Have had this car for two years and it was great. Put approx 2,000 miles on it in two years. Bought it used for 7 thousand. Then big mistake, left key in car 2 days b4 I discovered that I had. Charge was gone and tried to re charge it. No luck. Had it towed to Mercedes and was told it needed a new battery for $27,000. Crazy, car only sold in 2014 for $30,000 new. I had it towed to someone in Arcadia,California and they told me yes, it needed a new battery. Now I just need to figure out how to deal with this, not much interest in electric car needing battery. Read in this forum about battery warranty but Mercedes tells me no. Even talked with Mercedes USA. Would anyone out there have any suggestions on what to do with car? I'm in Southern California. Any suggestions?
