2019 Chevrolet Suburban 3500 HD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 Suburban 3500 HD.

The 2019 Chevrolet Suburban 3500 HD occupies the heavy-duty end of Chevrolet's full-size SUV lineup, a body-on-frame platform engineered to deliver truck-grade capability within a passenger-oriented package. Its 8.0-quart engine oil capacity, paired with a 0W-20 viscosity specification, points to a substantial powertrain that nonetheless adheres to modern lubrication standards. In the context of the Suburban 3500 HD's reliability history, the 2019 model year stands as a particularly clean data point, with just two owner complaints concentrated in the steering and service brake systems and zero recalls recorded—an uncommon combination for a heavy-duty vehicle of this size and complexity.
