ELECTRICAL SYSTEM
Owners of the 2019 Acura MDX frequently report issues with the auto start/stop system, which can unexpectedly shift the vehicle into neutral, leaving drivers temporarily unable to move. This problem often occurs when the vehicle is stationary, such as at traffic lights, and typically requires the driver to restart the car, posing a potential safety risk in traffic. Complaints also highlight simultaneous warning light activations, including emissions, parking brake, and SH-AWD system faults, often accompanied by low voltage error codes. These electrical issues are commonly reported around the 30,000 to 60,000-mile range. A small number of reports describe total vehicle shutdowns while driving, which could lead to dangerous situations. Fire risk is mentioned in one complaint related to a fuel pump defect, though details are limited.

UNKNOWN OR OTHER
Owners report that the 2019 Acura MDX frequently experiences issues with the auto start/stop feature, which can cause the vehicle to stall at intersections or in traffic, leading to dangerous situations. Complaints frequently mention that this problem persists even after recall repairs, and it tends to occur in high-traffic areas, creating a risk of rear-end collisions. Another common issue involves the front windshield camera malfunctioning, often attributed to heat exposure, which disables essential safety systems like collision mitigation and lane departure warnings. These problems typically arise within the first 47,000 miles, with some reports indicating ongoing issues despite attempted repairs. Safety implications include potential loss of vehicle control and increased accident risk, which is crucial information for prospective buyers.

ENGINE
Owners report several recurring engine-related issues with the 2019 Acura MDX. Complaints frequently mention the vehicle entering a "limp mode" or stalling unexpectedly, often without warning lights, at mileages ranging from approximately 45,000 to 67,150 miles. Multiple owners describe problems with the engine auto stop feature, which sometimes fails to restart the engine at traffic lights, necessitating a manual restart. Additionally, some owners express concerns about unresolved recalls related to engine components, which they are unable to address due to unavailable parts.

FORWARD COLLISION AVOIDANCE
Owners of the 2019 Acura MDX frequently report issues with the Forward Collision Avoidance system, particularly the Automatic Emergency Braking (AEB) and associated camera components. Common symptoms include unexpected braking activation without any apparent obstacles, often leading to abrupt stops and near-miss rear-end collisions. Multiple complaints highlight failures in the camera system, which triggers various dashboard warnings such as "Collision Mitigation Problem" and "Lane Keeping Assist Problem." These issues often occur intermittently and can persist despite servicing, with reports indicating occurrences as early as 2,000 miles and around 41,000 miles. The safety implications are significant, as the unexpected braking can pose a risk of accidents, especially in traffic.

SERVICE BRAKES
Owners of the 2019 Acura MDX frequently report issues with the vehicle's braking system, particularly the collision sensor activating without obstacles, causing the car to brake spontaneously. This issue is highlighted by multiple owners and is noted to increase in frequency. Additionally, some owners describe a stiff brake pedal that requires excessive force to operate, particularly after the vehicle has been powered off for some time. One report involves a crash where the brakes failed to respond at low speed, resulting in a collision with a pole at approximately 37,000 miles. These complaints suggest potential safety concerns due to unexpected braking and brake pedal stiffness, which may be important for potential buyers to consider.
