Why won't my Kia Carnival sliding door close?

Short answer: Most often the door thinks something is in the way. The power sliding door has a pinch sensor in the rubber strip, and owners found a weatherstrip that had popped loose at the bottom was enough to make it reverse. Kia also has two door recalls on these vans. One replaces parts in the passenger-side latch controller on 2022s (21V908). The other updates the door software so it reverses properly (23V236). If your van is part of these recalls, the dealer fixes it for free.

Symptom: The sliding door opens fine but beeps and won't close, backs off right before latching as if something is in the way, works only with the engine running or a front door open, or gets stuck open.

What to check first

1. Run your VIN for recalls 21V908 and 23V236.
2. Look along the door's rubber weatherstrip, especially at the bottom, for a section or clip that has popped loose. Owners pushed it back in and the door closed.
3. Clear the track and check for anything rubbing near the latch.
4. Use the power-door off switch (owners found it by the driver's left knee) to close the door by hand if you're stuck.
5. Don't force it. One owner said forcing the door snapped the door cables.

Likely causes

1. Loose weatherstrip or pinch strip triggering the obstacle sensor. Owners found a loose strip or a missing clip at the bottom of the seal.
2. Passenger-side latch controller (recall 21V908, 2022). Kia says the remote controller may stop the door from latching securely. Dealers replace the release actuator's drum and holder.
3. Door software (recall 23V236). The auto-reverse feature may not activate in every situation. Dealers update the door control module software. An owner said the update also makes the doors beep and close slower.
4. Worn door motor, cables or pinch strip. Owners describe replaced door motors, snapped cables and pinch strips.

What it usually costs

The recalls are free. One 2022 owner out of warranty, whose van wasn't covered by a recall, said repeated door repairs cost thousands. Reseating a loose weatherstrip costs nothing.

Is it safe to keep driving?

Yes, if the door closes and latches. A door that won't latch or close shouldn't be driven with passengers next to it. Use the manual switch to close it by hand or have it towed. Verify with a mechanic or dealer.

DIY or shop?

DIY: check and reseat the weatherstrip, clear the track, and use the manual switch. Dealer: recalls, motors, cables and pinch strips.

Recalls, bulletins and complaints in plain words

• Recall 21V908 (Kia SC221; 2022 Carnival): the passenger-side power sliding door remote controller may malfunction, so the door may not latch securely. Dealers replace the release actuator's drum and holder. Recall 23V236 (Kia SC266; all 2022 and some 2023 Carnival): the sliding door auto-reverse may not activate in every situation. Dealers update the door control module software. If your van is part of these recalls, the dealer fixes it for free.

What owners report

• In 2022 Sliding Door Issue on Carnival Forums, a 2022 owner's right sliding door opened but just beeped and wouldn't close, even after Kia's reset steps. One owner said the rubber along the door would pop out slightly and the door closed once it was pressed back in. Another had both door motors replaced. A member said the door recall made the doors beep and close more slowly. A later owner said the passenger door wouldn't shut after the recall and the dealer wanted to charge for it.
• In Sliding door will not close, intermittent issue on Carnival Forums, an owner's passenger door kept backing off right before it latched, sometimes a dozen times in a row, and closed fine with the engine running or the front door open. Members pointed to the power-door off switch by the driver's knee for closing it by hand. A 2024 owner found the weatherstrip loose at the bottom with a clip out, and a 2022 owner out of warranty warned that forcing the door snapped its cables.

My take

My advice as a former lot tech: before anyone touches a minivan door motor, run a hand along the whole seal. A popped-out strip is the cheapest fix there is, and pinch sensors are touchy.

Vehicle focus: 2022–2023 Kia Carnival with power sliding doors.

Safety / mechanic note

A sliding door that does not latch or reverse properly can injure passengers. Verify with a mechanic.
