New To Chrysler Cars

I recently got my hands on a 94,500mi 2008 Chrysler Sebring Touring Convertible. I’ve only ever worked on my 2000 Honda Accord, so it’s quite a different experience than what Im used to.

I found some invoices from work done to the car from anywhere between 10,000 to 20,000 miles ago. It has had a new oil sending unit/sensor at 80,000 miles. The AC has been redone.

At 73,413 miles, it had an alignment, rotation, 4 new quick struts, 4 new brake rotors, new brake pads, and a new battery. The guy who had it last also installed a touchscreen radio, new speakers (the rear speakers dont work still) and a backup camera (that isn’t connected to the radio)

The battery has currently taken a dump so I know I need a new one. And besides the convertible top not working, there aren’t any issues with it that Im aware of.

With the 2.7L V6, what kind of problems would one normally run into and how should you fix them?
