2021-2026 Kia and Genesis Recall: Fuel Leak at Pipe Connection

A crossover pipe carries pressurized gasoline between the two fuel rails on the V6 engines in these Kia and Genesis models. The fasteners holding that pipe were, on some vehicles, never torqued to specification at the factory. A loose high-pressure fuel joint can weep gasoline in a hot engine bay, and gasoline plus heat is how an engine fire starts.

Kia and Genesis, both part of Hyundai Motor Group, filed matching recalls on the same day for the same defect. Together they cover 235,792 vehicles: 141,032 Kia Carnival minivans under NHTSA campaign 26V232, and 94,760 Genesis luxury models under campaign 26V229. No fires or injuries have been reported. The recall is preventive, prompted by a production problem the automaker found before it caused harm in the field.

The Issue

The affected vehicles use a V6 in which the two banks of cylinders each have their own fuel rail. A crossover pipe links the rails so both draw from the same high-pressure supply. That pipe bolts to the rails at threaded connections, and the retention fasteners have to be tightened to a specific torque to keep the joint sealed under direct-injection pressure.

Kia describes the root cause as a suspected production deviation, where the nuts were not torqued to the proper specification. A fastener that starts loose, or works loose over time, lets fuel seep out at the connection between the pipe and the rail. Because the leak is at a pressurized joint inches from hot engine components, the consequence NHTSA lists is direct: a fuel leak increases the risk of a fire.

The remedy is mechanical and straightforward. A dealer inspects the crossover pipe connection, tightens the fasteners to specification if the joint is intact, and replaces the pipe if it finds a leak. The work is free.

Affected Models

Vehicle	Model Years	Units
Kia Carnival	2022-2026	141,032
Genesis GV80	2021-2025	57,229
Genesis GV70	2022-2026	26,105
Genesis G80	2021-2025	7,195
Genesis G90	2023-2025	4,231
Total	2021-2026	235,792

The count skews heavily toward two vehicles. The Kia Carnival alone accounts for about 60 percent of the total, and the Genesis GV80 SUV makes up most of the rest. Four-cylinder versions of the Genesis models are not affected, because a single-rail four does not use the crossover pipe at the center of this defect.

Chronology and Investigation

Both automakers filed their Part 573 defect reports with NHTSA on April 10, 2026. Kia assigned the recall number SC368; Genesis assigned 033G. The shared timing, shared defect, and shared corporate parent point to a common assembly or supplier process rather than two unrelated problems.

Genesis VINs became searchable at NHTSA.gov on April 11, 2026, and Kia VINs followed on April 24. The two brands then split on notification, which reflects how far along each remedy was when the campaigns opened.

Reported Incidents

NHTSA lists no fires, crashes, or injuries tied to either campaign. The automaker identified the torque problem as a production deviation and moved to recall the vehicles before a field failure occurred. That makes this a preventive action, which is the better version of a fuel-leak recall to be reading about.

What Owners Should Do

Kia mailed owner notification letters on June 2, 2026. Owners can run a VIN at NHTSA.gov or call Kia customer service at 1-800-333-4542 and reference recall SC368.

Genesis moved in two steps. Interim letters explaining the safety risk went out June 3, 2026, and a second round follows once the final remedy is confirmed available. Genesis owners can call 844-340-9741 and reference recall 033G. For either brand, the inspection and any repair are free.

Symptoms to Watch For Before the Pipe Leaks

A loosening high-pressure fuel joint usually gives off warnings a driver can catch. Watch for four in particular:

A strong gasoline smell. The clearest sign. If you smell raw fuel around the front of the vehicle, especially after starting or shortly after parking, treat it as a leak until proven otherwise.

Fuel drips or stains under the engine. Look for wet spots or the sheen of gasoline on the ground beneath the front of the vehicle after it has sat.

A rough start or uneven running. A joint that bleeds pressure can make the engine harder to start or leave it running unevenly until pressure builds.

A check-engine light with fuel or misfire codes. Lost fuel pressure and lean running can trip the light. Have the codes read rather than clearing the light and driving on.

If you smell gasoline, stop driving, shut the engine off away from buildings and other vehicles, and have the car inspected before you drive it again.

How Long Will the Recall Repair Take?

An inspection and a torque check on the crossover pipe fasteners is quick work, well under an hour, and it resolves most vehicles in the campaign where the joint is intact and simply needs to be tightened to specification.

Replacing a pipe that has actually leaked takes longer and depends on parts supply. Genesis has signaled the difference by mailing interim letters first, which means some Genesis owners will wait for the final remedy parts before the repair is fully available. Kia's remedy was ready at notification.

Bottom Line

A high-pressure fuel leak in a hot engine bay is one of the more serious defects an automaker can name, and the honest read here is reassuring on one point and cautionary on another. Reassuring, because no fires or injuries have happened and the fix for most vehicles is a torque wrench. Cautionary, because the failure mode is fire and the trigger is a fuel smell that is easy to dismiss.

Run your VIN, schedule the free inspection, and do not ignore a gasoline odor while you wait for the appointment. If you catch the smell, park away from structures and stop driving until a dealer has looked at the pipe.

Two same-day NHTSA campaigns for one defect across Hyundai Motor Group: Kia Carnival (26V232, 141,032 units) and Genesis GV70/GV80/G80/G90 (26V229, 94,760 units), 235,792 total. Root cause is a suspected production deviation where crossover fuel pipe fasteners were not torqued to specification.

Hyundai Motor Group has run multiple fuel- and engine-related fire recalls over the past decade across Hyundai, Kia, and Genesis. This campaign is narrower, tied to an assembly torque deviation on the V6 crossover fuel pipe rather than an engine-internal failure.
