While driving it I received the smell of coolant and I stopped the car to check and I noticed the liquid leaking through a pipe in the entrance of the head block where the engine thermostat is. I took it to a mechanic and discovered tiny needle point size holes in one of the tubes. These holes were made from inside out of the part. This is the first time one of the cars I have had does something like this. I had to buy the part that cost me $250. 00. I think it was due to poor manufacturing materials.
