OUR FAMILY OWNS 5 VEHICLES OF THE SAME TYPE (MERCEDES GL). ALL HAD OR CONTINUE TO HAVE A PROBLEM WITH THE RPM SENSOR AFTER ABOUT 30.000 MILES. THIS PROBLEM CAUSES DANGEROUS SITUATIONS WHILE DRIVING BECAUSE THE CAR JUST SHUTS DOWN AND DOES NOT ACCELERATE ANYMORE. WE INFORMED THE CHAIRMAN OF MERCEDES BENZ, DR. DIETER ZETSCHE, ABOUT THE ONGOING PROBLEM. THE BOARD'S RESPONSE WAS THAT THESE ARE ALL ISOLATED INCIDENTS ALTHOUGH ALL OF OUR 5 VEHICLES CONTINUE TO HAVE THE SAME PROBLEM. MERCEDES CLAIMS THAT THEY ARE UNAWARE THAT THIS PROBLEM HAPPENS WITH OTHER GLS AS WELL. HOWEVER, NOT ONLY DO OUR 5 GLS SHOW THE SAME PROBLEM BUT WE FOUND OUT THAT OTHER GLS HAVE THIS PROBLEM AS WELL. TWO MERCEDES DEALERSHIPS WE USE IN THE UNITED STATES ARE AWARE OF THIS PROBLEM AND THAT'S WHY THEY GIVE SMALL DISCOUNTS ON THE SENSOR PART AFTER THE WARRANTY HAS EXPIRED. BUT WE FEEL, BECAUSE OF THE SECURITY RISK, THAT THIS PROBLEM DEFINITELY WARRANTS A RECALL.

The EIS module we have found has an issue with the part from Japan that does not have enough Sauder on a part of it, so when the temp drops below 50 degrees or less the ignition starts but all the safety features go off and the computer shuts down the vehicle. Reason is the metal contracts in cold weather causing the connections to not fully meet. We have figured this out after many times of replacing the main battery, aux battery thinking this is the issue. After much research on the web and MB forums this seems to be an issue especially in the colder climates with some of the older models. Some others have had have their autos stop in the middle of driving them in cold weather. Not sure why this has not been reported. We are having the issue now with a 2010 MB GL 450 we just purchased in November and every time it gets cold, the auto goes haywire when the temp drops. Warm weather zero issues. Wanted to relay since we do not see a recall and we are working out the bug on this on our own time and money.

I received an Stop Drive Order form Mercedes Benz USA more that a week ago and I stopped driving my vehicle. I contacted the closest authorized MB dealer Union, NJ and they have not provided a loaner car and have not yet fixed the issue. They say they have so many calls and cannot do anything for me despite the fact I waited so long. I need this car on a daily basis and cannot do my work without this car. I have been calling them over and over and they disconnect the phone. This has been really frustrating. They are also saying that they are not willing to pay for any cab fee, Uber or any rental car fee. I need my car urgently and am really scared to drive this car after they sent me the STOP DRIVE Order
