The Tahoe has a luxurious and quiet interior, decent second- and third-row seats, and available features such as blind-spot monitoring and cross-traffic alert. Beyond that, fuel economy from the 5.3-liter V8 and six-speed automatic is 16 mpg. But the engine doesn't feel responsive enough in everyday driving. The touch-screen infotainment system is easy to use. The ride is stiff, although the Magnetic Ride Control suspension on LTZ trims improves ride comfort and handling response and capability. Properly equipped versions can tow 8,500 pounds. But car-based SUVs have better handling and are more efficient. Lane-keeping assist is now available. Reliability has been much below average.
