Problem solved and a new question for you folks.
2012 CLS 550, purchased last September. I love it. Shortly after buying the car I mentioned on the forum that I had a loud rattle in or near my sunroof. The dealership is not close to home so it took a while to take it in. It seems roof rattles are difficult to track down. They couldn't solve the problem that day so gave me a loaner and spent a significant amount of time to find and replace a stripped bolt. No more rattle and I am pleased. I hate rattles.
New question about another noise. I start the car and drive away. Within 10-20 seconds of driving there is a soft, low pitched thump from the rear of the car. Smooth road; I'd not hitting a bump. This happens almost every time I drive and happens only once during that trip. Strange. I can't tell if it's in the exhaust or suspension or whatever. I can find nothing loose that is shifting and the car handles beautifully. Any suggestions? If the dealer weren't over 2 hours away I'd drop by and ask them.
