2009: “I was driving and the vehicle started overheating and smoking a lot. I pulled over and there was slushy fluid flowing from the car and I had to have it towed. I towed it to a nearby auto repair service professional for testing, and the test showed that the coolant was contaminated with transmission fluid and the transmission had coolant fluid in it. According to them, there was a malfunction of the coolant hose that allowed the coolant to mix with transmission fluid and as a result the car does not drive anymore. …”
