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.

IN MY NEIGHBORHOOD APPROACHING A STOP SIGN ABOUT 20 YARDS AWAY. THE CAR ALL OF A SUDDEN ACCELERATED AT A HIGH RATE OF SPEED. I WAS GOING TOO FAST TO MAKE THE RIGHT TURN AND THE BRAKES DID NOT STOP THE CAR. I ENDED UP RUNNING THROUGH THE STOP SIGN UP AN INCLINE AND INTO THE WOODS HITTING MULTIPLE TREES BEFORE COMING TO A STOP. THIS CAUSED OVER $18,000 DAMAGE TO THE VEHICLE (NOT INCLUDING DAMAGE TO THE UNDER CARRIAGE). NOT ONLY WAS THIS PRETTY FRIGHTENING BUT WHAT COULD HAVE HAPPENED IF I WASN'T IN MY NEIGHBORHOOD WHEN THIS TOOK PLACE COULD HAVE KILLED SOMEBODY. IT REALLY SHOOK ME UP. THANK GOODNESS THERE WERE NO KIDS AT THE BUS STOP. I WAS ALSO SURPRISED THAT THE AIR BAGS DID NOT DEPLOY. THE INSURANCE COMPANY TOTALED THE CAR SO NO ONE REALLY SEEMS TOO CONCERNED ABOUT THE CAUSE OF THE UNINTENDED ACCELERATION THAT TOTALED MY CAR WHILE DRIVING IN MY OWN NEIGHBORHOOD! THIS SHOULD NOT HAVE HAPPENED. I HOPE SOMEONE WILL CARE ENOUGH TO TRY AND DETERMINE WHAT HAPPENED SO THIS DOESN'T HAPPEN TO SOMEONE ELSE.
