What goes wrong
The W639 Vito sliding door mechanism suffers from progressive wear of the lower, centre, and upper rollers along with the guide rail components. On electric-door variants, the cable connecting the motor to the door latch mechanism is made from relatively weak materials and stretches or snaps over time. Manual-door variants suffer from seized or corroded rollers and cracked plastic guide hinges. In both cases the door becomes heavy to operate, fails to latch properly, drops on its runners, or stops mid-travel. Replacement kits with improved materials are widely available from aftermarket suppliers.
What you would notice
- Sliding door stiff, heavy, or requiring excessive force to open or close
- Door fails to latch securely or pops open while driving
- Grinding or scraping noise during door travel
- Electric sliding door stops mid-travel or reverses unexpectedly
How to check it
Where to look. Rear sliding door — lower guide roller, centre and upper guide hinges, guide rail, and electric actuator cable
Open and close the sliding door several times and note any stiffness, grinding, or failure to latch.
Inspect the lower guide roller at the base of the door opening for cracking, seizure, or corrosion.
Inspect the upper and centre guide hinges for cracked plastic.
On electric-door models, check the guide rail for a worn or frayed cable and test door response at low and high temperatures.
What it costs to put right
$400 to $1,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Does the sliding door open and close smoothly and latch securely every time?”
- “Have any rollers, guide rail components, or door cables been replaced?”
- “Has the door ever dropped, jammed, or failed to latch while driving?”
