"Service 4WD" warning constantly comes
on. 4WD now doesn't work at all. The
truck has already spent 10 days in
service departments (I've only owned
it for 3 months). The power windows
failed, the radio stopped working, and
the A/C went out. They've been able to
fix everything but the 4WD/Transfer
case problems. First it was
a "software update". Then it was
a "control module". Then it was
an "encoder motor". They finally
admitted they can't fix it. To make
things worse, GM isn't backing it up.
This is absolutely the worst truck
I've ever owned and it only has 4,000
miles on it.
XM radio, Duramax/Allison combo (great
power and great tranny pulling and
braking capability), leather seats.
Reliability of this vehicle is
terrible. Love the truck, hate all the
problems. I think I'm going to a Dodge
