Owners/service Manual problems of the 2006 Ford Escape Hybrid

I had gone va beach to washington d. C. And was on the way back when the vehicle had completely shutdown just before the hampton roads bridge tunnel in newport news. We were on the interstate during the entire trip and was lucky to be in the right lane. A aaa be tow truck pulled us off to the side. We tried to restart it but it shut off. Everything else was working fine. I went back the next day and the vehicle worked fine. I had it checked out by the dealer and they said there was nothing wrong with it. I just had the cooling pump replaced because of the recall. I looked at the manual and it stated that when the high voltage battery gets too hot that it will shut off. This could cause a serious accident. I believe that Ford should find a way to allow the vehicle to still operate on gas power when high voltage battery needs to cool down and to find a way to allow better ventilation so the battery does not get so hot since it is located in the trunk where people put their belongings.
