Two problems related to engine cooling system have been reported for the 2003 Honda Civic Hybrid. The most recently reported issues are listed below.
Air conditioning condenser is too low to the ground and fully exposed to stones, sand and road debris that kicks up from the highway. My condenser originally had black paint on it but it now is dented, leaks and looks sandblasted and is blocked full of road salt causing the defrost function and the air conditioning to fail and freon 134a to be exhausted into the atmosphere causing environmental damage because of this poor unprotected design. Recommend the manufacturer be compelled to make available some form of protective measure to prevent this premature failure of the windshield defrost function and air conditioning system.
In August of 2006 my vehicle overheated for the first time. I promptly took it in and they fixed an "air hose leak". After that my car overheated every few weeks without warning and after coolant had been found leaked into the engine a new thermostat was installed. It overheated a month later and the whole engine needed to be replaced.
