I'm sure it's hard to diagnose problems with these high-tech cars. I have owned 4 Kias since 2004, because I love them & have faith in their reliability. However, my newest Kia is still under warranty and hundreds of miles into our first "road trip" vacation since 2006, Kia Connects alerted us to a problem. "The battery is failing to charge," then the check engine light came on, and our AC isn't working efficiently. After spending all afternoon in a Kia dealership in another state, they told us there was a loose wire & sent us happily on our way. Twenty miles down the road the check engine light came on again & the AC periodically blows warm air (when it's 95 degrees outside!) Since I didn't hear from Kia Connects again, I decided I couldn't ruin our first trip in years by worrying. Instead, we enjoyed our vacation and made an appointment with Steven Toyota/Kia as soon as we returned. After checking the car out & getting the check engine light to go off, they said the AC was working as it should. Having faith in them, we drove back home (over an hour one way). The next day we woke up to a dead battery, the check engine light was back on, & the AC is still not reliable, but better. We're headed back to the dealership again on Friday... What in the world?
