Around 4,000 miles my brand new van died on me going up a small incline round around a small curve. I lost all power and a head on vehicle almost hit me head on because I list all power, I lost power steering, I lost braking power and I and my dad almost died because I was veering off a cliff. I restarted the vehicle and was able to return the vehicle to the road. At around 5,000 miles my air bag light came on for a half of a day driving. I have had radiator fluid smell and leaking.
