Throttle body wire harness went bad and was on interstate and could not do speed limit and nearly got demolished by a semi tractor trailer. After a horrible expense I now find out the wiring harness for the car is bad as well. Well done Mercedes Benz you have endangered my family's lives with your sub standard business practice. You should be forced to recall and repair all safety issues.
