criticalENGINE,FUEL/PROPULSION SYSTEM
Filed: Mar 2026

Your 2024 Sportage experienced sudden engine shutdowns and severe bucking while driving, occurring three times within a month despite repeated repairs. The first incident involved a blown ignition fuse and faulty fuel pump relay; the second showed the ignition fuse blown again with a shattered catalytic converter; and the third revealed engine piston failure causing loss of compression. Kia ultimately replaced the entire engine long block to resolve the issue.

NHTSA #: 11725255
criticalENGINE,FORWARD COLLISION AVOIDANCE
Filed: Oct 2025

Your adaptive cruise control has caused sudden hard braking when other vehicles move across lanes, dropping your speed from 60 mph to 35 mph in seconds—creating a rear-end collision risk. Additionally, your engine makes loud clicking sounds every time you start it for the day, and the noise has gotten worse over 1.5 years; the dealership has been unable to replicate either issue despite multiple visits and overnight service attempts. Fixes may involve recalibrating the forward collision avoidance system software and diagnosing the engine timing or internal components causing the startup noise.

I was stopped at a red light in middle lane with traffic all around when the car just stopped running. After a few tries it started again.
