I have a 2010 ml350 with 24000 miles on it that just had a defective EIS switch replaced. I spoke to Mercedes and they admit that this is a common problem but will not do anything about it at this point in time. A $1400.00 repair is not acceptable on a 24000 mile vehicle . At this time please post and let me know if you have had a problem and if we get enough response we can take it to the next level with mercedes
