I have a 2004 Honda Civic sedan I took my car to scott robinson Honda in torrance California for a smog check without any mechanical problems my car passed the smog check without any problems. I left the facility one day later my car had the check engine light on. Went back to the dealer and they came up with a code that they said it needed a new catalytic converter. I became skeptical about this recommendation so I started looking through the owner's manual and read that an engine light on could be possibly a loose gas cap. So I decided to buy a new original fuel cap I went to the dealers parts department and purchased a new fuel pressure cap I noticed that the replacement cap did not look like the original but the part department person said that it would work just fine I then replaced the original fuel pressure cap. After a few days the check engine light turned off until a few days later the light came back on then I check the fuel pressure cap and it is loose I tighten it and in another day the check engine light is off. And it keeps doing this until now sometimes on sometimes off I also see that my fuel level gauge erratic it has been like this since I bought my car but I just did not think that this could be a problem I hope that something gets done about this thank you for your help.

I have 2004 Civic and I have a problem that is similar to one about the gas tank indicator. It started after my 30K service at the local Honda dealership. But, I did not complain to them, as I really do not trust these people. (they had quoted me for a full service, and then called me at work to say they had to replace the cabin filter, so added another $80... total to well over $500.) I knew if I went in with a problem they would take me for a ride again. Anyway the problem went away after I added stp fuel cleaner a couple of times into a full tank. Wall mart has these for about $2.50 for three small bottles, each work a single clean. I love my Honda. Nothing much wrong with the vehicle. It is just a good natured car, other than when trying to break gently at very low speed, as it has a tendency to jump. At low speeds, I now give my self space and I break with regular pressure. First, all cars will have some problems. Nothing mechanical can be perfect. So be aware of this when servicing a car. Secondly, the problem is mainly with dealers. Honda ought to crack down on these crooks by having set rules posted on doors of dealerships over pricing, what ought to be in a service, when the regular service is, etc. Even after the fuel affair was done with, I now watch how many miles I drive and fill it every 250 miles or so. That way it can never run out of gas. A few days ago I filled it up after 246 miles. It only needed 6.5 gallons to top it up! yes, that is over 39 mph on the highway mostly @ 65 mph. We as consumer should complain. We need Honda to be more aggressive with standards. If honest people sell cars for Honda, the image is that much better. Honda ought to watch out. I have driven cars from the competition that is better and better. They are a major engine away from catching up, but in the area of customer service they are passing Honda.

Needed to replace fuel door cable. This seems to be a common occurrence.

The fuel gauge goes crazy for lack of a better term. One minute you're driving and the gauge shows you have a half tank of fuel. A few miles later your fuel light comes on and implies your out of gas. Then when you fill-up, the car only needs a half tank of gas. As someone who does highway driving everyday, this can be unnerving. Someone else who had the problem said a dealer said to fix the gas gauge would be comparable to brain surgery. To go into fix it would probably cause some other problem.

Whenever im driving my 04 Pilot there is a loud and disturbing thumping sound coming from under the car..after speaking to Honda and taking the car in 3 times I was told this is a normal characteristic of the car and there is nothing anyone can do.after researching this issue I see that there are many owners withthe same problem but yet no recall is even in sight.the reason for the fuel sloashing noise is due to the long narrow shape of the inside gas tank..
