Mercedes-Benz GLC SUV GLC 300 4Matic AMG Line 5dr 9G-Tronic Owner Review

Two weeks after delivery I started getting messages saying 12v battery was critical or discharged. Back to Mercedes and their Star system found no faults. two weeks later messages saying critical battery. Back to Mercedes and same old story 'No Faults' This continued having and now about to return to Mercedes for the 4th time in 7 months.The car can not be parked more than 2 days without 12v battery discharging. Hence can not long term park at airport, etc. Not a useable car. From the Internet I see that many owners have similar issues but yet Mercedes do nothing to cure the problem. I'm afraid never again will I buy a Mercedes car.
