ELECTRICAL SYSTEM

Owners of the 2024 Acura MDX report several issues related to the electrical system, with common problems including unexpected activation of the automatic braking system and delays or failures in the rearview and 360-degree camera systems. Complaints frequently mention the vehicle stalling or shutting off unexpectedly, sometimes shifting into park or neutral without warning, particularly at low speeds or when stopped. These issues often occur around 9,000 to 9,873 miles, with some owners noting repeated occurrences. Safety implications are evident, as some owners describe near-miss situations due to sudden stops or stalls in traffic. Additionally, corrosion on battery terminals is observed in at least one case, contributing to stalling issues.

UNKNOWN OR OTHER

Owners of the 2024 Acura MDX report issues primarily related to the HVAC system and sunroof glass. Multiple complaints describe a musty odor from the HVAC system, suggesting potential mold or mildew presence, with some owners noting this requires costly cleaning and filter replacement. Additionally, several owners report incidents of the sunroof glass spontaneously shattering, with one case resulting in injuries from flying glass. These issues are reported at various mileage points, with one sunroof incident occurring under 30,000 miles. Safety implications include potential respiratory issues from mold exposure and the risk of injury from sunroof glass breakage.

Severity signals: 0 crash, 0 fire, 2 injury reports

STEERING

Owners of the 2024 Acura MDX report issues with the steering system, often involving sudden loss of power steering assist, making the steering wheel difficult or impossible to turn. Complaints frequently mention multiple warning messages appearing on the dashboard, including alerts for the electric power steering system, collision mitigation braking system, and road departure mitigation system. These issues tend to occur while driving, with some reports indicating the vehicle was in motion on highways or expressways. Owners express concern over safety implications, particularly the potential for loss of control, though no crashes are reported. The steering problems are sometimes linked to malfunctioning sensors or the steering angle sensor, and some vehicles have required replacement of the steering rack or other components.

VEHICLE SPEED CONTROL

Owners of the 2024 Acura MDX report issues with the vehicle speed control system, primarily involving cruise control and unintended deceleration. Common symptoms include the cruise control failing to maintain set speeds, particularly when transitioning from downhill to uphill driving, with speed dropping significantly before recovering. Additionally, some owners describe the vehicle decelerating abruptly from highway speeds to as low as 6 MPH without warning, and experiencing jerking motions while driving at consistent speeds. These issues are reported at mileages ranging from 2,500 to 7,000 miles. Safety implications are noted, such as near collisions due to throttle lag and instances where the vehicle stalls in traffic, requiring towing. These patterns suggest potential reliability concerns for prospective buyers.

POWER TRAIN

Owners of the 2024 Acura MDX report issues with delayed acceleration, particularly when attempting to merge or avoid obstacles, suggesting potential throttle or transmission concerns. Complaints frequently mention the vehicle's inability to accelerate promptly, with one owner noting repeated dealership visits and unsuccessful computer resets. Another owner describes erratic transmission behavior, where the vehicle unexpectedly shifts gears and surges, alongside warning messages for parking sensors and brake performance failures. These issues are reported at low mileage, around 9,747 miles, and include symptoms like gear shifting irregularities and unintended acceleration, which could impact vehicle control. Buyers should consider these patterns of power train issues when evaluating the vehicle's reliability.
