Recalls for the 2020 Acura MDX: 8
The rear subframe may corrode at the suspension mounting points, which can result in rear suspension component failure. Failure of rear suspension components, such as the rear control arm, can cause a loss of vehicle handling and control, increasing the risk of a crash or injury.
The front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally during a crash. Air bags that deploy unintentionally during a crash increase the risk of injury.
Moisture may enter the tailgate lid light assembly and wiring harness, which can cause the interior and exterior lights to fail, including the lid lights, position lights, license plate lights and taillights. Vehicle lights that fail to illuminate can decrease visibility and increase the risk of a crash.
The front passenger seat weight sensor may crack and short circuit, failing to suppress the air bag as intended. An air bag that deploys unintentionally during a crash can increase the risk of injury.
The fuel pump inside the fuel tank may fail. Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.
Due to a manufacturing error, the connecting rod bearing in the engine may wear and seize, damaging the engine. A damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury.
The tie rod fastener that connects the brake booster and the brake master cylinder may have been improperly assembled during manufacturing, which can cause the brake master cylinder to separate from the booster assembly. Brake master cylinder separation can cause a loss of brake function and increase the risk of a crash.
The low-pressure fuel pump inside the fuel tank may fail. Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.
