We bought the Honda Civic in Feb 2012. Drove about 1000 miles. One day I feel little hesitation in third gear. I open the hood to just check, and found the water all over the engine compartment and hood liner was wet and soggy. I was surprize and worryed thought cooling system busted or loose hose clamp. But after tharough checkup found that rain water seep thru between front hood lip and grill. I told my wife not to drive the car, it's not safe, because water can damage the electric component and may cause fire. So I dry the engine area as much as I could. Setup the appointment with Honda dealer. First of all the service suppervisor did not belive, and then she check couple of other cars same model and year,and found that all the cars are the same design nothing missing. She suggest to call the Honda manufacture. I asked for the work order, she said there is no problem so no work order need to fillup. I talk to sale person about all this; he said the same. I was very disappointed. I ask for the service manager; and show him the car and problem; he said the same to call manufacture. But atleast he agreed to write the work order. That consumer complaint this, and we could not find any problem. As per consumer the rain water get in to engine compartment and wet the hood liner and other electric equipment and plugs.
