Electrical problem?? E550 2011 covertible


My car odometer just jumped up from 122,000 to 199,000 and my car doesn't start anymore. I already changed the starter in april and they checked the battery, no problems. I'm taking it to Mercedes tomorrow, but maybe in the meantime you guys know what could be causing this issue? Seats don't work no power at all, but it does click when you turn the key and the rear lights work...idk what it could be..sucks
Thanks
