A couple of months back, the rear, right side door wouldn't open or close properly. I also noticed, before the door issue, that the car seemed sluggish going uphill, and it seemed like I was going through gas, a lot quicker. A few weeks ago, while parked, my car battery had died. I had no warning, and was 4 hours from home. Luckily it was able to be jump started. Now, when I try to start the car, it won't start. I have to put it in drive, then back in park, before it will start. Now when I start the car, my gas guage drops to below, what I had when I parked. Over the next few days, it will make its way to normal.
