2003 Mercedes-Benz SL500 Owner Comments

My Mercedes 2003 SL500 developed banging noise in the gas tank, in January 2010, having about 18,000 miles, prompting me to call the dealer. I was told that the baffle broke off and couldn't be fixed, advising me to replace the tank for $2,500. I argued that it was an obvious manufacturing defect considering the low miles and requested a free tank replacement, but I was refused on the grounds that the warranty expired. I couldn't believe what I heard, did some research and discovered that early models in 2003 and 2004, had similar tank problems and were replaced with a better design later. But, I was not informed about it. Furthermore, I found out that many other owners from that time had the same problem as I did. I waited for a while to see if Mercedes corporation would recall the early models, kept the gas tank full to avoid the annoying noise (the broken baffle cannot float and bang when the tank is full) and when I got convinced that Mercedes would not do anything for the victims I decided to file this complaint. It is a shame that a manufacturer wouldn't want to correct their own mistakes, considering a $100,000 price tag that I paid. What happened to that german quality and ethics? they certainly lost this customer for good.

No incident. Was driving and as I pulled into my driveway, heard bumping sound from car. Asked Mercedes what it was, they said loose baffle in gas tank. Sounds like manufacturing defect. Checked online and found many others with same problem. It is a costly repair just outside of warranty period.
