VIBRATION/CHATTER WHILE OPERATING
2011 Sorento (XMa) Panoramic Sunroof Glass Vibration/Chatter while Operating
On 2011 Sorento (XMa) model vehicles, built prior to March 24, 2010 and equipped with
Panoramic Sunroof Option, the Sunroof Glass can vibrate causing a chatter sound during
operation. If you encounter a customer vehicle with this concern, a lack of lubrication at the Sunroof
Track Channel could be the cause.
First, inspect the Sunroof Channel for any binding or broken parts (repair as necessary). Open the
Sunroof completely and use shop air to blow out any foreign material or dust build up. Inspect the
Sunroof Track Channel for proper grease application. It is possible, that the grease has not
throughly spread to lubricate the entire track channel. A simple step of applying a generic brand
silicone lubricant such as SIL-GLYDE will solve this issue. Make sure you use an adequate amount
to completely lubricate both right and left track channels. Operate the sunroof by opening and
closing several times to spread the applied grease throughout the channel.
