2007 GMC Yukon

The 2007 GMC Yukon is a full-size SUV known for its spacious interior, towing capability, and comfortable ride. Engine options included the 4.8L Vortec V8 (295 hp, 305 lb-ft torque), the 5.3L Vortec V8 (320 hp, 340 lb-ft torque), and the 6.0L Vortec V8 (366 hp, 380 lb-ft torque). All engines were paired with a 4-speed automatic transmission (4L60-E/4L65-E). Owners often appreciate the Yukon’s spaciousness and ability to haul cargo or passengers, but some dislike the poor fuel economy and potential for costly repairs as the vehicle ages.

Engine

4.8L Vortec V8
