What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

All generations of Carnival power sliding door systems are prone to motor failure, roller wear, and track debris causing doors to stall mid-travel, refuse to open or close, or slam shut unexpectedly. The motors are underpowered for the door weight in later KA4 models. Roller assemblies crack and seize. Child-safety implications when doors behave unexpectedly. The fault affects both left and right doors independently and is among the most consistently reported issues across all Carnival generations on owner forums.

What you would notice

Sliding door stalls or stops mid-travel
Door refuses to open or close via button or remote
Grinding or clicking noise from door track during operation
Door closes too slowly or reverses unexpectedly
Error message or warning chime related to sliding door

How to check it

Where to look. Left and right B-pillar and door track area; motor located inside door panel at rear

Operate both sliding doors multiple times via interior button, exterior button, and key fob.
Listen for grinding or hesitation.
Inspect the lower door track for debris, corrosion, and roller condition.
Check motor connector for corrosion.
Attempt manual override to assess mechanical resistance.

What it costs to put right

$450 to $1,100 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Have the sliding doors ever failed to open or close properly?”
“Has either sliding door motor been replaced?”
“Have the door rollers or tracks been cleaned and lubricated recently?”
