2022-2025 Kia Carnival Sliding Door Guide: Recalls, Latch Failures, and Repair Costs

Known Issues, Recalls, and Investigations for 2022-2025 Carnival Sliding Doors

The power sliding doors on the Kia Carnival have been the subject of multiple safety recalls and investigations. It is critical for owners to check if their vehicle is affected.

NHTSA Recall 23V-783: Sliding Door May Not Latch

In late 2021, Kia recalled 2,956 model year 2022 Carnivals due to a defect in the passenger-side power sliding door. The issue stemmed from improperly manufactured plastic holders within the door's remote controller assembly. This could cause the latch to stick in the open position, preventing the door from securing properly. The remedy for affected vehicles is the replacement of the sliding door release actuator's drum and holder at a Kia dealership, free of charge. Warning signs include four audible chimes and a 'door-ajar' warning on the instrument cluster when the door fails to latch.

Software Recall for Auto-Reverse Function

In April 2023, Kia issued a recall for over 51,000 2022-2023 Carnival minivans to address concerns with the power sliding door's auto-reverse feature. This followed an NHTSA investigation (PE22-004) into complaints that the doors required excessive force to stop and had caused injuries. The recall fix is a software update for the power sliding door control module. This update adds two warning chimes when the door starts to close and slows the door's speed as it approaches the latching point to reduce the risk of injury.

Owner Complaints and Class Action Lawsuit

Beyond official recalls, owners have reported numerous issues on forums. These include doors that fail to open or close, shuddering, making grinding noises, or not registering as closed. Some of these issues have led to a class-action lawsuit alleging that the doors can still close with dangerous force even after recall-related repairs.

Symptoms of a Failing Sliding Door Assembly

Diagnosing a sliding door issue involves observing its specific behavior. Different symptoms often point to different failed components.

1. Door Beeps and Fails to Open or Close

If you press the button and the door moves slightly, beeps, and then returns to its starting position, this often points to a problem with the power sliding door motor or its internal sensors. The control module may be detecting an obstruction or a fault in the drive mechanism. A diagnostic scan can reveal trouble codes like B14A7, which indicates a sensor circuit problem.

2. Grinding, Scraping, or Shuddering Noises

Loud grinding or scraping sounds during operation are a classic sign of a failing roller assembly 🎬 Watch: How to identify and fix door shuddering and noise or a problem with the motor's drive cable. The small wheels on the upper, middle, or lower rollers can wear out, develop flat spots, or seize, causing the door to drag along its track instead of rolling smoothly. A damaged drive cable inside the motor assembly can also create significant noise as it binds or frays.

3. Door Does Not Latch or Appears Loose

If the door slides fully closed but fails to 'pull in' and latch, or if it pops back out slightly, the issue is likely with the latch assembly itself or its alignment. This will typically trigger a persistent 'door ajar' warning on the dashboard. This was the primary issue addressed by the 2021 recall.

4. Power Function Works, but Manual Operation Fails

In some cases, owners report that even after turning the power sliding door function off, the door cannot be unlocked or opened manually. This indicates a failure within the mechanical linkage between the handle and the latch, separate from the electric motor.

Buying a Used Carnival Sliding Door Assembly

Given the high cost of new components and dealer labor, a used OEM part can be a cost-effective solution. However, careful inspection is key.

Why Used OEM is Often the Best Choice

For a complex, safety-critical system like a power sliding door, original equipment manufacturer (OEM) parts are highly recommended. Fitment, electronic compatibility, and material quality are guaranteed. As of early 2026, the aftermarket for complete Carnival sliding door assemblies is virtually nonexistent, making used OEM the primary alternative to expensive new parts.

Inspection Checklist for Used Parts

• Verify the Part Number: The Carnival uses different parts for the left and right doors, and for the upper, middle, and lower roller positions. It is absolutely essential to match the OEM part number from your old part to the used one you are buying. Do not rely on visual comparison alone.
• Inspect Rollers: If buying a roller assembly, check the condition of the small wheels. They should be round, free of cracks or significant flat spots, and spin freely without a gritty or binding feeling.
• Check the Motor Assembly: If buying a motor, inspect the housing for any cracks or signs of damage. Look closely at the electrical connector for corrosion or bent pins. Ask the seller about the mileage of the donor vehicle if possible.
• Examine the Latch: Look for any cracks in the plastic housing or bent metal components. If possible, manually actuate the lock mechanism to ensure it moves freely.

Cost of Replacement

Repair costs for the Carnival's sliding door can vary dramatically depending on the failed component and whether you use a dealer or perform the work yourself.

Note: Prices are estimates as of early 2026 and can vary. Shop labor is based on a typical rate of $120-$180/hour. A single repair involving multiple issues could be significantly more expensive, with some dealer quotes reportedly reaching several thousand dollars.
