We went on a 2-week vacation in January and came back to find the battery in our 2010 Honda Insight was dead. I completely charged the battery and inspected the car expecting to find that some light had been left on. I found that there was nothing left on that would drain the battery so completely. We took the car to the local Honda dealer asking them to check the charging system and battery to see if there was a problem. They checked the battery and told us everything was fine and the battery just needed to be charged. In passing conversation with a dealership salesperson, we were advised that we should have taken the battery out of the car and brought it into the house because the batteries in the new cars lose charge. We challenged the service department with this information and they admitted that this was a known problem with Civic, FIT and Insights and there was no solution because there was no more powerful battery that would fit these cars and there was nothing they could do.
We called Honda Customer Service. They said there was no problem with the car and that it was operating as expected and that sitting for 2 weeks was too long for the battery to maintain a charge. We were told that to maintain battery charge, we should be driving the car at highway speeds everyday for 30 minutes. When I asked the Honda Customer Service Representative where in the owner's manual it gave me that direction because the manual gives me a host of information to maintain my car, I was told it was on pages 63, 380 and 402 of the owner's manual. When I looked on those pages for the information, the manual advised me about warning lights and wheels and tires. There was nothing about maintaining the condition of my battery. I brought this to the attention of the Honda Customer Service Representative and asked them again to tell me how I would know that Honda expects the car owner to perform the needed battery maintenance of driving the car daily at highway speeds for 30 minutes.
Apparently, they do not need to communicate it because it is common sense. Then I asked how I could possibly know that my battery would die after 2 weeks of non-use and the response was that any battery will lose charge after an extended lack of use. I then pointed out the closest information that I could find on this topic was on page 383 of owner's manual that says if I put the car in storage and I quote the manual - "drive your vehicle every month for about 30 minutes. This will keep the IMA battery charged and in good condition". The manual does give the warning on the same page that if the vehicle is unused for over one month, the life of the battery is affected. I shared this information with the Honda Customer Service representative and they repeated that the car had sat too long and that was why the battery died.
The Honda Customer Service representative admitted that the information about driving the car 30 minutes everyday at highway speed is not documented. I asked to escalate this issue about the battery and charging system, but the Honda Customer Service representative said that they had answered my questions and replied to my concern and the situation would not be escalated as there was no reason to. I confirmed their comment and they agreed that I understood properly. I gave them my telephone number and volunteered that they can call me if they changed their mind. I was advised no one would call me.
In summary, Honda has been selling cars that they know fully well have an inadequate charging system and have not communicated with the purchasers how to ensure the batteries in Civics, FITs and Insights maintain adequate charge. Honda says it is reasonable that a battery in their cars lose their charge after only a few days from lack of use. They believe their position is reasonable. They have no interest in fixing the car and there is nothing further to discuss. In the meantime, the dealers are charging owners to test batteries, knowing fully well what likely the problem is. Sadly, Honda seems to becoming the replacement for old Ford and Chrysler's way of doing business.
