Buick Rendezvous Acceleration problems by year

My vehicle has been picking up speed for no reason. The vehicle was not taken to nor taken to a dealer for diagnostic testing or repairs. Also, the fuel pump is not working. I can fill it up with gas and the light will still turn on. Maybe after driving for a couple miles or making a turn the light will turn off. *Tr

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...

At 65 miles per hour on a highway in rich hour traffic my vehicle stalls out and displays 2 lights 1."Reduced engine power" "service traction control system" or something to that effect. The car will not start for 3-5 minutes. Then restarts and continues to do the same thing another 5-7 times before I was able to get to a safe location. When hooked up to a code reader the code that displayed was co240 abs powertrain control module.. This is extremely dangerous. *Tr

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...

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...

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...

5 Minutes after being on the highway at 70 miles per hour the vehicle started dropping speed and message center started showing low battery, lights problem, service engine soon, brake fluid low, windshield wiper fluid low, low tire pressure, security service. Also, when I come to a stop the engine shuts off by itself as a low power, few minutes later, starts back up and can keep driving but hitting the gas pedal and releasing it after a few seconds at a time to recharge the battery so it would not shut off again....
