2008 Hyundai Sonata Recalls

Rust 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.

Front Passenger Air Bag May Not Deploy When Needed

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 Headlight Assemblies May Not Conform to Federal Safety Standards

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.

2008 Hyundai Sonata Reviews

Been a great car so far. I get about 26-30 mpg. Best mpg was 34 on a 260 mile trip. Only problem so far has been the airbag red light came on at about 70,000 miles, and it was under a recall. I love how it handles.
