One bad apple gives all sports cars a bad reputation?
I canât imagine I said that what you described was normal, but I canât speak for anybody else
Hereâs a good link on parasitic drains.
âOthers, probably high-end cars with lots of high-end gadgets, will draw moreâ
Youâre entitled to your opinions
But there are several newer high end cars in my area
The owners do not use trickle chargers
And some of the vehicles sit for extended periods
And they start up fine
I understand the scenario youâre describing, but those vehicles that do not start after sitting for several days are experiencing problems. It is not acceptable or normal.
Here is a update on my 2010 Aveo with battery going dead, mechanic told me it was something faulty in my radio draining my battery, so i found a replacement Radio ($75) on E bay , I switched it out in 5 mins and took it back to mechanic to have him test for draw, no more draw , it was the radio car is fixed and good to go ') 
Good for you for getting the problem resolved OP. A phantom current drain is like any other kind of leak, just have to eliminate the possible suspects one by one until you eventually find it.
I agree itâs not acceptable or normal. If youâll scroll up and review what I said above, I doubt youâll find the words acceptable or normal.
thanks george
That seems to contradict what you were gettng at earlier, in my opinion
But letâs just forget it 
Fair enough.
Are you enjoying your âbirthdayâ cake . . . ?!
Coconut frosting ,my favorite 
now my engine light came on, code saying high voltage at thermostat, its not over heating and I have heat so i dont think i will worry about it
My chevy aveo has the same problem with the battery drain. When I pull the 10 amp odb2 fuse. the problem goes away. This fuse also controls the onstar, which I have heard can can create a battery drain when it goes bad.
Thief canât steal a car if it wonât start! 
I had the same problem and it was my OnStar searching for a signal ( I donât subscribe). Removed the fuse and it was fine.
Get another battery. My 2009 Aveo original battery would die or just be randomly dead after three +/- years of ownership. The second new battery would also die or just completely be dead randomly the following year. Both checked good at the local auto store, holding a full charge / load tested.
The third new Battery has solved that problem.
This old discussion started with suspicions of an overnight parasitic draw. I think these days you can find a voltmeter/ammeter system that will log data. That would certainly help finding this vague problem.
