Late last month, Hyundai recalled approximately 27,500 model-year 2009-12 Genesis sedans to address problems with the brake system's hydraulic electronic control unit. Now the automaker is expanding the recall to a total of 43,500 Genesis sedans.
The affected vehicles were built between April 30, 2008, and March 28, 2012, and may contain brake fluid that does not protect against the corrosion of the hydraulic electronic control unit, according to the National Highway Traffic Safety Administration. If corrosion occurs, reduced brake effectiveness could result, increasing the risk of a crash. The original recall covered cars built between April 1, 2008, and March 16, 2012.Hyundai will begin owner notification at the end of December, and dealers will replace the brake fluid for free. Owners may call Hyundai at 800-633-5151 or the National Highway Traffic Safety Administration at 888-327-4236 for more information.
