The car was parked for a week while visiting. (It has recently had its 30,000 mi.service) When I got in and started it, all the dashboard lights lit up including check engine. I tried reaching a Subaru near where I was visiting. No luck so I called my Subaru in VT. I was told I was safe to go as long as the Check Engine wasn't blinking. It wasn't so I drove home (I did note the steering wheel felt "tight".) When I went into the dealership upon my return, they did their computer diagnostic test. It was explained it could be as simple as not tightening the gas cap. The computer turned up something in the wheel. At first, he wanted to give me an appointment a week and a half out, but then found a car he could loan me that following Monday. I wanted to know why they needed it several days. He said it was to figure out the issue. When I asked if it was safe to drive, he said it was but there was a possibility of being on the highway and losing control/not being able to stop, but that was rare. I asked about the change in steering, as though the power steering was lost, and he explained they don't have that kind of system. I drove home slowly and went no where except Sunday when I drove a couple of miles to a farm stand close by. Upon returning into the driveway, I put it in reverse to park. It accelerated and when I tried braking, it wouldn't respond. It was a though everything was locked. The car jolted. Sped. Jolted. The side airbags deployed. My arm was banged up from the air
