Electronic Steering Lock (ESL) fails and your key fob nor your keyless go button will function, rendering your car unable to start...! Usually it's the cheap toy motor that engages the moving tab that locks and unlocks the column and communicates to the ignition to start the car... You get only a message to "remove your key" and the dash lights will not come on nor can you start the vehicle... Mercedes is aware of this, as there are thousands of complaints on this ESL issue... Mercedes needs to issue a recall and do away with this faulty ESL module...!!!! Oh by the way, they charge $1500+++ to fix it...🤬🤬🤬
