2026 Kia Carnival

The car now auto locks on the vehicle upon exit, even with key fobs in the car. The first few months I had the car this did not happen. I left me keys and phone in the car. I turned vehicle off, exited the vehicle and walked around to get my daughter out of her car seat. After about 5-8 seconds of walking around. The car automatically locked. The key fob was placed in the center console. My 1 year old daughter was left trapped in the vehicle, placing her life in danger. I had to call emergency services and have them open it for me. This is a huge saftey concern. I never changed any setting to allow for this. The car should not auto lock, and definitely should not lock with keys in the vehicle a few seconds after exiting.

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.

Sliding Door Sensor Failed My daughter was getting in the van, when her brother hit the door button, if my husband wouldn’t have glanced over at that exact moment and pulled her back, this would’ve been another story. THE SENSOR IS NOT SENSITIVE ENOUGH! We as mothers are demanding sensors sensitive enough to detect smaller, fragile children!

Air conditioning has never worked. It was purchased in the winter. As weather warmed, we noticed the air conditioning was never cold. Dropped it off at the dealership. Their first comment before looking at the vehicle was that a rock probably hit it and broke the air conditioning. After inspection they said it was a rock so it isn’t a warranty item. Seems suspicious. Possibly warranty fraud to try to get money from a consumer for a covered defect. If that’s the first thing they suggested was wrong, how often is this happening and is it fraud or a design defect.

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.

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.

My car has just under 3,000 miles. While driving home from a friend's house this morning my car would not go above 31 mph. I could put my pedal all the way down and nothing beyond 31 mph. I am reading a lot of people with this same exact issue with their hybrid Kia Carnival. Most note it happens in cold weather. So it is worth noting that it is 21 degrees here today. Regardless this is a serious concern especially as some report is happening on highways

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!

The car will not accelerate past 31 mph no matter the gas petal position, during cold mornings. Downhill or uphill, in any “drive mode” it will not go past 31 with the petal all the way down. Acceleration onto a highway is impossible. Stopping and restarting the entire vehicle seems to reset this and allow for speed over 31mph. This has happened 5-6 separate times when the temperature is below 35F.

System failure the warning lights on dash went crazy all of them flashing Speedometer wouldn’t work, lights won’t work, camera system won’t work, abs won’t work, tailgate won’t open, side doors won’t open, heat/ac controls stop working , windshield wipers stop working. They had 20 error codes the first time this happened Yes vehicle has been in shop 2 different times This happened the first time on November 24 shop had my car until November 28. Drove car for 9 days took car back in on dec 8 shop has had it still do not have as of 12-18-25 They have said the first time they had no idea what was wrong with it but got it to stop doing it. On dec 8 it started doing the same thing. I brought it back and they at first couldn’t get it to stop. From my understanding it has stopped and tests are coming back good but that is what I was told the first time. They are trying to get it to do it again by driving it before Kia motors will allow them to release it to me. I am getting no where with Kia motors, they are not calling me to let me know what they are going to do for me. I feel this vehicle is unsafe there is no garintee this won’t happen again while I am driving. All I want is out of this lease. 9 days and brought it back in for same issue. I was driving when all of this took place
