Like the others, my ML has an intermittent problem starting -- after turning the key in the ignition, the engine turns over but fails to engage and after a few seconds, shuts down. Call it a long (non)start. My good friend who is a mechanic told me that there is a fault in the ignition housing and electronics that is causing the system to not recognize the chip in the keys. Supposedly a major repair, requiring new keys (several hundred $), dismantling of the steering wheel, airbag, etc., and something that only a MB dealer can handle...
