DETROIT — Hyundai decided to recall about 27,500 Genesis luxury cars Monday, just a few hours after the US government opened an investigation into problems with their brakes.
The automaker said the recall covers cars from the 2009 through 2012 model years. Hyundai sold about 69,000 Genesis models, and about 60 percent of them already been repaired through a company service campaign that began in March, a spokesman said.
Owners will be notified of the recall by mail starting in November, and dealers will pick up the cars and bring out a loaner vehicle, spokesman Miles Johnson said Monday. Anyone who wants to get their car checked and repaired before that can call their dealer, he said.
Dealers will change brake fluid in the cars and inspect the electronic brake control modules to see if they need to be replaced. Johnson said fluid in the cars do not have a corrosion inhibitor. As a result, a gel can build up on valves in the braking system, causing a loss of brakes.
The new fluid will have a corrosion inhibitor additive, Johnson said. Any brake control modules with gel on the valves will be replaced, he said. ‘‘We will take care of the customer on this deal,’’ he said.
