The automatic stability control component of the suspension system in approximately 1,970 2006 Hyundai models is the focus of a recall that began on July 29, 2005, according to the National Highway Traffic Safety Administration. The NHTSA campaign ID number is 05V316000
Problems with rear suspension are more likely to occur on models equipped with 3.3-liter engines and electronic stability control. Sonatas and Azerras produced from May 5, 2005, to June 10, 2005, are among the affected vehicles. Strut problems are not as common on the Hyundai I4.
Electronic stability control identifies over-steering and activates the front outside brake. In the affected models, ESC may be activated unnecessarily. Testing revealed that the hydraulic electronic control unit required reprogramming in accordance with the National Traffic and Motor Vehicle Safety Act. Owners of the affected vehicles may also experience a thunking or klunking sound.
Hyundai dealerships may recommend installation of a rubber bushing on top of left and right rear strut mounts or replacement of struts. This particular job requires approximately 30 minutes of labor.
