Infotainment System Freezing and Slow Boot
The infotainment system frequently freezes, takes over 30 seconds to boot (especially in cold weather below 50°F), or resets itself while driving. Apple CarPlay connections drop, the navigation screen goes blank, and the system may display error messages. The touchpad input can become unresponsive.
Acura has released multiple software updates to improve infotainment stability and boot times. Visit the dealer for the latest firmware update. In severe cases, the infotainment control unit may need to be replaced. A hard reset (holding the power button for 10+ seconds) can provide temporary relief.
Est. Cost: $0 for software update; $800 - $2,000 for control unit replacementPassenger Seat Weight Sensor Malfunction (Recall)
The front passenger seat weight sensor may crack and short-circuit, causing incorrect airbag status indication. The airbag may fail to suppress for a child seat or deploy unintentionally during a crash, increasing the risk of injury.
Honda issued a recall to replace the front passenger seat weight sensors free of charge. Contact your Acura dealer or check owners.acura.com/recalls with your VIN.
Est. Cost: Covered under recallSteering Tie Rod End Loosening (Clunk/Knock Noise)
A clunk, click, or knock-type sound is heard from the steering area while turning, particularly at low speeds during parking maneuvers. The noise is caused by an outer tie rod end nut that has become loose, which can eventually affect steering precision and alignment.
Acura issued a TSB to inspect and retorque the outer tie rod end nuts. If the nut or tie rod end is damaged, replacement is necessary. An alignment check should be performed after the repair.
Est. Cost: $100 - $400Premature Front Brake Wear and Noise
Owners report premature front brake pad wear, sometimes needing replacement before 20,000 miles, along with squealing, groaning, or grinding noises during light braking. The issue is attributed to the heavy vehicle weight and aggressive brake pad compound selection.
Have the brakes inspected for uneven pad wear and rotor runout. The dealer may install updated brake pads with a different friction compound that reduces noise. Resurfacing or replacing the rotors may be needed if they are scored. Regular brake inspections every 10,000 miles are recommended.
Est. Cost: $300 - $800 per axleFuel Injection ECU Software Error (Type S Recall)
On MDX Type S models, a software error in the fuel injection electronic control unit (FI-ECU) may cause the engine to stall or lose power unexpectedly. The turbo 3.0-liter V6 may hesitate, misfire, or shut off while driving.
Honda issued a recall for 2022-2025 Acura MDX Type S models to reprogram the FI-ECU software free of charge. Contact your Acura dealer with your VIN to schedule the update.
