Battery sucks...had battery issues before I reached 100K miles and Check engine light went on because of it. However, I wasn't going to pay 3K for replacment batteries and just ran the car without the extra HP the batteries would have given me. I still get 50 mph, and 200K miles later its still going strong. I have 310k miles on it now and runs great! Haven't really replaced anything on it except tires, oil, and struts. Everything on it is pretty much original!
The IMA Battery on the 2003 Civic Hybrid is/was a flawed product. My first battery failed at 42,000 miles ( at 7 years) and was replaced under warranty. The second battery has failed with less than 27,000 miles ( at 11 years) and the dealer says it will cost me $3,684 to replace it with a rebuilt battery with a 3 year, 36K warranty.
So far, Honda and I have spent more on batteries than I have on fuel for this car.
With a 3 year warranty on a $3,684 battery, I'm planning on $1,000 per year battery cost going forward.
I carefully documented my battery failures and appealed to American Honda for some cost sharing on the third battery.
They said sorry but you're on your own, nothing, period.
I was very surprised they dropped me so hard.
We bought two new Hondas in 2003, but they'll be our last.
Expensive mistake buying the Civic Hybrid!!!!
Bought new in 2003 and never had to replace a thing other that a couple headlights, main starting battery. Has 250K miles on it and finally the IMA has an issue, but still drives great without it! Someone rear ended me the other day, totaled his car, but only scratched my rear bumber.
I bought the car new in 2003 and it's been great. I see many complaints about gas mileage, but mine averages 49 MPG with snow tires on. This has been the most trouble free and economical car I've ever owned, and it's fun to drive.
Great gas mileage, reliablilty and low maintenance costs.
I've owned my 2003 Civic Hybrid for 2 years now and so far its been a great car with only a few minor problems.
The Good: Handles great Luxurious interior (compared to other non-luxury cars) Extremely quiet 45mpg
The bad: Transmission fluid needs changing every 2 years IMA battery will start to degrade after 7 years Seats are very stiff, its like sitting on a bench
Overall the car performs well as a daily driver, and if you aren't looking to set Nurburgring lap records you'll be satisfied with its performance. Even though it is less reliable than a standard civic the blue book value is lower, making it a better value when you factor in the better gas mileage.
