2004 Hyundai XG350 Reviews

I like this car. The only issue I have with it is that it makes a "rattle / vibration" sound when first started, especially when backing up in cold weather. This goes away after a few minutes of driving. I've seen other drivers on online forums with the same problem. So far no one has an answer for what this is - including Hyundai. Otherwise it's a great car for the price.

My dashboard top facing the front windshiled strted to spilit on driver side because of the Sun. I can still push it down and it stays for a day or two, Is there cheaper way to fix it?

I bought the 2005 XG350 off the show room floor and I haven't put a dime in it except for oil changes. The only thing is the motor sounds like a diesel.
