I like the design and power too but it seems itīs not so reliable; General Motors is recalling 78,004 GMC Envoy and Chevrolet Trailblazer models built between January and August, 2001 to recalibrate the transfer case control module. On models equipped with 4-wheel drive, the calibration of the transfer case control module could cause insufficient high-speed gear engagement. If the gear is not engaged, the vehicle can roll when the transmission is in "Park.
