Hi Folks, My name is Dave Evans and I am in the UK. I provide assistance to our Club members (SLKOWNERSCLUB.CO.UK) - we have 2.7k members, I look at structure and corrosion issues on members vehicles)). Our members have had serious issues with the rear subframes on Mercedes SLK R171 models built between 2005 and 2008, there was no anti-corrosion treatment applied to the inside of the rear subframes during production, so they have rotted from the Inside - out so, when you can see corrosion on the outside of the subframe, it's too late! I have been working with over 60 members of our group alone, who have subframe corrosion issues. We have had 9 subframes collapse whilst being driven, fortunately, no serious injuries or deaths (most collapsed at low speed, fortunately) We are the only Club over here that has had any success is challenging MBUK with regard to rear subframe replacement. Up to now, we have succeeded in getting MB to replace 30 rear subframes FOC (Free Of Charge) and I am still working with over 30 members helping them with the subframe issues by providing Information Sheets, data, and further help sheets as their claims progress! We are fortunate over here in the UK that we have Ministry of Transport Tests (MOT's) annually which pick up a number of these subframe issues, we, as a Club have set up a help scheme where members can approach me for information on the procedures and process for making a claim and I provide a 'Rear Subframe Replacement Information Sheet' which covers the initial contact with MB, a draft email, description of the process, etc. for members to use for their claims. Should there be any further issues with the claim, I have further Information sheets that escalate the process. My cousin lives in the US and he has sent me some info on the issues with Mercedes over there, that sound very similar to our experiences over here. I wondered if Mercedes Owners Club in the US were having any success in challenging MB and having things like the rear subframe corrosion issues addressed FOC? If there is anything I can do to help, please don't hesitate to contact me? I am not sure how your site works, whether I need to include my email or not? I can be contacted through our Club site 'SLKOWNERSCLUB.CO.UK'. you will bare in mind that the information I have relates to the UK I think I have identified the US Customer Assistance details off the MB site and I suppose that you know your individual local Dealerships? that is where the UK information will have to be converted to US information! All the work I do regarding the corrosion issues, is done by me alone, so, as you will appreciate, I am currently working with our Club members so, I apologise in advance of any delays in my responses! I look forward to hearing from BenzWorld and it's members - Best Regards Dave Evans SLKOWNERSCLUB.CO.UK
