On test driving a few SLS yesterday, I noticed such a rear squeak in all of them. Hope it is nothing significant as I bought one.

Well, went to the dealer's service center today. They looked at it for a while, kept it running and couldn't duplicate it UNTIL they started driving it back to its outdoor spot. Then the radio went out on them too. They are ordering a new radio. Not sure about whether it could rather be the amp but ...

Is there an anti-theft feature on the radio which cuts it out after ten minutes? Just bought an SLS today and was disappointed that the radio kept cutting out. Restart the car, the radio works for ten minutes.
