Hi all, I have just bought a 2017 E350e with 27000 on the clock and when fully charged it is only reading 10 miles range and not even giving that, I read it should give 21 mile range but I don't expect to get that obviously but as its getting less than 50 percent and its still within warranty do I have a case to bring this up with Mercedes as they warranty the battery pack for 6 years or 60000 miles. Anyone tried this and if so what was the response from Mercedes.
