When you purchase a vehicle with back up sensors apparently the wires for the censors hang suspended in the air between the bumper and the bumper cover. The wires on my car were chewed up and not working and when i took it in (still under the 5 year/100,000km warranty) they told me this is not covered by warranty, it is a VERY common issue, and they wanted to charge me for an HOUR of labour to find this "very common issue"
I called Kia Canada to voice my concerns about this not being covered by warranty and was totally blown off and told I could call back in later once I got my car back from the dealership. When I asked IF I did call back would I get any help with this issue the person I was talking to told me "probably not".
So far this company customer service BLOWS!!! Very unwilling to help you in any way, shape or form. NOT HAPPY!
