I was driving my vehicle on the freeway going 70 miles per hour and all the sudden my vehicle had pretty much came to a complete stop and if I hadn't had my seatbelt on, I probably would have went through the windshield.
The speedometer stops working correctly. While traveling at highway speeds the speedometer will read anywhere between below 0 mph and 30 mph. It happens regardless of the weather. There have been multiple occurances that the speedometer is working correctly, (confirmed by calculations using time, mile markers & odometer readings,) and at any point during travel it will stop and the needle is observed to gradually drop below the 0 mph mark. Sometimes restarting, whether by turning off the ignition or using the autostart to remove the key while leaving the vehicle running, will temporarily correct the problem. The problem was noted by an independent mechanic at the end of September while addressing potential transmission issues. (which also has not been resolved. The mechanic was unable to find a cause to "hard shift" problem that began several months ago. ) the currently mileage on the vehicle is approximately 81,200 miles. It is being taken to a mechanic this week to address the issue.
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.
