Two batteries died completely and I had to call AAA. First time they told me it appeared to be a just a bad battery. I purchased a new battery. Called AAA again. They said it appeared to be a bad alternator. I exchanged the dead battery for a new one, took it to my mechanic and he put in a new alternator. After not using for two days it died again. I purchased a portable battery jumper and had to use it twice. I finally purchased another battery, better, more costly and went directly to a new mechanic who is a certified "Master Technician". He worked on my car for two days and could not locate the exact reason why my battery keeps dying.

I went to "Rick Case Honda". I was assured they would find the problem. I left it there all day. I had to call them to find out what was going on. They said their "Master Technician" couldn't pin point the problem. I would have to pay for one "possible fix", and if it happened again, they would try something else. The Assistant Service manager suggested I "junk" the car, and he wanted to hook me up with a Salesman. I said no and told him I would pick up my car the next day. I know it's an old car, but I'm not financially ready to purchase another vehicle. What I want to know is, why can't Honda repair their own vehicles.

They're always bragging how great they are because they are trained only on Honda vehicles. Now I'm stuck with a piece of garbage that I kept in good condition though out the years, and Case Honda can't even give me an estimate to repair it because they don't know what the hell they're doing...

I really thought I was the only one having a problem with their batter dying almost daily. About 4 years into ownership of my Accord I was noticing the radio would turn on without the car being turned on. I took it to the dealer when my car was still under the ext warranty. They said they fixed it but when I went to my car after getting my keys the radio was playing and the keys were in my hand. I was really angry because, if they are certified and want us to bring our vehicles to them, they should know how to fix the problem. I had to eventually purchase a jump box, because it got so bad that my battery would die overnight. Worst case my battery had died over an 8hr period..I was at work!!! I finally had a friend take my car to his mechanic and they disconnected the FACTORY RADIO. My battery hasn't died since. I'm still angry to have spent over $20k on a vehicle, and don't have a radio!!

I am the person who reported the previous problem with the battery repeatedly losing its charge. I did not try removing any fuses as one person recommended, but I found that if I did not turn on the original Honda factory-installed security system, the cars battery remain charged no matter how cold the outside temperature was, or how long the car was not used for. I will call the Honda District trouble-shooter to set up an appointment to see if they can track the problem down - I believe the security system has a wiring fault or short that causes the battery to drain out overnight. Well get back to you with Honda's response.

My problem with my 03 Accord Coupe EX sounds like the others. The car battery dies repeatedly. It doesn't die as much if I either drive more than 100 miles a day which I usually do, or don't let it sit for over a day and a half without starting. Something is draining out the battery. When it gets colder (below 40 degF outside) the problem shows up more often. Currently just start the car with a portable power-pack (best $40 I ever spent just like the other guy said). Am going to try to remove the radio fuse like one guy said and will let you know what happens. I might try removing other fuses to see which circuit might be draining out the battery. Will also call Honda to see if they have any updates -I would expect them to at least acknowledge there is a problem.

Update from Apr 10, 2010: Eventually I solved the problem in two stages: 1. I disconnected the after-market security system that was added to the original security system before I had purchased the car second-hand; 2. I re-wired my after-market sound system amplifier which was wired directly to the batter so that when ever the car was turned off the amplifier (hidden in the trunk) was still drawing amps from the batter. The problem is fixed so I can only say that the two items drawing on the battery when the car was shut down were after-market products (security system and sound system.)

I have a 2003 Honda Accord EX V6 2 Door. I have had the car for about a year. Last Christmas I took the car in because the headlights would dim and brighten when you drove the car. The volts would range from 12.5-14.5. They said nothing is wrong with the battery or alternator. This is a normal Honda thing they said. I picked up the car 3 days later when I got back into town. It was about 20 above outside and it was dead as a door nail. The Honda Dealer said to install a better battery, so I did. I bought a gel type battery that cost around $130.00. At this time I drove the car everyday. For the last few months I onlt drive the car every 3-6 days. (I drive my crown vic to keep the miles down on this stupid Honda!) Every time i get in the car the battery is dead enough that the car only clicks. I have jumped it with a power pack more than 20 times. (best 40$ ever spent) I have put a tester on the battery with the car off (12.35V) and running (14.5V). With the battery disconnected it was 12.40V. So what is a guy to do. This is not a reliable Honda. I am thinking about trading it in for another Ford! Now I know why the car dealer was so willing to get rid of it!!!!!

Since late last year, my electrical system has failed on at least 6 occasions. Four new batteries in the past year. I have had to carry around a portable battery charger and when I charge the battery it will start. It doesn't matter whether it is cold or not. Once we had driven it with friends to a parking lot near a beach. Over an hour on the road. Everything was off including the radio. When I got back in to start it, it was dead. No crank in the battery. Hooked it up and it immediately started. Honda has a problem on its hands. It sounds like the same complaint others are having. I left it at the dealer for two weeks and they couldn't get it to repeat the problem or find a problem. It has been in the dealer for the same problem three times. I think it is a bad internal computer chip that is not being located by the service department computer. My business partner has the same year, make and model with 25k on the car and it has happened to her twice and the battery replaced twice. I wonder if similar Acura models are doing the same.

We bought our honda from a certified honda dealer and I must add that we traded in our 2003 F-150 lariat that never gave us a single problem, anyway three days after we got the car it stopped running while my wife was driving. The car went to the dealer and changed the batt. and the alternator but couldn't tell us what the problem was. Three weeks after that the same thing happened and still no fix from the dealer. They say the car is fine. Well it has happened 5 times to be exact and still no fix. The worst part is that the service sucks from three different dealers.

Accord has died eight times since purchase. Dealership cannot determine the problem and Honda Canada unable to provide any assistance or relief. The period between breakdowns vary from three days to three months. We have asked for a new vehicle. This was not entertained. Bought two Hondas as most believe to be relatively maintenance free but have hard more than my share of problems with both the 2003 Accord and 2004 Civic. Dealership willing to investigate but to date no remedy has been provided.
