We were driving and heard it missing and it started overheating, so we put more water in and decided to come home. So when we turned around it died 2x then the cylinders locked up and it wouldnt start. When we got home my husband found water in the intake and the oil. So we replaced the intake gasket and put it back together and it did it again, but then it made a loud noise and we found that the bar connection the piston to the crank shaft busted. The car only has 103,k miles on it.. Dont understand how its even possible. The only other person that owned it was an old guy. We only put 300miles on it when this happened.

While entering the interstate highway, car started losing power at 50mph. After getting car up to a safe speed, got the car home where it then stopped running and would not re-start. Mechanic checked and found that the head gasket failed at 130,000 miles. This car has always been well maintained. Nearly caused me to be rear-ended as I was on a70mph interstate highway! Also, your website keeps telling me I have an "invalid vin number!" This is the only one ever issued for this vehicle. What's with this?
