Is there a fix? Manufacturer service bulletins

The failure pattern owners describe
Thirteen of fourteen complaints center on recall NHTSA 23V652000 (Service Brakes, Hydraulic) with parts perpetually unavailable despite owner notification and dealer contact. Owners consistently report that both dealers and the manufacturer confirmed no parts were in stock, with manufacturers sometimes exceeding what owners considered a reasonable repair timeline. One owner noted Kia's interim guidance to park the vehicle outside rather than in a garage—hardly a workable long-term solution.
One narrative stands out: a driver experienced complete brake pedal failure during stop-and-go driving in warm weather. The brake pedal went soft, went to the floor, and the vehicle would not stop, resulting in a collision with another vehicle that the owner believes totaled the car. Fluid was pooled underneath. The vehicle had a check engine light on but was never diagnosed. This complaint indicates the hydraulic brake system experienced a catastrophic loss of fluid or pressure, consistent with what a manufacturing defect or latent defect in the brake system might produce.

From what I understand kia has no fix for manufacturer recall # SC284UB and NHTSA recall# 23V652. That is unacceptable and unprofessional. Kia is a hugh car dealer and they are saying there is no fix yet! I can't believe kia would put people and families at risk. Kia's action plan to put your car outside and not in your garage , is ridiculous. I was never contacted about this recall, that's…
