while driving down the highway. Nobody was around us on a sunday afternoon at [XXX]. [XXX] We were on a flat road so no tension. There is no reason for it to have shattered (my daughter was sleeping laid back in the seat) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The Kia Carnival was parked a slight decline and when the button to close the passenger sliding door the door closed rapidly like a guillotine. Thankfully no children or body part were in the path of the door because it would have severely damaged them. After it closed rapidly the door was unable to be opened. The dealership is still working on the Carnival and it has been over 3 weeks and they said they have never seen anything like this since it tore off a bolt in the body frame and caused damage to the body frame and they were unable to open it. Still don't have a timeline for repair. Also concerned it may happen to the other side and the safety issues around it.
