The failure pattern owners describe
Owners describe a cluster of serious electrical and safety defects affecting the 2022 Carnival across multiple systems. The sliding door pinch sensor fails to detect obstacles in the closing path, resulting in the door slamming shut on fingers and bodies—one owner reported a laceration requiring surgical repair. A recall and software update in May 2023 addressed door speed and beeping but did not fix the sensor sensitivity. Owners report that the sensor only responds when pushed from inside the vehicle at a specific angle, not when an external object blocks the door.
In cold weather (15–19°F), the throttle body freezes, forcing the vehicle into limp mode with a maximum speed of 10–14 mph regardless of warm-up time. Multiple owners report this issue; dealerships blame condensation entering the throttle body but simply delete the check engine code rather than repair the fault.
Instrument cluster screens fail intermittently or permanently, leaving drivers unable to see the speedometer, fuel gauge, gear indicators, or warning lights—a hazard at night when gear position is invisible. The horn stops working intermittently with no warning and no pattern; one owner reported it sounding abnormal (like a "clown horn") before total failure. The fuel door jams with no manual override, leaving owners stranded. The rear liftgate repeatedly slams shut, striking occupants. Owners report dealerships claim they cannot reproduce problems or refuse to perform repairs.

Failure modes owners describe
Sliding door pinch sensor failure / inadequate obstruction detection
The door's safety sensor that should stop and reverse the door when an object is in its path does not reliably detect external obstacles. Owners report the door closing fully on hands, fingers, arms, and bodies without stopping. Some owners note that the sensor only responds when pushed from inside the vehicle in a specific manner, not when an object blocks the door's path from outside. The recall and software update addressed door speed and beeping but did not fix the pinch sensor sensitivity.
When: Ongoing from early ownership; recall attempted in May 2023
Symptoms owners cite: Door closes completely on fingers, hands, arms, body without stopping; Door does not detect external obstacles in closing path; Sensor only responds to internal pushing from specific angle; No reversal when object placed in external closing path; Causes laceration and crush injuries to occupants
Repairs/costs cited: Recall service and software update performed but did not address pinch sensor sensitivity. Door actuator replacement cost cited at $2000+ for related rear liftgate issue.
Recalls/TSBs owners mention: Recall service completed May 2023 with software update to door speed and beeping; pinch sensor sensitivity was not adjusted despite owner request
Throttle body freeze in cold temperatures
The throttle body sticks or freezes in cold weather (15–19°F), causing the vehicle to enter limp mode and limiting acceleration to 10–14 mph regardless of warm-up time. The vehicle will not shift properly and produces a check engine light. Dealers attribute the failure to condensation or moisture entering the throttle body, but owners report this is atypical for their experience with other vehicles. Multiple owners report the same issue.
When: Cold weather operation (15–19°F); occurs early in vehicle operation
Symptoms owners cite: Vehicle cannot accelerate above 10–14 mph; Limp mode engagement; Inability to shift properly; Rough idle with deep exhaust noise or low RPMs; Check engine light illumination; Vehicle shudders during warm-up
Codes mentioned: P2118, P211800
Repairs/costs cited: Dealership deleted check engine code without repair in one case; attributed to condensation in throttle body. No permanent fix confirmed in narratives.
Instrument cluster display failure
The instrument cluster screen malfunctions, either intermittently or permanently, and fails to display critical information. Owners report inability to see the speedometer, fuel gauge, gear position indicators (P, R, N, D), and check engine warning light. At night, the lack of gear indicator lighting creates a safety hazard. Diagnostic testing at dealership showed no fault codes despite clear visual evidence of failure.
When: Occurs around 9,000–80,000 miles; can become permanent
Symptoms owners cite: Climate control button lights not illuminating; Gear shift indicator lights not illuminating (P, R, N, D); Current gear display lights not working; Speedometer not visible; Fuel gauge not visible; Check engine light not visible; Intermittent failure progressing to permanent outage
Repairs/costs cited: Dealership diagnostic testing showed no faults despite clear visual evidence of failure; no repair attempted
Horn intermittent failure
The horn stops working intermittently and unexpectedly, with variable outage duration. Restarting the vehicle does not resolve the issue. One owner reported the horn produced an abnormal sound (described as a 'clown horn') before complete failure of one of two horns. The failure may be related to moisture or temperature sensitivity.
When: Intermittent failures occurring throughout vehicle operation
Symptoms owners cite: Horn does not sound when pressed; Intermittent function with inconsistent outages; Restarting vehicle does not restore function; Abnormal sound before failure (clown horn description); Safety hazard from inability to warn other drivers
Repairs/costs cited: One horn replaced under extended warranty with deductible; issue not permanently resolved for some owners
Recalls/TSBs owners mention: Partial repair covered under extended warranty with deductible
Rear liftgate power door failure and malfunction
The rear power liftgate opens to the desired height, then slams back down partway (1/4 to 1/2 of total height) repeatedly. The problem persists even when auto open/close is disabled and when the door is manually pushed to the open position. The repeated slamming has caused repeated head, arm, and hand injuries to occupants.
When: Occurs during normal liftgate use
Symptoms owners cite: Liftgate opens partially then slams down; Malfunction repeats with each use; Occurs regardless of auto open/close setting; Occurs during manual push to open; Strikes occupants in head, arms, and hands
Repairs/costs cited: Door actuator replacement quoted at $2000+
Fuel door stuck / no manual override
The fuel door will not open and has no manual override or emergency release mechanism. The vehicle cannot be refueled, leaving the owner stranded. This is identified as a design/system failure rather than owner negligence.
When: Occurs mid-use
Symptoms owners cite: Fuel door will not open; No manual override available; No emergency release mechanism; Vehicle unable to be refueled
Sliding door unintended closure
The sliding door closes on its own or closes rapidly without the owner pressing the door close button. The condition is associated with the sliding door lock being engaged. When the lock is on, the door may slam shut; when the lock is off, the door still closes on its own without normal operation.
When: Occurs when vehicle is parked, particularly on slopes
Symptoms owners cite: Door closes without button press when lock is on; Door closes rapidly or slams shut; Door closes on its own when lock is off; Abnormal closing behavior
Transmission failure and drivability issues
Transmission failed at 11 months of ownership (February 2023) and was replaced under warranty. After transmission replacement, the vehicle shakes violently when accelerating, loses power on acceleration, and the self-driving mode activates on its own. Dealerships report they cannot duplicate the problems and refuse to repair. Front axle popping noise was also replaced but reappeared in both front and rear.
When: Popping noise from day one; transmission failure at ~11 months (February 2023); post-repair drivability issues ongoing
Symptoms owners cite: Front axle popping noise present from new; Popping noise in front and rear after axle replacement; Transmission failure; Violent shaking during acceleration; Loss of power during acceleration; Self-driving mode activates unintentionally; Dealerships unable or unwilling to diagnose repeating problems
Repairs/costs cited: Front right axle replaced early in ownership; transmission replaced in February 2023
Electrical system damage and battery drain
Unspecified electrical system fault has caused damage to two batteries (owner paid for both), fuel pump damage requiring line cleaning, blown fuses, and failure of the horn. The owner estimates approximately $1,000 in out-of-pocket repairs on a new vehicle. The root cause is described as an electrical problem.
When: Early in vehicle ownership
Symptoms owners cite: Multiple battery failures and damage; Fuel pump damage; Blown fuses; Horn non-functional; Excessive electrical system drain
Repairs/costs cited: Battery replacement (×2), fuel pump line cleaning, fuse replacement; owner paid ~$1,000 out of pocket
Engine misfire and shuddering
The engine misfires during driving and shudders during warm-up. A check engine light illuminates. The vehicle was diagnosed multiple times with the same failure but not repaired despite manufacturer notification.
When: At 9,000 miles
Symptoms owners cite: Engine misfire; Vehicle shudders during warm-up; Check engine light illumination; Issue repeats across multiple diagnostic visits without resolution
Repairs/costs cited: Multiple diagnostics performed; failure identified but not repaired
Recalls/TSBs owners mention: Manufacturer notified; no corrective action documented
Engine failure with fire and smoke
The engine developed a smell of fire and fuel, produced smoke, and subsequently would not start or run. The owner heard a popping noise while driving before the engine died completely. The vehicle is disabled and has had multiple unspecified issues since new.
When: After several other electrical and mechanical issues
Symptoms owners cite: Smell of fire and fuel; Smoke from engine; Popping noise during driving; Complete engine failure; Vehicle will not start

What owners are reporting 3 most recent
Fuel door will not open, there is no manual override, vehicle cannot be refueled and since there is no emergency release it caused me to be stranded at a gas station at night with my 4 kids which is a huge safety concern and should be taken seriously as this is a safety and drivability issue that I should not be held responsible to pay for when it is at no fault to me it is a design/system…
The dealer is attempting to classify the torn rubber and pulled-out wiring as “non-recall wear and tear,” but the damage is a direct result of: a latch that sticks, a door that does not close smoothly, a malfunctioning power sliding mechanism, and the repeated force required to compensate for the defect. Under recall law, when an unresolved defect causes additional damage, the owner cannot be…
The safety feature on the sliding back doors is not safe for children. Previous vans I have owned had a sensor that would trigger the door to open back up if it were closing and ran into something, like a child getting caught in the sliding door. I am a grown adult and the door closing on the Kia Carnival is too strong for me to even stop with my entire body weight. A child is going to get…
