1. Knocking in front end, intermittent steering shaft is out. I have been on waiting list since September 2003 and still not fixed. (in a wreck this component is what keeps the steering rod from projecting into the cab; per Chevrolet mechanic). 2. Sept. 2003 transmission: grinding/vibrating sound in the middle of vehicle (think this is my torque converter), neutral position from a complete stop and while driving. Been in shop on 2 occasions and still not fixed, mechanic says the vehicle computer doesn't show any problems, so they won't fix it! 3. Front differential leaking. Jan. 2004 to be fixed when steering shaft gets fixed! 4. Passenger heaters come on by themselves. Nov. 2003 still not fixed 5. Front driver's seat won't hold memory settings. Nov. 2003 still not fixed.
