All right, I understand it's freezing outside and that metal contracts when it's cold, but has anyone else ever had their spoiler squeak when it deploys? It just started happening when it got really cold outside. If anyone has the same problem or a solution, please let me know.

 

You might have to lube the linkages on the spoiler. I'm not sure what MBZ recommends but I would try and use a light weight mineral or penetration oil. Might just have a light rust coating on a bearing surface from water moisture.

 

Do a search there is thread about lubricating the gear assembly behind the rear panel in the trunk.

 

you need some krytox lubricant - -Mopar part#5019059aa. Then lube the motor bearing behind the electrical connector and also lube the gear wheel shaft and the gear wheel shaft bearing.

 

Maybe you have a rodent problem?
