Hi, I am new to this forum and recently I have gotten some Ideas from another MB forum that some of you probably post on. I just want to try to get all of the ideas that I can. Three months ago I purchased a new, 2003, S55 in Houston Texas. I live quite a distance from Houston. There are dealers in Tyler and Dallas that are much closer to me. My new car will not hold a battery charge. In the three months that I have owned it, and I was gone 3 weeks of that time, it has been jump started 6 times. It will not start now so the 7th time is coming. Two of the times the car was unmoved for 2-3 weeks. Four of the time it sat for 2-3 days and the car is not starting today and it was driven yesterday. I have taken the car to Tyler and they replaced the battery, which did no good. I have an appointment next week in Dallas and I know they need to see if there is a short circuit to the battery or if there is an electrical problem. Would you please tell me what you think and what I might ask this well-established Mercedes dealer in Dallas. I want to know what they do instead of sitting in a waiting room. Do they just push you in the room to get rid of you. I know the dealer in Tyler just replaced the battery quickly and charged Mercedes and got rid of us. They told us to drive the car for 30 minutes every 2 days. I don't drive that car that often, but I sure think it should start when I want to drive it. Any Ideas and Thanks so much.
