another one that is common is the encoder motor, im not sure if its related to ABS or the transfer case. many times when peopel get the messages reduced power, service 4wheel, traction failed, or something of that nature it is the encoder motor. i put this one down as a transfer case problem, even though it may not be, not really sure.
also had the break groan under heavy braking, but it seemed to go away by itself.
had body mounts issue, fixed.
and some other little things.
overall im still very happy.
