5/5 Overall
NHTSA 5-Star Safety Rating
The complaint picture for the 2021 Kia Stinger is relatively thin at 16 total reports, so patterns are limited. Engine behavior draws the most attention, with owners describing stalling or loss of power, most often tied to the auto stop-start system cutting out unexpectedly at a stop, requiring a full shutdown and restart to recover. A separate engine complaint describes sudden loss of drive power mid-turn with no warning lights, the vehicle recovering after a restart. Brake-related reports, while fewer, describe a noticeable skip or inconsistency during braking, and at least one owner reports heavily worn rotors and warped rotors on a relatively low-mileage vehicle, with the braking system suspected of holding partial pressure and generating excess heat.

Crash-Related
By System
The 2021 Kia Stinger has 6 recalls, the most serious involving fire risks: an oil leak from the left turbocharger feed pipe on 3.3-liter turbo models can ignite near hot engine components, and a separate issue near the anti-lock brake control unit can also cause an engine compartment fire.
On the fuel delivery side, a sticking valve inside the high-pressure fuel pump can over-pressurize and cut drive power without warning, and a plastic burr left in the fuel pump's jet nozzle can block fuel flow and cause the same result. Both issues raise the risk of a crash from sudden power loss. There is also a software issue in the instrument cluster that causes the fuel gauge to read higher than the actual tank level, which can lead to an unexpected stall if the driver trusts the gauge and lets the tank run dry.
