Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

2004 Hyundai XG350 Reviews
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.
Worst car I ever owned. The dealer I purchased it from is disgusting. Will fight you over every warrenty issue imaginable. Lester Glenn AVOID them at all costs
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.
