Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The alert “consider taking a break” with the coffee cup symbol won’t stop going off. It goes off when I first start driving, it goes off every other minute sometimes, it does off for no reason all the time. It is so distracting. Today it was rainy and I’m sure is one reason it kept going off. It was also garbage day and someone put their garbage can on the road right on the line. The alert had gone off 15 times within my 20 minute drive after school drop off. It was making me angry and was super distracting. I was looking at the screen instead of the road as it started beeping again and didn’t see the garbage can. It smacked my side view mirror into the passenger window and shattered it completely. A minor thing, but is going to cost a ton. It’s frustrating to feel trapped into constantly being annoyed whenever I need to drive because there is no way to shut it off, but it literally goes off for no reason. It goes off so much I don’t take it seriously at all. It’s literally useless. And it’s not a little warning. The beeping is loud, the image covers a big portion of the screen, and it turns off my music and my gps prompts. It aggressively demands attention. It can’t keep doing this. I can’t be this distracted with my kids in the car. Every seat is full and I have to drive 30 minutes to one school and 10 minutes to the next school for drop off and pick up every single weekday twice a day. I need them to be safe, but that’s less possible when this alert is constantly going off and demanding attention the way it does. It’s a serious risk. It is reckless to put something so distracting in a vehicle that can cause death from an accident. I could understand if it went off after 4 hours of driving, but that’s not what’s happening. Multiple people have complained about it in social media. Something needs to be done to get this off of or vehicles. It’s unnecessary to suggest someone take a break. Especially after 5 min. That’s not a sensor warning about an actual problem.

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.

Battery shuts down overnight. To get the car to start you need to pop the hood the night before use a jump start and keep your manual key handy. All electronics shut down completely

I purchased a new 2026 Kia Carnival EX and noticed an unusually intense amount of heat coming from underneath the vehicle on the passenger side, particularly around the rear passenger door/second-row seating area. I first noticed the issue while the vehicle was parked and I was standing outside the open rear passenger door installing car seats and floor mats. The heat radiating from underneath the vehicle was intense enough that my feet and lower legs became extremely hot while standing next to the vehicle I also noticed that the seat/floor rails and other exposed metal components in and around the second-row passenger area became extremely hot to the touch. I could only keep my hand on some of these metal components briefly before the heat became too uncomfortable and I had to remove my hand. I am concerned about the safety of this condition because these hot surfaces are in an area routinely accessed by passengers, including children entering and exiting the second row. I am concerned about the potential for contact burns as well as whether the amount of heat being transferred into the floor, rails, and surrounding components could indicate an exhaust, emissions, heat-shielding, or other mechanical problem. The vehicle is available for inspection upon request. At this time, the exact component or system responsible for the excessive heat has not been identified. The issue has not yet been reproduced or confirmed by a Kia dealer or independent service center. I have contacted Kia service personnel regarding having the vehicle inspected. I was informed that if the vehicle is inspected and the dealership cannot reproduce or identify a problem, I may be responsible for an approximately $210 diagnostic charge. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another independent party regarding this issue. There were no warning lights or dashboard messages indicating a problem before or when I noticed the heat

When accelerating, the car feels stuck to gear up. After 2 seconds of loud revving, it would switch and have a prominent jerk motion that it finally switched gears. There have been times the car wouldn't go past 30 mph, stuck at the gear making a loud noise. This is dangerous! There's absolutely no way I can get on the freeway never getting past 30ish mph. I checked recalls for this vehicle and there isn't any. No warning lights in the dash.

Grill on bumper allows large objects to fly through hitting condenser. This is an issue, it happened to my vehicle and the identical loaner car we were given while our car was in the shop for repairs. I was told by the dealership to solve this problem carnival owners should follow other cars at a greater distance. Because I have children I already set my cruise control to follow other vehicles at a 4 car distance…. How much further should a carnival owner allow?

2026 Kia Carnival MPV Hybrid SX Prestige(Exterior: Astra Blue Interior: Tuscan Umber / Off-Black) purchased December 2025. Two separate safety-related defects have gone unresolved for 31+ cumulative days across two dealer repair visits. DEFECT 1 — INSTRUMENT CLUSTER: Instrument cluster screen goes blank while driving, eliminating speedometer, TPMS, and all warning indicators. First observed February 2026. Dealer visit February 13–17 (4 days): technician said could not replicate. Defect recurred. Kia has since issued a federal safety recall confirming this exact defect — citing FMVSS noncompliance and stating the blank screen increases crash risk due to a software error causing overheat protection mode. Vehicle was at dealer for an active safety recall defect that went undiagnosed during a repair visit. DEFECT 2 — SEAT MODULE: Second-row seat module failed. Vehicle returned to dealer March 5 (still there, 27+ days). Wiring harness replacement attempted approximately March 21 — failed, defect persisted. Kia Engineering formally escalated approximately March 24. Seat module ordered but not yet installed. No resolution or completion date provided. Vehicle has been out of service 31+ cumulative days. Safety recall defect went undetected during prior dealer repair visit. Both defects remain unresolved on a vehicle purchased just 97 days ago.
