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.

Intermittent loss of power, loss of ABS brakes and loss of AWD. When you apply pressure to the gas pedal (accelerator) if you depress the pedal for what feels like over a 1/2 inch you lose power and the rpms go sky high and you can hear it trying to rev up. To get going you have to release the gas and press lightly. I loss power, esp. Going uphill since it needs more to go, but you can't give it more gas else it won't go. I and my fianc were almost hit in an intersection because of this loss of power. You can gain speed, but very slowly and anytime you depress the gas pedal further it again fails. Replaced three wheel bearings, all brakes, two calipers and the throttle position sensor. Nothing shows on the readout except for the front bearings aren't reading right, but they're brand new and have been re-checked for defect. Still that hasn't fixed the issue. Upon problem has actually been occurring for almost two months now.

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 doesn't 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 don't have $900 to fix it. I am always putting wheel hub assembly on it. That gets very expensive..

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.

While traveling from Utah to Iowa on interstate 80 with the cruise control set at roadway speed. After some time the speedometer kept climbing while the speed of the vehicle decreased. After stopping at a rest area the speedometer never moved. It was just stuck at approximately 112 mph. Luckily we were given a gps with speedometer built in as a gift. Leaving the rest stop, we continued our journey, and by the time we made it to Iowa the speedometer gauge was facing straight down whether we were stopped or driving road speeds. We did not take it to a dealership immediately because we have three small children and after sitting in the car that long, we could not justify sitting at a dealership for hours on end. Around five days after arriving in Iowa, the speedometer started working again. This greatly confused me, because when something breaks on a vehicle, it tends to stay broken. On our travels back to Utah the samething happened to the speedometer, so as soon as we arrived in Utah, I dropped my spouse and children off at home, and took it to the dealership. I explained the problem and my situation and they came to the conclusion of a loose or broken connection deep behind the dash. Here is the "kicker", according to them there was no recall for this said problem and that it would cost $600 to fix. As I am not the original owner of the vehicle it was purchased as is from a dealership in Iowa. I unfortunately do not have $600 to spend to repair the vehicle. We now have 86,365 miles on a vehicle that the speedometer no longer works. I cannot see how it is not a safety recall, but I am not in big business. So I feel I am taking the appropriate steps to fix the problem for not only myself, but all the others' comments that I have read.

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.

I purchased a new 2005 Buick Rendezvous cxl and have had to replace the front left bearing and hub assembly in July 2008, then in April 2009 the right front control arm bushing separated and the dealer replaced the hub assembly again, then in Sept.2010 the bushings and front control arm on the front left side needed to be replaced again. I also had to have the throttle body replaced because of acceleration problems. So far no one has been hurt or any accidents, but how long and how many bearings and bushings and assemblies do I need to replace before a recall is issued?

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 vehicle struck a chain, which was strung between two post, before the consumer could slam on the brake and shut the vehicle off. The consumer is concerned that this may happen again.
