2012 Kia Optima Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2012 Kia Optima

My Sirius Radio goes out with a sharp right, back on with a sharp turn left, or does not acquire a signal at all. what is causing this? Paying for membership that i am having problems using. Radio works.

I just had my 45k service done and the price without the spark plug change was $160 which is close the estimate posted here. The service advisor has quoted me a price of $475 plus tax to replace the spark plugs - saying it needs other things in the "tune up" package that are not listed ...

I am not sure if I should replace the radio or the amp or a fuse. The radio lights up and looks as if it functions properly however, no sound at all. Advice?
