Hyundai expands Genesis recall over brake fluid

Hyundai is expanding a U.S. recall of 2009-'12 Hyundai Genesis sedans to replace the brake fluid, according to the National Highway Traffic Safety Administration, reported

The expanded recall covers an additional 16,000 cars to bring the total number of Genesis models affected to 43,500.

The cars contain brake fluid that does not protect against corrosion of the hydraulic electronic control unit, NHTSA said.

In late October, Hyundai recalled 27,500 Genesis sedans in the U.S. to address the problem.

"If the module corrodes, reduced brake effectiveness may result, increasing the risk of a crash," said NHTSA in its summary of the expanded recall.

The cars were built from April 30, 2008 through March 28, 2012.

Hyundai dealers will inspect the HECU module for proper operation and will replace the modules as necessary. Hyundai will replace the factory brake fluid in those vehicles that have not previously had the factory brake fluid replaced.

The recall is expected to begin in December. Owners can contact Hyundai at 1-800-633-5151.

Previously, NHTSA opened a probe into 40,000 Genesis sedans after receiving 23 consumer complaints alleging reduced brake effectiveness. One reported crash was linked to the investigation. No injuries or fatalities were linked to the investigation.
