M157 cranks slow intermittent
ok we have a 2012 ML63, new to us a month or so ago... When we bought it you could hear the motor turn over slow like a weak battery then it fired right up.... after driving it for 10-15 minutes it started normally, motor turns over quick and fires up... figured battery was just weak sitting for sale...
Over the week noticed it sometimes starts slow and sometimes quick... this can happen after sitting overnight or sitting for an hr after being driven for an hr... very strange symptoms....
After a few weeks, we brought it to Sarasota MB and they installed a new battery....
Hasn't changed the symptoms....
In the service records i see a new starter a few years back and 2 batteries...
Any clues what's wrong ?
