I own a 2011 Kia Sportage with 20000km. I hadn't driven it for 2 weeks and when I went out after that time, there wasn't a single spark left in the battery. Not even the keyless entry would work. When I purchased the vehicle, I had the Diamond Kote Rust Inhibitor installed. After I had it jump started I took it to my Kia Dealership and they checked out the vehicle but found no reason why the battery failed from 14 days without being used. Do you have any suggestions or have heard of other Sportage users with a similar problem?
