WENT TO START CAR AND NOTHING. STEERING LOCKED AND DIFFICULT, DUE TO ALL WHEEL DRIVE TO TOW. THERE ARE MANY CASES DOCUMENTED ABOUT EIS/ESL FAILURES ON MERCEDES ENTHUSIAST FORUMS. THE PROBLEM IS PREVALENT ON THE INTERNET. THIS COULD BE VERY DANGEROUS ON A CROWDED HIGHWAY, IN A CRIME RIDDEN AREA OR JUST IN AN EMERGENCY. THE CAR WILL START ONE MINUTE AND WON'T ON THE NEXT START.
