Saw some old posts on this problem which appear to have dealt with earlier model years. So, I wanted to refresh the question. This is not a subscription issue. I get all Sirius channels, although I am not signed up for premium. I'm still in free period.

Bought 2011 E-Class in July. Sirius has never worked - choppy reception, many "no service" messages. Wife drives a Lexus with XM Radio - absolutely no problems. Saw from previous messages that I would need to have dealer fix it. Drove to dealer - had more than 30 interruptions with more than 10 "no service" messages on the way. Dealer kept car for two days and drove it around. Told me everything was fine, which I knew could not be true. Dealer was unaware of any known Sirius problems. Dealer said that software was reloaded. Drove it home on same route and experienced the same awful reception. Now I'm keeping a log.

For the previous posts, I understood this to be a Sirius equipment problem. Any suggestions?

Thanks

 

Wow...finally an easy one to answer.

Drive your car to the dealers location (don't go in). Then make believe you are on a test drive and find a short route where your radio doesn't work a few times. Drive that route a couple of times to make sure you lose signal in the same places.

Then actually go to the dealer..and ask your salesman if you could do a test drive in another car to see how sirius works, because you are having a problem with reception in your car. Take the test drive car on the same route....see if it drops at the same places. If yes, well, then maybe they all do it and you're in a lousy area with lots of trees.

If the test drive car works fine and doesn't drop out....now you are ready for the service manager to take a drive with you in your car and in the test drive car. Demo that one works and yours doesn't.

Sounds like a lot of work....but it isn't...and it stops the dealer from saying they all do it.

Good luck

Note: I am not sure about the buffering in Sirius vs XM. I seem to lose Sirius more in my 2011 e then I lost XM in my 2011 Infiniti....so it is possible that the dealer is right and they all do it. XM might just work better than Sirius (although they are now the same company, they use different antennas and have different broadcast technologies).

 

Thanks much for the suggestion. What I am doing now is keeping a log for 30 days detailed by street. I make entries into a voice recorder while enroute and later transcribe them to a written log. Then for my next visit I will have that. So far, the receptions have been overall poor, but on some days it is surprisingly good. I don't believe weather shoud affect the reception. In addition, I plan to take a Mercedes service manager for a ride to confirm the performance. I like your idea of finding a reliable bad sport first.

 

thats weird I havent had any problems with mine yet.... seems the same as my c class was

 

I have a 2009 E 350 with the same problem. I have had it since the free period and now when I am not. I bought mine in July too and I drop the signal frequently in certain areas on the wide open highway... dealer told me the same thing. I might try that solution from the previous poster...

 

As a follow-up, it turned out that there was something wrong with the car's antenna. It was replaced by the dealer. Have had no problems since. The maintenance team was impressed with my log. Apparently, there was a service notice about the problem. I'm now a happy camper.
