Purchased a 2011 Kia had an excellent experience! 18 months later my car stereo quits working. I call to see if it's included in my warranty. The parts department man tells me I must pay for diagnostics first...135 dollars then they're not sure if it can be fixed or replaced costing lots of money. Honestly referred my to Soundwerks in Scottsdale. Long story short it just needed reset. Thank you for honest kind friendly people at Mark Kia Scottsdale!!!!
