Granted, somebody somewhere should have noticed a partially opened radiator cap, however I did not have issues with the car overheating, signs such as steam or even the temperature gauge indicating the car was running hot. When I purchased the vehicle one year ago, a coolant flush had been completed. Last week, when the car shut down, I drove the vehicle 15 miles, highway speed. I thought I smelled coolant, although the temperature gauge indicated the vehicle was running at normal temperature, I took the first exit to go a service station and that is when the vehicle shut down. At that time, there was no steam or any indication as to what I would assume the vehicle had overheated. The first place the vehicle had been towed to, told me that I might have blown a plug and once he got into it, is when he discovered coolant in the cylinder, which would be covered under the Dodge warranty and the vehicle had to be towed to a Dodge dealership. The dealership is now saying coolant is in all 4 cylinders, asking for maintenance records (which I have)...I am not a mechanic...but I do know how to take care of my vehicles.
