Just leased an 08 SS

Sounds like the gears are bad in one spot. You can try to guide it closed with someone helping you as you pull or push it into place. Otherwise: http://www.theautopartsshop.com/auto+car-usa+parts/chevrolet+monte-carlo+sunroof-motor.html

I actually took a 06 Commander in last week with the same problem. We checked the windshield carefully, and then drivers door moldings and then blew out the drains for the sun roof.
It still leaked down through the drivers' side drain line area of the sun roof, around the window moulding, and dripped right in the vicintiy of the rear of the radio.
We finally found the problem by dropping the head liner down and using an inspection mirror with a flash light. We disconnected the drain line and plugged the nipple opening and poured a small amount of water into the sun roof pan and located a hole in the drain pan just above where the nipple is formed for the drivers' side sun roof drain line.
We could not see the actual leak source without the mirror and flashlight, as it was on the interior side seam facing away from the drivers' door opening.

Since carefully sealing the drain pan seam just a 1/4 above the drain hose nipple on the interior side, slightly above where the drain hose connects, the problem appears to be solved.

It appears to be a manufacturing defect in the plastic seam in my opinion. Could just be a faulty radio if your car doesn't have a sunroof, or a leaking windshield gasket.

The A service and B service is an oil change and a long list of inspections. Unless the service is covered under warranty, or this is a new car and you want some piece of mind, I suggest only getting the oil change. The rest of the "service" consists of someone looking for problems with your car. Here's what's included:

may have slipped on the track mechanism and needs adjusted custom car shop may help with this..good luck..

my apologies for delay in getting back to you.only just sorted this.turned out was the little control unit for sun roof causing problem.it is cable tied to the sun roof frame beside the sun roof motor and can only get at it by dropping the head cloth on one side.learned from a hyundi dealer the switches give a lot of bother,now and again the control units do too.many thanks.

a creative solution is to use velcro tape. a piece on the visor and a matching piece on the roof liner

Yes Mercedes Definetily offers a lease program for them, HOWEVER, the dealers will try to push for you to lease a New-they will say cheaper-believe it IS NOT you can save Big Bucks going with a Brand Spanking Used Lease. Good Luck

Apple leasing was great and I highly reccomend them. I started talking with National Vehicle Leasing. They offered a lower monthly price but th lease term is 60 months which they try to hide, obfuscate and misrepresent in every way possible.
