2010 Ml350 electrical problem…..help

[Key9193]

Hello everyone, I am shaking my head at where to start. So for the past several months I have been back and forth with MB dealerships trying to get this problem fixed. The problem is as follows: the ESP light comes on,SRS, then the DRS light comes on, then ABS light comes on. (All inoperative). Then the automatic windshield wipers comes on. Then car can not shift into any gear but drive (a red message says drive to the workshop without shifting gears). The car slams into gear shifting while you are driving. Then when finally get it into a parking space you have to rip the key out to put it in park. Then I has to sit for hours to restart this horrible process all over. The wheel speed sensor are good. The car is well maintained. The problem is intermittent so diagnosing it has been a nightmare. Can anyone tell me what’s wrong? The diagnostic tool says communication error.

Check your batteries, you should read <12.6 with the car asleep and <14.8 with the engine running, anything less than 12.4v and you can expect sporadic random and anomalous faults to appear.
