SC368 CROSS OVER FUEL PIPE recall incomplete by kia of des moines

NHTSA ODI 11748281

Jun 12, 2026Fuel system

I am writing to formally complain about the delay in repairing my vehicle under an active recall involving the fuel system/crossover fuel pump. I have been informed that the required part is on backorder and that the repair may not be available until the end of July. My concern is that I am experiencing strong fuel fumes in and around the vehicle. The odor is severe enough that it is causing headaches, and I do not feel it is safe for me or my children to ride in the vehicle. Given that this recall involves a fuel-related component, I am extremely concerned about both the health effects of continued exposure to the fumes and the potential risk of fire. At this time, I do not believe the vehicle is safe to operate. I am requesting that Kia provide an immediate solution, including one or more of the following: A loaner vehicle until the recall repair can be completed; Rental vehicle reimbursement; Expedited repair assistance; or Any other reasonable accommodation that ensures my family's safety.

Fuel leak at pipe connection between the fuel pipe and fuel rail. Nuts securing the high-pressure crossover fuel pipe to the fuel rail loosened, leaking raw fuel, leading to risk of fire. This has been reported and confirmed by Ron Bouchard Kia, of Lancaster, MA, USA. It is a part of Kia Recall SC368 (NHTSA ID: 26V232). We noticed the vehicle was leaking a substance in April 2025. After receiving recall notice in April 2026, we brought the vehicle in to be check on XXX. We were informed on XXX by phone that our vehicle was affected and fell under this recall.

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.

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 $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.

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 the 29th I went to drive my vehicle and it had the acceleration problem again. I immediately called Kia and they couldn't get my vehicle in until Feb. 7th. I didn't drive it that day after the acceleration problem, but the check engine light was on again. I've driven it all last week because I need a vehicle. The check engine light will come on sometimes and sometimes be off. On Friday Feb. 4th the shaking happened again. It would shake when I accelerate. The check engine light was on all weekend. They looked at my car on Feb. 7th and the check engine light isn't on and it's driving fine for them at Kia. They ran the diagnostic and said it was the sensor error again. They said it was fine to drive because it wasn't happening right at that moment. I drove it home and it started to have the same issues again multiple times. I called the first time it happened again after service and they couldn't get it in until March 7th. It won't do it everyday, usually just cold mornings on the first start. It wasn't having the issue when I took it in for service. They looked at it and said it was fine. I get it back and it's doing it again. After 4 service visits I'm still having problems and Kia refuses to help or do a buyback.

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 roll to the highway shoulder. Note: On the "address" page, your form does not take a Canadian address, however this vehicle is also sold in America. My Correct postal code is J7V 8P4 and Province is Quebec.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2022 Kia Carnival Hev verdict →
