Instrument Cluster malfunction. Battery drained and replaced. 2.5 weeks later, the new battery drained. After the vehicle was jumpstarted, the instrument cluster remained on with SOS inoperable showing on the panel. The instrument cluster will not turn off, even after the vehicle has been turned off. So it continues to drain the battery. Mercedes has diagnosed the vehicle with a bad instrument cluster and says that it needs to be replaced. There were no warning signs before the malfunction. I drove it and parked it. Then two days later the battery was dead. 10.19.21 - took vehicle to Mercedes for a regular schedule B service 10.21.21 - vehicle battery was dead after trying to crank it. 10.22.21 - Mercedes sent tow truck to bring it back to them. The battery was replaced on 10.25.21 and I picked up the vehicle. 11.10.21 - Vehicle NEW battery was dead again. Mercedes sent tow truck. The tow truck driver jumpstarted the vehicle and couldn't get the vehicle into neutral. Then the SOS inoperable message appeared. Vehicle was towed to Mercedes and diagnosed the next day (11.11.21) with a bad instrument cluster. Apparently there are no new instrument clusters available in the world, according to Mercedes, they are on backorder. And I cannot get a loaner vehicle. So they'd like for me to be without a vehicle for the foreseeable future.
