Honda 2003 Accord is equipped with a "design defect" of costly and potentially harmful, from a safety standpoint, defect. The lower "grill" on the front bumper is designed in such a way that any road debris smaller than a 16" x 8" concrete block can enter and damage a fully-exposed and unprotected ac condenser. It is clearly unprotected from the harsh outside elements. The ac is an integral part of the safety of this automobile in that to clear the windshield from any moisture on the inner surface, the ac must be acting in proper fashion. If a car's inside glasses "fog-up" with moisture , the only solution is to turn on the moisture wringing ac unit, regardless of the temp of the air, the dehumidifier effect of the ac conditioned air is an absolute necessity. The current design of the grill/condenser leaves it vulnerable to be easily damaged by a bit of gravel as small as a bb pellet. There is not any screen or deflector in place forward of the condenser to prohibit any errant road missiles from damaging the condenser thereby creating the safety hazard of a fogged windshield and more, a simple screen or deflector could and should be installed to protect the safety feature of this car.
2003 Honda Accord ex sedan with 4 cylinder. Car has developed high idle 1800 rpm when starting a cold engine(started after 3500-4000 miles). Car will accelerate (actually jumps) to 20 mph with foot off the accelerator(it will spin the tires on wet pavement and winter is around the corner and can only imagine what driving will be like). Takes over +5 minutes before it reduces to a normal idle (approximately 2 miles worth of driving). This is a really dangerous situation. Also experiencing the rotten egg smell entering into the drivers compartment. The air conditioner (a/c) has a serious vibration when coming on that has had several passengers ask me what the noise and vibration were. It's a shame since I have been to the dealer 4 times for these problems and came away with them making me feel guilty and that I'm the only one with these problem. I feel this is an extremely dangerous situation and have told the dealer so. I guess I'm glad that sites like this exist. . . Thanks.
