UPDATE #2: It's BAAAAaaack! One year old now and it started doing it again... right after getting the remotes reprogrammed and a couple of dealer selectable options turned on.

UPDATE: The following issue resolved itself with no intervention from myself or the dealer after about 4 months.

I have the 6-Disc Changer model.
More often than not, when I get in the car and start it up, the volume on the stereo cannot be heard. I can't get any sound out of it until I turn it off and then back on. I play it loud 'cause it sounds so good and was thinking there may be some feature that relates to not blasting your ears out when you first get in, but can find no info on it in the manual. I have tried leaving it loud and soft and at several specific settings, but can find no way to recreate the problem with any consistency. Any thoughts?

 

my car does the some thing but know i just turn the radio off when i turn off the car and when im not gonna us it and then i turn it back on when i turn on the car or when im gonna us it thats all i can say good luck with that

 

Have you inquired about it being a dealer programable option? For instance volume = off on startup, vs volume = last on startup.

 

Hum I don't have this problem with my radio or CD player. Matter of fact I haven't had any real problems with the car but then again I only have 200 miles on it and it is a month old.
