2006 Chrysler Sebring 2.7L trouble starting, acts like it might stall out when stopped, keeps running out of coolant, sometimes smoke when you first start out of exhaust, help!

So my 2006 Chrysler Sebring 2.7 L
engine is having some trouble. It's
getting older but I need it for right
now and it's having some issues.
Today I went to crank it for the first
time in about a day and it wouldn't
start. All the lights worked but it
made a single click and wouldn't go.
I was sitting there trying to assess
the click and trying to crank while
after several attempts it just started
up but it struggled and there was a
lot of light smoke out of the exhaust.
The coolant has been running out
almost every day and a half. I've
replaced the thermostat housing 3
times, it currently has a factory made
with a rebate on it, it's been almost a
year since I last replaced but it has
no leaks in it the coolant is just gone
after driving around. Besides that the
emergency brake light comes on and
off now and the horn stopped
working but you can hear it muffle
every now and then as it acts like
there is some electrical issue. Can
anyone tell me what is causing it to
have trouble starting or when at a
light it sometimes acts like it wants
to stall out til you give it gas? It's
automatic as well. I also need to
know why the coolant is running out
or why I would keep having this issue
with the thermostat housing? Please
help.
