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

On Dec 12th the speedometer repeatedly showed very incorrect values, both displaying much faster than the vehicle was traveling and displaying zero when the vehicle had accelerated. We have not been able to replicate the issue. And it went away after shutting down and restarting the vehicle. The vehicle has not yet been inspected by anyone. From a safety perspective the speedometer accuracy is in question. Prior to this incident the screens had all shut themselves off. After the incidents the main screen (with the speedometer) rebooted itself a few times while driving. We have video of the speedometer acting incorrectly but unable to upload the correct format. See included screenshot while driving about 30mph with the speedometer showing zero.

Vehicle parked for 48 hours (Sunday 23 Nov evening) under carport, no keys near it. When approached on 26 Nov 10am , it was found with dead battery. Nothing was on when it was parked.

After purchasing vehicle (4Sep25) the following week's notice wet spots in drive way first assumed to be from A/C but not the it is November and A/C is off the wet spots are still showing up. Checked under the vehicle and noticed oil all around the PCV tube. Took vehicle to Allentown Kia. They confirmed there is a oil leak but the leak is from the oil pan gasket. The vehicle has 400 ish miles on it and was i believe a quart low on oil by the time I took it in for repairs.

URGENT SAFETY CONCERN/ISSUE On [XXX], while driving my 2026 Kia Carnival Hybrid SX Prestige, it lost all power without warning, leaving me unable to accelerate or control the vehicle. This created an unsafe situation as I was traveling at 40 mph when all power was lost. What happened to me was a serious safety hazard. The vehicle was brand new with only 1351 miles at the time. Several warning lights came on including the hybrid system warning light. The vehicle was not drivable; there was no power at all. I had to tow the vehicle to a Kia dealer where it took 17 days to repair with a new power module. On [XXX], (after the vehicle was repaired), I was driving the vehicle when the POWER alert flashed on the dashboard. I did not lose total power yet, but the literature advises that I take the vehicle into the dealership asap to have them look into the Power warning light coming on. I have an appointment on September 18, 2025. I have reported my issue to Kia customer service, and the dealership is aware of what is going on. I believe what is happening, (the abrupt loss of total power while driving) may be a widespread defect affecting the Carnival hybrid system in 2025 and 2026 model years. This is a serious safety issue that need corrected before someone is killed or seriously injured. Total loss of power at 40 mph or more cannot be permitted to happen. There should be some sort of safety bypass whereby the gas engine totally engages to the exclusion of the hybrid system, so total power is NOT lost at High speeds.

Driver assistance system. This system monitors vehicle variables and unnecessarily SOUNDS A WARNING to take a COFFEE BREAK!! Here is the issue. When driving I need critical warning information. It is distracting while driving to be alerted to a COFFEE BREAK warning. PLEASE direct KIA to enable drivers to TURN OFF this feature. Every 10 minutes I am getting a warning and the warning is completely unrelated to driver status or restfullness. Driver assistance systems should be able to have HUMAN control. This is an assistance system, not a safety system. Please direct KIA issue as system update to allow human control of driver assistance.

I purchased this 2024 Kia Carnival on 2/7/2026 with less than 10K miles. The vehicle has died while I was driving 4 different times. Twice each day that it happened. The first time was on 4/7/26. My car died on the way home from getting my kids from school after fixing a flat tire. The check engine light came on after getting a jump and when I took it to Auto Zone the battery was fully charged and the codes were for the Power Train, which didn't make sense for a brand new car. Miracle Mart told me that Kia needed to be utilized for any issues because I purchased the vehicle as is. Their solution was to tighten the "loose cables". On 4/25/26 the car died again two more times. Something is terribly wrong with this car.

Our 2024 Carnival has had a recurring engine oil leak that has required the vehicle to be left at the dealership 4 times for the same issue. Each time we get the van back the repair lasts about 1-3 weeks (depending on how often it's driven). Oil continues to leak from the engine area, creating risk of engine damage or a potential fire hazard if oil contacts hot components. The issue has not been resolved despite repeated repair attempts under warranty. The Carnival has 38,092 miles on it, and has been in the repair shop over 4 times. The 1st time it was put in the shop the van has 34,420 miles on it. Each time it has been left at the dealership for 9 - 17 days while the repairs were made. We have brought it to the same dealership each time and they have been very sympathetic and helpful. Not only does this issue cause the risks mentioned above, but it has ruined the concrete in my garage as well as added oil to the roadway which could cause an accident. I have all the repair orders from the first 3 repairs that I will attach. However I do not have thee current one because the vehicle is currently being repaired for the 4th time and I haven't received the finalized repair order documents. I can update this claim once the repairs are completed. I will be contacting Kia tomorrow and wanted to have a claim number started.

The fuel pipe in my 2024 Kia Carnival has been identified by Kia as part of Safety Recall SC368 due to a fire risk. The component is available for inspection at the dealership where the vehicle is currently located. My safety and the safety of my family — including young children in car seats — was put at risk because the vehicle carries a known fire hazard related to the fuel pipe, yet no remedy is available until June 2026 at the earliest, according to Kia Customer Care. Kia confirmed the recall and the fire risk but has not provided adequate alternative transportation, leaving a family with young children without a safe vehicle for an extended period. The problem has been confirmed by Kia Customer Care, who verified that my vehicle is included in recall SC368. The dealership also confirmed the recall exists but stated the remedy is not yet available. However, when I contacted NHTSA by phone to file a complaint, the representative stated they could not find my vehicle in their recall database, directly contradicting Kia's confirmation. This discrepancy between Kia's internal records and NHTSA's database is concerning and may prevent other affected owners from being aware of the safety risk. The vehicle has been surrendered to the dealership via tow due to the fire risk. It has not yet been inspected or diagnosed by the dealership service department. I have requested written confirmation that the vehicle is safe to drive before accepting it back. I was notified via a CARFAX alert and the risk was identified/confirmed by the manufacturer.

I reported a fuel smell in the cabin of my vehicle in June 2024. It was dismissed because they could not recreate the smell. I reported it again and they said that is just how the vehicle purges fuel. I reported it again and drove it right to the dealer when it smelled and multiple mechanics at KIA confirmed they smelled it. Reported it again in September 2024, then tried to deal with it, and reported it again in June and July 2025. In July they confirmed I had raw fuel in my evaporator canister. I also had misfire notifications on my dashboard which were dismissed as they could not determine where the misfire was coming from. The misfire stopped after they replaced my fuel canister but the smell never fully went away. I received an email follow up in July 2025 and I reported the smell was not as strong, but still occurring intermittently. They closed the case. I reported and had 2 open cases with KIA, and noted that I was feeling lightheaded and nauseous, as well as 2 of my 3 kids at the time.

My Kia vehicle has an ongoing engine oil leak that has not been properly repaired under warranty. The vehicle was taken to an authorized Kia dealership for diagnosis and repair of the oil leak. I was informed by the dealership that Kia engineers indicated that in similar situations the typical resolution is engine replacement. However, in my case, the dealership was instructed to attempt sealing the oil pan instead of replacing the engine. I was advised that if this repair did not resolve the issue, I could bring the vehicle back for further service. Unfortunately, the oil warning light has now returned on the dashboard, indicating the issue persists and the repair attempt was not successful. An unresolved engine oil leak presents a serious safety concern because loss of engine oil can lead to engine damage, stalling, or failure while driving. This creates a risk of unsafe driving conditions, especially when transporting passengers. My family relies on this vehicle for daily transportation, and the continued presence of the warning light makes the vehicle unreliable and concerning from a safety standpoint. In addition, the dealership has not provided a suitable loaner or rental vehicle large enough to accommodate my family while the vehicle is undergoing repair. This has created significant hardship as we do not currently have reliable transportation. The manufacturer should correct this defect properly and ensure the vehicle is safe to operate rather than attempt temporary or experimental repairs that do not resolve the root cause. The persistence of the oil leak after warranty repair raises concerns about the reliability and safety of the engine. I am submitting this complaint to document a potential engine defect that may pose a safety risk if engine oil loss leads to engine failure while the vehicle is in operation.
