The 2002 Hyundai Sonata has 3 recalls, the most serious being side airbags that can deploy without a crash, raising the risk of injury to anyone seated next to the affected door.
The side impact airbag sensors are overly sensitive to sharp lateral jolts, such as a door being slammed hard, and can trigger deployment in situations that have nothing to do with a collision. On the braking side, installing the compact spare tire (T125/70D15) in any wheel position causes the anti-lock braking system to stop functioning entirely, with the ABS warning light illuminating to indicate the loss. Without ABS active, the wheels can lock up during a hard stop, reducing the driver's ability to steer around an obstacle. There is also a minor but real concern with the interior door handles: repeated use can wear through the chrome plating on the upper edge, leaving a cracked or separated edge sharp enough to cut a finger during normal use.
