general problems of the 2005 Buick Rendezvous

My speedometer has stopped working. Mostly is reads 120 mph when I am setting still. Because it fluctuates from moving or not moving. But never correctly. I have been reduced to relying solely on a gps speedometer.

When I would start my car in the morning, I would get a overwhelming gas smell in my to point of me thinking gas was leaking underneath my and I would get out and check and nothing. I took it to a mechanic and asked him if the car was leaking gas and he said no. I'm constantly adding power steering fluid to my vehicle at least twice a month . And recently my speedometer needle has started sticking and sometimes not working at all. Ironically my gas needle is always fluctuating throughout my car trips. I'm so nervous when I drive because I think I'm about to run out of gas even though I may have recently added gas to the car. This may sound simple but the gas fumes are making me sick and my two kids especially since all of us suffer from asthma. Please provide a resolution or fix for these unhealthy incidents.

Stepper motors in the instrument cluster failing. One gauge goes bad they all do. Cannot determine how much gas I have or how fast I am going cause all needles point down or stop at 70. I can be at a red light , completely stopped and it says I am going 110 mph. I have a 4 year old, a 5 year old, and a 5 month old in the back of the car. Its pretty scary for them as well. I have seen this is a common problem with gm made cars from 2000-2005. Wouldn't you think they would fix this by now? not happy with this car at all.

The speedometer stopped working properly and reads seriously erroneous speeds, both higher and lower than true speeds, which I checked with a gps unit. Apparently this is due to defective stepper motors in the instrument cluster from what I read on the internet. Gm needs to recall and fix these. The defect can cause drivers to travel at unsafe speeds, as they are misled by the speedometer reading.

My wife was driving down the interstate at 70 mile per hour when the accelerator pedal jammed itself down speeding up the car. When she noticed that this had happened she hit the brakes and nothing happened. The brakes seemed as though they were not working. Not knowing what else to try she then attempted to engage the emergency brake. It did not engage, it kept going down then just coming right back up. Still not knowing what to do she shifted down to low gears slowing her down. Still out of control she hit a ditch which shut down the engine finally bringing the car to a stop. I just thought that this should be brought to the attention of someone. She luckily was not injured but could have been though.

The car stopped automatically at a stop light on a major hwy. I thought quickly and put it in neutral thank you jesus it started. I could have been rear ended. That is a major problem it does it periodically. I never know when its going to do it. . . I have replaced the wheel hub assembly on the rear 5 times and 2 on the front. . My gas gauge goes crazy or doesnt work at all. My speedometer has quit working and the other gauges work when they feel like it. It seems. I have had people check the vehicle out no one seems to know exactly what is wrong they say the cluster is out because of the gauges I dont have 900. 00 to fix it. I am always putting wheel hub assembly on it. That gets very expensive. .
