The 2017 Acura MDX Sport has 3 recalls, the most serious involving fuel hoses that were misrouted during assembly and can wear against nearby components, leading to a fuel leak. Note that all three recalls affect only the Sport Hybrid trim. On the brake side, rear brake caliper pistons may have an insufficient coating that causes gas pockets to form inside them, reducing braking force and increasing stopping distances. There is also a lighting concern: moisture can get into the tailgate lid lights and cause both the tailgate lights and taillights to go out, making the vehicle harder for other drivers to see from behind.
