What 20 owners told NHTSA about the 2026 Kia Carnival Hev

This new 2026 Vehicle faced multiple issues within a few weeks of purchase as stated below. 1. The instrument display panel or the main display screen of the car stopped working. The screen was completely blank and would not turn on. (confirmed and reproduced by Kia dealer, service order attached) 2. An electric short caused the radio to fail (confirmed and reproduced by Kia dealer, service order attached) 3. The car battery died, rendering the car completely unresponsive. The car had to be towed to the Kia Dealer. (confirmed and reproduced by Kia dealer, service order attached) All of the above 3 issues happened one after the other. The first issue essentially disabled safety features of the vehicle as the display panel that displays rear view camera, camera monitoring system (CMS), etc was not able to display any information. An eventual electric short and a dead battery rendered the vehicle inoperable. The official Kia dealer attempted to diagnose and repair the vehicle. The vehicle was at the dealer service for 15 days. The dealer initially suggested that a part needs to be replaced and is in backorder till May 2026. However subsequently the dealer then claimed that the vehicle is now operating normally and should be taken by the customer. No root cause of the electric short and battery and screen failure was disclosed. Also contrary to what is stated in the service order, the service manager at the dealer verbally suggested that they did not replace the malfunctioning component.

I am submitting a safety complaint regarding unexpected and inappropriate automatic braking behavior at low speeds involving the parking sensors, rear cross-traffic alert, and/or automatic emergency braking system. While performing normal, low-speed maneuvers such as backing out of street parking spaces or parking in tight urban environments, the vehicle abruptly applies the brakes even when no imminent collision exists and when obstacles or traffic are clearly visible to the driver. In one frequent scenario, while exiting a parallel out of a parking spot into traffic, the vehicle suddenly stops itself while partially in the roadway due to a car approaching in the rear. This occurs despite sufficient clearance and approaching vehicles slowing to yield or even happens AFTER the approaching vehicle has passed already! This creates a dangerous situation where my vehicle is immobilized in active traffic, increasing the risk of rear-end or side collisions. The driver behind me sees me stopped in middle thinks that I'm waiting for him, when really my intention was to come out of the spot and then finally it releases the emergency brake and then my vehicle juts out into the roadway. Also, during parking maneuvers, the vehicle applies emergency braking despite having enough space, SLOW speed, & the driver having full visual awareness via the backup camera. This removes the driver’s ability to make precise low-speed adjustments. The override behavior is also unsafe. Regaining control requires a firm brake press, after which releasing the pedal causes the vehicle to move abruptly, eliminating precise control and increasing collision risk. This behavior is unpredictable, inappropriate for dense urban driving, & creates hazardous situations rather than preventing them. I believe this constitutes a safety defect in the vehicle’s braking and driver-assist systems. Concerned this could lead to serious accidents, particularly in urban environments. Friends have same problems!
