general problems of the 2007 Honda Pilot

I was driving on a masspike (I-90) at 60 mph around 5 pm westbound. All of a sudden, without any warning, everything just went out in the car, the engine just died on me, all the lights on the dashboard, navigation, etc. Neither the accelerator nor the brake worked on me. I was lucky enough to pull the car over to the far right lane. But I couldn't turn the emergency signal on because there was no power. In addition, windows didn't operate either so I couldn't even let other drivers on the road that I was stopped in the middle of the highway. I called aaa and the state trooper. While I was waiting for them to come out, about 10 minutes later, the power came back on by itself. So I finally turned the key to the off position and tried starting the car again. And it started and I dropped off the car at the service department at the dealer. I was very lucky that I didn't get into an accident and also lucky my 7-month-old daughter was not in the car with me. This is a serious safety issue to me and therefore, I filed a complaint to Honda. After 4 days, case manager finally called me back telling me they will fix the car. The mechanic thinks it's a battery cable problem. I bought that car brand new and drove it for about 18 months with about 40,000 miles on it now. According to the case manager, because the car is out of warranty, there is nothing they can do other than fixing the car "out of courtesy. " I don't want to be in that car, not especially with my little girl. They can't even guarantee me that this won't happen again when they "fix the problem" they think is the cause.
