I bought my ml320 from dealer one month ago, had no problem before. Just last night it suddenly won’t start after 15mins waiting for my pizza. The symptom is it can’t start at first, clock on the car running really fast itself. Then the whole car had out of power, all the lights, indicators, door locks, all gone.
We thought it was battery flat, we tried jump up the car, and it did get us a successful 15 mins driving home. But then it won’t start again, power completely gone once I took off the key. However we tested the battery was actually full.
I really wish someone can help me on this
