The short answer

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

Reduced brake function can extend the distance required to stop, increasing the risk of a crash or injury.

Honda (American Honda Motor Co.) is recalling certain 2016-2020 Acura ILX vehicles.

Contaminated brake fluid may cause a seal inside the brake master cylinder to deform, which can cause an internal brake fluid leak and reduce brake function.
