Problems with 2004 Buick Rendezvous EQUIPMENT

Speedometer, rpm gauge, fuel gage, and temperature gauge give false readings. speedometer is the most important and gets stuck on different mph randomly. currently it will not go above 20 mph. research online suggest that the instrument cluster has 6 motors and one or more have failed. i called gm before the bankruptcy and they noted this had happened on some of their other makes and they were aware of complaints concerning the buick rendezvous, but there were not enough complaints to warrant a recall. they only offered to maybe help with the computer check, but would not assist with the $400 to $500 gm service charge to fix the instrument panel motors. *tr

Rear differential will not stop groaning on any turn. rear differential now has to be replaced and the car only has 80,000 miles on it. we also have to replace the rack and pinion. the total costs associated with both these will be well over $5,000. it is effecting the turning process when i need to turn the car. also have a rack and pinion failure. the steering column completely locked up and the towing company had to put oil all over where the car was parked and slide it up to the cable to tow the car. entire steering mechanism replaced but now the rack and pinion has to be replaced. i think it is due to the steering column issue. that is when it started. *tr

2004 buick rendezvous awd light came on and has never gone off. it came on when we had less than 30k miles on the car. we have had our car to many, many mechanics. none are able to fix this problem. one told us we needed all new tires, we bought new tires, one said it was the alignment we had it aligned. one mechanic went through the car and charged us 3 hours of labor to tell us that he did not know what was wrong and nothing appeared to be wrong. another suggested we contact the dealer must be a central computer system defect. called the dealer and he stated there were no warnings on this defect. awd is something we wanted when we purchased the vehicle. i have done a lot of research online and many other owners of this vehicle have had the same problem many, many mechanics and no fix to the problem. the owner's manual states that without this working it poses a safety hazard to the driver and occupants. we want to get this repaired but can't afford to keep spending money to investigate a problem no one can fix. kindly investigate this. *tr

Vehicle stalled while stopped at intersection - occurred twice in 2 days. subsequently vehicle experienced excessive cranking to start - twice. orange buick serviced the vehicle and repaired a wire harness that had been worn. 2 days later while driving the vehicle at 30 mph the vehicle lost all power (engine and electrical), i had to turn on the flashers and pull on to the shoulder. once the vehicle was stopped i put it in park and it restarted. however, the 'traction control off' light was on and after pressing the button it remained on. *jb
