The Tahoe has a luxurious and quiet interior, but the ride is too stiff and the third-row seat is tight. In addition, the 5.3-liter V8 and six-speed automatic combine to form a lackluster powertrain that returned 16 mpg overall. The touch-screen infotainment system is easy to use, and the front seats are very comfortable. The Magnetic Ride Control suspension on LTZ trims improves ride comfort, as well as handling response and capability. Properly equipped versions can tow 8,500 pounds. But if towing isn't your main concern, car-based SUVs drive better and are roomier. Lane-keeping assist is now available, joining the already-available blind-spot monitoring and cross-traffic alert systems. Reliability has been well below average.
