Kia Carnival Common Problems

ELECTRICAL SYSTEM

Owners report frequent issues with the 2025 Kia Carnival's electrical system, primarily involving unexpected battery drain and dashboard malfunctions. Complaints commonly mention the 12-volt battery discharging rapidly, often leaving the vehicle inoperable after being parked for a few days. Additionally, multiple owners describe experiences where the dashboard and interior lights unexpectedly turn off while driving, posing potential safety risks due to loss of visibility. These issues appear in vehicles with varying mileage, including those with as few as 300 miles. Some owners also report problems with the Body Domain Controller and other electronic components, which can render the vehicle unsafe or unsuitable for normal operation.

STRUCTURE

Owners report that the 2022 Kia Carnival frequently experiences issues with its power sliding doors, which do not stop closing when encountering an obstruction, leading to injuries such as bruised limbs. Complaints often describe the doors requiring excessive force to stop, and there is mention of inadequate sensor performance. Additionally, there are reports of the liftgate strut failing, causing the liftgate to drop unexpectedly, posing a risk of head or neck injury. These issues are typically noted early in the vehicle's life, with some occurring at mileage as low as 500. Safety implications include potential injury to passengers, particularly children, as well as risks associated with the liftgate unexpectedly closing.

UNKNOWN OR OTHER

Owners of the 2022 Kia Carnival frequently report issues with the power sliding doors, specifically that they do not reverse or stop when encountering an obstruction, resulting in injuries to children and adults. Complaints describe the doors closing with significant force, failing to detect hands or arms in their path, even after a recall intended to slow door speed and add warning beeps. Additionally, several owners report unexplained windshield cracking and incidents involving air conditioning leaks leading to mold growth. These issues are noted in vehicles with varying mileages, with some incidents occurring as early as 8,000 miles. Safety implications include injuries from door malfunctions, and in one case, a reported crash. This information is relevant for potential buyers considering the vehicle's safety features and reliability.

ELECTRICAL SYSTEM

Owners report several electrical issues with the 2022 Kia Carnival, with a significant number of complaints focusing on malfunctioning sliding doors and horn failures. Symptoms include sliding doors closing unexpectedly or not reversing when obstructed, and horns intermittently failing to work, which presents safety risks in alerting other drivers. Complaints frequently mention problems with the vehicle's throttle control in cold temperatures, leading to reduced acceleration and "limp mode," with some reports occurring around 9,000 miles. Safety implications are notable, with injuries reported from door malfunctions and potential hazards from throttle issues. These patterns suggest potential concerns for buyers considering this model, particularly regarding electrical reliability and safety features.

POWER TRAIN

Owners report several issues with the 2025 KIA Carnival's power train, primarily involving the vehicle's inability to accelerate beyond approximately 30-31 mph and unexpected gear shifting. Complaints frequently mention that the vehicle loses power, particularly in cold weather, and often requires restarting to temporarily resolve the issue. Additionally, some owners describe problems with the gear shifter indicating incorrect gears, leading to potential safety risks, such as unintended vehicle movement. These issues are noted across various mileage ranges, including vehicles with as few as 3,000 miles. Safety implications include the risk of collision due to the inability to maintain or reach safe speeds in traffic, though no crashes are explicitly reported. Buyers should be aware of these recurring issues, particularly in hybrid models and in colder climates.

UNKNOWN OR OTHER

Owners of the 2025 Kia Carnival frequently report issues related to unexpected deceleration, with multiple complaints describing the vehicle not accelerating beyond approximately 30-31 MPH. This issue often resolves temporarily by restarting the vehicle, but it poses safety risks, especially when merging onto highways. Several reports also mention problems with the rear entertainment system and distracting driver alerts prompting unnecessary breaks, which cannot be disabled. Additionally, there are concerns about the sliding doors failing to detect obstructions, resulting in potential injuries. These issues are observed at low mileages, with some occurring as early as 600 miles, indicating potential early-life reliability concerns for prospective buyers.

UNKNOWN OR OTHER

Owners report several issues with the 2023 KIA Carnival, primarily involving the vehicle's gas door actuator, sliding door sensors, and metal seat railings. Complaints frequently mention the gas door failing to open, which prevents refueling, with some owners experiencing this issue multiple times. Additionally, multiple owners describe the sliding doors not reversing upon encountering resistance, posing a risk of injury, particularly to children. The metal rails where seats connect are reported to become extremely hot, with one owner noting a child suffered a blister. These issues appear across various mileage ranges and usage timelines, with some vehicles being relatively new. Safety implications include potential injury from the sliding doors and hot rails, and concerns about fuel leaks and persistent odors in some cases.

VEHICLE SPEED CONTROL

Owners report that the 2025 KIA Carnival frequently experiences issues with vehicle speed control, particularly in cold weather conditions. The most common symptom described is an inability to accelerate beyond 31 MPH, despite the engine revving and the accelerator being fully depressed. This issue often resolves temporarily when the vehicle is turned off and then back on. Several complaints mention that these problems occur at low mileages, sometimes as early as 1,500 miles, and can pose significant safety risks when merging onto highways or navigating busy streets. Additionally, one report describes unintended acceleration from a stop, though this is less common.
