ENGINE
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.

ELECTRICAL SYSTEM, SEATS, UNKNOWN OR OTHER
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!

POWER TRAIN, ELECTRICAL SYSTEM, SERVICE BRAKES
The vehicle (2025 Kia Carnival Hybrid) has suffered from a systemic parasitic 12V battery drain since the first month of ownership. The first occurrence was July 20, 2025, requiring a jump-start from Kia Roadside Assistance. On 02/26/2026, the vehicle was presented at Moritz Kia Alliance for the same issue. The dealer diagnosed the 12V battery as defective (Code R04) and replaced it under warranty. However, the defect persisted. On 03/10/2026, only 12 days later, the vehicle suffered another total electrical failure. I had to utilize Kia Roadside Assistance for a jump-start and drive the vehicle directly to the dealer without turning the engine off to ensure it could be serviced. This marked the second official repair attempt for this recurring defect. The vehicle has remained in dealer possession since March 10 (21 consecutive days). On March 11, only one day after drop-off, the Service Director threatened that the vehicle would be "impounded" after 60 days, despite the vehicle being the subject of an active Texas DMV Lemon Law Case (#26-0012638.CAF). On March 26, a critical safety failure occurred: during a start-up attempt, the Integrated Power Brake (IPB) system malfunctioned, causing the brake pedal to pulsate and physically "kick back" with significant force against my foot. I have serious concerns that this braking failure could occur while in motion, posing an unreasonable risk of high-speed collision, serious injury, or death. No root-cause diagnosis has been made. Furthermore, the main fuse box cover was left off during service, exposing critical electrical components. The vehicle is available for inspection.

"Continuous engine oil leak for 12 months. After 4 failed repair attempts, the dealer used liquid sealer instead of a gasket. This is a deceptive repair that creates a severe fire hazard. The leak is still active today, March 2026."

The horn stops working when it’s cold and the horn installed does not match the amperage need for the vehicle. It has failed multiple times. I rarely use my horn. It failed for the first time around 20,000 miles. Separately, I have an oil leak that is also covered under warranty. This car has been serviced countless times and it has been in the shop for three weeks.

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.

POWER TRAIN, ENGINE
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.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, ELECTRICAL SYSTEM
Date/time of incident 03-16-2026 18:09-18:17 * Faulting component: Infotainment screen (screen to the right of gauge cluster) * Incident: While backing out of a parking spot and utilizing the cameras to watch my surroundings, the infotainment screen became unresponsive and began flashing between visual noise similar to 'snow' on old broadcast television, primary colored jagged/blocky artifacts, and a black screen. The screen would occasionally revert back to normal imagery but with severely lagging touch response and stuttering screen transitions. This persisted until I pulled over, parked the car, & restarted the vehicle. After restarting the vehicle the infotainment screen flashed: Solid Black -> Solid White -> Solid Red -> Solid Green -> Briefly solid black -> Briefly Solid Green -> Then the infotainment functionality returned to normal operation after a brief stutter. --I have a video of the last portion of this incident that I can share upon request * All camera related safety functionality became unresponsive/unusable during this incident * I've requested an appointment with the local Kia dealership * As this incident just occurred, I have not yet reached out to other parties * No warning lamps or diagnostic warning appeared during or after the incident

Today, my young daughter pressed the button on the inside of the door to close the sliding door. Her hand was still in the way and the door did not stop. Part of her hand was completely closed in the door and she screamed and cried in excruciating pain. Right away I noticed bruising and took her to the ER for an X-ray. Since she is so young, her bones are very pliable and thank goodness the X-ray showed no fracture, just bruising and swelling. The sliding door has previously not stopped for my older daughters as well. This is a major safety issue.

I am submitting this complaint regarding the failure of the Kia Connect telematics system and the cessation of critical navigation support for my vehicle. Despite opening a formal support case with Kia (Ticket #25923650), the following issues remain unresolved: Loss of Trip History (Since January 2026): The Trip History feature within the Kia Connect suite has been completely non-functional since January 2026. This prevents the tracking of vehicle usage, mileage, and driving behavior data, which are core features of the paid subscription service. Failure of Connected Routing & Software Obsolescence: The "Connected Routing" feature is no longer operational. Kia support has stated this is due to the vehicle requiring a navigation update; however, Kia has ceased providing all navigation and software updates for this model as of April 2025. Safety Concern: The lack of software support and the failure of "Connected Routing" forces the vehicle to rely on navigation data that is nearly a year out of date. This creates a safety risk when the vehicle provides incorrect guidance on one-way streets, closed roads, or altered traffic patterns. Furthermore, the persistent failure of these telematics services raises serious concerns about the reliability of the vehicle's emergency communication systems, such as Automatic Collision Notification and the SOS Emergency Assistance button, which utilize the same underlying cellular module and software framework. Corrective Action Requested: I am seeking a mandatory software update from Kia that restores full functionality to the Kia Connect suite (specifically Trip History and Connected Routing) or a final navigation map update to ensure the vehicle’s guidance systems remain safe and accurate for the remainder of the service's lifecycle.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
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.

The driver side passenger door will open by itself when the key fob is near. Today it injured me while pumping gas and almost knocked the gas tank door off and gas pump out. I locked my vehicle to go inside to pay for gas. When I came back to my car to open the gas tank door and inserted the gas pump, the sliding door opened and smashed my wrist in between it and the gas tank cover door. It almost knocked the tank door off but I was able to keep fighting it and pushing it back and it closed. I have deep indents in my wrist and it scuffed the gas tank cover. The sliding doors do not stop when someone is going in or out. It is a safety hazard and should function like a garage door. Stop when it senses something there. I almost lost my wrist today!!!

The contact owns a 2023 Kia Carnival. The contact stated that during freezing weather, the button was depressed to open the driver's side rear sliding door, and the door automatically opened; however, the motor reached a point of resistance and attempted to close the sliding door. Due to the failure of the cable in the door snapped behind the glass window. The contact manually opened the sliding door and used excessive force to close the door. The vehicle was taken to the dealer, who confirmed that the door cable had snapped. The contact was informed that the vehicle was out of warranty; however, the dealer reached out to the manufacturer for assistance. The manufacturer later agreed to partial assistance with the repair. The contact paid for the remaining cost of the repair. The manufacturer was contacted about the repair and provided a case number. The vehicle was repaired. The failure mileage was 63,476.

Horn stops working and needs to be replaced within a year or less. I reported the first time my horn stopped working and it took 4 months until I can have an appointment and order the part. The second time it stopped working was within a year and scheduling an appointment was difficult. I was almost in an accident and unable to use to both to alert the other driver.

ABS was activating inappropriately creating a grinding/pulsating noise while I was attempting to stop at a light. The vehicle did slow down but despite the completely dry road service and sufficient stopping distance, the vehicle never came to a stop and ran into the vehicle in front of me. The vehicle is currently in the autobody shop to be repaired as it is not drivable (leaking fluids). I will be contacting my insurance company and an independent service center shortly to have it inspected. I will also be contacting Kia America, Inc.. There were no warning lamps or symptoms of the problem prior to the failure.

ELECTRICAL SYSTEM
Horns (high and low) have been replaced 5 times under a warranty. This is a serious safety hazard. Vehicle: Kia Carnival (Model Years 2022–2024) Issue: Repeated horn failure / electrical malfunction Owners of 2022–2024 Kia Carnival vehicles are experiencing repeated horn failures that present a safety concern. Reported symptoms include complete loss of horn function, intermittent operation, delayed response, and in some cases random horn or alarm activation without driver input. When the failure occurs, both the high-pitch and low-pitch horns are often found to be inoperative. Many owners report that dealerships replace both horns, sometimes multiple times, with some vehicles requiring second or third replacements. Kia has acknowledged this issue through a Technical Service Bulletin (ELE-263), which instructs dealers to replace both horns when one fails; however, the bulletin does not identify a permanent root cause or corrective design change. As a result, the issue frequently recurs after replacement. A non-functional or intermittent horn significantly reduces the driver’s ability to warn other road users and avoid collisions, creating a clear safety risk. Given the recurring nature of the failure across multiple model years, this appears to be a systemic defect rather than isolated component wear.
