2024 Kia Niro

Electrical system complaints lead the 2024 Kia Niro's complaint picture, followed by a smaller cluster of visibility reports. On the electrical side, owners describe repeated 12-volt battery failures resulting in complete power loss, with some experiencing multiple dead-battery events within the first year of ownership. A separate electrical complaint involves the forward collision system activating unexpectedly with no apparent obstacle present, causing the vehicle to brake hard without warning. Visibility complaints center on the interior surface of the windshield frosting over in cold weather, starting at the edges and spreading toward the center of the driver's sightline, with owners reporting warm-up times of 20 to 30 minutes before the glass clears enough to drive. The remaining complaints, including an unintended acceleration report, appear in single filings and don't represent a pattern across multiple owners.
