I continually receive a -??Low coolant -?? warning on my dash. While the truck was under warranty, the dealership replaced the coolant reservoir which contains the coolant level sensor. Now that my vehicle is no longer under warranty they refuse to fix the problem unless I pay for it. The dealership has refused to acknowledge that there is a problem even after replacing it three times.
