Body SUVEngine 3.0L DieselTransmission Automatic 8-spd
The 2019 Jeep Grand Cherokee, built on the WK platform, remains a stalwart in the midsize SUV segment, offering a refined yet rugged presence with its available 3.0L diesel engine paired to an 8-speed automatic transmission—a combination that delivers a respectable 26 mpg on the highway while maintaining the model’s characteristic towing capability. With a substantial 8.0-quart oil capacity requiring 5W-40 viscosity, this powertrain underscores the vehicle’s balance of efficiency and durability, though its 356 owner complaints and seven recalls in this model year reflect a reliability record that, while improved from the 2014 peak of 2,369 complaints, still demands careful attention to hydraulic brake service and routine maintenance. Positioned mid-pack in the Grand Cherokee’s broader complaint history, the 2019 iteration represents a modest step forward in dependability, though it remains a model where proactive ownership is key to long-term satisfaction.
