i use a power cut-off switch to keep a charged battery, but after more than 30 days away, the car will not start unless i push-start it..it turns over but sounds like it has no compression...after 4 or 5 attempts at cranking, it still just makes the same sound...i revert to push starting and have been able to start it that way....Detroit customer service has no answers for me and my dealership told me i should buy a different car..they said this car wasn't designed for my driving needs.(sitting at the airport for than a month at at time) imagine that!!! this has been going on since i purchased the car new in 2012..500 POP standard trans. any help?
