In the affected vehicles—2005-2007 Honda Odyssey and Acura RL models—if any fluid other than the original brake fluid is used in the system, a seal in the brake master cylinder can leak, resulting in Honda says that there have not yet been any accidents connected to the issue.
If this sounds familiar, it is. It's the same issue that prompted Toyota to recall 1.5 million Toyota and Lexus vehicles globally this week, including 740,000 in the U.S. Honda and Toyota had used the same supplier for the components: Advics Company, in Japan.
Although the automaker hadn't yet issued any information regarding the recall effort, it's suspected that the fix will compare to what Toyota and Lexus offer—involving a redesigned brake master cylinder cup.
Honda told several news outlets that a brake fluid warning light would illuminate before there's any braking performance loss; and if owners do see that warning light, they should take their vehicle to a dealership immediately.
