Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct.

If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.

2008 Hyundai Sonata RecallsRust Concern with Rear Suspension
The rear suspension is the attaching point for the control arms and other rear suspension components. Road salt and water can accumulate in and around the rear crossmember causing it to rust. Excessive rust could cause one or both rear control arms to separate from the crossmember resulting in a sudden change in vehicle handling, increasing the risk of a crash. Dealers will inspect the rear crossmember and repair or replace it as necessary to correct this concern.
The front passenger seat sensor, to detect a child seat or adult in the seat, may recognize a small adult as a child seat. If this happens and the front passenger air bag is deactivated, the risk of injury in a crash may be increased. Dealers will verify the Occupant Classification System (OCS) is not working properly. After verification, dealers will remove the front passenger seat cushion and send it to a repair facility. The recall began May 26, 2008. The Hyundai recall number is 083.
Replacement headlamp assemblies may not conform to the Federal Motor Vehicle Safety Standard because they may not have been aligned properly and fail to conform to the photometric requirements. Improper aiming of the headlight may result in poor visibility and possibly result in a crash. Dealers were notified and returned their supply of headlights to Hyundai. The Hyundai recall number is 080.
