Both the sliding doors make a grinding noise when opening or shutting down.

The place I take this to for an oil change claims to lubricate doors and windows. Now I am not too sure.

What level of knowlege do I need to fix the grinding noise? My mechanical skills are very limited to changing a flat tire and the wiper blades on my van.

Edited: The car is no longer under warranty. I have a power-train warranty and I am not sure if it covers doors.

Are the doors motorized or manual? – Mark Johnson Apr 16 '14 at 17:51
@MarkJohnson ... I'm sure since it's a 2012, they're both motorized. – Pᴀᴜʟsᴛᴇʀ2 Apr 16 '14 at 18:16
They are motorized. I can control them from the switch on the keypad as well. – abhi Apr 16 '14 at 18:17
Is this thing still under warranty on the Bumper-to-Bumper? If so, take it back to Dodge and have them fix it. These should not be grinding. – Pᴀᴜʟsᴛᴇʀ2 Apr 16 '14 at 18:17

The maintenance schedules says At Each Oil Change:

Open the left and right door (slowly) and inspect for excessive dirt. 
If noise exist wipe clean and apply krytox lube to the door rollers.

Not sure if that's referring to the front driver/passenger doors or the sliding doors. I would break out the Mark I eyeballs and see if you can see any sign of lubrication and maybe apply some fresh Krytox to the moving parts and friction surfaces. Of course, your problem could actually be grease contamination in the motor clutches, in which case more grease could just make it worse. Possibly there could be some debris contamination, too.

Visual guide for reference.

See, this is why you need to answer more often, Mark ;-) – Pᴀᴜʟsᴛᴇʀ2 Apr 16 '14 at 18:44
@Paulster2 With the warmer weather, I've been working on vehicles. I guess it has me fired up to solve problems. – Mark Johnson Apr 16 '14 at 19:14
Mark, Thank you for taking the time to answer. I am planning to get the vehicle inspected for tire-wear. At that time, I will ask the mechanic to check for the sliding doors. – abhi Apr 16 '14 at 21:35
@abhi Somebody that sees a lot of Dodge Caravans would probably be a good choice. – Mark Johnson Apr 16 '14 at 21:36
@abhi Don't forget to report back with an update to help those who wander in here from Google – Mark Johnson Apr 16 '14 at 22:07
