You would think buying a 4x4 truck, the "4x4" part of it would actually work, not only have I heard multiple complaints about the 4x4 engaging at 70+ mph on people, myself and others are experiencing blinking 4x4 lights that wont stay on, the truck refuses to go into 4x4, then once it does after the 100th button push, it wont come out of 4 wheel drive back into 2hi. Never again will i but a Chevy Colorado/Canyon. Nor do I recommend anyone else to, if I didn't owe more than this crap is worth it would have been gone a loooonnnnggg time ago.
