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.
