Dec 2- filled car with gas, check engine light illuminated and then three more errors displayed on the dash. See list below. Errors displayed on dash-€¦ 1-INOPERATIVE -- SEE OPERATOR-€™S MANUAL (Shows ABS and skid icons) 2-COLLISION PREVENTION ASSIST PLUS INOPERATIVE 3-ABS CURRENTLY UNAVAILABLE -€" SEE OWNER-€™S MANUAL 4-CHECK ENGINE LIGHT ON Later that same day, Dec 2, we started the car but could not get it into Reverse. We shut the car off, started it again, and were able to shift into reverse and proceed. Dec 3rd- we attempted to remove and reapply the gas cap to see if engine light would go off and error messages would resolve. It did not. We did not drive the car that day. Dec 4 and Dec 5th- all above error warnings display all day. Dec 6th- We scheduled a service appt at Mercedes in Sarasota, FL for the 1st avail appt Dec 10th. We were told in writing the car could be driven until the appt and no additional issues should arise. Dec 7th- new error code appears-€¦ 5-REVERSING NOT POSSIBLE - SERVICE REQUIRED. This is when the car put our lives at risk. While driving, the car shifted itself into Nuetral. We were unable to get the car into gear as it continued to roll. Having no control of acceleration, we guided the car to the right to allow traffic to pass. We put the car in park, shut down the vehicle, wait 15 minutes, and restart. We were then able to drive forward, but WHILE MOVING, -€œREVERSING NOT POSSIBLE-€ reappeared, the car shifted itself into neutral again. We were unable to shift to DRIVE. We shut the car car down again, started it, shifted to drive, but it went into DRIVE 2 only. We drove in 2nd gear until we were safe off the road and home. We towed the car (12/7 evening) to Mercedes in Sarasota FL. Dec 8th: Service dept finds the two front wheel speed sensors failed and caused a chain reaction sequence of events. They referred to the problem as -€˜minor-€™. This is a serious design flaw. We are lucky not to have been hurt or killed
