Honda recalls 2020 Acura ILX vehicles with potentially reduced brake function due to contaminated brake fluid causing internal leaks. Owners must have brake master cylinder replaced free by dealers.
Reduced brake function can extend the distance required to stop, increasing the risk of a crash or injury.
Honda is recalling certain 2020 Acura ILX vehicles because contaminated brake fluid may cause internal leaks that reduce braking power. This increases the risk of crashes or injuries if the vehicle stops suddenly.
Contaminated brake fluid can cause seals inside the brake master cylinder to deform, leading to internal leaks. This reduces brake function, requiring longer stopping distances and increasing crash risk.
Owners of 2020 Acura ILX vehicles with VINs listed in the recall. Drivers who frequently stop in heavy traffic or on wet roads are at higher risk.
