This is my first and last KIA. I purchased this vehicle in October 2008, and it is nothing but a maintenance nightmare. As soon as we hit 35,000 km, we have repeatedly been in the shop for one thing after another. Additionally, the cost of regular maintenance (e.g. oil changes, etc..) far exceeds any other dealer. I have been unable to utilize the services of businesses like Mr. Lube, because they have been unable to access the filters for this particular vehicle, so as a consumer, there is no choice but to go to the dealer.
As for the hours the service Dept is open, if you work for a living, expect to have to take time off work to get anything done. The Service Dept at the dealership I am forced to go to almost never answers their telephone. Instead, it goes to an answering machine with a message that tells you they will return your call within the hour. I have yet to have them return my call on the same day, or at all. Very unhappy with the service aspect of KIA Canada, and for this reason would never purchase or recommend a KIA.
My last new car was a Honda, and in hindsight, I should have bought another one, because the KIA has cost way more in service work than a Honda ever will.
