Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The main complaint across these eleven cases is a parts shortage tied to NHTSA recall 23V652000 (Service Brakes, Hydraulic). Eight complaints mention receiving the recall notice but finding no parts available at dealerships, with owners frustrated that Kia exceeded what they felt was a reasonable repair timeline.
Three complaints describe more serious events: an engine fire at 30 MPH with check engine light on, persistent burning oil odor after a valve cover gasket replacement, and a complete engine stall at 35 MPH with no warning lights. All three owners tied these failures to the brake hydraulic recall, though mechanics only diagnosed a valve cover gasket issue in one case—the others remain undiagnosed because the vehicles weren't repaired.
The stall and fire cases involved mileage near 160,000 and 94,000–153,000 miles respectively. Check engine lights appeared in the burning-oil and fire scenarios. Several owners report Kia acknowledged the parts issue but offered only rental vehicle reimbursement in one case. The recall itself has not been completed on any of these vehicles due to parts unavailability.
