Our vehicle dies while driving down the highway, twice now in less than 30 days. I drivetrain and low-power warning came on, but the car died and wouldn't start. The obvious risk is that we were driving on the highway and barely avoided being in an accident as I tried to steer us off the road. The second time we were at a park. In both instnances, the temperature was over 100 degrees and my 3 and 5 year old both got sick from overheating. We were stranded in the middle of nowhere. The dealership said "it probably just overheated, we couldn't find anything" but assure us it won't happen again. It did less than 30 days later.
