Electrical problem
2006 Mercedes Benz ML350 6 cyl All Wheel Drive 30,000 miles

My car has starting problems - nothing happens when I turn the key. Seems to have plenty of battery power (lights etc.) And the issue happens with both keys. I think it's either an electrical issue or a computer chip related issue. The dealership has replaced and updated the SAM module and also the main car computer but still have the problem. I would like to just disconnect the battery and let everthing reset but I cannot find the battery. 2 questions - where is the battery and has anyone experieinced similar problems?

i faced similar issue, my car is mercedes ml350, it was working fine, and doesnt have any problem with no accidents record, someday the car didnt want to start, it was not battery issue because all the lights were working fine and the radio with full power sound, I checked all the lights outside the car also working fine, then I realized that the issue must be regarding one of these :

1. Electrical circuit (connected to the engine)

2. Fuse issue connected from the chip to the engine

3. Some problem with the chip

one thing more, when I searched online I found many people complain similar problems like engine doesnt want to start, or electrical circuit issue, and all these only with the ml, this car is great but it has some issues about the electrical and the worst thing I discovered about this car is the battery location (under the front passenger seat!), This is the worst place, because the seats doesnt move unless the car was on, now the car doesnt want to start, how I can move the seat forward to reach to the battery to reset the whole thing, I tried to put it to the ignition position, but the seats dont move, why it's not in the back like other mercedes cars?. I can not move the seat at all.
