My parents have a 2007 Honda Odyssey minivan with right around 14,000 miles on it. It doesn't get driven a whole lot. The car is on its 3rd battery. The dealership tells them that the batteries are going bad because they don't drive the car much.
The last issue happened 2 weeks ago. My mom said the car had sat for a week and she went out to run errands and it started with no problem. Then the next day she had to drive it again and it wouldn't start. It was towed to the dealership and they gave her the battery went bad due to lack of use story.
They're taking it back today because it wouldn't start again last week and needed to be jumped. Now the dealership told them it may be a sensor or something that is causing the battery to drain.
Any ideas from you experts?
