Two problems related to radiator have been reported for the 2013 Chevrolet Sonic. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2013 Chevrolet Sonic based on all problems reported for the 2013 Sonic.
I have found one new leak and one leak that has been there for at least a year. The new leak is the radiator. It is leaking at the top on the driver side right where the plastic and aluminum meet. The other leak is the plastic thermostat housing. Current miles: 69,500.
I have experienced four cooling system (radiator, water pump, engine block coolant intake, coolant expansion tank, engine/turbo coolant piping) related problems with this vehicle amounting to over three thousand dollars in repair costs. Four major repair expenses on the same system is questionable in my opinion, the two most major occurring within the same month. These all were noted during normal operation of the vehicle.
