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. This is a very rare situation to see in a car with this few miles, five years old and maintained well. I then took the car to the dealership, which confirmed that the issue. However, the dealership began to blame me for it by saying that I put water in the coolant which caused the coolant reservoir to freeze and the hose to malfunction. I told them that I have records of consistently taking it to a GM dealer for maintenance, repairs, and anything thus why would I now try to put water in the coolant. I did not put anything in the hood area or receive a coolant flush because the car just turned 5 years old a few months ago. The dealership I took it to is providing biased information because I did not purchase the car with them or use that location for previous repairs. They acknowledge that this is an unusual issue. I called GM and they worked with the customer service manager at that same dealership to try to resolve the issue and the dealership and GM is not trying to do anything. The vehicle has been maintained by GM dealers for the entire life of the car, I am the only owner, no accidents and I cannot reach a resolve with them. There is clearly an issue with the manufacturing of the car and the equipment has a defect to allow coolant to mix with transmission fluid, but no one is trying to help because it is expensive to repair the issue.
